KRVTZ-NET IDS alerts from February 2, 2026, report reconnaissance and early exploitation attempts targeting Fortigate VPN devices via CVE-2023-27997. The activity includes repeated GET requests to the /remote/logincheck endpoint, inbound requests to hidden environment files, and HTTP User-Agent scanning from known scanners like Censys. No active exploits are confirmed in the wild and no patches are currently available. The threat mainly affects organizations using Fortigate VPN appliances, with European countries such as Germany, France, the UK, Netherlands, Italy, Spain, Belgium, and Sweden at elevated risk. The threat is assessed as high severity due to potential impact and ease of exploitation despite low immediate risk. Mitigation involves enhanced network monitoring, access restrictions, IDS/IPS deployment, and proactive vulnerability management.

Threat actors associated with ShinyHunters-branded extortion operations are expanding their tactics, targeting cloud-based SaaS applications for data theft and extortion. The attackers use sophisticated voice phishing and credential harvesting to gain initial access, then exfiltrate sensitive data from various platforms. They employ aggressive extortion tactics, including harassment and DDoS attacks. The activity involves multiple threat clusters (UNC6661, UNC6671, UNC6240) and targets a growing number of cloud platforms. The attackers leverage social engineering to bypass MFA and use tools like ToogleBox Recall to cover their tracks. This activity highlights the effectiveness of social engineering and the importance of phishing-resistant MFA methods.
Charlie, one of our readers, has forwarded an interesting phishing email. The email was sent to users of the Vivladi Webmail service. While not overly convincing, the email is likely sufficient to trick a non-empty group of users:

A sophisticated multi-stage malware campaign employs living-off-the-land techniques and in-memory payload delivery to evade security controls. The infection chain begins with a hidden batch file that executes an embedded PowerShell loader, which then injects Donut-generated shellcode into legitimate Windows processes. The final payload is a heavily obfuscated .NET framework implementing advanced anti-analysis techniques, credential harvesting, surveillance capabilities, and remote system control. Data exfiltration occurs via Discord webhooks and Telegram bots. The malware, identified as Pulsar RAT, features live chat functionality and background payload deployment, demonstrating a modern, high-evasion Windows malware operation designed for long-term access and large-scale data theft.
The LABYRINTH CHOLLIMA threat group has split into three distinct adversaries: GOLDEN CHOLLIMA, PRESSURE CHOLLIMA, and core LABYRINTH CHOLLIMA. Each subgroup has specialized malware, objectives, and tradecraft. GOLDEN CHOLLIMA and PRESSURE CHOLLIMA focus on cryptocurrency entities, while core LABYRINTH CHOLLIMA continues espionage operations targeting industrial, logistics, and defense companies. Despite operating independently, these groups share tools and infrastructure, indicating coordinated resource allocation within North Korea's cyber ecosystem. The evolution stems from the KorDLL malware framework, which spawned several malware families. Recent operations demonstrate cloud-focused tradecraft and the use of zero-day vulnerabilities to deliver malware.
A multi-domain traffic distribution system (TDS) operation was discovered, centered around the domain toxicsnake-wifes.com. The infrastructure serves as a commodity cybercrime TDS farm, routing victims to phishing, scams, or malware payloads. The operation uses a first-stage JavaScript loader, followed by a second-stage that attempts to fetch upstream payloads. The cluster shares common WHOIS, DNS, and hosting patterns, indicative of bulletproof VPS usage. Multiple burner domains with similar tradecraft were identified, suggesting an organized operator cluster. The infrastructure employs obfuscation, dynamic remote injection, and disposable registration techniques. While the main payload was unreachable during analysis, historical evidence suggests the delivery of malicious content.
IClickFix is a malicious framework that compromises WordPress sites to distribute malware using the ClickFix social engineering tactic. Active since December 2024, it has infected over 3,800 WordPress sites globally. The framework injects malicious JavaScript into compromised sites, leading users through a fake CAPTCHA challenge that tricks them into executing malicious code. This ultimately installs NetSupport RAT, granting attackers full control of infected systems. The campaign has evolved over time, adding traffic distribution systems and refining its lures. While initially distributing Emmenhtal Loader and XFiles Stealer, it now primarily delivers NetSupport RAT. The widespread nature of the attacks suggests opportunistic exploitation rather than targeted campaigns.
A suspected state-affiliated threat actor has been targeting Kazakh and Afghan entities in a persistent campaign since at least August 2022. The attackers use a Windows-based RAT called KazakRAT, which allows for payload downloads, host data collection, and file exfiltration. The malware is delivered via .msi files and persists using the Run registry key. C2 communications are unencrypted over HTTP. The campaign also utilizes modified versions of XploitSpy Android spyware. Multiple KazakRAT variants have been observed with minor command-set changes. Victim targeting includes government and financial sector entities, particularly in Kazakhstan's Karaganda region. The operation shows low sophistication but high persistence, with similarities to APT36/Transparent Tribe activities.
A new Android trojan, named NFCShare, has been discovered targeting Deutsche Bank customers through a phishing campaign. The malware, disguised as a banking app update, prompts users to perform a fake card verification process. It exploits NFC technology to steal card data and PINs, which are then exfiltrated to a remote WebSocket endpoint. The trojan's distribution, user flow, and technical analysis are detailed, including its NFC reading capabilities and string obfuscation techniques. The malware shows links to Chinese-linked tooling and similarities to other NFC-based threats. IOCs include hashes, package details, and network indicators.
