Multi AV Scanner detection for submitted file
Suricata IDS alerts for network traffic
Windows shortcut file (LNK) starts blacklisted processes

Sigma detected: Powerup Write Hijack DLL
Suspicious powershell command line found
Switches to a custom stack to bypass stack traces
Tries to detect sandboxes and other dynamic analysis tools (process name or module or function)
Windows shortcut file (LNK) contains suspicious command line arguments
Contains functionality to access loader functionality (e.g. LdrGetProcedureAddress)
Contains functionality to call native functions
Contains functionality to query CPU information (cpuid)
Contains functionality to read the PEB
Contains long sleeps (>= 3 min)
Creates a DirectInput object (often for capturing keystrokes)
Creates a process in suspended mode (likely to inject code)

Detected TCP or UDP traffic on non-standard ports
Detected non-DNS traffic on DNS port
Detected potential crypto function
Detected suspicious crossdomain redirect
Drops PE files
Enables debug privileges
Found a high number of Window / User specific system calls (may be a loop to detect user behavior)
Found inlined nop instructions (likely shell or obfuscated code)
Found potential string decryption / allocating functions
IP address seen in connection with other malware
Installs a raw input device (often for capturing keystrokes)
JA3 SSL client fingerprint seen in connection with other malware
Launches processes in debugging mode, may be used to hinder debugging
May sleep (evasive loops) to hinder dynamic analysis
One or more processes crash
PE file contains sections with non-standard names
Queries disk information (often used to detect virtual machines)
Queries sensitive processor information (via WMI, Win32_Processor, often done to detect virtual machines)
Queries the volume information (name, serial number etc) of a device
Sample execution stops while process was sleeping (likely an evasion)
Sigma detected: Potential Binary Or Script Dropper Via PowerShell
Sigma detected: PowerShell Web Download
Sigma detected: Usage Of Web Request Commands And Cmdlets
Suricata IDS alerts with low severity for network traffic
Uses a known web browser user agent for HTTP communication

Rhadamanthys | According to PCrisk, Rhadamanthys is a stealer-type malware, and as its name implies - it is designed to extract data from infected machines.At the time of writing, this malware is spread through malicious websites mirroring those of genuine software such as AnyDesk, Zoom, Notepad++, and others. Rhadamanthys is downloaded alongside the real program, thus diminishing immediate user suspicion. These sites were promoted through Google ads, which superseded the legitimate search results on the Google search engine. |
