JS/Column.EB.1 is a JavaScript Trojan that is included in a spam malware campaign related to Craigslist and eFax Corporate. JS/Column.EB.18 spreads via bogus eFax Corporate and Craigslist emails. Cybercrooks are using a combination of social engineering techniques to dupe affected PC users into opening emails that carry malware, specifically JS/Column.EB.18. The spam emails supposedly come from Craigslist that are sent via eFax Corporate. The unsolicited email messages, which are not associated with either Craigslist or eFax, notify recipients that they've received a fax of 24 pages. However, the attachment of the fake Craigslist or eFax email messages is not a fax, but an .HTML file which includes a malicious JavaScript code. Once executed, the script downloads a malware threat, detected as JS/Column.EB.18, onto the victimized computer system.
