Remove Trojan.Vundo and Terminate is154522.exe, Install.exe

According to security research, the infamous Vundo malware may be active again. Two executable processes have been recently monitored to contain the malicious piece – is154522.exe (reported by HerdProtect) and Install.exe (reported by VirusTotal). Trojan.Vundo, also known as VirtuMonde, VirtuMundo, and MS Juan, is classified as a Trojan horse that downloads files and generates pop-up advertisements. The malware is typically spread through spam email campaigns. Other distribution methods are also not surprising – p2p file sharing and drive-by downloads. Trojan.Vundo may also be dropped by other malware, such as Trojan downloaders and Trojan droppers.

Trojan.Vundo Technical Resume

Trojan.Vundo has been monitored to drop malicious executables on targeted systems. The names of the files can be bland (such as install.exe), so that the users are tricked into opening and running them.

However, Vundo can be dropped by other malicious software, predominantly by worms. Two mass-mailing worms have been reported to spread the Trojan:

• W32.Ackantta.B@mm
• W32.Ackantta.C@mm

Researchers have concluded that Trojan.Vundo was created for the purpose of displaying advertisements – such as pop-ups. The Trojan can also inject ads into the victim’s search results.

The pop-ups displayed by Trojan.Vundo can be:

• Fake scan alerts made to look like legitimate AV software.
• System errors.
• Pop-ups prompting users to download rogue applications.
• Adult-themed ads and services.

Clicking on the pop-ups generated by Trojan.Vundol will redirect the user to malicious websites. In addition, once the threat is activated, the user can experience difficult accessing certain pages or running an anti-virus program.

WARNING

is154522.exe and Install.exe are the two most recent files, associated directly with Trojan.Mundo.

According to researchers at Symantec, latest Trojan.Vundo types have become more sophisticated with time. Some of them may even include rootkit capabilities or can exploit local vulnerabilities. Moreover, Trojan.Vundo can even have file-encrypting skills and act as ransomware, extorting money from the victim, etc.

Here is a list of heuristic detections of Trojan.Vundo:

→Suspicious.Vundo, Suspicious.Vundo.2, Suspicious.Vundo.5, Packed.Generic.295, Packed.Generic.254, Packed.Generic.324, Packed.Vuntid!gen1, Packed.Vuntid!gen2, Trojan.Vundo.B!inf, Trojan.Vundo!gen1, Trojan.Vundo!gen2, Trojan.Vundo!gen3, Trojan.Vundo!gen5, Trojan.Vundo!gen7, Trojan.Vundo!gen8

Here is a list of detection names by various AV providers:

• DR/Virtumonde.tmj.40 (Avira Antivirus)
• Win32:Akan (Avast)
• MemScan:Trojan.FakeAlert.AJF (BitDefender)
• Trojan.DownLoader.50219 (Dr.Web)
