Ukraine grocery chain ATB confirms cyberattack as hackers threaten to leak data

What happened

Ukraine’s largest grocery store chain, ATB, confirmed that it was hit by a cyberattack after hackers posted an extortion demand on its website. The hacker group DataSuckers claimed responsibility for the attack and demanded $400,000, threatening to publish data it claimed to have stolen from millions of ATB customers.

A countdown timer for the ransom demand appeared on the retailer’s website but was later removed. The website was unavailable at the time of writing.

ATB denied that customer data had been compromised. The company temporarily took some online services offline for what it described as technical maintenance.

“The temporary message displayed on the website did not affect the security of your data,” ATB said . “The website remains fully under ATB’s control, and all information is securely protected.”

In response to ATB’s statement, the hackers published samples of the allegedly stolen data on their Telegram channel. They said they would not leak the entire database but would instead sell it “for a substantial amount.”
