Hackers have attacked US company Kaseya to demand ransom from potentially over 1,000 companies through its software. Based in Miami, Kaseya offers IT tools to small and medium-sized businesses, including the VSA tool to manage their network of servers, computers and printers from a single source. It is difficult for the moment to estimate the extent of this attack. First direct consequence: the attack has already paralyzed 800 stores of Coop Sweden, one of the largest supermarket chains in the country, which had to suspend its activity on Saturday July 3.
Also called “ransomware”, this type of computer program exploits security holes in a company or an individual to cripple its computer systems and then demand a ransom to unlock them. Kaseya, who on Saturday called the cyberattack a “sophisticated”, ensures that it has been circumscribed “to a very small number of customers”.
Friday evening, the company explained that it had realized a possible incident on its VSA software at midday on the East American coast. The company then believed that “less than 40 customers worldwide” were affected. But the latter themselves provide services to other companies. According to the IT security company Huntress Labs, “more than 1,000 companies” were therefore affected.
