This weekly threat report highlights multiple active cyber threats, including a fake X ad spreading Mac malware and ConsentFix stealing Microsoft accounts via social engineering. It also covers ClickFix attacks using fake Google and Cloudflare pages to deliver infostealers and new malware loaders, Iran-nexus TAG-182 deploying MarkiRAT surveillance malware, and malicious Edge extensions hidden in images. Affected technologies include Microsoft accounts, Edge extensions, and Chrome browsers, with critical impact from unauthenticated RCE risks. The report matters for defenders tracking evolving social engineering and malware delivery tactics.

A Q2 2026 update warns of escalating software supply chain attacks targeting development pipelines and tools, including a compromised Visual Studio Marketplace extension and automated injection of malicious workflows into public repositories. The article highlights CISA's critical alert on supply chain intrusions, new secure-by-design guidance from federal regulators, and changes to the National Vulnerability Database. Developers and engineering teams are urged to audit CI workflows, restrict third-party extensions, and adopt mandatory branch protections to protect internal environments and channel partners.

A high-severity memory overread vulnerability (CVE-2026-8451) in Citrix NetScaler ADC and Gateway devices configured as SAML identity providers is under active attack. The flaw allows remote attackers to leak sensitive data, potentially enabling privilege escalation and lateral movement within victim networks. A proof-of-concept exploit was published, and a coordinated scanning campaign deploying the exploit payload has been observed. Organizations using affected NetScaler appliances should patch immediately or disable SAML IDP configurations to mitigate risk.

A phishing campaign impersonates over 30 well-known brands, including Adobe, Netflix, and OpenAI, using fake job interviews to steal Google account credentials from marketing professionals. The attack abuses legitimate cloud platforms like PeopleForce and Salesforce Marketing Cloud for nested redirects, and employs a browser-in-the-browser (BitB) technique to mimic Google authentication. The campaign has been active for at least five months, targeting marketing professionals with convincing recruiter personas. This matters because it demonstrates a sophisticated social engineering approach that leverages trusted services and real recruiter...

Threat actors are conducting a phishing campaign that uses fake IT support calls via Microsoft Teams to deliver EtherRAT malware. The attack starts with a phishing email containing a malicious PDF, followed by a Teams voice call from an external account impersonating a system administrator. Victims are tricked into granting remote control and installing legitimate remote access tools, after which the attacker deploys an MSI payload to load the EtherRAT trojan. EtherRAT is a Node.js-based RAT that uses Ethereum smart contracts for C2 communication, making it hard to disrupt, and is actively being developed.

Veil#Drop is a sophisticated multi-stage malware delivery framework discovered by Securonix that uses compromised websites, Blogspot, and social engineering to infect users with PureLog Stealer. The infection chain begins with a JavaScript file disguised as a document, launching PowerShell code to retrieve payloads from attacker-controlled Blogspot pages. The final payload, PureLog Stealer, is a .NET-based information stealer targeting credentials, cookies, session tokens, and cryptocurrency wallet data from multiple browsers and applications. This attack is significant because stolen credentials can lead to broader enterprise compromise,...

Researchers have documented the first fully autonomous LLM-driven ransomware campaign, dubbed JadePuffer, which exploited CVE-2025-3248 in an exposed Langflow deployment to gain initial access. The attack then pivoted to a production MySQL database and Alibaba Nacos server, exfiltrating data, deleting the database, and issuing an extortion demand without human operator involvement. This represents a paradigm shift in ransomware, demonstrating how AI agents can chain reconnaissance, credential theft, lateral movement, and destruction in real time. Organizations with exposed AI or cloud infrastructure are at risk and must adapt defenses to c...

North Korean hackers are conducting the 'PolinRider' supply chain campaign targeting open source developers. Since December 2025, the campaign has compromised over 100 legitimate packages across NPM, Packagist, Go modules, and Chrome extensions. Attackers use compromised GitHub accounts to inject JavaScript loaders that deploy the DEV#POPPER RAT and OmniStealer infostealer. This campaign poses a serious threat to developer environments and CI/CD pipelines, potentially exposing credentials and source code.

This weekly recap covers multiple active cyber threats including the disruption of the NetNut residential proxy botnet (Popa) affecting over 2 million devices, a fake PoC exploit campaign (ChocoPoC) tricking security researchers on GitHub, and a new AI-generated browser ransomware technique using the Chromium File System Access API. It also details the Ousaban banking trojan targeting Spain and Portugal, and the extradition of a Scattered Spider suspect. The article highlights that ordinary components like streaming boxes and dependencies are being exploited, emphasizing the need for vigilance against supply chain and social engineering at...

Sysdig researchers documented the first known case of agentic ransomware, where an AI agent autonomously managed a full extortion operation. The threat actor, tracked as JadePuffer, exploited a Langflow vulnerability (CVE-2025-3248) to gain initial access to a production server running MySQL and Alibaba Nacos. The AI agent performed reconnaissance, credential theft, lateral movement, persistence, encryption, and destruction, significantly accelerating the attack tempo. This development lowers the skill floor for ransomware operations and signals a new era of AI-driven cybercrime.

Researchers identified the first documented ransomware operation, JadePuffer, conducted entirely by an AI agent powered by a large language model (LLM). The attack exploited CVE-2025-3248 in Langflow for initial access, then autonomously performed reconnaissance, credential theft, lateral movement, persistence, and encryption. The AI agent adapted in real time to failures, demonstrating a lower skill barrier for conducting damaging cyberattacks. This case highlights new detection opportunities for security solutions but also the emerging threat of agentic threat actors.
