Hong Kong - Animated heart-shaped cards aimed at healing restless hearts are common during the Valentine season. However, according to the latest blog post by Bhaskar Krishnappa, Malware Analyst, Symantec Hosted Services, hidden malware is exploiting this holiday, causing pain to both users and security vendors alike.
Krishnappa describes one attack that, when analysed, was found to contain a component called ScriptCryptor (http://www.abyssmedia.com/scriptcryptor/). Despite the fact that the ScriptCryptor tool is designed to build legitimate applications, it being misused by malware authors to construct executable files using social engineering themes such as “For u, girls)))”
“It is quite handy for people aware of minimal scripting, Java or VBs knowledge. Additionally, more authors can add their arbitrary resource icon and the version information to the executable file,” he says.
The main feature of this tool is the original script that is used to generate a Delphi executable.
“It is internally encrypted using a blowfish algorithm. Most of the AV scanners that scan this file think that the file is a non-encrypted Delphi executable and trigger their signatures or generic heuristics written for the Delphi executable and declare the file as clean. But, this is a password stealer which then steals stored passwords from web-browsers,” said Krishnappa.
Krishnappa offers a chilling warning. “At the time of analysis, only five scanners out of 41 were detecting this sample.”
With Valentine-themed spam creeping towards 10% of all spam – or 10-20 billion bogus messages per day worldwide according to best estimates – this romantic celebration is likely to be a heartbreaker for many people.
However, not for customers of Symantec Hosted Services, which is already intercepting the suspect messages as part of its standard service level agreement that guarantees to detect and stop 100 per cent of all known and unknown viruses.
