Suricata IDS alerts for network traffic
Yara detected FormBook
.NET source code contains potential unpacker
AI detected suspicious sample
Adds a directory exclusion to Windows Defender
Allocates memory in foreign processes
Found direct / indirect Syscall (likely to bypass EDR)
Initial sample is a PE file and has a suspicious name
Injects a PE file into a foreign processes
Machine Learning detection for dropped file
Machine Learning detection for sample
Maps a DLL or memory area into another process
Performs DNS queries to domains with low reputation
Queues an APC in another process (thread injection)
Sigma detected: Powershell Base64 Encoded MpPreference Cmdlet
Tries to harvest and steal browser information (history, passwords, etc)
Tries to steal Mail credentials (via file / registry access)
Uses schtasks.exe or at.exe to add and modify task schedules
Writes to foreign memory regions
Allocates memory with a write watch (potentially for evading sandboxes)
Allocates memory within range which is reserved for system DLLs (kernel32.dll, advapi32.dll, etc)
Checks if the current process is being debugged
Connects to several IPs in different countries
Contains functionality for execution timing, often used to detect debuggers
Contains functionality to access loader functionality (e.g. LdrGetProcedureAddress)
Contains functionality to call native functions
Contains functionality to open a port and listen for incoming connection (possibly a backdoor)
Contains functionality to read the PEB
Contains long sleeps (>= 3 min)
Creates a process in suspended mode (likely to inject code)
Detected potential crypto function
Dropped file seen in connection with other malware
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 dropped PE file which has not been started or loaded
Found inlined nop instructions (likely shell or obfuscated code)
Found large amount of non-executed APIs
Found potential string decryption / allocating functions
IP address seen in connection with other malware
Internet Provider seen in connection with other malware
May sleep (evasive loops) to hinder dynamic analysis
PE / OLE file has an invalid certificate
PE file contains more sections than normal
PE file contains sections with non-standard names
Queries the volume information (name, serial number etc) of a device
Sample execution stops while process was sleeping (likely an evasion)
Sample file is different than original file name gathered from version info
Searches the installation path of Mozilla Firefox
Sigma detected: Powershell Defender Exclusion
Sigma detected: Suspicious Add Scheduled Task Parent
Sigma detected: Suspicious Schtasks From Env Var Folder
Uses 32bit PE files
Uses code obfuscation techniques (call, push, ret)
