Top Tweets for #KLBanker

@0xToxin @crocodylii Interesting find !!
VCRUNTIME140.pdb reminds me of #KLBanker as well since the DLL was often named like that.
Do you have any hashes for your sample? Would love to have a look π

In this sample the Banker DLL is over 4MB instead of around 1MB.
Protection: invalid code to the methods so that decompilers cannot interpret them. Example AntiDecompiler Cleaner hosted on Github.
Didn't contact paste4btc or pastebin to fetch config info

Interesting .NET #Brazilian Banker ...
Possible #Janeleiro or maybe a #Mekotio .NET variant based upon the .PDB path containing "KL_FINAL" -> reference to "KL_Banker" ? which is another name for #Mekotio.
CustomAction in .MSI Installer
-> AI_Detect VM
-> AMJEJCNE is a Script

#Banking #Brazilian #malware maybe related with #Lampion.
By pdb: #KLBanker
Loader for W7 & W10
