Phishing campaigns have been observed using URLs related to ScreenConnect to deliver remote monitoring and management (RMM) payloads. These phishing emails commonly impersonate DocuSign to lure victims into interacting with malicious links. The threat involves social engineering to distribute malware via phishing.

An active malware campaign is targeting Thailand's healthcare sector, including Ministry of Health personnel and affiliated organizations. The operation leverages healthcare-themed spear-phishing lures distributed through malicious RAR archives containing obfuscated batch scripts and executable payloads. The infection chain employs multiple stages of obfuscation, GitHub-hosted payload delivery, and persistence mechanisms. The final payload is a Python-based information stealer designed to harvest browser credentials, session data, and cookies, with exfiltration attempts through Telegram Bot API. The campaign demonstrates sophisticated tradecraft including Rouki-obfuscated batch loaders, Startup folder persistence, and bundled Python interpreters. Active operational window spans from April to June 2026, with all samples uploaded from Thailand.

A multinational law enforcement operation called Operation Endgame has successfully disrupted SocGholish, a malware framework operated by threat actor TA569 since 2017. The operation took down 106 servers and domains and remediated nearly 15,000 compromised WordPress websites. SocGholish uses fake browser update prompts on compromised websites to trick victims into downloading malicious JScript payloads, providing initial access to corporate networks for ransomware deployment and data breaches. Analysis revealed that 55% of Infoblox cloud customers were exposed to SocGholish in 2026, demonstrating widespread impact across multiple industries including government, education, and healthcare. The framework employs domain shadowing techniques and operates through a four-stage attack chain involving traffic acquisition, filtering, fake update lures, and on-device implant execution. SocGholish infrastructure has facilitated access for various ransomware families and has been extensively used by the notorious Evi...

SideCopy, also tracked as APT36 or Transparent Tribe, has launched a new attack campaign targeting Indian defense personnel using a fake 'Minutes Of Meeting' document as lure. The attack employs an identical playbook to previous operations: a double-extension Minutes Of Meeting.docx.lnk file executes a PowerShell stager (pdfdocs.bat) from a nested pdfdocs folder while displaying a clean decoy document. The chain deploys a Remote Access Trojan (pdfdocs) that establishes persistence through the HKCU Run key. The staged components demonstrate low detection rates at initial delivery, with the decoy document scoring 0/66, the stager 1/61, and only the final executable reaching 35/71 detections.

This analysis covers infostealer distribution trends observed during May 2026, based on automated collection systems and diagnostic logs. Distribution occurred primarily through illegal software disguised as cracks and keygens, as well as email campaigns. ACRStealer, Remus, and LummaC2 were most prevalent, with distribution via domains including Mediafire and AWS S3 buckets. Microsoft was the most impersonated company, followed by Auslogics and NVIDIA. EXE files represented 78.9% of execution types, while DLL side-loading accounted for 21.1%. macOS environments saw ClickFix techniques and malicious Bash scripts, with 142 scripts and 12 C2 domains identified. Email campaigns distributed AgentTesla and DarkCloud. Remus showed significant growth, comprising 36% of distributions. LummaC2 remained the most prevalent overall variant.

Global law enforcement, including agencies from the Netherlands, Canada, United States, and Germany, coordinated Operation Endgame to disrupt TA569, a prominent cybercriminal group tracked since 2018. The operation targeted SocGholish infrastructure, taking down over 100 servers and domains while remediating 14,971 compromised websites. TA569 pioneered web inject techniques using fake browser updates to distribute malware, often leading to ransomware attacks. The group compromised high-traffic websites across multiple industries, affecting millions of visitors globally. Their attack chains involved traffic distribution systems like Keitaro TDS and ParrotTDS, delivering GhoLoader payloads that could lead to ransomware deployment in enterprise environments. Law enforcement actions included server disruption and website disinfection, significantly impacting the threat actor's operations, infrastructure, and reputation within the cybercriminal ecosystem.

In March 2026, threat actors leveraged AI-powered website builders to create typosquatting domains impersonating a Brazilian bank. The campaign employed ClickFix techniques, presenting victims with fake CAPTCHA and BSOD screens to trick them into executing malicious PowerShell commands. This delivered SmartRAT, a PowerShell-based banking trojan with capabilities including encrypted C2 communications, remote control of screen/keyboard/mouse, credential theft through keylogging and banking overlays, and QR code interception for transaction fraud. The malware establishes persistence via scheduled tasks and Windows services, and targets Brazilian financial institutions, payment platforms, and cryptocurrency exchanges. The threat actors' C2 panel contained critical authentication flaws allowing client-side bypass, suggesting deployment without adequate security review.

A new campaign has been identified utilizing a valid digital signature from a Chinese technology company that remains unrevoked. The attack chain employs a dropper that retrieves an extension-based module list from command and control infrastructure. The malicious payloads exploit DLL Side-Loading techniques through a legitimate Tencent-signed executable to achieve code execution. The infrastructure includes Google Cloud Storage and a dedicated domain for command and control operations. Multiple components have been identified including an EXE dropper, DLL loader, DAT payload, and the legitimate Tencent executable used for side-loading purposes.

Multiple phishing campaigns are exploiting the FIFA World Cup 2026 event to target mobile users globally. These campaigns use typosquatting, institutional spoofing, and impersonation of major sports retailers to harvest credentials. A sophisticated recruitment fraud campaign also targets corporate Google Workspace accounts with an Adversary-in-the-Middle platform capable of bypassing MFA. Attack vectors include SMS, WhatsApp, and search engines, leveraging emotional urgency and ticket scarcity. This creates risks for enterprises as employees may access work resources via compromised personal devices.

On May 15, 2026, Huntress agents detected an intrusion where threat actors compromised a terminal server to stage a massive phishing campaign rather than deploy ransomware. The attacker used legitimate bulk email software (Gammadyne Mailer) with a project file named 'dracii' (Romanian for 'the devils') and six recipient lists containing 8,894,920 email addresses. Operating from Romanian IP addresses, the actor impersonated UK pharmacy chain Boots through a fake customer satisfaction survey designed to harvest personal and payment card data. The phishing kit was hosted on a compromised Bolivian government website (ipelc.gob.bo), which Huntress reported to Bolivia's national CSIRT. The campaign used direct-to-MX delivery to bypass mail relays, with the mailer configured to send from 666 threads simultaneously. Evidence suggests this Romanian operator has been running multiple UK-targeting campaigns since at least July 2025, rotating between retail, tax, and cryptocurrency themes.
