20 Mar 2014Spam News
A lot of malicious attachments in February’s spam came in emails allegedly sent by women who wanted to make new friends in the run-up to Valentine's Day. Some attackers went even further by trying to hook recipients with the promise of explicit photos in archives attached to messages. There were also more conventional malicious mass mailings imitating fake notifications from popular social networking sites, including Facebook.
February’s love-themed malicious spam was dominated by Trojans, as the cybercriminals’ mass mailings targeted credulous users with a Trojan-Dropper. The Trojan installs two malicious programs on the system – one is spyware that steals all document files (*. Docx, *. Xlsx, *. Pdf) from the computer and sends them to a specific mailbox; another is IRC-bot/worm called ShitStorm which can carry out DDoS attacks on websites and spread copies of itself via MSN and P2P services. If recipients respond to this sort of email, their computer can easily become part of a botnet. In addition to Trojan spyware this month’s malicious spam included ransomware – a type of malware that blocks the user's computer and then demands money to unblock it. The explicit photos also turned out to be malicious programs and among them was the Andromeda backdoor that allows cybercriminals to secretly control a compromised computer.
Yet another malicious program imitated fake notifications from major social networking sites. Messages allegedly sent on behalf of Facebook informed recipients that a lot had happened on friends’ news feeds since they last visited the site and they were prompted to open the attached archive to find out more. The archive contained the backdoor from the aforementioned Andromeda family.
Meanwhile, ‘Nigerian’ scammers could not pass up the opportunity to exploit the situation in Ukraine and the tragic events that followed in order to cheat users out of their money. They cited some familiar stories about unfortunate tourists in Kiev who had all their money stolen, followed by a request for financial assistance.
"Phishing emails that use the names of major financial and e-payment organizations from different countries are being actively spread by scammers to steal personal financial information. A successful attack usually gives the phishers full access to the victim's personal account on the banks’ website," says Tatyana Shcherbakova, Senior Spam Analyst at Kaspersky Lab.
