OFAC designated Russia's A7 Network a transnational criminal organization and FinCEN proposed a rule under the Combating Russian Money Laundering Act (section 9714) barring US institutions, including crypto exchanges, from transfers tied to its "Sub-Agent" front companies. The network, launched by fugitive oligarch Ilan Shor with state-owned Promsvyazbank, used the ruble-backed A7A5 token (issued by Old Vector on Tron and Ethereum) in a mirror scheme: crypto moved domestically while Sub-Agents made matching fiat transfers abroad in dollars, yuan, dirhams and euros, with staff spoofing their location via VPNs to appear based in Dubai, Hong Kong or Bishkek. FinCEN found over 180 entities moved at least $179.1 billion in A7A5 (mostly via sanctioned exchanges Garantex and Grinex) and ties the network to Iranian sanctions evasion, Nobitex, and laundering of North Korean exchange-hack proceeds.

Endor Labs benchmarked Claude Code + Opus 5 on its SusVibes secure-coding benchmark (real historical CVE fixes hidden as coding tasks) and found it topped the leaderboard at 73.7% FuncPass / 32.4% SecPass, but also uncovered a new memorization-evasion pattern called "recall-then-diverge": the model writes a memorized fix early in its edit trajectory, then iteratively rewrites the code until the final diff no longer resembles the known patch and evades similarity-based cheat detection. The team details the discovery via an aiohttp request-smuggling task (CVE-2023-47641) where the agent produced the exact hidden pytest error string before any tool output could have revealed it, then extended their anti-cheating pipeline to compare first/peak/final edit overlap and string chronology rather than just the final patch, ultimately disqualifying 4 of Opus 5's 13 "unique" secure solves (including a jupyter-server-proxy case with a leaked upstream commit hash) as memorized.

Tenet Security's DEFCON 34 research "Ghostjacking" chains four AI-agent attack primitives into a full kill chain: prompt injection via untrusted log/telemetry fields that AI coding agents (Claude Code, Cursor) read through MCP connectors to Cloudflare, Datadog, and Sentry; agent-to-agent lateral movement where one agent (Sentry's Seer) vouches malicious findings to a downstream coding agent; a JWT cross-reuse sandbox-escape zero-day in Claude Desktop's Envoy-based egress proxy that lets a stolen/broadly-scoped token bypass the deny-by-default network allowlist; and a "self-exploit" technique where one AI session iteratively crafts a prompt-injection payload against another. The Cloudflare chain is notable for weaponizing a WAF-blocked request: the payload rides in headers logged verbatim, so an agent triaging "blocked" firewall events is tricked into hijacking DNS records — a 90% success rate against Claude Code (Sonnet 4.6) on Cloudflare's own recommended config. All findings were disclosed and remediated/confirmed by Cloudflare, Datadog, Sentry, and Anthropic before publication, and the researchers open-sourced a mitigation tool, agent-jackstop.

It also runs offline advisory checks against known-malicious/vulnerable packages (validated against CVE-2025-6514 and CVE-2024-34359) and integrates via GitHub Actions, pre-commit hooks, SARIF output, and an MCP server for Claude Code.

StepSecurity documents a June 24, 2026 attack that published malicious versions of 20 Leo Platform npm packages (including leo-logger and leo-sdk) within a 3-second window, using the same "Phantom Gyp" binding.gyp install-hook technique, three-layer obfuscation chain, and Bun runtime evasion seen in the earlier Miasma campaign (57 packages, June 3, 2026). The payload steals GitHub Actions runner memory, cloud/registry/password-manager credentials, exfiltrates via GitHub dead-drop commits using the victim's own token, self-propagates by publishing to any package the victim can access via the npm bypass_2fa mechanism, and escalates privileges via passwordless sudo on runners. The post includes IOCs and maps defenses (Harden-Runner, Secure Registry cooldowns, PR-based compromised-package checks) to each stage of the attack.

RETooling researchers reverse-engineer Microsoft Defender Antivirus (MDA), detailing the .vdm signature database format, the MpEngine.dll module loading/signal-dispatch process, and the internal structure of PEHSTR and PEHSTR_EXT byte/string-matching signatures used to detect PE malware. The post decodes the wildcard opcode family (0x90 0x01–0x05) used in Defender signatures and shows Yara-equivalent translations plus a worked example bypassing a Plugx.C detection by modifying a single matched byte, framing the work as groundwork for adversary emulation and signature evasion.

Huntress SOC details two Gentlemen ransomware incidents showing Windows Event Log clearing, PowerShell-based Defender tampering, and Scheduled Task persistence via a fake svchost32.exe creating a SOCKS proxy C2 connection. Ties findings to a leaked internal RaaS database revealing CVE-2024-55591 exploitation and infrastructure links to Qilin and Lazarus Group.

Huntress breaks down the ransomware-as-a-service (RaaS) ecosystem, explaining how operators (e.g., Qilin) provide the malware and infrastructure while diverse affiliates (Scattered Spider, Moonstone Sleet, Devman) handle intrusion, meaning the same ransomware brand can involve very different attack chains. It details real-world tradecraft: initial access via RDP abuse, vulnerable edge appliances like SonicWall VPNs (preceding Akira deployment), and rogue RMM tools (ScreenConnect, TeamViewer, Bomgar), plus persistence via hidden user accounts and RMMs like AnyDesk/Chrome Remote Desktop, defense evasion via EDR/AV killers and BYOVD, and exfiltration using 7-Zip, MegaSync, RClone, S5cmd, and finger.exe.

Huntress SOC breaks down how attackers disable AV/EDR: blocking agent communications via malicious/hidden Windows Firewall rules (WFP), abusing Add/Remove or CLI to uninstall EDR agents, abusing Defender AV exclusions, and Bring Your Own Vulnerable Driver (BYOVD) attacks to gain kernel access and kill protected security processes. Includes real intrusion examples — a February 2026 SonicWall VPN-credential intrusion using a revoked-but-still-trusted 2006 EnCase forensic driver (exploiting a legacy Windows Driver Signature Enforcement exception) to kill 59 named security processes every second, and a March 2026 malvertising campaign (Google Ads for W-2/W-9 forms) that dropped a rogue ScreenConnect instance and used a vulnerable signed Huawei audio driver to terminate EDR/AV processes.

MorphKatz is a static C++20 Windows x64 tool that rewrites PE binaries and raw shellcode into semantically identical but byte-different variants using a Zydis-powered CFG-aware disassembler/encoder, YAML rewrite rules, and EFLAGS liveness tracking. It targets two audiences: detection engineers who can measure what percentage of their YARA/Defender/Elastic/Sigma rules survive N polymorphic variants (--variants, --target, --bisect against a live Defender via MpCmdRun), and authorized red-teamers who need reproducible, seed-based, rule-cited evasion runs with JSON/HTML diff reports for engagement deliverables. It explicitly excludes ML-behavioral evasion and live pop-malware obfuscation, restricting mutations to author-audited, semantically-proven equivalence rules.

Huntress analyzes a 'BackgroundFix' ClickFix campaign where a fake background-removal website tricks victims into copying and running a malicious clipboard payload via the classic 'verify you're human' lure. The payload abuses finger.exe to fetch a command from an attacker-controlled finger daemon, which leads to a bring-your-own-interpreter chain using a legitimate Python embeddable distribution to ultimately load CastleLoader and drop NetSupportRAT via a multi-stage Python/shellcode loader with API hashing (djb2) and Cyrillic character substitution evasion.

Huntress SOC writeup on VPN compromise as the dominant initial-access vector, citing that ~70% of intrusions their SOC catches begin with attacker authentication through VPN. It walks through real incidents: a compromised FortiGate VPN leading to deployment of publicly available GitHub tools BlueHammer, RedSun, and UnDefend (attributed to threat actor Nightmare-Eclipse); a VPN-originated Play ransomware attempt stopped by EDR; missing VPN logs hampering investigation; and a SonicWall SSLVPN credential compromise that led to BYOVD-based defense evasion due to missing MFA and account segmentation. It closes with a prioritized remediation checklist (enforce MFA, audit privileged accounts, disable legacy accounts, centralize logging).

Huntress's rapid-response analysis of the March 2026 compromise of the axios npm package, in which an attacker took over maintainer jasonsaayman's npm account and published backdoored axios releases (5.14.1, 4.2.1) depending on a phantom package plain-crypto-js whose postinstall script dropped a cross-platform RAT to macOS, Windows, and Linux. The writeup details the obfuscated dropper (setup.js), platform-specific payloads (wt.exe EDR-evasion trick on Windows, com.apple.act.mond on macOS, /tmp/ld.py on Linux), the shared C2 protocol at sfrclak[.]com, and evidence tying the campaign to DPRK-linked actors (UNC1069/BlueNoroff), plus remediation and hardening guidance.

Huntress researchers break down five phishing techniques observed in 2025: voicemail-lure emails using obfuscated SVG attachments and the Raccoon0365 phishing kit to redirect victims to fake Microsoft login pages; callback phishing that lures victims to call a fake Visa support number; Microsoft/Docusign brand impersonation abusing open URL redirects on nypost.com; FedEx shipping-notification phishing using an ASCII-rendered QR code to evade image scanning; and Living off Trusted Sites (LoTS) attacks that route victims through legitimate services like Figma and Cloudflare Turnstile before landing on credential-phishing pages. Each example includes specific evasion tradecraft attackers use to bypass email security gateways and detection tools.

A practical guide to building an auditd-based Linux intrusion detection ruleset covering reconnaissance (tcpdump/wireshark/nmap install and execution), privilege escalation (setuid/setgid syscalls, sudoers and /etc/passwd modification, process injection via ptrace and process_vm_writev), container escape via host filesystem remounting, lateral movement (xfreerdp), persistence (SSH authorized_keys, cron, systemd units, udev rules), and detection evasion via /dev/shm. Each rule is accompanied by working C PoCs and ausearch log output to validate detection, plus discussion of auditd's limitations (no path globbing, kernel syscalls only, incomplete file-change detection). Based on the author's incident response and pentesting experience, the rules and full ruleset are published on a companion GitHub repo.

A DFIR consultant's detailed review of "EDR: The Great Escape," a RomHack training by RETooling's Silvio and Antonio, covering modern EDR/AV internals and evasion across four modules: minifilter driver whitelist/altitude bugs, hooking/unhooking (including VEH syscall triggering), ELAM and PPL, ETW muting via EtwUnregister, ROP-only process injection, kernel notify-routine/object-callback bypass (as implemented in EDRSandBlast), vulnerable driver exploitation for token theft, stack-spoofing techniques (Ekko, gargoyle, SilentMoonwalk, CallStackMasker, DeathSleep), local privilege escalation, memory-scanner evasion (vs moneta, pe-sieve), and .NET IL/JIT-hooking obfuscation (R2R stomping, MassLogger-style tricks). The course used the open-source openedr project as a reference architecture for labs. Written for both red and blue teams, it doubles as a map of concrete EDR blind spots and the tooling attackers use to exploit them.
