Federal authorities recently dismantled a massive botnet—a network of hacked devices used in some of history’s largest online attacks, including record-setting distributed denial-of-service (DDoS) incidents. While the operation temporarily disrupted criminal activity, cybercriminals swiftly repurposed the now-unprotected devices to create an even stronger botnet, escalating the threat to businesses and internet infrastructure. Law enforcement agencies and tech companies now face the ongoing challenge of keeping pace with cyber attackers, as botnets continue to be used for extortion, business sabotage, and increasingly potent attacks on internet targets.
