American Radio Relay League confirms $1 million ransom payment

The American Radio Relay League was hit by a sophisticated ransomware attack in mid-May that encrypted internal systems; ARRL negotiated and paid a $1 million ransom (largely covered by insurance) to obtain a decryptor and restore most systems. The organization indicated approximately 150 employees were affected, has implemented new infrastructure standards during restoration, and sources suggest the Embargo ransomware group may be responsible.
