Kapersky has revealed that the Live Update Utility tool provided by ASUS has been hacked and that users who have downloaded the software could be exposed to harmful malware.
The attack, which has been called Operation Shadowhammer, was designed to target a specific pool of users that were identified by their network adapters’ MAC addresses.
You can enter your device's MAC address into this tool built by Kaspersky to find out if your device was targeted.
This particular type of attack is known as a ‘supply chain’ attack. The hackers apparently broke into ASUS’s own update servers and replaced the valid software with an infected version. This version appeared identical to the legitimate software and because of this was left on the ASUS servers undiscovered ‘for a long time’.
On the bright side, if you’re not one of the very few people specifically targeted by this attack, you probably don’t have much to worry about. The attack was targeted at a list of people that had something specific that the nefarious party was looking for, so if you’re just an average consumer who uses their ASUS computer to shop online, look at cat pictures and play games, you almost certainly don’t have anything to worry about.
Kaspersky notified ASUS of the attack on 31 January this year, while also mentioning that during its investigation it found the same techniques were used against software from three other vendors too, although it wasn’t specific as to which companies this might be.
