Mallory pivots from this family to the IOCs, detections, and named campaigns that touch your stack, and pages you when something new lands.
3 distinct techniques documented for this family, organized by ATT&CK tactic.
“ALCATRAZ moves the entrypoint then includes additional code with an algorithm to calculate the new entrypoint of the program.” | “ALCATRAZ... [uses] control flow flattening, instruction mutation, constant unfolding, LEA constant hiding, anti-disassembly tricks and entrypoint obfuscation.” | “ALCATRAZ implements one form of this technique by modifying any instructions starting with the 0xFF byte by adding a short jump instruction (0xEB) in front.” | “It restructures execution using a centralized dispatcher, which determines the next basic block to execute based on a state variable, making analysis and decompilation significantly more difficult.” | “The simple add instruction gets transformed to 5 different instructions (push, not, sub, pop, sub).”

An open-source x64 binary obfuscator used in attempts to evade detection and hinder analysis.
An open-source x64 binary obfuscator used in attempts to evade endpoint detection and hinder analysis.
An open-source binary-to-binary obfuscator initially released in January 2023. It supports entrypoint obfuscation, anti-disassembly, instruction mutation, constant unfolding, LEA obfuscation, and control-flow flattening; it was used to protect DOUBLELOADER.
