These spam emails are disguised as notifications from Craigslist. In the email if the victim clicks on the link “Click here”, it will lead to the following address:
Like most malicious emails, if the user clicks the link the browser will redirect to a page that hosts an exploit such as BlackHole Exploit Kit and will only display text like “Please wait” as shown below:
The exploit script will make several requests to some addresses on this domain: paranoiknepjet.ru. If the machine has been successfully exploited it will eventually download and execute the malware file.
Here is a string found during our research, which includes some online banking site addresses obtained after the malware makes requests to the C&C server:
Emsisoft Anti-Malware (EAM) detects the trojan file as variant of Cridex (Trojan.Win32.Cridex).

Most of the malware uses exploits like the BlackHole Exploit Kit or PDF Exploit, which targets computers with unpatched vulnerabilities. In other words, the operating system or software installed on your computer such as Adobe Flash, Adobe Reader, and Java is not updated or patched.
We strongly recommend always updating the operating system and the software you use to reduce the risk of malware infections.
