The GhostClaw malware campaign has expanded its distribution methods beyond npm packages to include GitHub repositories and AI-assisted development workflows. The attackers impersonate legitimate tools and utilize multi-stage payloads to steal credentials and retrieve additional malicious code. The infection chain involves executing shell commands, presenting fake authentication prompts, and establishing persistence. The campaign leverages both manual installation through README instructions and automated AI-assisted workflows. Multiple GitHub repositories have been identified, all communicating with a common command-and-control infrastructure. This shift in tactics allows the attackers to target a broader range of victims, including developers and users of AI-assisted coding tools.

A sophisticated ransomware family called Yurei has emerged, targeting Windows systems with advanced encryption methods. It rapidly encrypts data using ChaCha20 and ECIES, appends .Yurei to files, and disables recovery options. The malware spreads via SMB shares, removable drives, and credential-based remote execution. It employs anti-forensics techniques, including log wiping and secure deletion. Yurei features double-extortion capabilities, threatening data leaks alongside ransom demands. Analysis suggests possible code reuse from the Prince ransomware. The ransomware's professional build, stealthy propagation, and high operational speed make it a significant threat designed for irreversible data compromise.

Inf0s3c Stealer is a sophisticated Python-based malware designed to collect system information and user data. It systematically gathers host identifiers, CPU information, network configuration, and captures screenshots. The malware enumerates running processes, generates directory views, and compiles stolen data into a password-protected archive for exfiltration. It employs various techniques for persistence, including injection into Discord and Windows Startup manipulation. The stealer targets sensitive information such as passwords, cookies, browsing history, and cryptocurrency wallets. It also implements anti-VM checks and can self-delete after execution. The analysis reveals similarities with other malware projects, suggesting potential for rapid iteration and wider distribution.

APT-C-53, also known as Gamaredon, is a Russian state-sponsored threat group active since 2013, targeting Ukrainian government and military entities. The group has upgraded its attack techniques, focusing on dynamic cloud-based C2 infrastructure and targeted delivery of cloud storage tools. In 2025, they conducted high-density intelligence theft activities against Ukrainian government agencies. The attack chain involves dynamic changes in infrastructure, abuse of Microsoft Dev Tunnels, and sophisticated data exfiltration techniques. The group employs white-listed domain camouflage, domain shadowing, and weaponization of cloud tunnel services to evade detection. Their data theft process includes registry-based persistence, multi-stage payload delivery via Cloudflare Workers, and exfiltration through legitimate cloud tools like Dropbox.

APT36, a Pakistan-based threat actor, is conducting a cyber-espionage campaign against Indian Government entities, targeting BOSS Linux systems with weaponized .desktop files. The group uses spear-phishing emails to deliver malicious payloads, exploiting the Linux environment to maintain persistent access and evade security controls. The campaign involves sophisticated tactics, including the use of custom malware, command and control servers, and data exfiltration techniques. The attackers leverage newly registered domains and employ various MITRE ATT&CK techniques to execute their operations. This activity demonstrates APT36's increasing sophistication and adaptability in targeting critical government infrastructure.

A JavaScript-based malware campaign has been discovered affecting compromised WordPress websites. The malware injects a fullscreen iframe that loads content from suspicious external domains, aiming to force users to view unsolicited content for ad fraud, traffic generation, or social engineering. The infection was found embedded in the WordPress wp_options database table, exploiting the WPCode plugin. The malicious script uses advanced evasion techniques like anti-debugging, function hijacking, and localStorage abuse. It selectively targets Windows users on specific browsers, displaying a fake Cloudflare CAPTCHA page that prompts users to run a suspicious PowerShell command. This attack not only intrudes on user experience but also poses significant security risks, potentially leading to system compromise and damage to website reputation.

APT36, a Pakistan-based threat actor, has launched a sophisticated cyber-espionage campaign targeting the Indian defense sector. The group has adapted its tactics to focus on Linux-based environments, particularly BOSS Linux, used by Indian government agencies. The attack involves phishing emails with a ZIP file containing a malicious .desktop file. When executed, it downloads a legitimate PowerPoint file as a decoy while simultaneously deploying a malicious ELF binary. This multi-stage approach aims to bypass user suspicion and evade traditional security measures. The campaign signifies an advancement in APT36's capabilities and poses an increased risk to critical government and defense infrastructure. Organizations using Linux-based systems are advised to implement robust cybersecurity controls and threat detection mechanisms to mitigate potential risks.
