Replicating malicious code, including viruses and worms, will attempt to attack other systems once it has successfully compromised the target system or the product.
How it's found
Replicating Malicious Code (Virus or Worm) is typically found by tracing untrusted input from where it enters the system to the point where it is used without the check or neutralization this weakness describes, combining manual code review with dynamic testing.
Consequences
- Execute Unauthorized Code or Commands
Mitigations
- Operation: Antivirus software scans for viruses or worms.
- Installation: Always verify the integrity of the software that is being installed.
