Summary: Diebold Nixdorf, the largest ATM provider in the United States with an estimated 35 percent of the worldwide cash machine market, discovered anomalous behavior on its corporate network on the evening of Saturday, April 25, and disconnected systems to contain a ransomware attack. The company said the incident did not affect ATMs, customer networks, or the general public, though sources told KrebsOnSecurity the response affected services for over 100 customers, and investigators found the intruders had installed ProLock ransomware.
Why it matters: The attackers struck on a Saturday evening, when technical staff are thinnest, and ProLock's current decryptor corrupts larger files such as databases, so paying the $175,000 to $660,000 ransom range BleepingComputer cites may not even restore the data.
