A Microsoft Teams voice-phishing campaign leveraging Quick Assist, a remote administration tool, was tracked in September 2025. The campaign uses help desk scams to gain initial access, followed by user group enumeration and the execution of a PowerShell script to download a command and control payload. The attack employs AMSI bypass, encrypted communications, and a web-socket remote access trojan. Multiple Microsoft 365 tenants with IT-related subdomains were used, along with various IPs and domains for C2 infrastructure. The campaign shows similarities to Storm-1811 and PhantomCaptcha activities, suggesting a complex cybercrime ecosystem. The attackers' ultimate goal may be ransomware deployment, although observed attempts were successfully blocked.

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:

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.
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.
RedKitten is a newly identified campaign targeting Iranian interests, first observed in January 2026. The malware uses GitHub and Google Drive for configuration and payload retrieval, and Telegram for command and control. It appears to exploit the Dey 1404 Protests in Iran, targeting organizations documenting human rights abuses. The threat actor rapidly built this campaign using AI tools, as evidenced by traces of LLM-assisted development. While attribution is not definitive, the activity aligns with Iranian state-sponsored attackers. The malware, dubbed SloppyMIO, can fetch modules, execute commands, collect files, and deploy additional malware with persistence.
