XWorm

Score:	100
Range:	0 - 100
Confidence:	100%

Signatures

Antivirus / Scanner detection for submitted sample

Antivirus detection for dropped file

Found malware configuration

Malicious sample detected (through community Yara rule)

Multi AV Scanner detection for submitted file

Suricata IDS alerts for network traffic

Yara detected AntiVM3

Yara detected XWorm

.NET source code contains method to dynamically call methods (often used by packers)

.NET source code contains potential unpacker

.NET source code contains very large array initializations

.NET source code contains very large strings

.NET source code references suspicious native API functions

Allocates memory in foreign processes

C2 URLs / IPs found in malware configuration

Compiles code for process injection (via .Net compiler)

Injects a PE file into a foreign processes

Joe Sandbox ML detected suspicious sample

Queries sensitive video device information (via WMI, Win32_VideoController, often done to detect virtual machines)

Sample uses string decryption to hide its real strings

Sigma detected: Dot net compiler compiles file from suspicious location

Writes to foreign memory regions

AV process strings found (often used to terminate AV products)

Allocates memory with a write watch (potentially for evading sandboxes)

Binary contains a suspicious time stamp

Checks if Antivirus/Antispyware/Firewall program is installed (via WMI)

Checks if the current process is being debugged

Compiles C# or VB.Net code

Contains long sleeps (>= 3 min)

Creates a process in suspended mode (likely to inject code)

Detected TCP or UDP traffic on non-standard ports

Detected potential crypto function

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 large amount of non-executed APIs

IP address seen in connection with other malware

Internet Provider seen in connection with other malware

JA3 SSL client fingerprint seen in connection with other malware

May sleep (evasive loops) to hinder dynamic analysis

One or more processes crash

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

Sigma detected: Dynamic .NET Compilation Via Csc.EXE

Uses code obfuscation techniques (call, push, ret)

Yara signature match
