Virus.Win32.Gpcode.ak
by Marianna Schmudlach / June 5, 2008 4:19 AM PDT

Kaspersky Lab has detected a new version of the ?malicious blackmailer? Gpcode ? Virus.Win32.Gpcode.ak.

The new Gpcode variant encrypts files with extensions DOC, TXT, PDF, XLS, JPG, PNG, CPP, H etc. on hard drives using an RSA algorithm with a 1024-bit key.

After encrypting files, the virus leaves a text file in the folder next to the encrypted files with following message:


Your files are encrypted with RSA-1024 algorithm.
To recovery your files you need to buy our decryptor.
To buy decrypting tool contact us at: ********@yahoo.com
Currently, we detect the new variant, but we are unable to crack the 1024-bit key. Our analysts are continuing to work on both the key and the virus to resolve this issue.

WORM_SOHANAD.CO
by Marianna Schmudlach / June 5, 2008 4:42 AM PDT

Ticking Time Bombs in Forum File Uploads

On 02 June 2008 7:26 PM PST, one of our analysts came across a malware detection for a file found inside a regionally popular legitimate site. A legitimate site will never host malware on purpose, so it seemed but proper to dig deeper into the story.

It appears that instead of setting up some highly sophisticated SQL or XSS attack, which has been all the fare last May, the malicious user took a much more barefaced (and simpler) route: he/she uploaded the file via the site?s restricted access forum file upload feature.

The file is detected by our scanners as WORM_SOHANAD.CO (since 03 September 2007). It spreads via instant messaging applications and via removable drives. It disables Task Manager, executes at each system startup, and drops copies of itself on the infected PC.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
