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 3, 2026 — all 220 published advisories are browsable here. The four drawing the most attention right now: a FortiMail email-gateway flaw being exploited before any fix exists (CVE-2026-104286, rated 9 out of 10 for severity) — there is no patch yet, so every affected 8.0, 7.6, 7.4 and 7.2 system is relying on Fortinet’s workaround, starting with switching off the Identity Based Encryption portal if you do not use it; two Citrix NetScaler flaws exploited for weeks before the September 27 fix (CVE-2026-88771 and CVE-2026-88772) — a patched box can still be hosting a webshell (a hidden back door left behind in the software itself), so update to 14.1-73.37 or 13.1-64.23 and then go looking for what was left behind; a Roundcube webmail flaw that lets an attacker tamper with the mail database before anyone logs in (CVE-2026-48842), patched in May 2026 and still being exploited because it ships inside hosting control panels most firms forget they run; and a Microsoft SharePoint Server flaw under active attack that lets an intruder run their own code on the server holding your internal documents (CVE-2026-65660), whose CISA federal patch deadline passed on September 28, so an unpatched server is now overdue rather than pending. Two of the four are email systems, and one has no fix at all, which is why what decides the cost is how fast someone notices. If you are not sure who is reading the alerts at 2 a.m., our 24/7 staffed security operations center handles the detection and the response.
A logic flaw in the Linux kernel algif_aead module gives any unprivileged local user root access on every major distro released since 2017. CISA added CVE-2026-31431 to the KEV catalog with a mandatory federal patch deadline. If you run Linux servers, patch today or assume compromise.
CISA added the two-year-old ConnectWise ScreenConnect path traversal flaw CVE-2024-1708 to its Known Exploited Vulnerabilities catalog on April 28, 2026, after China-aligned Storm-1175 was caught chaining it with the SlashAndGrab auth bypass CVE-2024-1709 to deploy Medusa ransomware through compromised MSP infrastructure. Federal agencies have until May 12 to remediate.
Read moreMicrosoft has confirmed active exploitation of CVE-2026-32202, a Windows Shell spoofing flaw that turns out to be an incomplete patch for an APT28 zero-day from earlier this year. The Russian GRU-linked group is using crafted LNK files to silently steal NTLM credentials with zero clicks, and the original April 14 advisory dramatically understated the severity until Microsoft corrected it on April 27.
Read moreA 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.
Read moreA server-side request forgery flaw in the LMDeploy vision-language pipeline was under active exploitation twelve hours and thirty-one minutes after public disclosure, and no upstream patch has shipped yet. Attackers are already probing exposed instances for AWS metadata credentials, Redis on localhost, and loopback services.
Read moreApple shipped iOS 26.4.2, iPadOS 26.4.2, iOS 18.7.8, and iPadOS 18.7.8 to fix CVE-2026-28950, a data retention flaw in the Notification Services framework that kept the text of deleted notifications in an internal database. The FBI used the bug to recover Signal message content from a seized iPhone after the Signal app had been deleted. Patch every managed iPhone today and enforce preview redaction on sensitive messaging apps.
Read moreThree zero-day vulnerabilities in Microsoft Defender, nicknamed BlueHammer, RedSun, and UnDefend, are under active exploitation after researcher Chaotic Eclipse dumped working proof-of-concept code. Only BlueHammer (CVE-2026-33825, CVSS 7.8) has been patched. RedSun escalates local users to SYSTEM on fully patched systems while UnDefend silently disables Defender definition updates, making the chained attack especially dangerous until the May 13 Patch Tuesday.
Read moreScattered Spider, the group behind the MGM and Caesars attacks, has hit Marks & Spencer, Co-op, and Harrods in a coordinated campaign deploying DragonForce ransomware. The attacks relied on social engineering help desk staff rather than technical exploits.
Read moreCitizen Lab revealed that law enforcement agencies worldwide are using Webloc, a tool built by Israeli intelligence company Cobwebs Technologies, to track 500 million mobile devices through advertising data without warrants. Clients include ICE, US military, and police departments across America.
Read moreThe official CPUID website was compromised for 19 hours, redirecting users to malicious downloads of CPU-Z and HWMonitor that delivered STX RAT. Over 150 victims identified across retail, manufacturing, telecom, and individual users in Brazil, Russia, and China.
Read moreFortinet has disclosed that threat actors are using a symlink-based technique to maintain read-only access to FortiGate devices even after security patches are applied. The method exploits the SSL-VPN language files directory to create persistent filesystem access.
Read moreSecurity researchers discovered 36 malicious npm packages impersonating Strapi CMS plugins. The packages exploit Redis and PostgreSQL databases, deploy reverse shells, harvest credentials, and target cryptocurrency platforms with hard-coded database credentials.
Read moreGoogle patched CVE-2026-5281, a high-severity use-after-free vulnerability in Chrome's Dawn WebGPU implementation that is being actively exploited in the wild. This marks the fourth Chrome zero-day of 2026, and CISA has already added it to the Known Exploited Vulnerabilities catalog.
Read moreCensys discovered CTRL, a Russian RAT using named pipes and RDP tunneling to evade network monitoring. Built to stay hidden while maintaining full network access.
Read moreOver 340 organizations across five countries compromised in aggressive device code phishing campaign exploiting OAuth device authorization flow. Attackers harvest tokens that survive password resets using PhaaS platform EvilTokens.
Read moreU.S. authorities dismantled four IoT botnets (AISURU, Kimwolf, JackSkid, Mossad) responsible for the largest DDoS attacks ever recorded. Over 3 million enslaved devices generated attacks exceeding 31 Tbps.
Read moreOver 2,000 Kubernetes clusters compromised through RBAC misconfigurations. Attackers deploy cryptominers via default service accounts. Check your clusters now.
Read moreGoogle patched CVE-2026-3909 (Skia OOB write) and CVE-2026-3910 (V8 sandbox escape), both CVSS 8.8 and actively exploited. CISA added to KEV with March 27 deadline. Update to Chrome 146.0.7680.75/76.
Read moreTwo Chrome Featured extensions, QuickLens and ShotBird, turned malicious after ownership transfer. Attackers stripped security headers, injected C2 payloads via 1x1 pixel images, and deployed ClickFix-style attacks for full endpoint compromise. Extension supply chain attacks are accelerating.
Read moreAkamai confirmed Russia's APT28 was exploiting CVE-2026-21513 in Windows MSHTML before Microsoft released the February patch. The attack chains crafted LNK files to bypass Mark-of-the-Web and IE Enhanced Security, delivering payloads without user interaction.
