HoneyMyte APT group (also known as Mustang Panda) has significantly upgraded its CoolClient backdoor with kernel-level rootkit capabilities. The latest variant deploys a signed kernel-mode driver (msagent.sys) as a Windows service, enabling advanced stealth features including process hiding, file and registry protection, and network traffic filtering. The multi-stage malware uses DLL sideloading through a legitimate Sangfor application, establishes persistence via scheduled tasks and AutoRun entries, and implements UAC bypass techniques. CoolClient now injects into synchost.exe and communicates with the kernel driver through IOCTL requests. The driver hooks Nsiproxy to filter C2 addresses from network information. Victims have been identified in Myanmar, Mongolia, Pakistan, and Russia, with PlugX serving as the initial infection vector before CoolClient deployment.

Between late April and mid-June 2026, Microsoft observed heightened ACR Stealer activity targeting enterprise environments through ClickFix social engineering lures. This information-stealing malware, associated with Amatera Stealer rebranding and offered as malware-as-a-service, deployed through two distinct campaigns. The first utilized WebDAV-delivered payloads with Python loaders and blockchain-based command-and-control resolution. The second employed a fileless approach using MSHTA and steganography-concealed payloads within images. Both campaigns harvested browser credentials, authentication tokens, and sensitive documents from compromised systems. Threat actors leveraged obfuscated PowerShell scripts, scheduled task persistence, and in-memory execution techniques to evade detection. Notable tactics included masquerading as legitimate software updates, utilizing Windows DPAPI for credential decryption, and targeting PDF and Microsoft 365 documents. The blockchain dead-drop technique enabled dynamic i...

Kratos is a mature Phishing-as-a-Service operation targeting Microsoft 365 users across the United States, Europe, and other regions. The platform enables attackers to steal credentials through trusted platforms, anti-bot verification, and convincing login pages. Researchers traced three generations of the kit and uncovered 1,484 previously unattributed detonations. The operation targets organizations across more than 20 countries with particularly strong concentration in the US, Spain, and Southern Europe. Kratos includes an operator panel allowing deployment of phishing domains, configurable Telegram or email delivery, geographic restrictions, and multiple anti-bot systems. The kit has evolved through three page generations (V0, V1, V2) with different exfiltration code. Activity has been visible since January 2026, with the operator panel active since September 2025.

NightSpire ransomware, first discovered in February 2025, presents a categorization challenge regarding whether it operates as Ransomware-as-a-Service (RaaS). Analysis of two incidents from December 2025 and March 2026 reveals significant variations in tactics, techniques, and procedures between attacks. The March 2026 incident involved threat actors installing Chrome Remoting Desktop and AnyDesk for persistence, using Everything and 7Zip for data staging, MEGASync for exfiltration, and deploying VMWare Workstation and WPS Office. The attacker accessed systems via RDP days before detection. Comparison with the December 2025 incident shows evolution in the ransomware encryptor, including modified ransom note filenames and contents. These variations in TTPs and indicators suggest either operational evolution or involvement of multiple affiliates, demonstrating that ransomware indicators aren't consistent across campaigns.

TeamPCP has launched a supply chain attack targeting LiteLLM, an open-source Python library used in 36% of cloud environments. Malicious versions 1.82.7 and 1.82.8 were published on PyPI, employing sophisticated techniques for payload delivery and persistence. The compromised packages exploit Python's .pth mechanism for stealthy execution across any Python process. The malware collects sensitive data including API keys, cloud credentials, and CI/CD secrets, encrypting and exfiltrating them to attacker-controlled domains. This attack follows TeamPCP's previous compromises of Aqua Security's Trivy and Checkmarx tools, highlighting an ongoing campaign against the open-source ecosystem. The incident underscores the potential for widespread impact and the need for vigilance in software supply chain security.

A deceptive website impersonating CleanMyMac tricks users into installing SHub Stealer, a sophisticated macOS malware. The malware steals sensitive data, including passwords, browser data, cryptocurrency wallets, and Telegram sessions. It can also modify wallet apps to steal recovery phrases. The attack begins with users pasting a command into Terminal, which downloads and executes a malicious script. The malware performs extensive data collection from various browsers and wallet applications, and installs persistent backdoors in certain crypto wallet apps. SHub Stealer is part of a growing family of AppleScript-based macOS infostealers, demonstrating increasing sophistication in targeting Mac users.

The ongoing conflict in the Middle East has triggered a surge in cybercriminal activity. Over 8,000 newly registered domains with conflict-related keywords have been identified, many of which may be weaponized in future campaigns. Multiple cases of malicious activity have been observed, including targeted attacks using conflict-themed lures, deployment of the LOTUSLITE backdoor, fake news blogs leading to StealC malware, phishing sites impersonating government portals, donation scams, fraudulent storefronts, and meme-coin pump-and-dump schemes. Threat actors are leveraging various techniques such as DLL sideloading, shellcode execution, and social engineering to compromise victims. The campaigns demonstrate the opportunistic nature of cybercriminals in exploiting geopolitical events for malicious purposes.

A new hacking group called Punishing Owl has emerged, targeting Russian critical infrastructure. Their first attack on December 12, 2025, compromised a Russian state security agency, leaking internal documents. The group used DNS manipulation, created fake subdomains, and sent phishing emails to the victim's partners. They employed a PowerShell stealer called ZipWhisper to exfiltrate browser data. Punishing Owl's attacks are politically motivated and focus exclusively on Russian targets, including government agencies, scientific institutions, and IT organizations. The group has established a presence on cybercriminal forums and social media, likely operating from Kazakhstan. Experts predict this group will continue to be a persistent threat in the Russian cyberspace.

A massive malware campaign dubbed ClawHavoc has been uncovered in the ClawHub marketplace, targeting OpenClaw bots and their users. An AI bot named Alex, working with security researcher Oren Yomtov, discovered 341 malicious skills, including 335 from a single campaign. The malware, identified as Atomic Stealer (AMOS), uses sophisticated techniques to evade detection and steal sensitive data. The attack exploits users' trust in AI assistants, potentially compromising personal and financial information. In response, a new tool called Clawdex has been developed to help bots and users scan for malicious skills before installation.

PurpleBravo, a North Korean state-sponsored threat group, targets software developers through fake recruitment efforts, particularly in cryptocurrency and software development sectors. Their toolkit includes BeaverTail, PyLangGhost, and GolangGhost, designed for stealing browser credentials and cryptocurrency information. The group has affected 3,136 IP addresses, mainly in South Asia and North America, compromising 20 organizations across various industries. PurpleBravo's tactics include using fictitious personas, malicious GitHub repositories, and sophisticated malware to infiltrate IT services companies, posing a significant supply-chain risk. The group shows overlap with PurpleDelta, another North Korean threat actor, sharing infrastructure and operational patterns. PurpleBravo's focus on the IT sector in South Asia presents an overlooked threat to organizations outsourcing IT services.
