In the second of our five-part series, Sophos X-Ops investigates the so-called ‘white’ (legitimate) business interests of threat actors

Sophos X-Ops investigates what financially motivated threat actors invest their ill-gotten profits in, once the dust has settled

Imagine this: Your organization completed its annual penetration test in January, earning high marks for security compliance. In February, your development team deployed a routine software update. By April, attackers had already exploited a vulnerability introduced in that February update, gaining access to customer data weeks before being finally detected. This situation isn’t theoretical: it

Ransomware has evolved into a deceptive, highly coordinated and dangerously sophisticated threat capable of crippling organizations of any size. Cybercriminals now exploit even legitimate IT tools to infiltrate networks and launch ransomware attacks. In a chilling example, Microsoft recently disclosed how threat actors misused its Quick Assist remote assistance tool to deploy the destructive

A Russia-linked threat actor has been attributed to a cyber espionage operation targeting webmail servers such as Roundcube, Horde, MDaemon, and Zimbra via cross-site scripting (XSS) vulnerabilities, including a then-zero-day in MDaemon, according to new findings from ESET. The activity, which commenced in 2023, has been codenamed Operation RoundPress by the Slovak cybersecurity company. It…

Cybersecurity researchers have discovered a malicious package named “os-info-checker-es6” that disguises itself as an operating system information utility to stealthily drop a next-stage payload onto compromised systems. “This campaign employs clever Unicode-based steganography to hide its initial malicious code and utilizes a Google Calendar event short link as a dynamic dropper for its final

Google on Wednesday released updates to address four security issues in its Chrome web browser, including one for which it said there exists an exploit in the wild. The high-severity vulnerability, tracked as CVE-2025-4664 (CVSS score: 4.3), has been characterized as a case of insufficient policy enforcement in a component called Loader. “Insufficient policy enforcement…

Salary savings come with hidden costs, including insider threats and depleted cybersecurity defenses, conveying advantages to skilled adversaries, experts argue.

A new study by researchers at Princeton University and Sentient shows it’s surprisingly easy to trigger malicious behavior from AI agents by implanting fake “memories” into the data they rely on for making decisions.

The security software maker said the vulnerabilities in Endpoint Manager Mobile have been exploited in the wild against “a very limited number of customers” — for now — and stem from open source libraries.
