About This Screamer
Maker	FlashUpload
Type	Application
Release date	2009

Blackcom is a screamer trojan created by FlashUpload. It was written in VBScript.

When launched, it displays a false MSWORD.exe error message that reads:

Microsoft Word cannnot open this document because it contains characters MSWORD.EXE does not understant

After a couple seconds, it displays a false binary error message that reads:

Microsoft Word Cannot Complete The Operation Requested Due To Security Risks 

Please include the following in your error report 

01011011 01101111 01110101 00100000 01000111 00100000 01110100 00100000 01100101 00100000 00100000 00100000
01011011 01101111 01110101 00100000 01000111 00100000 01110100 00100000 01100101 00100000 00100000 00100000

This message is then followed by Microsoft Sam saying: "CAUTION! A virus has been detected."

Blackcom then displays more bogus fake error messages about svchost.exe and DRVSTORE, then displays a message stating:

An important system file is not found and WINDOWs can no longer run. 

After several seconds pass, the trojan initiates a system shutdown and corrupts hal.dll in the System32 directory, rendering Windows unbootable. Furthermore. Blackcom will change the homepage to a YouTube screamer, but it is unclear what the screamer was.

Showcases

NOTE: Although this trojan contains a screamer, it is not visible in these showcases.
