Costa Rica’s national health service was hacked sometime earlier this morning by a Russian ransomware group known as Hive. The intrusion comes just weeks after Costa Rican President Rodrigo Chaves declared a state of emergency in response to a data ransom attack from a different Russian ransomware gang — Conti. Ransomware experts say there is good reason to believe the same cybercriminals are behind both attacks, and that Hive has been helping Conti rebrand and evade international sanctions targeting extortion payouts to cybercriminals operating in Russia.

But many government employees aren't issued an approved card reader device that lets them use these cards at home or remotely, and so turn to low-cost readers they find online. What could go wrong? Here's one example.

The U.S. Drug Enforcement Administration (DEA) says it is investigating reports that hackers gained unauthorized access to an agency portal that taps into 16 different federal law enforcement databases. KrebsOnSecurity has learned the alleged compromise is tied to a cybercrime and online harassment community that routinely impersonates police and government officials to harvest personal information on their targets.
