Arrival Details

This Ransomware arrives on a system as a file dropped by other malware or as a file downloaded unknowingly by users when visiting malicious sites.

Installation

This Ransomware drops the following files:

  • %Public%\pwndll.dll ← Detected as Trojan.Win64.AGENDA.SVT
  • %Public%\netuse(GUID).log ← mapped network drives
  • %Public%\SuccessPreload.{GUID}.log ← computer name and user name
  • %Public%\working.log ← injected services
  • %Public%\{Process ID}.log ← program logs
  • %Public%\shares.log ← attached network resources

(Note: %Public% is the folder that serves as a repository of files or folders common to all users, which is usually C:\Users\Public in Windows Vista, 7, and 8.)

It drops the following copies of itself into the affected system:

  • %Public%\enc.exe

(Note: %Public% is the folder that serves as a repository of files or folders common to all users, which is usually C:\Users\Public in Windows Vista, 7, and 8.)

It adds the following processes:

  • %System%\cmd.exe /c vssadmin.exe delete shadows /all /quiet
  • powershell -Command \"{get-service LanmanWorkstation |Restart-Service -Force}\"
  • %System%\net.exe net use

(Note: %System% is the Windows system folder, where it usually is C:\Windows\System32 on all Windows operating system versions.)

It injects its dropped file/component to the following processes:

  • %Public%\pwndll.dll → injected to svchost.exe

(Note: %Public% is the folder that serves as a repository of files or folders common to all users, which is usually C:\Users\Public in Windows Vista, 7, and 8.)
