SunbeltLabs confirmed the password-stealing Trojan threat Trojan-Spy.Win32.Zbot.gen maintained the top spot on the list for the seventh straight month
Stats from leading anti-malware developer show Trojan-Spy.Win32.Zbot.gen continues to grow at an alarming rate
Clearwater, Florida – November 5, 2009 – Sunbelt Software, a leading provider of Windows security software, today announced the top 10 most prevalent malware threats for the month of October 2009. The report, compiled from monthly scans performed by Sunbelt's award-winning antispyware tool, CounterSpy®, and its anti-malware solution, VIPRE® Antivirus + Antispyware, is a service of SunbeltLabs™.
For October, SunbeltLabs confirmed the password-stealing Trojan threat Trojan-Spy.Win32.Zbot.gen maintained the top spot on the list for the seventh straight month and is growing at an alarming rate, accounting for 8.48 percent of all global malware threats in October, a month over month increase of more than 25 percent on the 6.75 percent it accounted for in September.
The biggest move on the list was made by BehavesLike.Win32.Malware (v), a heuristic detection for software that exhibits behaviours that are typically associated with malicious threats, which more than doubled month on month from 1.55 percent to 3.86 percent. There were seven new entrants to the top 10 in the month of Halloween – typically a key time for new threats to emerge – including Trojan.ASF.Wimad (v) taking number four on the list with 3.35 percent; INF.Autorun (v) at number five with 2.24 percent and Trojan.Win32.FakeXPA (v) at number six with 2.18 percent.
“The threat of Trojan-Spy.Win32.Zbot.gen shows no sign of abating due to its effective versatility in stealing cached passwords, login credentials and data in certificates and cookies,” said Michael St. Neitzel, Sunbelt Software vice president of Threat Research. “The presence of six Trojan detections in the top 10 indicates that Trojans and social engineering from spam email and social networking sites continue to be popular tactics in malware creation.”
The top 10 results represent the number of times a particular malware infection was detected during CounterSpy and VIPRE scans that report back to Sunbelt’s community of opt-in users. All threats are classified moderate to severe based on a number of criteria set out by SunbeltLabs.
The top 10 most prevalent malware threats for the month of October are:
1. Trojan-Spy.Win32.Zbot.gen - 8.48%
