Bringing Malware to a new level - SpamThru Trojan Analysis
 

Understanding the purpose of malware simply by searching anti-virus writeups can sometimes be a daunting task. Often, we see trojans which have painfully little information about their functionality other than "backdoor", or "keylogger", or "proxy". In many cases, widely varying trojans are given similar, non-descriptive names like "Trojan.Agent.abc", further adding to the murky view we have of just what modern malware is up to.


Sometimes, when we shine a light on a particular piece of malware, we find some interesting things that would otherwise go unnoticed. One such piece of malware is the trojan sometimes called "Troj/SpamThru", among other names.
