Brief Description 

    

Sysbug.A is a Trojan type password stealer that has been massively sent in an e-mail message with the subject Re[2]:Mary and an attachment called PRIVATE.ZIP. The attached file is compressed with a ZIP format, and contains a file with a double extension called WENDYNAKED.JPG.EXE.

Sysbug.A tries to steal confidential data, such as passwords belonging to accounts, mail servers (SMTP and POP3), newsgroups, Dial-up and networking accounts, etc. It will then log this information in a file that will be sent to a hacker.

In addition, Sysbug.A has backdoor characteristics, as it opens the TCP port 5555 and waits for control commands to carry out.

Visible Symptoms 

    

Sysbug.A is easy to recognize, as it reaches the computer in an e-mail message that has been massively sent and has the subject Re[2]:Mary and an attachment called PRIVATE.ZIP.
