Which malware type is capable of bypassing firewalls?

The statement that all types of malware can bypass firewalls is accurate because various forms of malware, including adware, spyware, and Trojans, can exploit different methods to circumvent firewall protections.

Adware may embed itself in seemingly legitimate software, making it difficult for firewalls to detect and block it as a malicious threat. This capability allows adware to pass through defenses, often leading to unwanted advertisements and tracking without triggering alerts.

Spyware, designed to collect sensitive information without the user's knowledge, can also find ways to penetrate firewall protections. It often disguises its traffic to blend in with regular network activity, which can result in it going undetected by firewalls.

Trojans are particularly notorious for bypassing firewalls because they masquerade as legitimate programs. Once a user is tricked into executing a Trojan, it can establish outbound connections for data exfiltration or control, effectively sidestepping firewall controls that would normally block unsafe applications.

Because each of these malware types utilizes distinctive tactics to avoid detection by firewalls, it supports the conclusion that all can potentially bypass these security measures.
