Hi Polonus,

Not a new exploit method given in your post regarding “wire-transfer.htm”.

I’ve seen the exact algorithm somewhere else.

Hi !Donovan,

Well then they are running a new campaign with this again. So old wine in new sacks, so to say. Thanks for your evaluation.
I just report what I see happening while scanning and when I cannot get a avast detection, I immediately report back to the avast base,
well analysts. I think you are developing a very good “feel” for the various varieties of malcoded scripts out there,
as it is inspiring for both of us,

Malware sent yesterday to avast but still no detection ?

Hi MDRockstar,

This because the suspicious file ltastd.exe is flagged as riskware. It might be opened by avast to be run first in sandbox for evaluation,

polonus

819

Not many of the larger AVs are detecting it either. Many that are are using heuristics and are calling it PUP or riskware.

820

Hi DavidR,

Thank you for confirming the PUP status. The poster probably sent it because of this report: http://systemexplorer.net/db/ltastd.exe.html
