If you are one of the folks that likes to install the crap that ASUS provides with your motherboard you might just have a nasty backdoor installing malware. According to Kaspersky Labs, via Motherboard, the ASUS servers were hacked last year and the hackers used it to install malware using the software update utility. This could have resulted in as many as a million computers being infected. Consider this a PSA. Kaspersky Lab said it uncovered the attack in January after adding a new supply-chain detection technology to its scanning tool to catch anomalous code fragments hidden in legitimate code or catch code that is hijacking normal operations on a machine. The company plans to release a full technical paper and presentation about the ASUS attack, which it has dubbed ShadowHammer, next month at its Security Analyst Summit in Singapore.
