From poisoned search results to GPU mining: A cryptojacking campaign abusing ScreenConnect and Microsoft .NET utilities

Microsoft Defender Experts identified an active cryptojacking campaign leveraging AI-assisted delivery mechanisms alongside traditional SEO poisoning. Attackers create fake download sites impersonating trusted utilities like CrystalDiskInfo, HWMonitor, and FurMark, targeting users with high-performance GPUs. Victims download ZIP archives containing legitimate executables bundled with malicious DLLs that establish persistence via ScreenConnect remote access tools. The operation employs sophisticated techniques including DLL sideloading, process hollowing into Microsoft-signed .NET binaries, and comprehensive defense evasion. Beyond cryptocurrency mining, the campaign establishes persistent remote access that could enable data theft, lateral movement, or ransomware deployment. The threat actors deliberately target PC enthusiasts and hardware-focused users most likely to own discrete GPUs suitable for profitable mining operations.

OPERATION SILENTCANVAS: JPEG BASED MULTISTAGE POWERSHELL INTRUSION

A sophisticated multi-stage intrusion campaign was identified leveraging a weaponized PowerShell payload disguised as a JPEG image file (sysupdate.jpeg) to deploy a trojanized ConnectWise ScreenConnect instance for covert remote access. The attack likely originates through social engineering techniques including phishing emails or malicious attachments. Upon execution, the malware establishes a staging environment, retrieves additional payloads from attacker-controlled infrastructure, and dynamically compiles a custom launcher using Microsoft's legitimate .NET compiler (csc.exe) to evade detection. The intrusion abuses ComputerDefaults.exe and a malicious ms-settings registry hijack to perform a fileless UAC bypass and obtain elevated privileges. Once elevated, the malware deploys a persistent service masquerading as OneDriveServers and launches a modified ScreenConnect framework capable of credential interception, remote command execution, surveillance operations, SYSTEM-level execution, encrypted command...

An unknown threat actor is abusing a remote management tool called #TiFLUX as an initial access vector, targeting a broad range of potential victims by email. The attacks using this Brasil-originated commercial utility began in February, but really ramped up in April and the beginning of this month.

The lures employ a variety of #spam tropes, including bogus event invitations and business invoices/bills.

TiFLUX seems uniquely vulnerable to this kind of abuse; The installer package also installs an old version of UltraVNC as well as a vulnerable #loldriver that can elevate privileges. Weirdest of all, the attackers are also using this RMM to deploy other heavily-abused RMMs, including #Splashtop and #ScreenConnect to the devices that get hit. Those RMMs are connecting to IP addresses associated with known bulletproof hosts.

Threat Actors Weaponize Tiflux RMMs in Malspam Attacks

Since late February, there has been an uptick in incidents involving Tiflux, a lesser-known Brazilian commercial remote management tool being weaponized by threat actors. The attack chain begins with phishing emails containing fake document lures that deliver a malicious MSI installer. Once executed, the installer deploys multiple remote access tools including UltraVNC, Splashtop, and ScreenConnect for persistent access. The Tiflux installer contains concerning components such as outdated VNC versions from 2014, expired certificates, hardcoded passwords, and a vulnerable HwRwDrv.sys driver known for privilege escalation abuse. The threat actors leverage these tools to establish persistence, capture screenshots, and collect system profiling information. This campaign exemplifies the continuing pattern of adversaries abusing legitimate remote management software for stealthy access to victim environments while chaining multiple tools together to maintain control.

CloudZ RAT potentially steals OTP messages using Pheno plugin

Cisco Talos uncovered an intrusion active since January 2026 where attackers deployed CloudZ remote access tool and an undocumented plugin called Pheno to steal credentials and one-time passwords. The attack exploits Microsoft Phone Link application by intercepting synchronized mobile data including SMS and OTPs without requiring phone-level infection. CloudZ evades detection through dynamic memory execution and anti-analysis checks. The infection chain begins with a fake ScreenConnect update executable, leading to a Rust-compiled dropper that deploys a .NET loader, ultimately establishing the modular CloudZ RAT. The Pheno plugin monitors Phone Link processes and intercepts SQLite database files containing synchronized phone data. CloudZ employs ConfuserEx obfuscation, multiple configuration layers, and facilitates various commands including browser data exfiltration, shell execution, and plugin management while maintaining persistence through scheduled tasks.

CloudZ RAT potentially steals OTP messages using Pheno plugin

Cisco Talos uncovered an intrusion active since January 2026 where attackers deployed CloudZ remote access tool and an undocumented plugin called Pheno to steal credentials and one-time passwords. The attack exploits Microsoft Phone Link application by intercepting synchronized mobile data including SMS and OTPs without requiring phone-level infection. CloudZ evades detection through dynamic memory execution and anti-analysis checks. The infection chain begins with a fake ScreenConnect update executable, leading to a Rust-compiled dropper that deploys a .NET loader, ultimately establishing the modular CloudZ RAT. The Pheno plugin monitors Phone Link processes and intercepts SQLite database files containing synchronized phone data. CloudZ employs ConfuserEx obfuscation, multiple configuration layers, and facilitates various commands including browser data exfiltration, shell execution, and plugin management while maintaining persistence through scheduled tasks.
