ICMP-Ghost v3.6.3 hardens DNS tunneling with 5-domain rotation, RFC 4648 Base32 encoding, and A record QTYPE — eliminating static fingerprinting for rule-based NDR systems like Suricata and Snort.
BYOVD loads a signed vulnerable driver, exploits it for arbitrary kernel R/W, and terminates EDR at Ring 0 — Windows-only, noisy at driver load time, requires admin. User-space injection (Phantom Evasion Loader) uses SROP frames via sys_rt_sigreturn to fire ptrace without a direct ptrace syscall sequence, writes payload in a single process_vm_writev call (syscall 311), redirects RIP into target process — implant runs inside cron’s address space with cron’s identity. Linux-only. Results: 0/65 VirusTotal static, SROP and process_vm_writev invisible to Hatching Triage behavioral sandbox, only ptrace attach entry detected.
Static analysis tools and AI-driven EDRs map malicious behavior through branching instructions — JMP, JZ, JNZ form the edges of a Control Flow Graph that heuristic engines traverse. CMOV-based CFG flattening removes all conditional branches, collapsing the graph to a single flat node sequence that defeats both signature-based and ML-based detection. Full x64 Assembly implementation: branch-free syscall obfuscation, CMOV patterns for JZ/JNZ/JLE replacement, and empirical bypass results against NGAV and Ghidra CFG analysis.
Standard ptrace injection generates detectable syscall sequences that EDR hooks intercept. Phantom Evasion Loader routes ptrace through SROP frames: crafting a fake sigcontext on the stack and firing sys_rt_sigreturn (syscall 15) causes the kernel to restore arbitrary register state — ptrace fires through the signal return path, invisible to direct syscall monitors. process_vm_writev (syscall 311) writes the full payload in one cross-process memory operation instead of 204 PTRACE_POKEDATA events. QWORD XOR decryption runs in-memory before injection. Results: 0/65 VirusTotal static, SROP + process_vm_writev invisible to Hatching Triage behavioral sandbox.
Standard Assembly code with absolute addresses breaks under ASLR — fixed addresses become invalid at runtime. PIC solves this via RIP-relative addressing: all memory references computed as offsets from the current instruction pointer. The Stack Anchor technique carves a 32KB R/W region (sub rsp,0x8000 + and rsp,-16 + mov rbp,rsp), providing writable storage without .data or .bss sections. Read-only templates in .text are copied to the stack via rep movsb for runtime modification. Result: a single position-independent code block deployable anywhere in memory — standard for shellcode, injection payloads, and fileless implants.
