The Federal Bureau of Investigation (FBI) in the United States recently warned consumers against using USB ports for charging in public spaces such as airports, malls, and hotels, as attackers can "juice jack" data or insert malware into one’s phone or device for theft.
While the public service announcement released on Twitter was meant for Americans, many other countries, like the Philippines, also have public establishments with free charging stations as emergency assistance to consumers. The threat of a juice jack attack exists everywhere people plug their devices into untrusted ports, like in public charging stations.
