The cybercrime group Qilin has emerged as the world's most active ransomware affiliate program, claiming at least 365 victim organizations in the past three months alone. But even top Russian hackers make operational security mistakes, and the administrator of Qilin has made a few key missteps over the last decade that all point to a 36-year-old man living in St. Petersburg, Russia.
Microsoft did another four-digit patch drop today, releasing updates to fix almost 1,100 security vulnerabilities in its Windows operating systems and supported software. This month's Patch Tuesday addresses 63 critical flaws -- including a zero-day in Microsoft Outlook -- and comes amid important security updates from other software makers, including Adobe, Apple, Google and Mozilla.
Several staffers at the White House are using computers or mobile devices equipped with residential proxy services that render their internet address available for others to rent, security experts warned today. One of the proxy services is a Russian company whose founder's web hosting business was ground zero for cyberattacks against election systems in Arizona and Illinois in 2016.
Google said today it worked with industry partners to dismantle a botnet made up of more than 1.3 million Android TV set-top boxes that ship with malicious software which secretly rents the user's Internet connection out to strangers and conducts advertising fraud. Experts involved in the takedown say the action is likely to sever the botnet's access to more than 10 million additional compromised systems, including other Internet of Things (IoT) products such as Android-based healthcare devices and karaoke machines.
Expect to see quite a few websites serving "404" or "Page Not Found" errors today: Nearly 70 percent of websites need to update their core software to fix a pair of vulnerabilities that allow an attacker to seize full control over affected servers. Experts say there are working exploits for the flaws, and that these critical bugs are already being exploited in the wild.

Security teams have more alerts, logs, and monitoring tools than ever. Yet when an attack happens, one simple question can still take too long to answer: Who or what is behind this activity, and what can they access? A suspicious login might belong to an employee. An unusual API call could come from a machine account. Or an AI agent might be accessing sensitive systems using permissions nobody
A search result isn't always safe. An access request isn't always harmless. And a familiar account doesn't always mean a familiar person is using it. Simple things to remember. Yet a surprising amount of this week's trouble starts right there. Attackers are using fake websites, stolen access, and trusted tools to get into places they shouldn't be. AI is helping them build attacks faster, while
Public exploit code released earlier this week claims that a local Windows user can gain SYSTEM privileges through the Common Log File System driver. The proof of concept, called SignDrop, targets a log-authentication feature added to the driver last year. It abuses how clfs.sys creates companion files when a privileged process opens a prepared log, using path redirection to take control of
A critical flaw in Red Hat Quay allows an attacker who can access a Quay registry to read and overwrite private container images in every repository. Quay enables anonymous access by default, and while it is enabled, the attacker needs no account. When it is off, anyone with a valid account can still exploit the flaw, Red Hat said yesterday. The company has released fixed builds for eight Quay
Citrix has released patches for multiple critical security flaws impacting NetScaler ADC, Citrix NetScaler Gateway, and NetScaler Console that could lead to denial-of-service (DoS) or an authentication bypass. The critical vulnerabilities that impact NetScaler ADC and NetScaler Gateway are listed below - CVE-2026-120868 (CVSS score: 9.3) - A memory overflow vulnerability in Packet
