Swiss heavy equipment company Aebi Schmidt apparently was hit with a ransomware attack earlier this week.

The company has not issued a public report on the incident, but told TechCrunch that its Windows environment had been hit with malware and the company had shut down that portion of its network while it deals with the situation.

Aebi Schmidt employees had been sent home due to the attack, which was described as ransomware, TechCrunch reported, citing other sources at the company.

” It could be a nation-state, competitor, or someone trying to manipulate the stock price for financial gain. With ransomware attacks targeting manufacturing and critical infrastructure, the goal is more likely to cause disruption than to actually extract ransom payments. The political and financial damages from these attacks can be far greater,” said Saurabh Sharma, Virsec’s vice president.

If ransomware is behind this attack then Aebi Schmidt would be the latest big firm to have its operations disrupted, joining The Weather Channel and Norsk Hydro. The TV network was taken off the air for almost one hour earlier this week. The Norwegian aluminum maker was hit with LockerGoga ransomware in March shutting down a large portion of its operation and costing the company an estimated $40 million in damage.

SC Media has contacted Aebi Schmidt for additional information on the situation.
