Targeted Trojan Horses Are the Future of Malware
Good article:
Security technology can stop common attacks, but targeted attacks fly under the radar. That’s because traditional products, which scan e-mail at the network gateway or on the desktop, can’t recognize the threat. Alarm bells will ring if a new attack targets thousands of people or more, but not if just a handful of e-mails laden with a new Trojan horse is sent.
“It is very much sweeping in under the radar,” said Graham Cluley, a senior technology consultant at Sophos, a U.K.-based antivirus company. If it is a big attack, security companies would know something is up, because it hits their customers’ systems and their own honeypots (traps set up to catch new and existing threats), he said.
Targeted attacks are, at most, a blip on the radar in the big scheme of security problems, researchers said. MessageLabs pulls about 3 million pieces of malicious software out of e-mail messages every day. Only seven of those can be classified as a targeted Trojan attack, said Alex Shipp, a senior antivirus technologist at the e-mail security company.
“A typical targeted attack will consist of between one and 10 similar e-mails directed at between one and three organizations,” Shipp said. “By far the most common form of attack is to send just one e-mail to one organization.”
