Hackers believed to be Iranian have infiltrated a major Israeli internet company, which supplies dozens of vital companies with its services.
The "Black Shadow" group said that it had hacked the Israeli company Cyberserve, which is one of the largest Internet companies in Israel, according to the official Israeli channel Kan.
In a statement, the attackers said: "We have news for you. Certainly, you cannot connect to many sites today. We have attacked Cyberserve and its agents. You are wondering what about the information? As always we have a lot of it. If you don't want us to leak your information, contact us soon."
Among clients of Cyberserve company, which host several companies, are public transportation companies Dan and Kavim, the Moore Institute, and the Cancer Society.
The hackers published personal details of public transport company Kavim customers, including names, email addresses, and ID cards.
Cyberserve also said that a gay dating site had been hacked, saying, "We call on the National Cybersecurity Authority to act urgently to prevent information leakage," considering that "the leaking of users' personal information represents a psychological risk to them."
The hackers group, which the Israeli channel says is Iranian, published last March the personal data of customers of the Israeli car finance company KLS, which included photos of their identity cards and credit cards, and at that time the attackers demanded a ransom of ten Bitcoins.
A few months earlier, in December 2020, the "Black Shadow" group published customer account details for Israeli insurance company Sherbet, including ID cards, driver's licenses, payment receipts, medical documents, and photos of the company's employees.
Payment is not transferred within 1 day, the requested amount will be doubled.
