- Chainalysis security breach exposed customer data and raised phishing risk
Chainalysis confirmed on 30 October 2026 that an external actor accessed its systems and internal tools earlier in October, using what it called "offensive agentic techniques". Exposed data covers some customers' names, emails, job titles, user IDs and role labels. Chainalysis says it has found no access to passwords, session tokens or investigation content so far, and customers should expect targeted phishing. Affected-customer counts and the exploited vulnerabilities are not disclosed.

Passkeys Are Better Than Passwords. But They Are Not Enough.Opinion piece arguing that passkeys, built on public-key cryptography, resist phishing, credential stuffing and password theft but do not settle identity risk. Attackers can go around them through account enrollment before a passkey is bound, weaker recovery paths (SMS, email link, help desk), device changes and authenticated session hijacking. It proposes layering identity threat detection with risk-based, continuous evaluation of trust.

Five extensions were purchased from legitimate developers and turned malicious via updates; the framework included 16 modules covering a multi-chain wallet drainer, Ledger/Trezor recovery-phrase phishing, credential/form theft, crypto exchange session harvesting, CSP-header stripping, and a persistent WebSocket C2 channel. The Edge version of "Enable Right Click & Copy โ Smart Unlock + OCR" remained live and received a new C2 domain even after the Chrome listing was removed.

Huntress security team shares their internal strategy for running monthly phishing simulations, including how they rotate lures (payment offers, spoofed conferencing tools), track click rates and report-before-click as success metrics, and use repeat-clicker data to target individualized training. Includes real click-rate trends from their own employees across January-February campaigns showing how difficulty escalation and exposure therapy reduce susceptibility over time.

Huntress details five modern phishing techniques that bypass traditional "check the URL" training and MFA: ClickFix (fake CAPTCHA tricking users into running Win+R/paste commands to execute malware), Browser-in-the-Browser (fake HTML popup windows mimicking OAuth login prompts with forged address bars/padlocks), ConsentFix (dragging an identity icon to leak an OAuth authorization code that attackers trade for Microsoft Entra ID access/refresh tokens), device code phishing (abusing the legitimate microsoft.com/devicelogin flow to authorize an attacker's device via a code, seen weaponized in PhaaS kits like EvilTokens), and fake video-conference (Teams/Zoom/Google Meet) waiting-room overlays that push a malicious "driver update" install. Each section explains why the technique defeats standard security-awareness training and how Huntress's simulated phishing scenarios replicate it.

Dark Caracal Reloaded: GoCaracal โ New Go Malware With Ethereum-Based C2 FallbackArctic Wolf Labs documents GoCaracal, a previously undocumented modular Go-based malware framework attributed with medium confidence to Dark Caracal (linked to Lebanon's GDGS), deployed alongside an updated Bandook variant in a June 2026 intrusion against a Venezuelan communications organization. The extended GoCaracal build features a novel Ethereum smart-contract (BulletproofC2) fallback that lets operators update C2 addresses via on-chain transactions without redeploying malware, and analysis of 249 samples traces the framework's four-phase development from January to July 2026. The report includes delivery-chain details (SVG phishing, URL shorteners, Delphi loader), infrastructure analysis (AEZA Group, AlexHost hosting), a YARA rule, and IOCs for detection.

Shai-Hulud was the best thing to happen to supply chain securityAikido Security tracks npm's Trusted Publishing (OIDC-based, short-lived credential) adoption over 18 months and shows it only spiked after each major supply-chain attack rather than from advisories or blog posts โ jumping from a ~40/week baseline to 430/week after the Nx Console/AntV compromise, yet still leaving 40,369 of the top 51,370 packages (75% of download volume) on long-lived tokens. It chronicles the full attack progression from credential-phishing (Debug/Chalk, Axios) through Pwn Request-driven CI compromise (S1ngularity, Shai-Hulud 2.0) to the Mini Shai-Hulud II/TanStack attack, which poisoned the GitHub Actions cache to extract a live OIDC token from runner memory and publish packages with valid SLSA Build Level 3 provenance โ proving Trusted Publishing itself can be turned into the attack vector rather than just bypassed. It closes by arguing the security community should proactively pressure high-download holdout maintainers rather than wait for the next worm.

Socket: "Offside Wallet Theft Factory"Socket's Threat Research team tracked 77 linked Firefox extension identities in a campaign dubbed "Offside Wallet Theft Factory": 40 are confirmed malicious (impersonating OKX, Rabby Wallet, TronLink and others) and 37 are deceptive sports-score shell extensions later repurposed into wallet stealers. Techniques include Supabase-controlled remote phishing switches, Cloudflare Worker exfiltration of recovery phrases, modified Rabby Wallet code that exfiltrates serialized keyrings via persistAllKeyrings() before local encryption, and hardcoded C2 servers stealing credentials and clipboard data. The post includes full SHA-256/IOC listings and shows how extension identities are repurposed over version history from benign utilities into wallet-draining malware.

Huntress researchers document a phishing campaign targeting Black Hat/DEF CON attendees via X DMs impersonating a CoinDesk exec, luring victims into opening a weaponized Google Doc with a custom Google Apps Script sidebar that runs a fake "decryption" flow before delivering ClickFix-style commands or a manual "update" that drops malware. On macOS this delivers AMOS infostealer plus a LaunchDaemon-based polling backdoor with SOCKS5 proxy capability; a follow-up fake DocSend/Dropbox installer delivers a ClickOnce/NSIS loader chain on Windows that installs NetSupport RAT, a process-hollowed rogue Certificate Authority that MITMs VirusTotal traffic, and an incomplete Ledger wallet-targeting implant. The piece includes deep technical detail on the loader's C2 protocol, stolen/fraudulent code-signing certificates, and infrastructure patterns (multi-branded loader domains), plus mitigation guidance and a link to published IOCs.

How to Spot and Stop Rogue Device JoinsWiz details how attackers abuse Entra ID's Device Registration Service to register rogue devices โ often via device code phishing โ to satisfy Conditional Access policies requiring joined devices, commonly using the open-source ROADrecon framework and predictable names like DESKTOP-XXXXXXXX. As attackers shift to AI-generated, benign-looking device names (e.g., "Work PC") and plausible User-Agent strings, static IOC matching breaks down, so Wiz shifted to behavioral detections: naming-convention anomaly detection against tenant baselines and correlating device-code-phishing alerts with subsequent device registrations, including a shared KQL query for identifying anomalous naming baselines.

Zero-Click AI Browser Hacking: Claude and ChatGPT Atlas Hijacked via Emails, X PostsSecurityWeek covers Zenity's 'PleaseFix' research disclosing zero-click indirect prompt injection attacks against OpenAI's ChatGPT Atlas and Anthropic's Claude in Chrome browser extension. In Atlas, a single planted X comment triggers 'intent collision' that resurrects CSRF-like cross-site abuse, letting the agent read WhatsApp Web contacts to send phishing messages or manipulate Amazon carts and use Amazon's Rufus assistant to complete unauthorized purchases. In Claude in Chrome, a malicious email with hidden prompt instructions triggers the agent to import a payload from a rogue NPM package hosted on a fake CDN, enabling exfiltration of Gmail inbox contents via the Atom feed, mass-sharing of Google Drive files, and full account takeover of Slack and X by intercepting MFA codes.
