GEMA Virus

Post by sniper3d »

Automatically translated from French.

A new variant of ransomware after the Gendarmerie Virus: GEMA - Access to your computer has been closed GEMA is the equivalent of SACEM in Germany, so it's a ransomware that has been translated, since it already existed in a German version:https://www.malekal.com/2011/11/30/troj ... us-police/

The purpose here is therefore to make internet users believe they have been caught downloading songs illegally (piracy), hence the message: On your computer, there are songs that were downloaded illegally

Image unavailable (removed by its host) This latter drops a file C:/Windows/System32/InetAccelerator.exe
Of course the name will change over time with variants.

A Run key is created as well as modification of the Winlogon key. This means that the malware will be active in safe mode including the command prompt in safe mode.

Disinfection

Windows Seven: System Restore

Only for those on Windows Seven: Launch a restore at startup via the F8 key, for more information, see the repair tab: https://forum.malekal.com/windows-recuper...ml#p166847

From a Live CD

You can try disinfection via Kaspersky Live CD: https://forum.malekal.com/kaspersky-live-...12133.html
If the latter detects the malware and cleans it at restart, you will be able to recover the system.
Kaspersky Live CD can be put on a USB key: https://support.kaspersky.com/faq/?qid=208285003

Boot on an alternative system (Live Linux CD) or OTLPE: https://forum.malekal.com/otlpe-live-t2 ... ml#p195540
This allows you to access the PC files.
Go to the system32 folder and sort the files by modification date, you should have the latest created files first and thus the malware.
If in doubt, do a scan on VirusTotal: https://www.virustotal.com
Rename the file in question
Restart the computer and see if the latter is inactive.

Note that you can also access the file system over the network if the PC is booted on the malware window.
From a PC on the network, in the taskbar, type: PCAddressc$WindowsSystem32
Same thing, sort the files by modification date to find the malware in question.

Right now the german police virus is up to its tricks, but well, tdskiller, rogue killer, malwarebytes and combofix make it regret ever coming to your pc.
