It drops the following files in the Temp directory.

TeamViewer

Once the malware arrives into victim system it executes the TeamViewer[.]exe file which loads the malicious DLL file from (“%User Temp%\PmIgYzA\TV.dll”) and then it gathers following the user and device data and sends them back to hxxp://intersys32[.]com.

Following are the data collected

  • Operating System
  • OS Architecture
  • Computer Name
  • User Name
  • RAM size
  • Presence of AV Products
  • Administrator Privilege

Researchers found the malware connected to the particular URL used by another trojan CoinSteal and an information stealer malware called Fareit.

Misusing of TeamViewer is not new, recently attackers used TeamViewer to deliver powerful malware that gain the victim’s system control remotely and steal money from the target organization.

“We saw that the tool was trojanized by adding a malicious DLL to a legitimate version to be loaded onto a victim’s device.”
