Greetings.
I’m somewhat new to the ClamAV world, so my apologies up front.
I’m attempting to determine if a specific ransomware, Friedex.d, a variant of
Iencrypt, is being scanned for with the current definitions.
I came across an article that basically said to dump the database and search
for the name. So I did,
# mkdir signatures
# cd signatures
# sigtool –unpack=/var/lib/clamav/main.cvd
# grep -i “ransom.win32.friedex.d” *
# grep -i “efc3418eb170c6bf503140cff504eec8” *
## MD5 hash of the Ransomware
# grep -i “be30850f25e01c84f218022199791911ce64b580” *
## SHA1 hash
No results from any of those greps. My immediate thought is that it’s not in
the definition files. But then I can’t find anywhere on the website to submit
data for a known piece of ransomware that ClamAV does not appear to have
defined. Here’s the data that I have:
Threat Type
Targeted Ransomware
Virus Name
Ransom.Win32.FRIEDEX.D Variant of Iencrypt
Hash
MD5: efc3418eb170c6bf503140cff504eec8 SHA1:
be30850f25e01c84f218022199791911ce64b580
IP Point of Origin
Empire C2: 185.92.74.215 Brute Force: 185.92.74.133
Other tools
Mimikatz PowerShell Empire PS-EXEC
Virus Details
SIZE: 135,168 FILE TYPE: EXE MEMORY RESIDENT: Yes ENCRYPTED: Yes
Perhaps I just am not looking correctly, or I’m not looking in the right place?
Or maybe I’m just going about this hunt in the wrong way!
Thank you in advance!
