Deep exploits Windows errors in October patch

According to Finnish security firm F-Secure, Dasher.B, after penetrating into Windows 2000 and Windows XP computers, it has not installed MS05-051 patch table, will automatically load a rootkit capable of detecting keyboard characters ( keylogger) located on a remote server.

Before Dasher.B launched a day, December 14, the Dasher.A worm, created based on the exploit code posted online two weeks ago, also appeared. However, the first version could not go far due to programming errors and was placed on a server that no longer operates in China.

Two Dasher variants are not a big risk, but it shows that malicious program writers are still scouring around for Windows vulnerabilities.

At the end of November, Microsoft also acknowledged that the exploit code for MSDTC in MS05-051 has begun to be circulated on the network but confirmed that hackers could not control the system remotely.
