Description

This encoder merely replaces the given payload with the EICAR test string.
Note, this is sure to ruin your payload.

Any content-aware firewall, proxy, IDS, or IPS that follows anti-virus
standards should alert and do what it would normally do when malware is
transmitted across the wire.
