The first spam leads to a hacked site in Australia (there are probably many others). In turn, this tries to load four scripts to install malware though an HCP attack (Wepawet report here). The scripts are:


In all cases, those scripts appear to be on legitimate (but hacked) websites. The final step for that attack is to try to install a malicious Java application from colobird.com/content/import.jar - a domain that is hosted on but one that was only registered very recently.

The second and third emails take a different approach, loading a page at www.btredret.ru/main.php hosted on (S.C. Profisol Telecom S.R.L., Romania). This attemps a Java exploit (Wepawet report here). This IP is part of a small netblock of - ( and can probably safely be blocked, or you could just block the whole /24 if you wanted,

This is an old approach that has been doing the rounds for two years. It must still work though..
