Mallory pivots from this family to the IOCs, detections, and named campaigns that touch your stack, and pages you when something new lands.
6 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).”

Observed dropping Rhadamanthys as a follow-on payload.
A newly observed generic backdoor/loader that injects and launches code in explorer.exe using syscalls such as NtOpenProcess, NtWriteVirtualMemory, and NtCreateThreadEx. It collects host information, requests updated versions of itself, and beacons to a hardcoded C2 IP. Samples were protected with the ALCATRAZ obfuscator.
A Windows backdoor that uses NtOpenProcess, NtWriteVirtualMemory, and NtCreateThreadEx to launch unbacked code in explorer.exe. It collects host information, retrieves updated versions of itself, and beacons to a hardcoded C2 IP address.
