Not long ago, security analysts from Huntress spotted someone tied to the Crazy ransomware group using standard employee surveillance and remote assistance programs. This person used common system tools – not custom malware – to stay hidden within company networks. Instead of flashy attacks, they moved quietly through digital environments already familiar to IT teams. What stands out is how ordinary software became part of a stealthy buildup toward data encryption. Behind the scenes, attackers mimic regular maintenance tasks to avoid suspicion. Their method skips complex hacking tricks in favor of blending in. Over time, such tactics make detection harder since alerts resemble routine actions. Rather than breaking in, they act like insiders who belong. Recently, this approach has become more frequent across different cybercrime efforts. Normal-looking tool usage now masks malicious goals deep inside infrastructure.
Throughout several cases reviewed by Huntress, Net Monitor for Employees Professional appeared next to SimpleHelp’s remote access software. Using both together let attackers maintain ongoing, hands-on access to affected machines. This pairing lowered their chances of setting off detection mechanisms. Each tool played a role in staying under the radar.
A single instance involved deployment of surveillance software through Windows Installer by running msiexec.exe, enabling adversaries to pull the agent straight from the official provider site. With it active, complete remote screen access emerged alongside command launching, data movement, and live observation of machine activity – delivering control similar to admin privileges on compromised devices.
To tighten their hold, the hackers tried turning on the default admin account via “net user administrator /active:yes.” Another layer came when they pulled down SimpleHelp using PowerShell scripts. Files were hidden under names that looked real – some copied Visual Studio’s vshost.exe pattern. Others posed as OneDrive components, tucked inside folders like ProgramData.
Despite detection of a single remote component, operations persisted due to multiple deployment layers.
Occasionally, the SimpleHelp executable appeared under altered names, mimicking standard corporate software files. Observed by analysts, these changes helped it evade immediate recognition.
At times, Huntress noticed efforts aimed at weakening Microsoft Defender – achieved by halting and removing related system services – to limit detection on infected devices. One breach showed attackers setting up alert triggers inside SimpleHelp, activated whenever machines reached sites tied to digital currency storage or trading.
These triggers watched for terms linked to wallet providers, exchange portals, blockchain lookup tools, and online payment systems. Elsewhere, the surveillance tool logged mentions of remote access software like RDP, AnyDesk, TeamViewer, UltraViewer, and VNC, possibly to spot signs of IT staff or security teams logging into affected endpoints.
Despite just a single confirmed instance leading to Crazy ransomware activation, Huntress identified shared command servers and repeated file names like “vhost.exe.” These similarities point toward one actor behind both breaches.
Notably, infrastructure links emerged across incidents. One attack stood out in impact. Yet patterns in execution imply coordination. File artifacts matched closely. Operation methods showed consistency. The evidence ties the events together indirectly. Reuse of tools strengthens that view. Infrastructure overlap was clear. Execution timing varied. Still, the digital fingerprints align.
Not just one but two securi
