Due to this, it’s straightforward to determine such samples as 888 RAT.

In later variations of the 888 RAT (not the cracked RAT builder), we observed that the builder was able to obfuscating strings (command strings, C&C, and different plain textual content strings) by encrypting them utilizing AES with a hardcoded key; nevertheless, the bundle identify nonetheless remained the identical.
