Cybersecurity researchers have shed light on a WordPress compromise in which threat actors deployed multiple persistence mechanisms to ensure that the final payload kept returning without having to infect the site again.

The backdoor has been codenamed SC after the “SC_” markers present in the injected content. Sucuri has described the malware as a “self-healing mesh” that’s

This week, the useful words are boring ones: inspect, cache, compile, store, trust. Each sounds harmless. Each can become an attack path when a system does a little more than people expect. A model check can run code. A cache can mix up requests. A public secret can stay useful for years.

That is the lesson running through the list. Attackers do not always need a brilliant new trick. They can

Police in Spain have arrested a 16-year-old whom investigators suspect of running the KillSec ransomware group. KillSec is accused of stealing data from organizations and threatening to publish it on its leak site unless they paid.

The 16-year-old was one of 3 people arrested on September 30, when police also took control of that site.

Investigators identified him as KillSec’s suspected

European police said raids against the KillSec ransomware-as-a-service operation included the arrest of a high-profile teen suspect.

Two separate reports by cybersecurity companies highlight China-linked hacking operations, including a phishing campaign that impersonated Western experts.

The findings, released Thursday by Asymmetric Security, are just the latest example of rogue behavior spurred by OpenAI’s software.

Security researchers have published the first public proof-of-concept for CVE-2026-86950, an Apple CoreGraphics flaw Apple says may have been used in attacks against specific targeted individuals.

The trigger is a malicious PDF with a crafted embedded font that crashes unpatched iPhones and Macs. The code causes a crash, not an execution error. Turning the memory corruption into a working

Google on Wednesday announced its latest frontier artificial intelligence (AI) model, Gemini 4 Argon, that it said is being rolled out to a set of trusted cyber defenders through its Fairwind Program.

“It delivers frontier performance in complex workflows across real-world software engineering, enterprise knowledge work like legal and finance, and cybersecurity defense,” Koray Kavukcuoglu,

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Wednesday added a critical authentication bypass flaw impacting Cisco Catalyst SD-WAN Manager to its Known Exploited Vulnerabilities (KEV), following reports of active exploitation.

The vulnerability, tracked as CVE-2026-76504 (CVSS score: 9.8), could allow an unauthenticated, remote attacker to access an affected system with

OpenAI on Wednesday said it identified and disrupted a coordinated distillation campaign that was designed to illicitly extract protected reasoning from its artificial intelligence (AI) models.

A “core cluster of the activity,” going back to the first week of July, has been attributed to individuals associated with Moonshot AI, a Chinese AI company based in Beijing. It did not cite any
