Bitcoin ATM manufacturer, General Bytes has confirmed that its Bitcoin ATMs were compromised due to a zero-day attack on 18 August 2022.

The zero-day bug made it possible for hackers to appoint themselves as the default administrators of the Bitcoin ATMs, which allowed them to change the destination wallet addresses of the ATMs so that any funds from transactions would be transferred to their wallet. Upon discovering the attack, the company advised all operators to update the software of the machines to thwart any further attacks.

In addition, before activating the machines again, operators were advised to check the review of the “SELL crypto” settings. The company has not yet disclosed how much worth of crypto the hackers were successful in stealing.

According to the company, hackers targeted the machines through zero-day vulnerability attacks to gain access to the company’s crypto application service (CAS) and extract funds.

An advisory on the incident by the company explained: “Attacker scanned Digital Ocean cloud hosting IP address space and identified running CAS services on ports 7777 or 443. Including General Bytes Cloud service and other GB ATM operators running their servers as Digital Ocean is a recommended cloud hosting provider.”

General Byte is one of the largest manufacturers of Bitcoin ATMs, and close to 8,827 of its Bitcoin ATMs are functional in over 120 countries. In recent months, crypto exchanges and crypto ATM operators have increased their installation rate of crypto ATMs and its number has already crossed 39,000 units.
