IPV4/IPV6 Obfuscation

Created the Monday 19 August 2024. Updated 3 months, 1 week ago.

The obfuscated payload masquerades itself as an array of ASCII IPv4 addresses. Each one of these IPs is passed to the RtlIpv4StringToAddressA function, which will translate the ASCII IP string to binary. The binary representation of all of these IPs is combined to form a blob of shellcode. Additionally, IPfuscation variants were spotted using IPv6 instead of IPv4 addresses, UUIDs, and MAC addresses, all operating in almost the same way.
