Malware Config
Signatures
- File and Directory Permissions Modification 1 TTPs 2 IoCs
Adversaries may modify file or directory permissions to evade defenses.
- Checks hardware identifiers (DMI) 1 TTPs 4 IoCs
Checks DMI information which indicate if the system is a virtual machine.
- Enumerates running processes
Discovers information about currently running processes on the system
- Reads MAC address of network interface 2 TTPs 2 IoCs
Fetches the MAC address of active network interfaces. May be used to detect known values for hypervisors.
- Checks CPU configuration 1 TTPs 1 IoCs
Checks CPU information which indicate if the system is a virtual machine.
- Reads CPU attributes 1 TTPs 50 IoCs
- Enumerates kernel/hardware configuration 1 TTPs 50 IoCs
Reads contents of /sys virtual filesystem to enumerate system information.
- Reads runtime system information 64 IoCs
Reads data from /proc virtual filesystem.
- System Network Configuration Discovery 1 TTPs 1 IoCs
Adversaries may gather information about the network configuration of a system.
- Writes file to tmp directory 1 IoCs
Malware often drops required files in the /tmp directory.
