Kaspersky Lab: Kaspersky Lab Reports Significant Increase Of In-The-Wild Threats In September 2008 Statistics; Rootkit Program Replaces Trojan As The Most Prolific Malware Detected On Kaspersky Lab Users' Computers


(M2 PressWIRE Via Acquire Media NewsEdge)
RDATE:03102008

Kaspersky Lab, a leading provider of security solutions that protect
against viruses, Trojans, worms, spyware, crimeware, rootkits,
phishing, hacker attacks and spam, today revealed that 35,103 different
malicious and potentially unwanted programs were detected on users'
computers by the Kaspersky Security Network (KSN) during September
2008. This represents an increase of 6,163 on August 2008 statistics
and two consecutive months of growth.

In Kaspersky Lab's top twenty ranking of malicious programs detected
onitsusers' computersduring September 2008 the KSN recorded a change at
the top of the chart with the former leader,
Trojan.Win32.DNSChanger.ech, leaving the top twenty and being replaced
by Rootkit.Win32.Agent.cvx. Kaspersky Lab first detected and added the
rootkit to its anti-malware databases on 28th August 2008 and
throughout September it actively spread across the Internet.

Senior Virus Analyst at Kaspersky Lab, Aleks Gostev states, "Two
factors have set the alarm bells ringing. First of all, rootkits are
notoriously awkward customers for antivirus software and secondly, very
few antivirus programs, as yet, can detect this particular specimen."

Gostev comments on other revelations from the top twenty, "A
significant amount of the attacks on users' computers stem from various
script downloaders. These scripts act as the "trigger" for the majority
of "drive-by download" attacks." Such a Trojan downloader -
Trojan-Downloader.WMA.Wimad.n - returned to the ranking in second place
in September. This multimedia file exploits a vulnerability in Windows
Media Player to download various Trojans.

Interestingly, not only have all the AdWare programs from last month -
not-a-virus:AdWare.Win32.BHO.ca; not-a-virus:AdWare.Win32.BHO.sc and
not-a-virus:AdWare.Win32.BHO.vp- remained in the top twenty, they have
consolidated their positions (9th, 11th, 13th and 14th positions).

In Kaspersky Lab's top twenty ranking of the most common malicious
programs among all infected objects detectedon users' computers the
changes were minimal compared to August with only four new entries
(3rd, 5th, 15th and 20th), however the majority of the programs have
file-infection capabilities.

Net-Worm.Win32.Nimda,which unexpectedly claimed first place in
August2008, has been replaced by Virus.Win32.Xorer.duat the top of the
ranking.

During September several programs and variants have strengthened their
position in this ranking. Notably another member of the Sality family
enter therankingin 5th position - Virus.Win32.Sality.aa-bringing their
number to four.The worm - Worm.Win32.Mabezat.b- has become another
programto be reckoned with. It initially showed no significant activity
after being detected by Kaspersky Lab in November 2007, as it probably
went about gradually increasing the number of infected machines and
files. Now it has entered the ranking at third place.

Gostev concludes, "Overall, it has to be said that the state of virus
and worm activity is rather stable and shows no signs of getting worse.
According to KSN data, a number of malicious programs that infect files
have been significantly curtailed over the last three months, which is
borne out in the examples of the Allaple and Otwycal families falling
off of our ranking."
