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.

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.

Keystone, a hardware wallet maker, will destroy 18,835 unsold devices after an attacker used a flaw in a third-party data monitoring tool to breach its website on 20 October 2026. The breach exposed 25,964 buyer records and a factory-set authenticity key that cannot be changed, so counterfeit wallets could pass checks. An automated deletion tool had failed unnoticed against the 180-day retention policy. The report also covers a Foundation breach with 23,000 phishing attempts.

An interview with Solana Foundation CISO Michael Coates dissects the July 2026 Coldcard hardware-wallet hack, where a 2021 code change swapped a hardware RNG for a software pseudo-random source, collapsing seed entropy from 128 to ~40 bits and letting attackers offline-brute-force and drain ~$116M in Bitcoin from 5,200+ wallets without touching a device — despite prior audits that only checked whether a value was set, not its source. Coates draws lessons on distrusting single audits, using multi-sig to remove single points of failure (including the wrench attack), and phishing-resistant hardware keys (e.g. YubiKey) as the fix for pixel-perfect deepfake and phishing attacks. He also discusses AI's cat-and-mouse effect on offense vs. defense, Anthropic's disclosed Claude-driven Chinese state espionage campaign, and Solana's STRIDE continuous security-rating program for DeFi as an automated, computer-scale response to agentic nation-state threats.

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.

Aikido 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 — 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 — 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.

Huntress SOC documents a recurring attack pattern from late 2025 where threat actors gain initial access via phishing-delivered RMM installers such as GoTo Resolve, PDQ, and ITarian, then use that foothold to deploy a secondary rogue RMM such as ScreenConnect or SimpleHelp for redundant persistence, sometimes chaining three RMMs in one intrusion. It walks through specific incidents at a real estate firm, investment firm, and car dealer, including file paths, C2 domains, and phishing lures like fake invitations and a fake Microsoft Teams bid transcript, and closes with detection guidance such as asset inventory, the LOLRMM list, and log auditing.

Huntress details a December 2025 incident where attackers used SEO poisoning to surface fake, attacker-created ChatGPT and Grok shared conversations as top Google results for benign queries like "clear disk space on macOS." Victims who followed the AI-formatted "troubleshooting" instructions and pasted a Terminal command triggered a multi-stage AMOS (Atomic macOS Stealer) infection: a bash loader silently validated the user's password via `dscl -authonly`, escalated to root via `sudo -S`, deployed a hidden `.helper` Mach-O payload, trojanized Ledger Wallet and Trezor Suite apps to steal seed phrases, and persisted via a LaunchDaemon-driven AppleScript watchdog that relaunches under the active GUI user's session every second. The piece is notable as the first documented case of AMOS using AI-platform-hosted content (rather than phishing or fake installers) as the initial lure, and includes defender detection guidance (monitoring osascript credential prompts, dscl -authonly usage, sudo -u with piped passwords, hidden dotfiles).

Huntress CEO Kyle Hanslovan demonstrates a full modern account-takeover chain against Microsoft 365: buying stolen credentials on a dark web marketplace, using a ChatGPT-crafted phishing email with a fake SharePoint link to trigger a ClickFix-style CAPTCHA that tricks the victim into pasting a PowerShell command, stealing active session cookies with an infostealer, and importing them via the Cookie Editor browser extension to bypass MFA entirely. It then covers post-compromise tradecraft — malicious inbox rules to forward/hide sensitive emails, Teams-based social engineering of IT support to register new MFA devices, and abusing email-based password resets on non-SSO apps (payroll, CRM) — plus defensive recommendations (conditional access, inbox rule auditing, DMARC/DKIM/BIMI, session revocation processes, security awareness training).
