Last month’s post examining the top email-based malware attacks received so much attention and provocative feedback that I thought it was worth revisiting. I assembled it because victims of cyberheists rarely discover or disclose how they got infected with the Trojan that helped thieves siphon their money, and I wanted to test conventional wisdom about the source of these attacks.
While the data from the past month again shows why that wisdom remains conventional, I believe the subject is worth periodically revisiting because it serves as a reminder that these attacks can be stealthier than they appear at first glance.
Nearly every time I write about a small to mid-sized business that has lost hundreds of thousands of dollars after falling victim to a malicious software attack, readers ask how the perpetrators broke through the victim organization’s defenses, and which type of malware paved the way. Normally, victim companies don’t know or disclose that information, so to get a better idea, I’ve put together a rough profile of the top daily email-based malware attacks over the past month.
A crackdown by the Chinese government on anonymous domain name registrations has chased spammers from Chinese registrars (.cn) to those that handle the registration of Russian (.ru) Web site names, new spam figures suggest. Yet, those spammy domains may soon migrate to yet another country, as Russia is set to enforce a policy similar to China’s beginning April 1.
