Those naughty, malicious little malware writers are becoming increasingly clever and creative in the way they go about spreading infections and misery across the Internet.
From polymorphic file infectors to autorun
exploitations, malware writers are becoming “increasingly creative with
their ways,” according to BitDefender, as it reveals, in its May report
on the top 10 e-threats detected during the month, that first place on
the list goes not to a piece of malware, but rather to an infection
technique - the autorun.inf exploitation code found in threats as
diverse as Conficker and Sality.
“Topping out at 9.93% of detections, it is the most widespread exploit and the top e-threat of the month,” says BitDefender.
According to BitDefender, the top ten e-threats detected in the month
of May were, almost all Trojans, with “simple, user-interaction driven
pieces of malware occupying no less than six of the ten positions.”
And, in second place, BitDefender lists what it calls "the positively
ancient Trojan.Clicker.CM”, a popup-serving program with a “whopping
9.23% of detections.”
BitDefender also reports that Conficker is “on the up again for some
reason,” claiming the fifth position in May with 3.12% of detected
infections, and, it says, a lowly bit of SWF exploit code, heavily used
in malicious and compromised websites the world over, can be found in
fourth, at 4.33%.
A polymorphic file infector claimed sixth place in May and, says
BitDefender, “if that sounds dangerous, that’s because it is: the virus
infects executable files as well as network shares, re-writing itself
in the process to avoid signature-based scanners.”
