The correct statement is:
Payload free worms find networks to infect, while payload worms load themselves into memory.
Payload free worms are a type of malware that spread by exploiting vulnerabilities in computer networks to find new hosts to infect. Once they find a vulnerable host, they inject their code into the memory of the compromised system, allowing them to execute their malicious activities.
On the other hand, payload worms typically carry a specific payload or set of instructions that they deliver to the infected hosts. This payload can range from disrupting operations, stealing data, or providing a backdoor for remote control. Payload worms often propagate by self-replicating and exploiting vulnerabilities in networks or software systems.
In summary, the main difference lies in the behavior of the worms. Payload-free worms focus on infecting new hosts by finding vulnerable networks, while payload worms carry a specific payload that they deliver to compromised hosts, often for the purpose of control or disruption.
