The U.S. Federal Bureau of Investigation (FBI) on Sunday stressed that the “magnitude” of the cyber-attack against the U.S. agency Casey could prevent all victims from responding individually since Friday.
Ahead of a long weekend in the United States, hackers attacked Kasia on Friday, demanding ransom money from more than 1,000 companies through its IT management software.
The FBI said in a statement on Saturday that it had “opened an investigation into its services” and was working with the U.S. Defense and Infrastructure Security Agency (CISA) and other agencies to “understand the scale of the threat.”
“If you believe your systems have been compromised, we encourage you to use all of the suggested actions, immediately shut down your servers (associated with hacked software) and follow Casey’s advice to report to the FBI,” U.S. Police said in a statement on Sunday.
“While the scale of the incident may prevent each victim from responding individually, all the information we receive will be useful in countering this threat,” the FBI added.
U.S. President Joe Biden said Saturday evening that he had ordered an investigation, specifically to determine whether the attack came from Russia or not.
For now, he said, “we’re not sure yet.”
It is difficult to estimate the extent of this attack by ransomware or “ransomware”, which disables a company’s computer systems and then demands a ransom to unlock them.
According to Kasaya, less than 40 customers have been affected. But some of them have multiple clients, and the attack can spread to hundreds or thousands.
In a new post on Sunday, the company said it was working around the clock to fix the problem and restore service “in all geographies”.
He hopes to be able to recover the business for customers who use his software remotely “within 24 to 48 hours” and continues to work on a solution for customers to use his software directly on their devices.
Computer security firm ESET Research on Saturday identified victims in 17 countries around the world.
The attack has already led to the temporary closure of several hundred stores of a major supermarket chain in Sweden on Saturday, with cash registers no longer operational.
