⬥EPISODE NOTES⬥
What if the device quietly recording your daily commute could be turned against you in the time it takes to order a burger? That is not a hypothetical -- it is a demonstrated reality. Alina Tan, Security Architect and Co-Founder of HE&T Security Labs, and George Chen, Security Architect for a large global company, have spent years dissecting the attack surface of connected vehicle peripherals. Their research -- presented at SecTor and Black Hat Asia 2025 -- introduces a novel attack technique they call "DriveThru Hacking": an automated method for compromising dashcams through Wi-Fi within a standard drive-through window.
The attack is unsettling in its simplicity. Most dashcams ship with default or easily guessable credentials, and many manufacturers do not even allow users to change them. Within a six-minute exposure window, Alina and George's tool -- DriveThru Hacker -- can discover, connect to, and exfiltrate video, audio, and GPS data from a target dashcam, then use an LLM to stitch together a timeline of the owner's home, workplace, daily routes, and private conversations. The result is a shockingly detailed picture of someone's life, assembled entirely from a device most people never think to secure.
The research goes further than individual privacy. George walks through how 4G/5G-connected dashcams dramatically expand the attack surface beyond physical proximity -- opening doors to remote credential stuffing, API privilege escalation, and web-based attacks on cloud-connected accounts. More alarming still, Alina and George demonstrate how compromised dashcams can be converted into a mobile botnet -- a network of roaming, internet-connected nodes whose reach is not bounded by geography. Unlike static IoT devices, these infected cameras move through cities, near sensitive installations, and into places that are deliberately obscured from public maps.
The conversation also digs into the broader ecosystem: the infotainment network and CAN bus segmentation (or lack thereof), over-the-air firmware update security, the challenge of detection and response when dashcams have no audit logs whatsoever, and what responsible disclosure looked like when contacting over a dozen manufacturers -- most of whom had no dedicated security inbox and some of whom had no contact information at all. Alina and George close with practical hardening recommendations for both consumers and manufacturers, and a look at what intrusion prevention for embedded devices might look like as this research continues.
The connected car conversation has long focused on the vehicle itself. This episode makes the case that the accessories attached to it deserve equal scrutiny -- and that the window to act, like the drive-through line, is shorter than most realize.
