Security Articles

Daily threat intelligence and vulnerability analysis from our security team. We publish expert breakdowns of critical CVEs, active exploits, and emerging attack campaigns as they happen.

Our analysts monitor vendor advisories, CISA alerts, and underground threat activity to give you actionable guidance you can use the same day. Filter by severity below to find what matters most to your environment.

Updated October 29, 2026 — all 245 published advisories are browsable here. The five drawing the most attention right now: North Korea’s Lazarus group breaching at least three companies through a fake job-candidate portfolio site that turned a trusted sign-in security plugin into the way in, then running its spying tools only in memory — there is no patch and no CVE, so remove security plugins nobody needs and tell HR and hiring managers that a polished résumé site followed by an “allow this plugin” prompt is a call to the security team, not a click; an attacker replaying stolen Microsoft 365 sign-in tokens (the pass Microsoft hands you after the password and multifactor prompt are already done) to take over 97 accounts at 79 organizations, registering rogue devices, swapping the multifactor app and hiding emails about payroll, direct deposit and bank details with inbox rules — there is no patch, because nothing is broken, and a password reset alone does not evict the attacker, so after any mailbox compromise also remove unknown devices and multifactor methods and check for hidden inbox rules; Apple finally fixing an actively exploited iPhone and iPad flaw on older devices that cannot run the newest iOS, a bug in how the device draws images that lets a booby-trapped file run an attacker’s code (CVE-2026-86950, rated 8.8 out of 10, on CISA’s actively exploited list since September 29) — the iPhone XS, XS Max and XR and several older iPads went about four weeks with no fix at all, and those hand-me-down phones and lobby tablets are the devices nobody checks, so find anything still on iOS 18 and update it to 18.7.11 this week; two emergency fixes for PHP, the language running underneath WordPress and most small-business websites and customer portals, after flaws nicknamed PHP2Shell let someone with no login take over the server (CVE-2026-109618 and CVE-2026-109619, each rated 9.2 out of 10) — attackers began trying them before the fixes shipped, and a fully patched website does not help if the PHP underneath it is old, so ask your web host or developer to confirm you are on PHP 8.5.12, 8.4.27, 8.3.36 or 8.2.35; and attackers planting backdoors on Nextcloud file-sharing servers through the built-in Collabora document-editing add-on, with no login, then hunting the company files for password vaults and crypto wallets (CVE-2026-110447, rated 9.2 out of 10, now on CISA’s actively exploited list) — the fix shipped September 11 but the warning only went out October 14, so update the add-on to 26.4.303 or remove it, then check for a backdoor, because on a server that was already hit the update is the start of the cleanup, not the end. Four of the five have already been used in real attacks, attackers are already trying the fifth, and for three of them (Lazarus, Microsoft 365 and Collabora) an update or a password reset alone does not make you safe. The cost is decided by how fast someone notices. If nobody is reading the alerts at 2 a.m., our 24/7 staffed security operations center handles the detection and the response.

HIGH: Fortinet FortiGate Firewalls Hit by Stealthy PEERSTITCH Implant

Unit 42 has exposed PEERSTITCH, a memory resident implant that a suspected nation-state cluster tracked as CL-STA-0954 planted on FortiGate firewalls after breaching a telecom MSP's FortiManager through FortiJump. The implant abuses FortiOS flaw CVE-2025-61624, now in CISA KEV, to let tagged VPN sessions skip security checks, and patching alone does not undo the stolen configs and credentials for more than 500 firewalls.

CRITICAL: Gunra Ransomware Exploits Fortinet FortiOS Auth Bypass Flaws

CISA, the FBI, and South Korea's National Police Agency issued joint advisory AA26-222A on the Gunra ransomware group, which is breaching networks through the Fortinet FortiOS and FortiProxy authentication bypass flaws CVE-2024-55591 and CVE-2025-24472. Gunra has claimed fifty-one victims across healthcare, finance, government, and manufacturing, and tampers with VDI authentication files to create a persistent MFA bypass before destroying backups and encrypting with ChaCha20.

CRITICAL: Coldcard Seed Flaw Linked to $70 Million Bitcoin Theft

A firmware integration error shipped in March 2021 routed Coldcard seed generation to a deterministic software PRNG instead of the STM32 hardware RNG, cutting effective entropy to as low as 40 bits. An attacker drained 1,196 Bitcoin addresses of 1,082.65 BTC worth roughly $70.2 million in 41 minutes on July 30, 2026, without ever touching a device. Coinkite shipped emergency firmware on July 31, but updating does not repair a seed that was already generated.

HIGH: Miasma Worm Detonates 73 Microsoft GitHub Repos in npm Supply Chain Cascade

GitHub disabled 73 repositories across four Microsoft organizations after the Miasma worm spread through 57 npm packages, including @vapi-ai/server-sdk and ai-sdk-ollama. The TeamPCP-linked variant of Mini Shai-Hulud uses a Phantom Gyp binding.gyp injection plus AI coding assistant rule files in Claude Code, Cursor, Gemini CLI, and VS Code to harvest AWS, GCP, Azure, Vault, and GitHub Actions credentials.

HIGH: Bitwarden CLI Hit by Shai-Hulud Third Coming Worm in Checkmarx Supply Chain Cascade

A poisoned build of @bitwarden/cli version 2026.4.0 lived on the npm registry for roughly ninety minutes on April 22, 2026, infecting around 334 developer machines with the third generation of the Shai-Hulud worm. The attack chained off the prior compromise of the checkmarx/ast-github-action GitHub Action, harvested cloud credentials, GitHub and npm tokens, and AI coding tool configs, then self-propagated by injecting malicious workflows into accessible repositories.
