A warning to e-commerce sites, Conti ransomware gang squeezes Costa Rica and more
Welcome to Cyber Security Today. It’s Wednesday May 18th, 2022 I’m Howard Solomon, contributing reporter on cybersecurity for ITWorldCanada.com.
The Conti ransomware gang has increased pressure on Costa Rica to capitulate to its multi-million dollar financial demands. In a message Monday the gang claimed it is working with people inside the government. It also says it is trying to break into more IT systems and overthrow the government through cyber attacks. The Associated Press news agencies quotes experts as saying overthrowing the government isn’t likely the gang’s goal. But it does want to cause more disruption. The Conti gang began compromising government data in Costa Rica in April. The newly-elected government declared a state of emergency last week.
American authorities allege a heart doctor living in Venezuela is behind the use and sale of ransomware to cybercrooks. The man, who is also a citizen of France and Venezuela, faces American charges of conspiracy to commit computer intrusions and attempted computer intrusions if he is arrested and extradited to the U.S. He is allegedly behind the Jigsaw ransomware and the Thanos ransomware builder.

Finally, devices that use Bluetooth Low Energy technology for wirelessly unlocking doors in buildings, homes and cars can be hacked. That’s according to researchers at NCC Group. They say they have developed a tool for conducting a new type of relay attack that can bypass device defences. Their technique works against some models of Kwitkset home locks as well as Tesla Model 3 and Model Y cars that use a Bluetooth Low Energy mobile app or key fob. The researchers urge the BlueTooth Special Interest Group to warn manufacturers and buyers about the risks of this kind of relay attack. Companies using these kinds of smart locks might have to think about adding an additional entrance requirement such as a hand or fingerprint reader for doors with Bluetooth Low Energy fob access.
