Heights Finance is a U.S. consumer finance company that provides personal loans and related lending services, mainly to customers who may have limited access to traditional bank credit. It is part of Heights Finance […]
Varonis Threat Labs has disclosed three vulnerabilities in Microsoft Copilot Personal that it said could allow a single click on a crafted link to silently pull data from connected apps and other information available to the victim's Copilot session. The flaws, which the researchers collectively named CoSnitch, turn in part on an undocumented URL parameter that the assistant itself surfaced
Two critical vulnerabilities impacting MLflow, an open-source artificial intelligence (AI) platform, and FUXA, an open-source, web-based SCADA / HMI software built for operational technology (OT) and industrial automation, are witnessing malicious scanning and exploitation efforts. According to independent reports from watchTowr and VulnCheck, the vulnerabilities in question are as follows -
A custom Java web shell likely linked to the Clop ransomware gang was designed specifically for PTC Windchill and FlexPLM servers, with built-in features to decrypt credentials, enumerate file repositories, and steal files. [...]
MacSync Stealer rapidly rotates domains to evade detection, but its behavior remains consistent. Learn how Microsoft uncovered 30+ related domains using durable hunting pivots. The post Hunting MacSync Stealer infrastructure through behavioral pivots appeared first on Microsoft Security Blog.
Researchers tested 31 million patterns to disrupt surveillance AI, with promising results but significant gaps between simulation and real-world use. The Kansas City-based cybersecurity researcher Bill Swearingen spent the past year doing something that sounds almost too simple to work: printing patterns, watching cameras fail to detect them, and repeating. TechCrunch reports that after roughly […]
Since February, we’ve grown AWS Security Hub Extended from 14 curated partners across 9 categories to 23 partners across 10. At Black Hat this month, 14 of those partners were at the Amazon Web Services (AWS) booth demoing live. Four of those partners delivered theater talks and ten were featured on SecurityLive streaming. We hosted […]
A ransomware affiliate calling itself Ransom Busters has been spotted proactively sending emails to victim organizations and claims to delete stolen data from ransomware groups' servers in exchange for a fee ranging from $20,000 to $60,000. "In these messages, the third-party offers to help the victim recover from ransomware attack. This immediately stands out as anomalous," GuidePoint Research
The affected ministries — one responsible for urban development, construction and housing, and the other for mobility, transport, climate protection and the environment — have been isolated from government networks since Friday as a precaution.
The University of Texas at San Antonio, which serves 40,000 students across six campuses, said its IT team identified threat activity on its academic campus over the weekend and took some systems, including phones, offline in response.
The agency said the latest attack came amid preparations to select a manager for seized corporate rights in IDS Ukraine, one of the country’s largest producers of bottled mineral water and beverages.
Security controls can block a familiar attack method while missing quieter ways to achieve the same objective. Picus Security's Blue Report 2026 shows how prevention rates can vary dramatically by technique and why behavioral testing is needed to uncover those gaps. [...]
Written by: Alex Tselevich, Michael Maturi Introduction Adversarial misuse of AI has increased the risk of data theft and extortion events, because when proprietary source code is exposed, defenders must scramble to identify and patch vulnerabilities while attackers deploy machine-speed AI tools against them. By structuring the analysis process, enforcing skeptical validation steps, and injecting domain-specific human expertise directly into the pipeline, we’ve achieved a leap in efficacy. Comb…
The Python-based malware framework takes living-off-the-land tactics to a new heights of stealth, with a modular implant that steals credentials and achieves persistence.
A ransomware affiliate appears to be sidling up to victims with offers of aid, masking its true intention of diverting ransom payments.
You can’t patch everything. So what do you fix first? Findings in Q2 2026 have changed traditional answers.The latest Quarterly Threat Landscape Report from Rapid7 Labs shows vulnerability disclosures still surging while attackers use automation and AI-assisted tooling to compress the time between disclosure and exploitation. The gap that patch cycles were built to fill is closing. Speed and volume are overwhelming security teams that have relied on traditional patch cycles and reactive program…
Security researchers at Anthropic and Switzerland's EPFL have demonstrated that self-propagating payloads can spread from one artificial intelligence (AI) agent to the next through the editable system prompt files that autonomous agent harnesses use to carry state between sessions. The work, released as a preprint on August 10, 2026, tests the technique in a simulated six-agent coding
Cybersecurity researchers have disclosed details of a previously undocumented Python implant framework dubbed TWINLOOT.
