Researchers found a flaw in Opera GX, the gaming-focused version of the Opera browser, that let a malicious website silently install a browser add-on and use it to lift specific data from the pages a victim visits. In a proof of concept, they reconstructed a signed-in user’s full Gmail address from a single visit, with no click. Opera has patched the flaw and says it found no evidence that

Scanners meant to catch malicious add-on “skills” for AI coding agents can be fooled by a few simple changes that leave the malware working, according to a new study from researchers at the Hong Kong University of Science and Technology. Their strongest trick slipped past every scanner tested more than 90% of the time, and the same team built a runtime checker that catches most of the

A public proof-of-concept is now out for CVE-2026-55200, a critical flaw in libssh2 that lets a malicious or compromised SSH server trigger memory corruption on a connecting client, with possible code execution. No credentials, no user interaction. The bug affects every release up to and including 1.11.1 and carries a CVSS 4.0 score of 9.2. libssh2 is a client-side SSH library, not a server.

Cybersecurity researchers have uncovered two hijacked npm packages and a cluster of Go packages that are designed to deploy a Python-based information stealer on compromised Windows, Linux, and macOS hosts. “This attack avoids the most common npm execution paths through lifecycle scripts, perhaps in an attempt to remain ‘compatible’ with npm v12’s security hardenings,” JFrog said in a

Canada’s spy service got a judge’s permission to reach into infected servers, home routers, and IoT gear sitting on Canadian soil and neutralize two foreign-run botnets. The Federal Court released a public version of the ruling on June 15. It is the first time the Canadian Security Intelligence Service has used its threat reduction warrant powers this way. The warrant let CSIS alter,

A new malware family is turning forgotten home routers into a distributed reconnaissance and proxy network, not the DDoS botnet these devices usually end up in. QiAnXin’s XLab calls it AryStinger and counts at least 4,300 infected routers, a total it says is still rising. The distinction matters. AryStinger exists for the stage of an attack that comes before the break-in. Infected
