The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has ordered Federal Civilian Executive Branch (FCEB) agencies to strengthen asset lifecycle management for edge network devices and remove those that no longer receive security updates from original equipment manufacturers (OEMs) over the next 12 to 18 months. The agency said the move is to drive down technical debt and minimize the risk of compromise, as state-sponsored threat actors turn such devices as a preferred access pathway for breaking into target networks. Edge devices is an umbrella term that encompasses load balancers, firewalls, routers, switches, wireless access points, network security appliances, Internet of Things (IoT) edge devices, software-defined networks, and other physical or virtual networking components that route network traffic and hold privileged access. "Persistent cyber threat actors are increasingly exploiting unsupported edge devices -- hardware and software that no longer receiv...

A previously undocumented cyber espionage group operating from Asia broke into the networks of at least 70 government and critical infrastructure organizations across 37 countries over the past year, according to new findings from Palo Alto Networks Unit 42. In addition, the hacking crew has been observed conducting active reconnaissance against government infrastructure associated with 155 countries between November and December 2025. Some of the entities that have been successfully compromised include five national-level law enforcement/border control entities, three ministries of finance and other government ministries, and departments that align with economic, trade, natural resources, and diplomatic functions. The activity is being tracked by the cybersecurity company under the moniker TGR-STA-1030 , where "TGR" stands for temporary threat group and "STA" refers to state-backed motivation. Evidence shows that the threat actor has been active since January ...

As you know, enterprise network security has undergone significant evolution over the past decade. Firewalls have become more intelligent, threat detection methods have advanced, and access controls are now more detailed. However (and it’s a big “however”), the increasing use of mobile devices in business operations necessitates network security measures that are specifically tailored to their unique operating patterns. Yes, enterprises have invested heavily in robust network security such as firewalls, intrusion detection, and threat intelligence platforms. And yes, these controls work exceptionally well for traditional endpoints—but mobile devices operate differently! They connect to corporate Wi-Fi and public networks interchangeably. They run dozens of apps with varying trust levels. They process sensitive data in coffee shops, airports, and home offices. The challenge isn't that organizations lack security—it's that mobile devices need security con...

Cybersecurity researchers have discovered a new supply chain attack in which legitimate packages on npm and the Python Package Index (PyPI) repository have been compromised to push malicious versions to facilitate wallet credential theft and remote code execution. The compromised versions of the two packages are listed below - @dydxprotocol/v4-client-js (npm) - 3.4.1, 1.22.1, 1.15.2, 1.0.31  dydx-v4-client (PyPI) - 1.1.5post1 "The @dydxprotocol/v4-client-js (npm) and dydx-v4-client (PyPI) packages provide developers with tools to interact with the dYdX v4 protocol, including transaction signing, order placement, and wallet management," Socket security researcher Kush Pandya noted. "Applications using these packages handle sensitive cryptocurrency operations." dYdX is a non-custodial, decentralized cryptocurrency exchange for trading margin and perpetual swaps, while allowing users to retain full control over their assets. On its website, the DeFi exchang...

Artificial intelligence (AI) company Anthropic revealed that its latest large language model (LLM), Claude Opus 4.6, has found more than 500 previously unknown high-severity security flaws in open-source libraries, including Ghostscript , OpenSC , and CGIF . Claude Opus 4.6, which was launched Thursday, comes with improved coding skills, including code review and debugging capabilities, along with enhancements to tasks like financial analyses, research, and document creation. Stating that the model is "notably better" at discovering high-severity vulnerabilities without requiring any task-specific tooling, custom scaffolding, or specialized prompting, Anthropic said it is putting it to use to find and help fix vulnerabilities in open-source software. "Opus 4.6 reads and reasons about code the way a human researcher would—looking at past fixes to find similar bugs that weren't addressed, spotting patterns that tend to cause problems, or understanding a piece of...

The distributed denial-of-service ( DDoS ) botnet known as AISURU/Kimwolf has been attributed to a record-setting attack that peaked at 31.4 Terabits per second (Tbps) and lasted only 35 seconds. Cloudflare, which automatically detected and mitigated the activity, said it's part of a growing number of hyper-volumetric HTTP DDoS attacks mounted by the botnet in the fourth quarter of 2025. The attack took place in November 2025. AISURU/Kimwolf has also been linked to another DDoS campaign codenamed The Night Before Christmas that commenced on December 19, 2025. Per Cloudflare, the average size of the hyper-volumetric DDoS attacks during the campaign was 3 billion packets per second (Bpps), 4 Tbps, and 54 requests per second (Mrps), with the maximum rates touching 9 Bpps, 24 Tbps, and 205 Mrps. "DDoS attacks surged by 121% in 2025, reaching an average of 5,376 attacks automatically mitigated every hour," Cloudflare's Omer Yoachimik and Jorge Pacheco said. "In...

This week didn’t produce one big headline. It produced many small signals — the kind that quietly shape what attacks will look like next. Researchers tracked intrusions that start in ordinary places: developer workflows, remote tools, cloud access, identity paths, and even routine user actions. Nothing looked dramatic on the surface. That’s the point. Entry is becoming less visible while impact scales later. Several findings also show how attackers are industrializing their work — shared infrastructure, repeatable playbooks, rented access, and affiliate-style ecosystems. Operations are no longer isolated campaigns. They run more like services. This edition pulls those fragments together — short, precise updates that show where techniques are maturing, where exposure is widening, and what patterns are forming behind the noise.

Today’s “AI everywhere” reality is woven into everyday workflows across the enterprise, embedded in SaaS platforms, browsers, copilots, extensions, and a rapidly expanding universe of shadow tools that appear faster than security teams can track. Yet most organizations still rely on legacy controls that operate far away from where AI interactions actually occur. The result is a widening governance gap where AI usage grows exponentially, but visibility and control do not.  With AI becoming central to productivity, enterprises face a new challenge: enabling the business to innovate while maintaining governance, compliance, and security.  A new Buyer’s Guide for AI Usage Control argues that enterprises have fundamentally misunderstood where AI risk lives. Discovering AI Usage and Eliminating ‘Shadow’ AI will also be discussed in an upcoming virtual lunch and learn .  The surprising truth is that AI security isn’t a data problem or an app problem. It’s an interaction pro...

The elusive Iranian threat group known as Infy (aka Prince of Persia) has evolved its tactics as part of efforts to hide its tracks, even as it readied new command-and-control (C2) infrastructure coinciding with the end of the widespread internet blackout the regime imposed at the start of January 2026. "The threat actor stopped maintaining its C2 servers on January 8 for the first time since we began monitoring their activities," Tomer Bar, vice president of security research at SafeBreach, said in a report shared with The Hacker News. "This was the same day a country-wide internet shutdown was imposed by Iranian authorities in response to recent protests, which likely suggests that even government-affiliated cyber units did not have the ability or motivation to carry out malicious activities within Iran." The cybersecurity company said it observed renewed activity on January 26, 2026, as the hacking crew set up new C2 servers, one day before the Iranian gov...

A new, critical security vulnerability has been disclosed in the n8n workflow automation platform that, if successfully exploited, could result in the execution of arbitrary system commands. The flaw, tracked as CVE-2026-25049 (CVSS score: 9.4), is the result of inadequate sanitization that bypasses safeguards put in place to address CVE-2025-68613 (CVSS score: 9.9), another critical defect that was patched by n8n in December 2025. "Additional exploits in the expression evaluation of n8n have been identified and patched following CVE-2025-68613," n8n's maintainers said in an advisory released Wednesday. "An authenticated user with permission to create or modify workflows could abuse crafted expressions in workflow parameters to trigger unintended system command execution on the host running n8n." The issue affects the following versions - <1.123.17 (Fixed in 1.123.17) <2.5.2 (Fixed in 2.5.2)

Cybersecurity researchers have disclosed details of an active web traffic hijacking campaign that has targeted NGINX installations and management panels like Baota (BT) in an attempt to route it through the attacker's infrastructure. Datadog Security Labs said it observed threat actors associated with the recent React2Shell ( CVE-2025-55182 , CVSS score: 10.0) exploitation using malicious NGINX configurations to pull off the attack. "The malicious configuration intercepts legitimate web traffic between users and websites and routes it through attacker-controlled backend servers," security researcher Ryan Simon said. "The campaign targets Asian TLDs (.in, .id, .pe, .bd, .th), Chinese hosting infrastructure (Baota Panel), and government and educational TLDs (.edu, .gov)." The activity involves the use of shell scripts to inject malicious configurations into NGINX, an open-source reverse proxy and load balancer for web traffic management. These "locatio...

Microsoft on Wednesday said it built a lightweight scanner that it said can detect backdoors in open-weight large language models (LLMs) and improve the overall trust in artificial intelligence (AI) systems. The tech giant's AI Security team said the scanner leverages three observable signals that can be used to reliably flag the presence of backdoors while maintaining a low false positive rate. "These signatures are grounded in how trigger inputs measurably affect a model's internal behavior, providing a technically robust and operationally meaningful basis for detection," Blake Bullwinkel and Giorgio Severi said in a report shared with The Hacker News. LLMs can be susceptible to two types of tampering: model weights, which refer to learnable parameters within a machine learning model that undergird the decision-making logic and transform input data into predicted outputs, and the code itself. Another type of attack is model poisoning, which occurs when a t...
