Among other targets, the cyberattack hit public transportation companies Dan and Kavim, which provide services in the Tel Aviv metropolitan area, the Holon City Children’s Museum and the public radio blog.
As of noon on Saturday, these web pages, all hosted by Cyberserve, were inaccessible.
“Black Shadow” also made available on Telegram, what it presented as the client file, which included names, emails and phone numbers of users of the Kavim company.
“The first data is there. If you do not contact us there will be more,” warned the group of hackers in a message that accompanies the alleged company file.
On Friday night, the hackers sent a message to Telegram alerting Cyberserve about their impending attack.
“We have news for you,” they wrote. “I probably won’t be able to log into many sites tonight and that’s because Cyberserve and its customers have been our target. And what about data? We have a lot,” they continued.
According to Israeli media citing experts, Black Shadow is an anti-Israel hacking group that uses cybercrime techniques for economic and ideological gain.
In March, they hacked KLS Capital, an Israeli financial company. In December 2020, the group also infiltrated the Israeli insurance company, Shirbit, stealing vast amounts of data from the company’s servers before demanding a ransom of almost a million dollars (864 million euros) and revealing of gradually a large amount of company data.
This criminal incursion this Saturday comes as Iran was also the target of an unprecedented cyberattack on Tuesday, which paralyzed fuel distribution across the country.
Although the perpetrators could not be identified, the Iranian agency Fars singled out opponents of the Iranian regime, Israel and the United States as suspects.
In September 2010, the Stuxnet virus hit Iran’s nuclear program, causing a series of errors in the centrifuges used for uranium enrichment.
From Stuxnet, Iran, on the one hand, and Israel and the United States, on the other, are frequently accused of cyberattacks.
