Dashcams have develop into important units for drivers worldwide, serving as dependable witnesses in case of accidents or roadside disputes.
Nevertheless, a crew of Singaporean cybersecurity researchers has uncovered a disturbing actuality: these seemingly innocent units could be hijacked inside seconds and become highly effective surveillance instruments.
The findings, introduced on the Safety Analyst Summit 2025, reveal how attackers can bypass authentication mechanisms to entry high-resolution video footage, audio recordings, and exact GPS knowledge saved on these units.
The analysis examined two dozen dashcam fashions from roughly 15 totally different manufacturers, beginning with the favored Thinkware dashcam.
Most dashcams, even these with out mobile connectivity, characteristic built-in Wi-Fi that enables smartphone pairing by cell apps.
This connectivity creates a big assault floor that malicious actors can exploit to obtain saved knowledge remotely.
Kaspersky safety researchers recognized that many dashcam fashions use hardcoded default passwords and related {hardware} architectures, making them weak to mass exploitation.
As soon as linked, attackers acquire entry to an ARM processor working a light-weight Linux construct, opening doorways to varied confirmed exploitation methods generally seen in IoT machine assaults.
Authentication Bypass Methods
The researchers found a number of strategies attackers use to bypass producer authentication. Direct file entry permits hackers to request video downloads with out password verification, as the net server solely checks credentials on the most important entry level.
MAC handle spoofing permits attackers to intercept and replicate the proprietor’s smartphone identifier, whereas replay assaults contain recording official Wi-Fi exchanges for later exploitation.
Maybe most regarding is the worm-like propagation functionality the researchers developed.
They wrote code that operates straight on contaminated dashcams, permitting compromised units to robotically assault close by dashcams whereas autos journey at related speeds in visitors.
A single malicious payload designed to aim a number of passwords and assault strategies may efficiently compromise roughly 1 / 4 of all dashcams in an city setting.
The harvested knowledge permits full motion monitoring, dialog monitoring, and passenger identification.
Utilizing GPS metadata extraction, textual content recognition from highway indicators, and OpenAI fashions for audio transcription, attackers can generate detailed journey summaries, successfully de-anonymizing victims by analyzed behavioral patterns.
Drivers ought to disable Wi-Fi when not in use, change default passwords, and usually replace firmware to mitigate these dangers.
