Threat Group Cards: A Threat Actor Encyclopedia Archived: 2026-04-05 19:08:10 UTC Home > List all groups > List all tools > List all groups using tool BernhardPOS Tool: BernhardPOS Names BernhardPOS Category Malware Type POS malware, Credential stealer Description (securitykitten) What makes BernhardPOS stand out is the use of code that continues to evade AV detection. Between manually resolving imports when they are needed and inserting junk code between legit operations, this malware stays successfully hidden. It manually encodes the strings that it needs to in order to evade a simple string based rule. And it doesn’t heavily pack or encrypt itself in a way that would set off high entropy rules. In most network scenarios, DNS is a port left wide open due to machines needing to communicate with one another and the larger Internet. Leveraging DNS allows the malware authors to not worry about being blocked by a firewall or hindered by network restrictions.
