USB (Universal Serial Bus) is one of the common interface used by many users for data sharing and many other purposes. One of the common application is the Pen Drive that has been used in large scale. Recently there has been a new malware that has been spreading in large scale.
Dubbed #USB Thief is now doing many malicious activities and it has been identified that they are targeted for the isolated computers that are not connected to the Internet.
It is said that to make a computer safe it should be disconnected from the Internet but this proves the fact to be false since it is attacking the isolated computers.
Few months back its #Stuxnet a program that causes a massive destruction also implanted through the USB and initiated from the computer that is isolated from the network.
#USB Thief is masked as either the portable applications plugin or any DLL (Dynamically Linked Library) files. The malwares steals the sensitive data from the system if the program has been executed.
The malware is mainly for the air-gapped systems and it uses multi-stage encryption which makes it very harder for any anti-virus program to detect them and since it is USB leaves no traces in the local computer.
Few months back there has been USB Kill that explodes the computer and now USB Thief. Users are recommended not to use any USB from untrusted source and regular backup plan will help much.
P.S: The post is to create awareness and not to be misused.
