DeadLock Ransomware Uses Polygon Smart Contracts to Make Extortion Infra Harder to Disrupt

The ransomware group known as DeadLock has been observed using decentralized infrastructure to facilitate victim communications and data leak operations in a bid to improve operational resilience. "Its recovery ecosystem combines the Session messaging network with blockchain-backed services that store and deliver resources used throughout the extortion process," the Microsoft Threat Intelligence team said . The tech giant said it observed the ransomware being deployed by multiple threat actors, including an affiliate for Lynx and INC ransomware. DeadLock was first detected in July 2025, employing double extortion tactics to encrypt victim environments and apply pressure by threatening to publicly release exfiltrated data. As of this month, the group has claimed 96 victims , with most of them located in Italy, Spain, Poland, Türkiye, and the U.S. In an analysis published earlier this January, Singapore-headquartered Group-IB said the group has managed to keep a lowe...

OpenAI Launches GPT-5.6-Cyber with Reduced Safeguards for Exploit Development

OpenAI on Monday unveiled a new cybersecurity-focused model called GPT‑5.6‑Cyber that it said is focused on vulnerability research, penetration testing, and incident response. "Built on GPT‑5.6 Sol, it is trained to improve capabilities on several specialized cybersecurity tasks (e.g., finding zero-day vulnerabilities and developing exploit chains) and to reduce refusals for certain higher-risk, dual-use cyber tasks," OpenAI said . The artificial intelligence (AI) company said it's making GPT 5.6 Cyber available through Daybreak Red, a new tier that provides access to its purpose-trained cybersecurity models to other firms for authorized vulnerability research, exploit validation, and security testing. GPT-5.6-Cyber, a more cyber-permissive version of GPT-5.6 Sol, builds upon GPT‑5.5‑Cyber , which OpenAI released in June 2026. To measure the reduced rate of refusals provided by GPT‑5.6‑Cyber through Daybreak Red access, OpenAI said it created an internal evaluat...

A Malicious SIM Card Can Run Attacker Code Inside the Modems Behind Cellular IoT Devices

A malicious SIM card can order the device it sits in to run commands of the attacker's choosing. On the cellular modules built into electric-vehicle chargers, industrial routers, and car telematics units, that is enough to take the whole device over. Researchers at the University of Birmingham and the security firm Fuzzware tested 26 phones and cellular modules for the capability, found it switched on in 9 of them, and used it to run their own code on a commercial EV charger. Six of the eight cellular modules they tested accepted the command. Only 3 of 18 phones did: the OPPO Find X5, the OPPO Reno 14 F 5G, and the ASUS Zenfone 9. No iPhone or Pixel was among them. The exposure is in machine-to-machine hardware. Five of the six were Quectel parts, three of them pulled from an EV charger, an industrial router, and a car's telematics control unit. Knowing the victim's number is not enough: every attack starts with a hostile card already in the slot, swapped by hand,...

Mozilla Revokes Firefox and Thunderbird Linux Signing Key After Key Lands in Private Repo

Mozilla has scrapped the cryptographic key behind Firefox and Thunderbird downloads for Linux after an unencrypted copy of it was committed by mistake to one of the company's own private code repositories. That key is how a user, or a Linux distribution packaging the browser, confirms a downloaded Firefox tarball came from Mozilla and was not tampered with. That decision carries a cost for anyone who checks what they download: files signed with the old key stop verifying once a user imports the revocation. That covers older Firefox and Thunderbird downloads, not just future ones. Nothing so far points to anyone outside the company getting hold of the key. The repository was private, the browser maker says a review of available audit records turned up no sign of unauthorized access, and everyone who could see it already had legitimate access anyway. Mozilla revoked it regardless. Most Firefox and Thunderbird users need to do nothing. Two groups do. Anyone who checks signatu...

Researchers Built a Fake Crypto Startup and Hired Three Suspected North Korean IT Workers

Security researchers invented a cryptocurrency startup, advertised developer jobs, and hired three people they believe were North Korean operatives. Every virtual machine the company issued was recording. The onboarding paperwork is the part hiring teams can use. The first hire claimed to live in Pasadena, Texas, then sent a California driver's license and a New York bank account. The researchers said the image metadata showed it had been processed with Google Gemini. They also reported a SynthID watermark, the invisible marker Google embeds in images its AI tools create or edit. The second supplied a Texas license, a valid Social Security number, and a bank account in Kansas City. The third sent a New York license belonging to someone else, a genuine iPhone 15 photograph with the GPS coordinates stripped. A successful placement gives the operative a real employee account and real access to source code and internal systems. The July 31 joint alert says North Korean IT work...

Researchers Turn USB Auto-Install Into a Full SYSTEM Takeover on Windows 11

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 redirection is not allowed by default. Security researchers Alejandro Hernando and Borja Martinez described the technique in " Plug And Pwn: Weaponizing Windows PnP Auto-Install ," research prepared for DEF CON 34. They built tooling to emulate arbitrary USB devices and said that, under the required conditions, an unprivileged user can turn the PnP installation path into SYSTEM code execution. Microsoft's own driver documentation describes the underlying selection step: Windows receives hardware and compatible IDs for a device and uses them to find a matching driver package. A...

Malicious MCP Servers Can Split Instructions to Make AI Coding Agents Exfiltrate Secrets

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 the agent stitch them together and send the data back. The attack targets coding tools that connect to outside servers over the Model Context Protocol (MCP), the open standard that lets AI assistants call external tools. A malicious MCP server can put one fragment in a tool description and another in a tool result; some setups also support server-initiated sampling. MCP does preserve structured tool and result boundaries. But ASSET Research Group's tests show agents can still combine instructions across them in the same working context, so no single fragment has to contain the whole mal...

Gunra Ransomware Exploits Fortinet and Schneider Electric Flaws to Breach Networks

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 ransomware attacks causing disruption and harm to U.S. and international organizations," CISA Acting Executive Assistant Director for Cybersecurity, Chris Butera, said. Attacks deploying the ransomware have leveraged security flaws in internet-facing Schneider Electric PowerLogic P5 ( CVE-2024-5559 ) and Fortinet FortiOS and FortiProxy ( CVE-2025-24472 ) appliances to obtain initial access, and then deploy the Gunra ransomware as part of a double extortion model that combines data exfiltration and data encryption for maximum impact. Victims who refuse to pay up within five to sev...
