Bitcoin ATM maker Lamassu Industries has successfully addressed a vulnerability that could have granted hackers “full control” over its Bitcoin ATM machines. The flaw was discovered by a team of ethical hackers from the security firm IOActive during an attempted compromise of Lamassu’s Bitcoin ATMs in 2023. The researchers documented the vulnerabilities they discovered, which allowed them to gain full control over the ATMs.

Exploiting the Vulnerability

Here is a video that demonstrates how IOActive’s researchers exploited the vulnerability:

According to Gunter Ollman, CTO of IOActive, attackers who exploited this vulnerability could “view and manipulate interactions with the hijacked ATM.” This means that hackers had the potential to steal Bitcoin from users’ wallets by taking advantage of the identified vulnerabilities. Ollman warned that a sophisticated attacker could even modify the entire user experience, tricking users into entering their bank account details.

While Ollman assured the community that the attack’s impact would be limited to a user’s account balance, the potential for social engineering was significant.

Attaining “Full Control”

Gabriel Gonzalez, Director of Hardware Security at IOActive, stated that the vulnerability could grant an attacker “full control” over a physical ATM machine. This level of control would enable them to drain all the money in the ATM and manipulate the note reader to display inaccurate deposit amounts. The severity of these vulnerabilities is particularly concerning if the ATMs are left unattended in various locations.

Prompt Response and Patch Deployment

Thankfully, Lamassu Industries took prompt action upon discovering these vulnerabilities. They deployed a security patch to fix the vulnerabilities before publicly disclosing them in 2024. Lamassu also advised owners of their Bitcoin ATMs to update their software to ensure their machines were secure.

The Decline of Bitcoin ATMs

In a separate report, it was revealed that the number of installed Bitcoin ATMs worldwide had declined in 2023 after consistently increasing for over a decade. This decline was primarily attributed to a noticeable decrease in the number of machines in the US from 2022 to 2023, while other regions saw an increase in installations.

According to Coin ATM Radar, the US accounts for 82% of all installed Bitcoin ATMs globally, with 27,621 machines in operation as of the end of last year.
