Cisco warned of two high-severity vulnerabilities affecting the Secure Endpoint Connector that allow threat actors to crash the ClamAV scanning process in denial-of-service (DoS) attacks. [...]

Windows Plug and Play can be abused to fetch signed vendor software for an emulated USB device and execute privileged installation components that researchers chained to SYSTEM access on a fully updated Windows 11 machine. The same PnP path can be triggered over Remote Desktop without physical hardware when supported Plug and Play or low-level USB redirection is enabled; Microsoft says that

A malicious tool server connected to an AI coding assistant can quietly walk off with SSH keys, environment secrets, source code, and customer data without ever sending one obviously harmful instruction. The trick can work even after a blunt version of the same theft is refused: split the request into fragments that each look routine, place them in channels the assistant already uses, and let

Marcus Hutchins doesn’t personally consider himself a hacker – but he accepts the epithet because it’s a widely used term for what he once did. The post Hacker Conversations: Marcus Hutchins and the Journey From the Gray Zone to Redemption appeared first on SecurityWeek.

U.S. federal agencies and South Korea's National Policy Agency warned government and critical infrastructure organizations worldwide to secure their systems against Gunra ransomware attacks. [...]

Cybersecurity and intelligence agencies from South Korea and the U.S. warned of Gunra ransomware attacks targeting critical infrastructure sectors and organizations across the world. Targets of these attacks include healthcare and public health, financial services, government services and facilities, and professional and nonprofit services. "Gunra is another variant in the ongoing trend of

Attackers shut down a steam turbine and the process-water treatment system at a Polish combined heat and power plant by coming in over the private cellular network the local grid operator uses to reach remote equipment. The plant supplies heat to roughly 50,000 residents. Recovery began at about 7:30 a.m. while the intruders were still active inside the network, and customers lost neither heat

Cybersecurity researchers have warned of a supply chain compromise impacting WordPress plugin vendor BdThemes, prompting the content management systems (CMS) platform's plugins team to temporarily disable their downloads. "Unlike traditional software supply chain attacks, zero source code files were modified within the official WordPress.org repository," Wordfence researcher Paolo Tresso said.

Hackers breached a heat-and-power plant facility in Poland, which supplies heat to about 50,000 residents, using a private APN (Access Point Name) to access an OT (Operational Technology) network. [...]

New research shows how attackers can use security alerts and blocked events to manipulate and hijack AI agents.

Attacks targeting water systems just keep flowing across a dozen states, against ill-secured, Internet-exposed PLCs.

A threat actor compromised the upstream infrastructure of BdThemes, a developer of premium WordPress web-design tools, and modified a remote JSON feed delivered to administrators' browsers to create rogue admin accounts. [...]

The maximum-severity vulnerability, which still has no CVE, allows malicious, remote administrator access to the business-analytics platform and its downstream users.

OpenAI has developed a new model called "GPT 5.6 Cyber," designed for vulnerability research, penetration testing, incident response, and remediation. [...]

It's time to turn from CVSS-backed patching to choke-point patching focused on breaking chains to critical assets.

A financially motivated threat actor previously associated with the Medusa ransomware operation is now deploying a new ransomware strain called StormEncryptor. [...]

Sophisticated iPhone exploit chains previously limited to nation-states are spreading far and wide to organized cybercrime groups.

Microsoft has disclosed that Storm-1175, a financially motivated threat actor linked to China, has deployed a previously undocumented ransomware strain called StormEncryptor. The use of StormEncryptor marks a shift from the adversary's previous use of Medusa ransomware, the Microsoft Threat Intelligence Team said. "StormEncryptor is written in C++ and appends the file name extension .encrypted

A public policy expert mapped global cybercrime laws to develop a five-point framework for protecting ethical hackers and good-faith security research.

The crime solver wore disguises, spied on targets, and built intelligence networks long before modern-day tactics emerged. He has lessons for today’s ethical- and nonethical-hat hackers.

A lot of security problems still begin with someone doing a completely normal thing. Cloning a repo. Answering a call. Leaving a box exposed. Trusting the default. That pretty much covers the mood this week. Old bugs are back, supply chains are getting stranger, and some exploit paths are so short you wonder what was supposed to stop them in the first place. That’s only part of it. Here’s

CISA has confirmed that ransomware gangs have begun exploiting two recently patched SonicWall SMA1000 vulnerabilities, including a maximum-severity server-side request forgery (SSRF) flaw. [...]

AI is making phishing, credential theft, and social engineering faster and more efficient, while traditional trust signals such as passwords, MFA, IP reputation, and geolocation become easier to bypass. Specops explains why organizations are increasingly adding device trust to their Zero Trust strategies. [...]

North Korea's state hackers are no longer content to type prompts into public chatbots. One of the country's main espionage groups has begun running artificial intelligence (AI) offline on its own servers, connecting document-search tools to files in its possession, and collecting the software parts needed to build AI into its malware. South Korean security firm Genians says it uncovered the
