How Two Researchers Exposed a Massive IoT Security Blind Spot
At February 2025’s DistrictCon Junkyard competition, cybersecurity researchers Alan Cao and Will Tan from Trail of Bits shook the industry with a demonstration that sent shockwaves through the home security world. They successfully hacked two discontinued but once-popular home security devices — the Netgear WGR614v9 router and the BitDefender Box V1 — revealing deep-rooted vulnerabilities that remain exploitable long after official product support ends. Their feat earned them the runner-up spot at the event, but more importantly, it spotlighted a disturbing reality: outdated and abandoned devices continue to pose massive risks in the digital age.
These devices, originally marketed as safeguards for home networks, have now transformed into high-risk vulnerabilities, or “zombie tech,” lurking in millions of households. Cao and Tan’s detailed attack strategy involved complete remote control via local network access, exploiting flaws that will never be patched due to the devices’ discontinued status. Their work raises urgent questions about the technology sector’s commitment to lifecycle security and the widespread neglect of older, unsupported hardware. Even worse, the researchers proved how easily attackers could weaponize long-known vulnerabilities — some patched in newer models — simply by downgrading device firmware.
Their findings are now publicly available, setting the stage for greater awareness and potential policy reform. But the underlying message is loud and clear: legacy hardware isn’t just outdated, it’s a ticking time bomb. With the second Junkyard competition slated for 2026, more discoveries like this are likely on the horizon.
Abandoned Devices, Active Threats: What Hackers Exploited and Why It Matters
The Targets: Discontinued Yet Dangerous
Cao and Tan chose two popular but unsupported consumer-grade security devices: the Netgear WGR614v9 router and the BitDefender Box V1. Both were discontinued years ago, and both had served as key points of protection in many home networks. But once manufacturers dropped support, they became ideal targets — still deployed in homes, no longer patched, and easily exploitable.
Netgear Router: Exploiting UPnP for Root Access
The Netgear router was breached using three separate attack vectors, each focusing on its Universal Plug and Play (UPnP) services. These flaws included:
Authentication bypass
Buffer overflow vulnerabilities
Command injection opportunities
One particularly inventive technique, called bashsledding, modified traditional nopsled approaches by using shell commands instead of processor instructions to gain execution flow. This method showcased how outdated code paths remain deeply vulnerable to reinterpretation and abuse.
BitDefender Box: Downgrading Security to Break It
The BitDefender Box V1, ironically marketed as a cybersecurity solution, contained even more worrying vulnerabilities. The researchers exploited:
Firmware downgrade loopholes
Command injection flaws in validation routines
By rolling back the firmware to an earlier, less secure version, they unlocked access to vulnerabilities that were long-since patched — a catastrophic oversight for any device meant to provide protection.
What Undercode Say:
A Systemic Failure in Lifecycle Security
Trail of Bits’ findings paint a grim picture of how the tech industry treats discontinued products. Once a device reaches its “end-of-life” (EOL) status, manufacturers wash their hands of responsibility. But these devices don’t disappear — they remain plugged into networks worldwide, creating static, persistent vulnerabilities.
This practice leads to the rise of what researchers call “fossil flaws” — ancient bugs left wide open for attackers to rediscover. Unlike zero-days, which are novel and unknown, these are immortal vulnerabilities that never get fixed, yet stay just as dangerous.
The Bigger Issue: IoT’s Insecure Foundation
The root cause isn’t just one company or one device. It’s a systemic flaw in IoT device architecture:
Poor UPnP design is endemic across routers and home hubs.
Firmware validation routines are often weak or missing.
Lack of long-term update commitments means devices lose their security posture far too early.
Manufacturers prioritize profit over protection. Devices are shipped, sold, supported briefly, and then forgotten. Meanwhile, users assume the devices are still safe because they “just work.”
Open Source Firmware: A Glimmer of Hope
One promising solution is adopting open-source firmware like OpenWRT or DD-WRT for routers. These community-supported platforms offer continued patching, even after manufacturers abandon devices. While not a universal fix, they represent an empowering option for tech-savvy users willing to take control.
Junkyard Competitions: Ethical Hacking With a Purpose
Events like DistrictCon’s Junkyard bring ethical hacking into the spotlight. By encouraging responsible disclosure and creative exploitation of abandoned tech, they raise awareness about the growing junkyard of insecure digital infrastructure.
Moreover, they offer a crucial training ground for researchers to test skills and shine a light on the darker corners of cybersecurity. This dual benefit — community education and systemic pressure — makes them essential in modern threat analysis.
Regulatory Oversight May Be Needed
Without external accountability, many companies have no incentive to extend the security lifecycle of their products. Governments and watchdog organizations may need to introduce regulations requiring minimum support windows, or at least transparency in EOL declarations.
Such moves could push manufacturers to take responsibility for the long-term safety of their users, especially for devices connected to critical home networks.
🔍 Fact Checker Results:
✅ Confirmed: Both Netgear WGR614v9 and BitDefender Box V1 are officially discontinued.
✅ Verified: Trail of Bits published working exploits and technical breakdowns.
✅ Accurate: Bashsledding is a new variant of shell-based exploitation described by the researchers.
📊 Prediction:
Expect a wave of legacy hardware exploitation revelations as cybersecurity researchers target more discontinued devices in upcoming competitions.
💥 Users with older routers or IoT devices will increasingly face real-world threats unless manufacturers adopt longer-term patch policies.
🔐 Demand for open-source and community-supported firmware will rise, becoming a new battleground for both protection and attack innovation.
