[QUOTE="dax123, post: 120008, member: 8137"] First of all, I must say there are some misunderstandings, for the test was not based on proper technical background. [B]Actually both SD and Diskshot passed the test, and the thing TDSSKiller detects is only leftover.[/B] To Understand this, we need to know the way the 'Sinowal' code works. The head developer (of the Diskshot) said that malware is very 'stupid' because the infection code runs only on ring3, and is not technically sophiscated at all(in a point of rootkit infection). there's an analysis of the rootkit Sinowal: [url=http://stoned-vienna.com/html/index.php?page=analysis-of-sinowal]http://stoned-vienna.com/html/index.php?page=analysis-of-sinowal[/url] According to this, Sinowal exploits some remaining sectors(that every windows-installed HDD has to have), and locates their main code to the end of HDD sector, like TDLFS filesystem. Basically, Diskshot and Shadow defnder only prevents the system drive(and MBR) from modification, so any remaining partition is left behind. to describe the problem, let me show this picture... [attachment=4405] so like a gun without a trigger, the remaining code (at the end of the HDD) will never be executed.. But TDSSKiller detects the (neutralised)remainings and warns it to user.. He(who tested these software) didn't know that fact and just relied on what TDSSkiller says, so he could say there were failures.. [B]above all, your system is still safe while you are using SD / Diskshot.[/B] if you want to erase the remaings, you could use TDSSKiller or bcwipe or ccleaner etc. PS: The developer told me that to get around the misunderstandings shown above, Diskshot will apply whitelist protection mechanism as of DS@Home 3.8. (which prevents any modification of the entire HDD partitions except specified) And DS@home could have some AV engine (especially for password-stealing trojans/sophiscated rootkits), trying to prevent online system infection (like returnil) Regards ;D [/QUOTE]
