SEOUL, South Korea, Oct 31, 2011 (BUSINESS WIRE) —
–Smartphone security still at risk with rising Android and Mac malware threats
–Cloud computing represents new frontier for cyber criminals
Trojans remain the most reported malicious code in the third quarter
according to recent findings from AhnLab Inc. (
a leading provider of integrated security solutions. In the most recent
AhnLab Security Emergency Response Center (ASEC) report, Trojans
represented the most reported malicious code at 37.2%, as well as
accounting for 36% of the top new malicious codes during the third
quarter of 2011.
Based on a sampling pool of users in Korea, Trojans dominated the top
twenty most reported malicious codes for the third quarter, followed by
script (20.7%), and worm (10.8%). When examining the top 20 malicious
codes reported in the third quarter of 2011, Textimage/Autorun ranks top
at 16.2% (1,702,118 reported cases), followed by JS/Agent at 13.6%
(1,429,508 reported cases) and the new Html/Agent at 9.7% (1,016,109
The third quarter saw a decrease in malicious code reports as compared
to the previous quarter, which dropped 6,601,706 to 39,606,178. However,
13 new malicious identified codes made up part of the top 20 malicious
codes for the quarter.
Trojans are the most reported new malicious code, representing 36% of
the top reported new malicious codes. It is followed by script at 22%
and adware at 12%. Specifically, TextImage/Autorun is the most reported
new malicious code at 17.1% (1,699,603 reported cases) of the top 20 new
malicious codes, followed by JS/Agent at 14.4% (1,429,439 reported
The ASEC Report revealed that Microsoft security updates continue to
demonstrate vulnerabilities. As in the first and second quarters, system
vulnerabilities were the most prominent, marking 41% of updates, while
IE vulnerabilities marked the least amount of updates at 4%.
Global Malicious Code Trends–Third Quarter
In its most recent ASEC report, AhnLab emphasizes that malicious code
trends in the third quarter are similar to that of the second quarter.
The number of malicious codes distributed by exploiting vulnerabilities
As has been seen previously, most malicious code variants are restricted
by specific regions. As regionalization of malicious codes becomes more
pervasive, global malicious code statistics are no longer significant.
Distribution of malicious codes remains common by hacking websites and
exploiting vulnerabilities to insert malicious codes. However,
distributing malicious codes via email or social network sites, such as
Facebook and Twitter is also becoming increasingly common.
Threats to smartphone security remain an issue in the third quarter. A
malware posing as a PDF file was reported to infect Mac OS X and a new
piece of Android Malware called GingerMaster has been found exploiting
Android 2.3 (Gingerbread). GingerMaster exploits Android 2.3 and
harvests data on infected Android smartphones and then sends the stolen
information to a remote server. AhnLab cautions that extra care must be
taken as smartphone security threats will continue to increase.
Cloud computing represents one of the most exciting technology trends
and the antivirus industry has not been slow to embrace this
opportunity. In fact, AhnLab, Inc. has added a cloud-based technology,
AhnLab Smart Defense (ASD) to its product line. Hackers and cyber
criminals have also been quick to take advantage of this trend and a
rogue cloud antivirus ‘OpenCloud Antivirus’ was reported in September.
This rogue system pretends to scan the system and claims to identify
multiple infected files. Similar to other rogue antivirus, this system
will trick victims into purchasing a license for the software. AhnLab
warns users to exercise caution when implementing a cloud antivirus
