Signatures

Antivirus detection for URL or domain

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 XWorm

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

.NET source code contains potential unpacker

.NET source code references suspicious native API functions

Allocates memory in foreign processes

C2 URLs / IPs found in malware configuration

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

Writes to foreign memory regions

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

Abnormal high CPU Usage

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)

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

Downloads executable code via HTTP

Enables debug privileges

Found a high number of Window / User specific system calls (may be a loop to detect user behavior)

HTTP GET or POST without a user agent

Internet Provider seen in connection with other malware

May sleep (evasive loops) to hinder dynamic analysis

Queries the volume information (name, serial number etc) of a device

Sample file is different than original file name gathered from version info

Suricata IDS alerts with low severity for network traffic

Yara signature match
