As Americans prepare to hit the highways and airports this Thanksgiving holiday, CISA and the Federal Bureau of Investigation (FBI) are reminding critical infrastructure partners that malicious cyber actors aren’t making the same holiday plans as you. Recent history tells us that this could be a time when these persistent cyber actors halfway across the world are looking for ways—big and small—to disrupt the critical networks and systems belonging to organizations, businesses, and critical infrastructure.

CISA and the FBI strongly urge all entities–especially critical infrastructure partners–to examine their current cybersecurity posture and implement best practices and mitigations to manage the risk posed by cyber threats.

Remind employees not to click on suspicious links, and conduct exercises to raise awareness.

Unencrypted financial transactions.
