Virtualine is a Russian-speaking bulletproof hosting provider whose domain virtualine.net the FBI seized. Court documents say it hosted phishing, spam, carding and illicit content, and ignored abuse reports. TRM Labs says it received more illicit-attributed cryptocurrency than any other labeled bulletproof host, mostly from a Russian drug marketplace (44%) and a sextortion scheme (17%), and later from StealC operators in 2026.

Walks through a post-exploitation credential-harvesting technique on Linux: enabling password authentication in sshd_config, writing a pam_exec.so logging script, and inserting it into /etc/pam.d/sshd (or common-auth/password-auth) so every SSH login attempt is logged with username, password, and source host to a hidden log file. Also covers using each user's ~/.ssh/known_hosts to identify pivot targets for lateral movement during a pentest.

Rapid7 details a new BPFDoor campaign targeting telecom and network-edge appliances (ShareTech, SpamSniper mail gateways) and a six-sample Linux RAT family dubbed AVERAT found on compromised Taiwanese CPE (Synology NAS, a NetKlass device, a Dahua DVR). The writeup reconstructs the Rapid7 BPFDoor controller's HTTP-tunneled trigger mechanism, a fileless ShareTech dropper that stages binaries as ntpdate/udevds and deletes them while processes keep running, a BPF Rekoobe variant that hides inside SMTP port-25 traffic, and AVERAT's RC4-derived config/C2 scheme — tying the infrastructure to the broader China-nexus ORB (Operational Relay Box) device pattern described in CISA/NCSC-UK advisory AA26-113A. It closes with detection guidance for unlinked/deleted process execution, dropper staging artifacts, and port-25 C2 callbacks, plus full IOC and ATT&CK tables.

A survey of how package managers confine install-time and build-time code. It covers Homebrew 7.0.0's fetch/install split, Landlock sandbox and signed declarative *_steps. It also covers opam, Nix, Bazel, pacman, Swift PM and Deno, and the open sandbox proposals at pnpm, RubyGems, Spack, Cargo, pip and Zig. It sorts the responses into gating (allowlists), confinement and replacement/removal of hooks. It links the topic to coding-agent sandboxes (Seatbelt, Landlock, bubblewrap) and to Shai-Hulud and nx. It argues the open problem is validating a sandboxed phase's output at the hand-off.

Simon Willison reviews Jev, a new class of model from TypeSafe AI dubbed "System One models" (or "decision models"): instead of generating text, it takes a text/structured "state" plus one or more yes/no ("Noul"), multiple-choice, or scored-range questions and returns floating point probabilities/confidence scores, priced at $0.042/million input tokens with free output. The post covers real use cases (classification, spam detection, search reranking over BM25 candidates), community experiments (jevchat, jev-leftpad, jev-2048), open-weight recreations built on Qwen 3.5 (the Kev models and JevBench benchmark), and raises concerns about the model's black-box nature and bias risk, plus Willison's own llm-typesafe plugin for the LLM CLI tool.

Flashbots disclosed a critical storage-aliasing vulnerability in V1 of the Priority Update Registry (PUR), an on-chain price feed contract used by trading integrators like propAMMs. Because lane storage slots were computed as keccak256(target, unbounded caller-controlled index) while the updater-authorization mapping lived at slot 0 with the same keccak256 shape, any caller could craft a lane index that collided with isUpdater[target][attacker], letting them self-authorize as an updater and publish arbitrary prices or deauthorize legitimate updaters. The fix namespaces the lane slot derivation (keccak256(NAMESPACE, target, laneIndex)) to make the preimages structurally non-collidable, and the advisory gives integrators concrete migration guidance since authorizations and lane state must be re-established on the new deployment.

An a16z essay arguing that "AI slop" panics and debates over machine "taste" recur historically (from 18th-century Grub Street pamphleteers to pulp fiction and blogging), and that social science can disaggregate "taste" into distinct mechanisms: Watts and Salganik's music-lab experiments showing hit success is socially contingent rather than quality-driven; Ron Burt's brokerage research showing innovation comes from occupying "structural holes" between disconnected networks; and apprenticeship-based judgment that requires repeated correction over time to develop. The piece concludes that as LLMs absorb entry-level tasks (contracts, financial analysis, code), the real scarce resource isn't taste itself but the social infrastructure — apprenticeship pipelines and undocumented tacit-knowledge networks — that produces people capable of exercising it, and warns firms that eliminate junior roles risk losing senior judgment down the line.

Huntress researchers describe how attackers increasingly abuse legitimate RMM tools like ScreenConnect and AnyDesk instead of custom malware, citing a 277% year-over-year rise in RMM abuse and its presence in nearly 40% of investigated incidents. The piece walks through a real case where a ScreenConnect lure sat dormant for five months before the attacker logged in to hijack a browser session and send spam, and describes how Huntress/AnyDesk staff used RMM access defensively to disrupt an India-based scam call center and a pig-butchering compound. It closes by pitching Huntress's RMM Guard, an app-control feature that inventories and blocks unauthorized RMM installs.

Archcanary is a read-only, layered detection scanner for Arch Linux (and derivatives like EndeavourOS/Manjaro) that checks installed packages, pacman logs, systemd units, eBPF programs, ld.so.preload, DKMS kernel modules, and npm/bun/yarn/pnpm caches against curated and third-party (aur-audit.wtako.net) threat lists. It was built in direct response to a 2026 AUR supply-chain attack in which commit forgery was used to impersonate maintainers and inject npm/bun install hooks delivering an infostealer (Discord tokens, GitHub PATs, SSH keys, Vault tokens) and a CAP_BPF eBPF rootkit into 1600+ PKGBUILDs, plus a separate Russian-spam PKGBUILD injection campaign. It integrates with yay/paru pre-build hooks, systemd timers, auditd, and Lynis, and originated as a fork/expansion of lenucksi/aur-malware-check.

PhishDestroy's shortdot-evidence is a daily-updated GitHub investigation into ShortDot SA, the Luxembourg registry operator behind the .icu, .bond, .cyou, .sbs, .cfd, .buzz and .qpon gTLDs, documenting that 51,985+ tracked domains impersonate brands like Chase, Binance, MetaMask and Ledger and that ~70% of registered domains in these zones carry no DNS records (metric-padding rather than legitimate use). It publishes machine-generated IOC/blocklist files and analytics built from a per-TLD zone-file pull cross-referenced against Spamhaus DBL, SURBL, OpenPhish, URLhaus, PhishTank and AlienVault OTX, and ties the zones to concrete criminal cases (FBI's LabHost domain list, Google v. DOES/Yucheng Chang RICO suits, the Revolver Rabbit XLoader/Formbook C2 campaign using 500k+ .bond domains). It also details structural conflicts of interest between ShortDot, its registry infrastructure provider Team Internet Group/CentralNic, registrar partner NameSilo, and the brand-protection vendor NameBlock, backed by Interisle Consulting Group phishing-volume statistics.

Mantis is Google's open-source suite of AI agent skills plus an ADK-based reference harness for autonomous security code review. It walks a codebase to build a semantic index and threat model, generates and executes vulnerability research hypotheses across agents, deduplicates and triages findings to combat LLM hallucination, attempts reproduction (static guesses up to spun-up mock servers), chains findings for impact, and patches issues in an adversarial verify-the-fix loop, calibrating severity against a rubric to avoid inflated "critical" spam. It explicitly warns it is demonstration-only, non-deterministic, and requires isolated sandboxing plus human expert verification before any findings are reported.

Orca Security explainer defining Identity Threat Detection and Response (ITDR) for cloud environments, distinguishing it from IAM, PAM, EDR, and CIEM as a runtime behavioral-detection layer for identity abuse rather than a preventive/posture control. It covers cloud-specific attack patterns like leaked AWS access-key abuse, AssumeRole/PassRole privilege escalation, OAuth consent phishing, and federation/token abuse, and details how ITDR baselines identity behavior (especially machine/non-human identities) using cloud audit logs like CloudTrail to detect impossible travel and anomalous role assumption, ending with Orca's agentless CIEM+ITDR platform pitch.

Huntress SOC dissects a multi-stage infection chain that begins with a malspam HTML attachment routed through a legitimate Google DoubleClick tracking link to evade reputation filters, before landing on a self-personalizing phishing kit and dropping a ZIP with a heavily obfuscated JScript loader. The chain cascades through PowerShell droppers into a .NET stager that performs extensive anti-analysis/anti-sandbox checks, disables Windows Defender, patches AMSI (via NtManageHotPatch on Windows 11 24H2) and ETW at the native API level, and uses RunPE process hollowing into InstallUtil.exe or MSBuild.exe to run a final loader that communicates over AES/RSA-encrypted, protobuf-serialized TCP C2 with certificate pinning. The writeup includes GPU-fingerprinting behavior, persistence via registry Run keys and randomized scheduled tasks, and concrete detection/hardening recommendations.

Huntress documents a malspam campaign, active since February 27, that uses fake "service agreement" document lures behind a CloudFlare CAPTCHA to trick targets into installing Tiflux, a lesser-known Brazil-based commercial RMM, before pivoting to UltraVNC, Splashtop, and ScreenConnect for persistent remote access. The Tiflux installer bundles suspicious extras beyond the legitimate agent: a decade-old UltraVNC build with hardcoded plaintext-recoverable passwords, an expired UltraVNC code-signing cert, registry files that stage a hidden TightVNC service (enabled even in Safe Mode) and a passwordless PuTTY SSH key to a peopleone[.]com[.]br server, registry tweaks that suppress Windows Secure Attention Sequence consent prompts, and a known vulnerable HwRwDrv.sys driver linked to privilege escalation with a revoked signing certificate. Huntress frames this as another entry in the ongoing "LOLRMM" pattern of attackers abusing legitimate commercial RMM tools for stealthy access and persistence.
