New PowerPoint 0-day Trojan in the wild
New zero-day vulnerability in Microsoft PowerPoint has been disclosed.
This vulnerability is being exploited by Trojan horse Trojan.PPDropper.E.
This dropper type file reportedly works in all Windows systems,
but the vulnerability itself has been confirmed in PowerPoint 2000 Chinese
version.
Possibly attackers/targets are located in China area or bad guys just tested
the Trojan with Chinese version.
According to Symantec the exact file size of malicious .PPT file is 1,072,128
bytes.
It drops another Trojan with backdoor capacity.
I put information about the vulnerability to my blog yesterday. There are no
many references available yet.
Especially information about file name being used is very useful.
