Zero-day exploit for Japanese word processor Ichitaro
Trend Micro notes increase in regionally targeted attacks as trojan becomes latest to exploit a Ichitaro flaw.
A trojan has been found to be exploiting a buffer overflow vulnerability in popular Japanese word processing package Ichitaro.
According to analysts
at Trend Micro a backdoor trojan is installed when a malicious .JTD file is opened in Ichitaro 2006 running on
the Japanese version of Windows XP SP2.
Trend detects the malicious .JTD file as TROJ_TARODROP.AB, and the backdoor it installs as
BKDR_AGENT.AIAJ.
Trend researchers note that the number of targeted attacks on Japanese applications has increased over the past 12
months - and that this is the second Ichitaro exploit in the space of six months.
The vulnerability is reported by Symantec in an advisory here.
More from Trend analysts can be found in their blog here. For users of Ichitaro a security update patching
the vulnerability can be downloaded here.
