“Greediest banking malware”: The start of summer also brought a change at the top of this category. June’s leader seems somewhat sluggish in the summer heat, however: Trojan-Banker.Win32.Banker.ohq attacked customers of a total of 56 banks—almost 50 fewer than its predecessor.
-
“Greediest malware targeting electronic-payment systems”: Trojan-Banker.Win32.Banker.olr targeted one more victim than the previous month’s winner. Customers of three payment systems fell within its reach in June.
-
“Greediest malware targeting key cards”: In June, one modification of Trojan-PSW.Win32.Agent.apl won this category after attacking users of four payment-card systems.
-
“Best-hidden malware”: June changes everything. Here too, a new leader emerged. Trojan-PSW.Win32.Delf.jj had been packed eight times using different compression programs.
-
“Smallest malware”: Larger than its predecessors but still vanishingly tiny, June’s leader in this category was Trojan.BAT.KillFiles.hx. Despite measuring just 26 bytes, it was capable of destroying the entire contents of a hard drive.
-
“Largest malware”: The largest threats appear to be settling at a lower average size in 2008 than last year. In June, Trojan-Banker.Win32.Bancos.mk was crowned the month’s “largest” at “only” 31 MB.
-
“Most hostile malware”: This month’s winner comes from the same family as May’s leader. One modification of Backdoor.Win32.Agobot.gen removes numerous security products, including antivirus software, from the infected PC’s memory and hard drive.
-
“Most widespread malware in email traffic”: “Never change a running system”—this month, as in previous months, Email-Worm.Win32.Netsky.q again won this category, accounting for 34.15 percent of malicious traffic.
-
“Most widespread Trojan family”: There was a change among Trojan families, however: the Trojan-GameThief.Win32.OnlineGames family displaced the previous month’s leader, and with good reason. No fewer than 3,295 modifications of this malware were identified.
-
“Most widespread virus and worm family”: In the first month of summer, the worm family with the most members was Worm.Win32.Autorun. With 152 previously unseen modifications, however, the family delivered a relatively modest showing.
