Overview

Signed By: Microsoft Corporation
Status: Valid

The signature on 13 is reported as valid. A valid signature helps confirm publisher identity, but it does not automatically make the file safe if the installer was bundled, abused, or downloaded from an untrusted source.

Common Places:

%appdata%\agdata\bin
%programfiles%\anonymizergadget
%sysdrive%\config.msi
%sysdrive%\\program files (x86)\steam\bin\cef\cef.win7

%temp%\tencent\qqmusic
%sysdrive%\$windows.~bt\sources\panther\migrationshims\migshim1
%appdata%\tencent\tim\autemp\18122697\7dofe805\oldfiles

ThreatInfo has observed 13 in the locations listed above. Files found in temporary folders, user profile folders, startup locations, or unusual application directories should be reviewed more carefully than files installed under a known program directory.

File Names:

6 observed names
msvcp140.dll 3dbcd56e.rbf 134d0029.rbf 2c663.rbf 1 13

This hash has been seen with multiple file names. Alternate names can appear when software is updated, copied between folders, packed by an installer, or deliberately renamed to avoid recognition. Compare the exact MD5 above before assuming two names refer to the same file.
