Federal Communications Commission officials issued a warning Friday after detecting a surge in “one ring” scam robocalls with a West African area code.
Also known as “Wangiri,” Japanese for “one ring and drop,” the scam generates robocalls targeting specific area codes, often calling multiple times in the middle of the night. Generally, the robocaller will call a number and hang up after a ring or two. They may call repeatedly.
