Iranian state-sponsored hackers have deployed a new strain of data-wiping malware on the network of Bahrain’s national oil company. The security incident came to light amid rising political tensions between the US and Iran after the US military killed a top Iranian military general in a drone strike last week.
Dustman is a so-called data wiper — malware designed to delete data on infected computers, once launched into execution. The main shared component between all three strains is EldoS RawDisk, a legitimate software toolkit for interacting with files, disks, and partitions. The three malware strains use different exploits and techniques to elevate initial access to admin-level, from where they unpack and launch the EldoS RawDisk utility to wipe data on infected hosts.
Since Dustman is considered an evolved version of ZeroCleare, most of the code is the same, but Saudi CNA officials who analyzed the malware said Dustman comes with two important differences:
Successful attacks resulted in all wiped systems showing a Blue Screen of Death (BSOD) message.
