A recently disclosed security flaw patched by Microsoft may have been exploited by the Russia-linked state-sponsored threat actor known as APT28 , according to new findings from Akamai. The vulnerability in question is CVE-2026-21513 (CVSS score: 8.8), a high-severity security feature bypass affecting the MSHTML Framework. "Protection mechanism failure in MSHTML Framework allows an unauthorized attacker to bypass a security feature over a network," Microsoft noted in its advisory for the flaw. It was fixed by the Windows maker as part of its February 2026 Patch Tuesday update. However, the tech giant also noted that the vulnerability had been exploited as a zero-day in real-world attacks, crediting the Microsoft Threat Intelligence Center (MSTIC), Microsoft Security Response Center (MSRC), and Office Product Group Security Team, along with Google Threat Intelligence Group (GTIG), for reporting it. In a hypothetical attack scenario, a threat actor could weaponize th...

OpenClaw has fixed a high-severity security issue that, if successfully exploited, could have allowed a malicious website to connect to a locally running artificial intelligence (AI) agent and take over control. "Our vulnerability lives in the core system itself – no plugins, no marketplace, no user-installed extensions – just the bare OpenClaw gateway, running exactly as documented," Oasis Security said in a report published this week. The flaw has been codenamed ClawJacked by the cybersecurity company. The attack assumes the following threat model: A developer has OpenClaw set up and running on their laptop, with its gateway , a local WebSocket server, bound to localhost and protected by a password. The attack kicks in when the developer lands on an attacker-controlled website through social engineering or some other means. The infection sequence then follows the steps below - Malicious JavaScript on the web page opens a WebSocket connection to localhost on the ...

New research has found that Google Cloud API keys, typically designated as project identifiers for billing purposes, could be abused to authenticate to sensitive Gemini endpoints and access private data. The findings come from Truffle Security, which discovered nearly 3,000 Google API keys (identified by the prefix "AIza") embedded in client-side code to provide Google-related services like embedded maps on websites. "With a valid key, an attacker can access uploaded files, cached data, and charge LLM-usage to your account," security researcher Joe Leon said , adding the keys "now also authenticate to Gemini even though they were never intended for it." The problem occurs when users enable the Gemini API on a Google Cloud project (i.e., Generative Language API), causing the existing API keys in that project, including those accessible via the website JavaScript code, to gain surreptitious access to Gemini endpoints without any warning or notice. Th...

The Shadowserver Foundation has revealed that over 900 Sangoma FreePBX instances still remain infected with web shells as part of attacks that exploited a command injection vulnerability starting in December 2025. Of these, 401 instances are located in the U.S., followed by 51 in Brazil, 43 in Canada, 40 in Germany, and 36 in France. The non-profit entity said the compromises are likely accomplished via the exploitation of CVE-2025-64328 (CVSS score: 8.6), a high-severity security flaw that could enable post-authentication command injection. "The impact is that any user with access to the FreePBX Administration panel could leverage this vulnerability to execute arbitrary shell commands on the underlying host," FreePBX said in an advisory for the flaw in November 2025. "An attacker could leverage this to obtain remote access to the system as the asterisk user." The vulnerability affects FreePBX versions higher than and including 17.0.2.36. It was resolved in...

Nothing here looks dramatic at first glance. That’s the point. Many of this week’s threats begin with something ordinary, like an ad, a meeting invite, or a software update. Behind the scenes, the tactics are sharper. Access happens faster. Control is established sooner. Cleanup becomes harder. Here is a quick look at the signals worth paying attention to.

The threat activity cluster known as UnsolicitedBooker has been observed targeting telecommunications companies in Kyrgyzstan and Tajikistan, marking a shift from prior attacks aimed at Saudi Arabian entities. The attacks involve the deployment of two distinct backdoors codenamed LuciDoor and MarsSnake, according to a report published by Positive Technologies last week. "The group used several unique and rare instruments of Chinese origin," researchers Alexander Badaev and Maxim Shamanov said . UnsolicitedBooker was first documented by ESET in May 2025, attributing the China-aligned threat actor to a cyber attack targeting an unnamed international organization in Saudi Arabia with a backdoor dubbed MarsSnake. The group is assessed to be active since at least March 2023 and has a history of targeting organizations in Asia, Africa, and the Middle East. Further analysis of the threat actor has uncovered tactical overlaps with two other clusters, including Space Pirates an...

Cybersecurity researchers have disclosed details of a new cryptojacking campaign that uses pirated software bundles as lures to deploy a bespoke XMRig miner program on compromised hosts. "Analysis of the recovered dropper, persistence triggers, and mining payload reveals a sophisticated, multi-stage infection prioritizing maximum cryptocurrency mining hashrate, often destabilizing the victim system," Trellix researcher Aswath A said in a technical report published last week. "Furthermore, the malware exhibits worm-like capabilities, spreading across external storage devices, enabling lateral movement even in air-gapped environments." The entry point of the attack is the use of social engineering decoys, advertising free premium software in the form of pirated software bundles, such as installers for office productivity suites, to trick unsuspecting users into downloading malware-laced executables. The binary acts as the central nervous system of the infectio...

The Iranian hacking group known as MuddyWater (aka Earth Vetala, Mango Sandstorm, and MUDDYCOAST) has targeted several organizations and individuals mainly located across the Middle East and North Africa (MENA) region as part of a new campaign codenamed Operation Olalampo . The activity, first observed on January 26, 2026, has resulted in the deployment of new malware families that share overlapping samples previously identified as used by the threat actor, according to a report published by Group-IB. These include downloaders like GhostFetch and HTTP_VIP, along with a Rust backdoor called CHAR and an advanced implant codenamed GhostBackDoor that's dropped by GhostFetch. "These attacks follow similar patterns and align with the killchains previously observed in MuddyWater attacks; starting with a phishing email with a Microsoft Office document attached to it that contains malicious macro code that decodes the embedded payload and drops it on the system and executes it, pro...

A Russian-speaking, financially motivated threat actor has been observed taking advantage of commercial generative artificial intelligence (AI) services to compromise over 600 FortiGate devices located in 55 countries. That's according to new findings from Amazon Threat Intelligence, which said it observed the activity between January 11 and February 18, 2026. "No exploitation of FortiGate vulnerabilities was observed—instead, this campaign succeeded by exploiting exposed management ports and weak credentials with single-factor authentication, fundamental security gaps that AI helped an unsophisticated actor exploit at scale," CJ Moses, Chief Information Security Officer (CISO) of Amazon Integrated Security, said in a report. The tech giant described the threat actor as having limited technical capabilities, a constraint they overcame by relying on multiple commercial generative AI tools to implement various phases of the attack cycle, such as tool development, attac...

Artificial intelligence (AI) company Anthropic has begun to roll out a new security feature for Claude Code that can scan a user's software codebase for vulnerabilities and suggest patches.
