Cisco has revealed that three distinct threat clusters linked to ransomware and state-sponsored attacks have been exploiting two recently patched Secure Firewall Management Center (FMC) vulnerabilities. The attacks leverage CVE-2026-20079 (CVSS score: 10.0), an authentication bypass vulnerability in the web interface of FMC software that could allow an unauthenticated, remote attacker to bypass authentication and execute script files on an affected device to obtain root access to the underlying operating system. The second flaw under exploitation is CVE-2026-20316 (CVSS score: 5.3), which could allow an unauthenticated, remote attacker to log in to an affected device using a low-privilege account to access sensitive data within susceptible systems. It can be paired with other Cisco Secure FMC vulnerabilities to elevate privileges. Cisco Talos said it identified three clusters of post-compromise activity of FMC instances associated with state-sponsored and crimeware threat act...

A lot of this week’s security news has the same awkward answer to one question: “Why was that allowed to work?” An extension asks for access and takes too much. A trusted service becomes part of a phishing chain. An old bug still gets results. An exposed system stays exposed. A package looks useful right up until it isn’t. Different stories, same basic problem: the path in was often already there. Nothing here needed magic. Mostly access, trust, weak edges, and someone willing to keep poking. That’s the week. The threats change every week. Subscribe, and we’ll alert you when each new ThreatsDay Bulletin is out.

The worst part is how normal these attacks look. A call from IT. A shared file. A trusted app. A simple request to click “Allow.” Why break in when someone might open the door? That idea runs through this edition. Attackers use real tools, fake login pages, old account links, and software guides that point to unsafe downloads. One wrong letter in a web address can be enough. There is also ransomware, stolen ID data, hidden attack servers, and weak settings that should have been fixed long ago. Here’s the full list.

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Wednesday added seven security flaws to its Known Exploited Vulnerabilities ( KEV ) catalog after they landed in attackers' crosshairs. The vulnerabilities are as follows - CVE-2026-83548 (CVSS score: 10.0) - A server-side request forgery vulnerability in SonicWall SMA 1000 Appliances that could allow a remote unauthenticated attacker to gain unauthorized access to sensitive functionality and perform unauthorized operations.  CVE-2026-83549 (CVSS score: 7.8) - A post-authentication operating system command injection vulnerability in SonicWall SMA 1000 Appliances that could enable a remote authenticated attacker as administrator to execute arbitrary OS commands, resulting in remote code execution. CVE-2026-9586 (CVSS score: 9.3) - An SQL injection vulnerability in Sangoma Switchvox that could allow an unauthenticated remote attacker to execute arbitrary SQL statements against the backend PostgreSQL...

The most common way into a company last year was to ask. A web page tells the visitor to prove they are not a robot. While they read the instructions, it quietly places a command on their clipboard. Then it talks them through opening a terminal and pasting it in. The technique is called ClickFix, and it was the most common initial access method Microsoft’s team observed last year , accounting for 47% of the attacks in their notifications. Nothing arrives as an attachment, so there is nothing to scan. No vulnerability is used, so there is nothing to patch. What happens next is just as ordinary. When Bitdefender analyzed 700,000 security incidents , 84% of the high-severity ones involved binaries that were already on the machine - the same administrative tools your IT team uses every day. Nothing malicious was installed, because nothing malicious was needed. Neither technique is clever, but both are winning. And the reason is not that attackers have run out of ideas. It is that th...
