The Attleboro, MA-headquartered company, whose products are used in a variety of contexts including electric vehicles, airplanes, renewable energy, and industrial equipment, actually mentioned the word “ransomware” in its Form 8-K. It’s a welcome rarity when it comes to cyber incident disclosures, although there is nothing on its website or social media pages highlighting the ongoing technical difficulties. In the form, Sensata confirmed its operations are temporarily affected, including “shipping, receiving, manufacturing production, and various other support functions.” … It sounds like a classic double extortion scenario: devices were encrypted, and evidence files were taken - though the full scope of that is still under review.
