Businesses around the world rushed Saturday to contain a ransomware attack that has paralyzed their computer networks, a situation complicated in the US by offices lightly staffed at the start of the Fourth of July holiday weekend according to Fox News.
It’s not yet known how many organizations have been hit by demands that they pay a ransom in order to get their systems working again. But some cybersecurity researchers predict the attack targeting customers of software supplier Kaseya could be one of the broadest ransomware attacks on record.
It follows a scourge of headline-grabbing attacks over recent months that have been a source of diplomatic tension between US President Joe Biden and Russian President Vladimir Putin over whether Russia has become a safe haven for cybercriminal gangs.
On Saturday, US President Joe Biden said there would be a response if investigations determined the Kremlin was linked in any way.
Which companies were hit in this latest ransomware attack?
The Miami-based firm Kaseya said a broad array of small businesses — including in financial services, travel and leisure, and public agencies on all continents — were hit in this latest ransomware attack.
In Sweden, the grocery chain Coop said the vast majority of its 800 stores were closed on Sunday for a second day because their cash register software supplier was down. A pharmacy chain, a gas station chain, the state railway and the public broadcaster SVT were also compromised.
