After a long time, a sample still not being detected
« on: January 09, 2012, 07:29:26 PM »
Hello guys,

I already submitted this file multiple time by the we interface, by email, etc... To no avail...

I dont know why this sample is not detected yet... Theres more than 1 month that I had submitted it.. I received in an email pretending to be from a bank... A lot of other avs already detect this...

Here is the sample:

Thanks for your time,

Hello Polonus!

Thanks for your reply.

But it seems that the reports that you put in your reply are not the smae file that I submitted yesterday. Their Md5 Hash are different, and their detection of the other avs.

Thanks!

Hello,
thank you for sendng sample. It is self-extracting rar archive - the file inside is already detected (if it runs and unpackes the file). But we have to analyze, why this archive is not unpacked when scanning.

Oh, I understood now.

So this file would not be detected by a full system scan, only by executing it?

Thanks for the reply!
