Hackers hijack web hosting service to extort customers

A cyberattack against Israel web hosting provider Cyberserve has disrupted several websites and could have serious repercussions thanks to attackers stealing sensitive personally identifiable information (PII) about its customers, some of which are not aligned with the views of the conservative country.

report on the development, BeepComputer said that the hacking group BlackShadow claimed responsibility for the attack.

According to The Times of Israelin the days leading up to the attack, the country’s National Cybersecurity Directorate had repeatedly warned CyberServe of an impending cyberattack.

Surprisingly, in addition to demanding money from CyberServe, BlackShadow allegedly also extorted the hosting provider‘s customers.

BeepComputer describes BlackShadow as an Iranian state-sponsored hacking group that has a history of attacking Israeli targets and has ties to Pay2Key Ransomware stump.

Although the band is reportedly claiming $1 million in cryptocurrency from Cyberserve, the threat actors behind BlackShadow would not be financially motivated.

Omri Segev Moyal, co-founder and CEO of Israel cyber security Profero firm, says BeepComputer that attacks by state-sponsored groups such as BlackShadow are retaliatory and designed to disrupt Israeli interests.

In typical ransomware fashion, BlackShadow immediately leaked a sample of a thousand records to prove they had exfiltrated the hosting provider’s customer data.

Although leaking PII can still lead to further attacks on those affected, including Identity theft, the situation here could be much more damaging. Indeed, the leaked data reportedly includes PII from a major Israeli LGBT site named Atrafwhich, in a conservative society, could have serious repercussions for those exposed.
