Invenergy, a US-based renewable energy company, has been hit by an attack, which the company confirmed in a statement issued on Friday.
Today, REvil, a notorious ransomware group, claimed responsibility for the attack.
Chicago-based Invenergy LLC launched an investigation after its systems were infiltrated and it noticed unauthorized activity. Invenergy said that it had not been affected by the attack and that it did not pay the ransom:
“At no time were Invenergy’s operations impacted, and no data was encrypted,” the company assured and added it “has not paid and does not intend to pay any ransom.”
REvil, which is a group of criminals known for carrying out high-impact ransomware attacks, claimed responsibility for the attack on Invenergy on its dark website. REvil claims to have obtained 4 terabytes of confidential information from Invenergy.
Among the data there are contracts and project details and “very personal and spicy” information on Invenergy’s chief executive officer, Michael Polsky. REvil says it has accessed personal emails, details about his divorce from his first wife, and compromising photos of him.
Polsky emigrated from Soviet Ukraine to the US in 1976 after building up a $1.5bn fortune. According to Forbes, his divorce from Maya was one of the most expensive in history after the couple split the money and assets acquired in marriage.
Besides Invenergy, REvil has recently hit meat-processing company JBS, a US Department of Energy contractor Sol Oriens, and Taiwanese Apple supplier Quanta.
