'''DMCA 1201 and the Right to Reverse Engineer''' refers to the ongoing conflict between technology companies' use of Section 1201 of the Digital Millennium Copyright Act to prevent consumers from accessing devices they own, blurring the line between illegal hacking and legitimate reverse engineering to maintain control over products after their sale.
This addresses the widespread & harmful misconception that breaking a digital lock or modifying software behavior is '''always''' ''"illegal hacking."'' In truth, U.S. law - while flawed - draws a clear line between lawful reverse engineering & criminal activity. Companies often exploit this confusion to suppress ownership rights, discourage repair, and shut down interoperability under the guise of protecting security or intellectual property.


==Background==


'''Section 1201 of the Digital Millennium Copyright Act''' (DMCA 1201), enacted in 1998, prohibits the circumvention of digital rights management (DRM) technologies that protect copyrighted works. While originally intended to prevent piracy of movies, music, and software, companies have increasingly weaponized this law to prevent consumers from exercising ownership rights over devices they have purchased.
This article seeks to clarify legal distinctions, correct the record, & explain why reverse engineering your own device to restore or preserve its functionality is not a crime.
==What section 1201 is for==


The law makes it illegal to bypass DRM protections regardless of intent, and also prohibits manufacturing or distributing tools that enable circumvention. However, it includes exemptions for activities like security research, accessibility modifications, and educational uses, though these exemptions have periodic reviews by the Library of Congress.
'''Section 1201 of the Digital Millennium Copyright Act''' (DMCA), passed in 1998, prohibits the circumvention of ''"technological protection measures"'' (TPMs) used to control access to copyrighted works. It also prohibits the distribution of tools designed primarily for circumvention.


==Legal reverse engineering vs. illegal hacking==
What makes Section 1201 controversial is that it penalizes circumvention '''regardless of whether any copyright infringement occurred'''. In other words, even if you just want to modify or fix a product you legally own, you may still be in violation if the manufacturer wrapped it in DRM.


There is a legal distinction between reverse engineering and illegal hacking that companies often deliberately try to blur to maintain control over devices.
To soften this, Congress allowed for temporary exemptions reviewed every three years by the Library of Congress. These exemptions currently include certain cases of repair, diagnosis, security research, accessibility, & jailbreaking of phones. However, the process is burdensome, narrow, & inconsistently applied.


===Reverse engineering===
==Legal Reverse Engineering vs. Illegal Hacking==


'''Reverse engineering''' is the legal practice of analyzing a product to understand how it works, typically through examination of its behavior, disassembly of hardware, or analysis of software interfaces. In the United States, reverse engineering has been protected under copyright law when done for legitimate purposes such as:
Contrary to what some CEOs & PR departments have said, '''reverse engineering is legal in many contexts''' - especially when done for purposes of interoperability, repair, research, or personal use.


*Understanding how a device functions for personal use
===What Counts as Legal Reverse Engineering===
*Creating interoperable software or hardware
*Security research and vulnerability findings
*Academic research and education
*Repairing devices you own


Courts have upheld the right to reverse engineer products, recognizing it as essential for innovation, competition, and consumer rights.
The U.S. legal system has repeatedly upheld the right to reverse engineer in certain contexts, particularly when the intent is to enable interoperability or understand how something works. Notable court decisions include:


===Illegal hacking===
*'''Sega Enterprises Ltd. v. Accolade, Inc.''' (1992): The Ninth Circuit ruled that disassembling code to understand how to make compatible software was fair use.<ref>{{Cite web |title=Sega Enters. Ltd. v. Accolade, Inc.,
977 F.2d 1510 (9th Cir. 1992) |url=https://www.copyright.gov/fair-use/summaries/segaenters-accolade-9thcir1992.pdf}}</ref>


'''Illegal hacking''' involves unauthorized access to computer systems, networks, or data belonging to others. This includes activities such as:
*'''Sony Computer Entertainment v. Connectix Corp.''' (2000): The court affirmed that reverse engineering to create a competing product (a PlayStation emulator) was legal & transformative.<ref>{{Cite web |title=Sony Computer Entm’t, Inc. v. Connectix Corp.,
203 F.3d 596 (9th Cir. 2000 |url=https://www.copyright.gov/fair-use/summaries/sony-connectix-9thcir2000.pdf}}</ref>


*Breaking into computer networks without permission
*'''Lexmark Int'l v. Static Control Components''' (2004): The Sixth Circuit ruled that Static Control could reverse engineer printer firmware to enable third-party toner cartridges. The court pointed out that interoperability trumped DMCA anti-circumvention claims.<ref name="lexmark">[[wikipedia:Lexmark_International,_Inc._v._Static_Control_Components,_Inc.|https://en.wikipedia.org/wiki/Lexmark_International,_Inc._v._Static_Control_Components,_Inc.]]</ref>
*Accessing confidential data on systems you don't own
*Distributing pirated copyrighted content
*Using reverse engineering knowledge to commit crimes


The key distinction is that illegal hacking involves accessing systems or data you don't have rights to, while reverse engineering involves analyzing products you already own.
*'''Chamberlain Group v. Skylink Technologies''' (2004): The Federal Circuit held that creating universal garage door remotes through reverse engineering was legitimate, establishing that DMCA violations must connect to actual copyright infringement.<ref>{{Cite web |title=The CHAMBERLAIN GROUP,

Defendant–Appellee.
No. 04–1118.
United States Court of Appeals,
Federal Circuit |url=https://www.law.berkeley.edu/files/Chamberlain_Group_v_Skylink_Technologies.pdf}}</ref>


==How companies blur the distinction==
*'''DSC Communications v. DGI Technologies''' (1995): Courts held that disassembling firmware to create compatible microprocessor cards constituted fair use, establishing that functional elements accessed only through disassembly can be lawfully copied.<ref>{{Cite web |title=DSC Communications Corp. v. DGI Technologies, Inc., 898 F. Supp. 1183 (N.D. Tex. 1995) |url=https://law.justia.com/cases/federal/district-courts/FSupp/898/1183/1464449/}}</ref>


Large technology companies have worked to confuse legal reverse engineering with illegal hacking to prevent consumers from exercising ownership rights over purchased devices.
*'''Assessment Technologies v. WIREdata''' (2003): The Seventh Circuit ruled that reverse engineering to access public domain data trapped within copyrighted software is permissible, preventing copyright from creating "locks" on non-copyrightable information.<ref>{{Cite web |title=Assessment Technologies of Wi, Llc, Plaintiff-appellee, v. Wiredata, Inc., Defendant-appellant, 350 F.3d 640 (7th Cir. 2003) |url=https://law.justia.com/cases/federal/appellate-courts/F3/350/640/625754/}}</ref>


===Weaponizing DMCA 1201===
Legal reverse engineering generally includes:
*Analyzing software you own for repair or maintenance
*Studying protocols to make devices work with third-party tools
*Extracting firmware from your own hardware
*Building alternate apps that communicate with your devices
*Publishing technical findings that don't contain copyrighted code
*Good faith security research under DMCA exemptions


Companies embed DRM technologies in devices and then claim that any attempt to understand or modify these devices violates DMCA 1201. This strategy allows them to:
===What Constitutes Illegal Hacking===


*Prevent third-party repairs by claiming repair tools "circumvent" DRM
Illegal hacking, by contrast, involves:
*Block connectivity with competing products
*Accessing remote systems without authorization
*Force consumers into expensive subscription services
*Bypassing login or authentication mechanisms on someone else's network
*Maintain control over devices after the sale
*Stealing or distributing copyrighted code without a license
*Tampering with systems in ways that compromise others' data or services
*Continuing access after explicit revocation (see '''Facebook v. Power Ventures''', 2016)<ref>{{Cite web |title=FACEBOOK, INC., a Delaware

===Misleading terminology===
The key difference is ownership & scope: Reverse engineering stays within the boundary of what you own. Hacking crosses into systems that you don't.


Technology companies frequently use inflammatory language to describe legitimate consumer activities:
==Current DMCA Exemptions (2024-2027)==


*Calling device modification "jailbreaking" or "rooting" to suggest criminal activity
The Library of Congress granted sweeping new exemptions in October 2024 that greatly expand repair rights:<ref>{{cite web |url=https://www.federalregister.gov/documents/2024/10/28/2024-24563/exemption-to-prohibition-on-circumvention-of-copyright-protection-systems-for-access-control |title=Exemption to Prohibition on Circumvention of Copyright Protection Systems for Access Control Technologies |publisher=Federal Register |date=October 28, 2024}}</ref>
*Referring to reverse engineering as "hacking" to imply illegality
*Claiming that accessing firmware constitutes "piracy"
*Describing interoperability efforts as "unauthorized access"


This deliberately misleading terminology conflates legal consumer activities with criminal hacking to discourage consumers from exercising their rights.
*'''Vehicle telematics data access''': Owners can now circumvent software locks to access, store, & share their vehicle's operations & diagnostic data.
*'''Commercial food preparation equipment''': New exemption for retail-level restaurant equipment repair ''(addressing the McDonald's ice cream machine problem)''<ref>{{Cite news |last=Bowman |first=Emma |date=November 3, 20245:00 AM ET |title=A new copyright rule lets McDonald's fix its own broken ice cream machines |url=https://www.npr.org/2024/11/02/g-s1-31893/mcdonalds-broken-ice-cream-machine-copyright-law |work=NPR}}</ref>
*'''Consumer devices''': Renewed exemptions for smartphones, tablets, smart TVs, & IoT devices
*'''Medical devices''': Continued exemption with FDA support, concluding it wouldn't "necessarily & materially jeopardize" device safety<ref>{{cite web |url=https://iamers.org/2024/07/fda-issues-letter-supporting-continuation-of-dmca-exemption-for-repair-of-medical-devices/ |title=FDA issues letter supporting continuation of DMCA exemption for repair of medical devices |publisher=IAMERS |date=July 2024}}</ref>
*'''Jailbreaking''': Expanded to cover smartphones, smart TVs, voice assistants, & routers for installing alternative software


==A real world example: the Futurehome case==
These exemptions require that circumvention be a ''"necessary step"'' for the permitted purpose & cannot facilitate access to other copyrighted works.


The Norwegian smart home company Futurehome provides a clear example of how companies use technical restrictions and legal intimidation to undermine consumer ownership rights, while deliberately mischaracterizing legitimate reverse engineering as "illegal hacking."
==Narrowing Computer Hacking Laws==


===The ownership model bait-and-switch===
The Supreme Court's 2021 decision in '''Van Buren v. United States''' fundamentally changed how courts interpret the Computer Fraud & Abuse Act (CFAA).<ref>{{Cite web |title=VAN BUREN v. UNITED STATES
CERTIORARI TO THE UNITED STATES COURT OF APPEALS FOR
THE ELEVENTH CIRCUIT
No. 19–783. Argued November 30, 2020—Decided June 3, 2021 |url=https://www.supremecourt.gov/opinions/20pdf/19-783_k53l.pdf}}</ref> The 6-3 majority adopted a "gates-up-or-down" test: you either have permission to access a computer system or you don't. Violating terms of service or using legitimately accessed data for improper purposes doesn't constitute ''"exceeding authorized access"'' under CFAA.


Futurehome originally sold its Smarthub as a one-time purchase with full functionality included.<ref>{{cite web |url=https://support.futurehome.no/hc/en-no/articles/28158944965277-FAQ-Subscription |title=FAQ Subscription - Futurehome |access-date=2025-07-14}}</ref> After the company declared bankruptcy in May 2025, the new owners FHSD Connect AS imposed a mandatory annual subscription fee of 1,188 NOK (approximately $117 USD) to continue using devices customers had already purchased.<ref>{{cite web |url=https://www.tek.no/nyheter/nyhet/i/alMe04/rasende-kunder-opplever-smarthjem-utpressing |title=Rasende og fortvile Futurehome-kunder: – Oppleves som utpressing |website=Tek.no |language=norsk |access-date=2025-07-14}}</ref>
This decision protects security researchers & reverse engineers who:
*Access publicly available systems
*Use credentials they were legitimately given
*Don't bypass technical access controls
*Violate only terms of service, not technical barriers


Customers who refuse to pay the subscription lose access to:
The Ninth Circuit applied this framework in '''hiQ Labs v. LinkedIn''' (2022), finding that scraping publicly accessible data doesn't violate CFAA since there are ''"no gates to lift or lower"'' on public websites.<ref>{{Cite web |title=HIQ LABS, INC. V. LINKEDIN CORPORATION, No. 17-16783 (9th Cir. 2022) |url=https://law.justia.com/cases/federal/appellate-courts/ca9/17-16783/17-16783-2022-04-18.html}}</ref>
*Mobile app functionality
*Automations and smart features
*Cloud-based controls
*Third-party integrations


The devices revert to basic manual operation only, making the smart home systems basically useless despite customers having paid for the hardware.
==Futurehome example:==


===Creating artificial dependence===
In May 2025, Norwegian smart home company Futurehome was acquired out of bankruptcy. The new owners, FHSD Connect AS, introduced a mandatory subscription model: customers had to pay an annual fee of 1,188 NOK (approx. $117 USD) or lose access to basic functionality like the mobile app, automation, & local APIs - even though those features were previously included in the one-time purchase price.<ref>{{cite web |url=https://www.tek.no/nyheter/nyhet/i/alMe04/rasende-kunder-opplever-smarthjem-utpressing |title=Rasende og fortvilte Futurehome-kunder: – Oppleves som utpressing |website=Tek.no |access-date=2025-07-14 |language=nb}}</ref>


Futurehome uses several technical mechanisms to enforce subscription dependence that go beyond legitimate security concerns:
When customers began exploring ways to restore lost functionality through reverse engineering, Futurehome CEO Øyvind Fries accused them of ''"illegal hacking"'' & threatened legal action.<ref>{{cite web |url=https://www.tek.no/nyheter/nyhet/i/mPm4xl/lover-50000-kroner-for-aa-gjore-futurehome-gratis |title=Lover 50.000 kroner for å knekke programvaren til Futurehome |website=Tek.no |access-date=2025-07-14 |language=nb}}</ref>


*'''Cloud-only authentication''': The devices cannot authenticate locally, requiring internet connectivity and Futurehome's servers to function
However, no evidence was provided that users were:
*'''Software locks''': Firmware prevents local control interfaces from operating without cloud verification
*Accessing Futurehome's servers without authorization
*'''API restrictions''': Third-party integrations are disabled without active subscriptions
*Distributing proprietary code
*'''Encrypted protocols''': Local communication uses proprietary encrypted protocols that prevent alternative software
*Compromising the privacy of others


These restrictions serve no consumer benefit and exist solely to maintain subscription revenue. The devices are physically capable of operating locally, as evidenced by their ability to function during the initial setup period before cloud connectivity is established.
Consumer rights advocate Louis Rossmann offered a $5,000 bounty for someone to create a way to use Futurehome devices locally without a subscription. His viewers began:
*Capturing network traffic from their own devices
*Analyzing firmware dumps from hubs they physically owned
*Attempting to restore functionality that had been removed post-sale
The purpose was to restore functionality customers had already paid for. Futurehome's management tried to frame this as a bounty for criminal activity.  


===The false "hacking" narrative===
==Other Examples with Legal Clarity==


In response to customer complaints and reverse engineering efforts, Futurehome CEO Øyvind Fries told Norwegian media that unauthorized access to their software would be considered "illegal hacking" and could result in criminal prosecution.<ref>{{cite web |url=https://www.tek.no/nyheter/nyhet/i/alMe04/rasende-kunder-opplever-smarthjem-utpressing |title=Rasende og fortvile Futurehome-kunder: – Oppleves som utpressing |website=Tek.no |language=norsk |access-date=2025-07-14}}</ref> This statement deliberately conflates:
*'''John Deere Tractors''': Deere has long fought independent repair efforts, but under pressure from state laws & exemptions granted by the Library of Congress, some tractor repair activities (such as accessing diagnostic software) are now explicitly legal.<ref>{{cite web |url=https://www.repair.org/stand-up-for-repair |title=Stand Up for Repair |publisher=Repair.org}}</ref> The FTC & state attorneys general sued John Deere in January 2025 for monopolizing agricultural equipment repair.<ref>{{cite web |url=https://www.npr.org/2025/01/15/nx-s1-5260895/john-deere-ftc-lawsuit-right-to-repair-tractors |title=FTC sues John Deere over farmers' right to repair tractors |publisher=NPR |date=January 15, 2025}}</ref>


*'''Legitimate activity''': Customers analyzing their own devices to restore paid-for functionality
*'''Sony PlayStation 3''' jailbreaking: Sony sued George Hotz (Geohot) after he jailbroke a PS3. While Sony sued him civilly, the case settled without establishing that his actions were criminal.<ref>{{Cite web |title=Sony and Hotz settle hacking case |url=https://www.bbc.com/news/technology-13047725}}</ref>
*'''Illegal activity''': Unauthorized access to Futurehome's servers or networks


This mischaracterization exemplifies how companies weaponize DMCA 1201 and anti-hacking laws to prevent consumers from exercising ownership rights over products they have purchased.
*'''Lexmark Printers''': As mentioned above, the Sixth Circuit ruled that making third-party toner cartridges work with Lexmark printers - despite digital locks - was not illegal.<ref name="lexmark" />


===The bounty controversy===
*'''United States v. Elcom/Sklyarov''' (2001-2002): Though Russian programmer Dmitry Sklyarov was arrested for creating Adobe eBook circumvention software, charges were dropped against him personally & his company ElcomSoft was acquitted, demonstrating prosecutorial overreach risks.<ref>{{cite web |url=https://www.eff.org/cases/us-v-elcomsoft-sklyarov |title=US v. ElcomSoft & Sklyarov |publisher=Electronic Frontier Foundation}}</ref>


The situation escalated when consumer rights activist Louis Rossmann offered a $5,000 bounty to anyone who could "crack the firmware" to make the devices work independently of Futurehome's subscription service.<ref>{{cite web |url=https://www.tek.no/nyheter/nyhet/i/nP4d/lover-50000-kroner-for-aa-gjore-futurehome-gratis |title=Lover 50.000 kroner for å knekke kildekoden til Futurehome |website=Tek.no |language=norsk |access-date=2025-07-14}}</ref> Rossmann clarified that he wanted to see if anyone could circumvent the software restrictions that prevent customers from using devices they had purchased.
=="Illegal Hacking" as a legal conclusion==


Futurehome's management characterized this as offering payment for "illegal hacking," despite the fact that:
Using words like "hacking" to describe legitimate reverse engineering is not a legal conclusion. Section 1201 of is written in a way that can make even normal ownership behavior sound suspicious. Courts have repeatedly ruled that '''reverse engineering, when done for lawful purposes, is protected'''.


*Customers legally own the physical hardware
==Key Legal Principles==
*The intent is to restore functionality customers had already paid for
*No unauthorized access to Futurehome's servers or networks would be involved
*The activity would constitute legitimate reverse engineering of owned devices


This represents a clear example of how companies mischaracterize legitimate consumer activities by using inflammatory "hacking" terminology to discourage people from exercising their ownership rights.
Courts now apply clear principles distinguishing lawful reverse engineering from illegal hacking:


===Why the "illegal hacking" claim is false===
'''Protected Activities Include:'''
*Lawfully acquiring software or hardware
*Analyzing it without circumventing authentication
*Conducting interoperability research under DMCA Section 1201(f)
*Accessing publicly available information
*Good faith security research with responsible disclosure


Futurehome's characterization of reverse engineering efforts as "illegal hacking" is legally and factually incorrect:
'''Risk Factors for CFAA/DMCA Liability:'''
*Bypassing passwords or authentication systems
*Continuing access after explicit revocation
*Accessing non-public systems
*Causing system damage
*Commercial exploitation of circumvention tools


'''What would actually be illegal:'''
The distinction often turns on technical circumvention - courts protect analytical activities that don't breach access controls while penalizing those who bypass passwords, authentication, or security measures.
*Breaking into Futurehome's corporate networks or servers
*Stealing proprietary code from Futurehome's systems
*Using reverse engineering knowledge to attack third-party systems
*Distributing Futurehome's copyrighted software


'''What is legal reverse engineering:'''
==Conclusion==
*Analyzing network traffic on your own local network
*Examining firmware extracted from devices you own
*Creating alternative software to control your own hardware
*Publishing information about how your devices work


The key distinction is ownership and intent. Customers who reverse engineer devices they purchased to restore functionality they paid for are exercising legitimate ownership rights, not committing crimes.
Reverse engineering is not a crime. Owning a product should mean controlling it. & efforts to restore, understand, or interoperate with devices you legally bought are not "hacking" - they are a cornerstone of innovation, user freedom, & the right to repair.


==The broader pattern==
The legal landscape has evolved dramatically through decisions like '''Google v. Oracle''' (2021) affirming API reimplementation as fair use,<ref>{{Cite web |title=GOOGLE LLC v. ORACLE AMERICA, INC.
CERTIORARI TO THE UNITED STATES COURT OF APPEALS FOR
THE FEDERAL CIRCUIT
No. 18–956. Argued October 7, 2020—Decided April 5, 2021 |url=https://www.supremecourt.gov/opinions/20pdf/18-956_d18f.pdf}}</ref>.


Futurehome's tactics represent a widespread industry pattern of using technical restrictions and legal threats to maintain control over consumer devices.
The October 2024 DMCA exemptions represent the largest repair rights texpansion so far. Combined  with Van Buren's limitation of CFAA liability, these create lots of legal   space for legit reverse engineering to be considered legal.


===Subscription conversion schemes===
Many technology companies have adopted similar strategies:
*'''Smart home devices''' that lose functionality without cloud subscriptions
*'''Automotive systems''' that require ongoing payments for features built into the hardware
*'''Medical devices''' that become unusable without service agreements
*'''Gaming hardware''' that is "bricked" when online services are discontinued
===Legal intimidation===
Companies routinely threaten consumers and researchers with DMCA 1201 violations for activities that should be protected under ownership rights:
*Analyzing firmware to understand device operation
*Creating tools to enable local device control
*Developing alternatives

Revision as of 05:22, 23 July 2025

This addresses the widespread & harmful misconception that breaking a digital lock or modifying software behavior is always "illegal hacking." In truth, U.S. law - while flawed - draws a clear line between lawful reverse engineering & criminal activity. Companies often exploit this confusion to suppress ownership rights, discourage repair, and shut down interoperability under the guise of protecting security or intellectual property.


This article seeks to clarify legal distinctions, correct the record, & explain why reverse engineering your own device to restore or preserve its functionality is not a crime.

What section 1201 is for

Section 1201 of the Digital Millennium Copyright Act (DMCA), passed in 1998, prohibits the circumvention of "technological protection measures" (TPMs) used to control access to copyrighted works. It also prohibits the distribution of tools designed primarily for circumvention.

What makes Section 1201 controversial is that it penalizes circumvention regardless of whether any copyright infringement occurred. In other words, even if you just want to modify or fix a product you legally own, you may still be in violation if the manufacturer wrapped it in DRM.

To soften this, Congress allowed for temporary exemptions reviewed every three years by the Library of Congress. These exemptions currently include certain cases of repair, diagnosis, security research, accessibility, & jailbreaking of phones. However, the process is burdensome, narrow, & inconsistently applied.

Legal Reverse Engineering vs. Illegal Hacking

Contrary to what some CEOs & PR departments have said, reverse engineering is legal in many contexts - especially when done for purposes of interoperability, repair, research, or personal use.

What Counts as Legal Reverse Engineering

The U.S. legal system has repeatedly upheld the right to reverse engineer in certain contexts, particularly when the intent is to enable interoperability or understand how something works. Notable court decisions include:

  • Sega Enterprises Ltd. v. Accolade, Inc. (1992): The Ninth Circuit ruled that disassembling code to understand how to make compatible software was fair use.[1]
  • Sony Computer Entertainment v. Connectix Corp. (2000): The court affirmed that reverse engineering to create a competing product (a PlayStation emulator) was legal & transformative.[2]
  • Lexmark Int'l v. Static Control Components (2004): The Sixth Circuit ruled that Static Control could reverse engineer printer firmware to enable third-party toner cartridges. The court pointed out that interoperability trumped DMCA anti-circumvention claims.[3]
  • Chamberlain Group v. Skylink Technologies (2004): The Federal Circuit held that creating universal garage door remotes through reverse engineering was legitimate, establishing that DMCA violations must connect to actual copyright infringement.[4]
  • DSC Communications v. DGI Technologies (1995): Courts held that disassembling firmware to create compatible microprocessor cards constituted fair use, establishing that functional elements accessed only through disassembly can be lawfully copied.[5]
  • Assessment Technologies v. WIREdata (2003): The Seventh Circuit ruled that reverse engineering to access public domain data trapped within copyrighted software is permissible, preventing copyright from creating "locks" on non-copyrightable information.[6]

Legal reverse engineering generally includes:

  • Analyzing software you own for repair or maintenance
  • Studying protocols to make devices work with third-party tools
  • Extracting firmware from your own hardware
  • Building alternate apps that communicate with your devices
  • Publishing technical findings that don't contain copyrighted code
  • Good faith security research under DMCA exemptions

What Constitutes Illegal Hacking

Illegal hacking, by contrast, involves:

  • Accessing remote systems without authorization
  • Bypassing login or authentication mechanisms on someone else's network
  • Stealing or distributing copyrighted code without a license
  • Tampering with systems in ways that compromise others' data or services
  • Continuing access after explicit revocation (see Facebook v. Power Ventures, 2016)[7]

The key difference is ownership & scope: Reverse engineering stays within the boundary of what you own. Hacking crosses into systems that you don't.

Current DMCA Exemptions (2024-2027)

The Library of Congress granted sweeping new exemptions in October 2024 that greatly expand repair rights:[8]

  • Vehicle telematics data access: Owners can now circumvent software locks to access, store, & share their vehicle's operations & diagnostic data.
  • Commercial food preparation equipment: New exemption for retail-level restaurant equipment repair (addressing the McDonald's ice cream machine problem)[9]
  • Consumer devices: Renewed exemptions for smartphones, tablets, smart TVs, & IoT devices
  • Medical devices: Continued exemption with FDA support, concluding it wouldn't "necessarily & materially jeopardize" device safety[10]
  • Jailbreaking: Expanded to cover smartphones, smart TVs, voice assistants, & routers for installing alternative software

These exemptions require that circumvention be a "necessary step" for the permitted purpose & cannot facilitate access to other copyrighted works.

Narrowing Computer Hacking Laws

The Supreme Court's 2021 decision in Van Buren v. United States fundamentally changed how courts interpret the Computer Fraud & Abuse Act (CFAA).[11] The 6-3 majority adopted a "gates-up-or-down" test: you either have permission to access a computer system or you don't. Violating terms of service or using legitimately accessed data for improper purposes doesn't constitute "exceeding authorized access" under CFAA.

This decision protects security researchers & reverse engineers who:

  • Access publicly available systems
  • Use credentials they were legitimately given
  • Don't bypass technical access controls
  • Violate only terms of service, not technical barriers

The Ninth Circuit applied this framework in hiQ Labs v. LinkedIn (2022), finding that scraping publicly accessible data doesn't violate CFAA since there are "no gates to lift or lower" on public websites.[12]

Futurehome example:

In May 2025, Norwegian smart home company Futurehome was acquired out of bankruptcy. The new owners, FHSD Connect AS, introduced a mandatory subscription model: customers had to pay an annual fee of 1,188 NOK (approx. $117 USD) or lose access to basic functionality like the mobile app, automation, & local APIs - even though those features were previously included in the one-time purchase price.[13]

When customers began exploring ways to restore lost functionality through reverse engineering, Futurehome CEO Øyvind Fries accused them of "illegal hacking" & threatened legal action.[14]

However, no evidence was provided that users were:

  • Accessing Futurehome's servers without authorization
  • Distributing proprietary code
  • Compromising the privacy of others

Consumer rights advocate Louis Rossmann offered a $5,000 bounty for someone to create a way to use Futurehome devices locally without a subscription. His viewers began:

  • Capturing network traffic from their own devices
  • Analyzing firmware dumps from hubs they physically owned
  • Attempting to restore functionality that had been removed post-sale

The purpose was to restore functionality customers had already paid for. Futurehome's management tried to frame this as a bounty for criminal activity.

Other Examples with Legal Clarity

  • John Deere Tractors: Deere has long fought independent repair efforts, but under pressure from state laws & exemptions granted by the Library of Congress, some tractor repair activities (such as accessing diagnostic software) are now explicitly legal.[15] The FTC & state attorneys general sued John Deere in January 2025 for monopolizing agricultural equipment repair.[16]
  • Sony PlayStation 3 jailbreaking: Sony sued George Hotz (Geohot) after he jailbroke a PS3. While Sony sued him civilly, the case settled without establishing that his actions were criminal.[17]
  • Lexmark Printers: As mentioned above, the Sixth Circuit ruled that making third-party toner cartridges work with Lexmark printers - despite digital locks - was not illegal.[3]
  • United States v. Elcom/Sklyarov (2001-2002): Though Russian programmer Dmitry Sklyarov was arrested for creating Adobe eBook circumvention software, charges were dropped against him personally & his company ElcomSoft was acquitted, demonstrating prosecutorial overreach risks.[18]

"Illegal Hacking" as a legal conclusion

Using words like "hacking" to describe legitimate reverse engineering is not a legal conclusion. Section 1201 of is written in a way that can make even normal ownership behavior sound suspicious. Courts have repeatedly ruled that reverse engineering, when done for lawful purposes, is protected.

Key Legal Principles

Courts now apply clear principles distinguishing lawful reverse engineering from illegal hacking:

Protected Activities Include:

  • Lawfully acquiring software or hardware
  • Analyzing it without circumventing authentication
  • Conducting interoperability research under DMCA Section 1201(f)
  • Accessing publicly available information
  • Good faith security research with responsible disclosure

Risk Factors for CFAA/DMCA Liability:

  • Bypassing passwords or authentication systems
  • Continuing access after explicit revocation
  • Accessing non-public systems
  • Causing system damage
  • Commercial exploitation of circumvention tools

The distinction often turns on technical circumvention - courts protect analytical activities that don't breach access controls while penalizing those who bypass passwords, authentication, or security measures.

Conclusion

Reverse engineering is not a crime. Owning a product should mean controlling it. & efforts to restore, understand, or interoperate with devices you legally bought are not "hacking" - they are a cornerstone of innovation, user freedom, & the right to repair.

The legal landscape has evolved dramatically through decisions like Google v. Oracle (2021) affirming API reimplementation as fair use,[19].

The October 2024 DMCA exemptions represent the largest repair rights texpansion so far. Combined with Van Buren's limitation of CFAA liability, these create lots of legal space for legit reverse engineering to be considered legal.
