Organizations across the country are on edge today after a flurry of phony bomb threats hit several public entities Thursday, such as universities, schools and news outlets, among others. The attackers distributed malicious emails claiming to have placed some type of explosive materials in the recipient’s building. The emails stated the attackers would detonate these explosives unless the victim made a Bitcoin payment of several thousand dollars.
Cisco Talos discovered that this campaign is actually an evolution of sextortion and extortion attacks that we reported on in October. The claims in the emails we’ve seen from this actor are completely false, yet they have caused untold amounts of damage as organizations have evacuated buildings and called upon law enforcement to investigate.
