Windows and Linux users need to beware, as an all-in-one, destructive malware strain has been discovered in the wild that features multiple malware capabilities including ransomware, cryptocurrency miner, botnet, and self-propagating worm targeting Linux and Windows systems.
Dubbed XBash, the new malware, believed to be tied to the Iron Group, a.k.a. Rocke—the Chinese speaking APT threat actors group known for previous cyber attacks involving ransomware and cryptocurrency miners.
According to the researchers from security vendor Palo Alto Networks, who uncovered the malware, XBash is an all-in-one malware that features ransomware and cryptocurrency mining capabilities, as well as worm-like ability similar to WannaCry or Petya/NotPetya.
In addition to self-propagating capabilities, XBash also contains a functionality, which is not yet implemented, that could allow the malware to spread quickly within an organization’s network.
Developed in Python, XBash hunts for vulnerable or unprotected web services and deletes databases such as MySQL, PostgreSQL, and MongoDB running on Linux servers, as part of its ransomware capabilities.
Once find an open port, the malware uses a weak username and password dictionary attack to brute force itself into the vulnerable service, and once in, deletes all the databases and then displays the ransom note.
What’s worrisome is that the malware itself does not contain any functionality that would allow the recovery of the deleted databases once a ransom amount has been paid by the victims.
To date, XBash has infected at least 48 victims, who have already paid the ransom, making about $6,000 to date for cybercriminals behind the threat. However, researchers see no evidence that the paid payments have resulted in the recovery of data for the victims.
The malware also has capabilities to add targeted Linux-based systems in a botnet.
