Swiss rail vehicle manufacturer Stadler Rail says the Everest ransomware gang demanded about $12.3 million after breaching a data exchange platform shared with one of its suppliers.
The threat actor has not publicly claimed the attack, but the Swiss company says that it received an extortion letter from Everest ransomware asking for a ransom of 10 million Swiss francs.
The company responded by saying that it will not pay the threat actor and filed a criminal complaint with the Thurgau cantonal police.
"Stadler will not pay any ransom under any circumstances and is therefore not susceptible to extortion."
Stadler Rail is a large, multinational Swiss train manufacturer that builds locomotives, trams, metro trains, passenger trains, and railway signaling systems.
