Russian cyber threats and NATO’s Article 5. Conti says it’s going to bring Cost Rica to its knees. BLE proof-of-concept hack. CISA warns of initial access methods. Thanos proprietor indicted.

A recent assessment of the Russian cyber threat highlights the country's extensive cyber capabilities and potential to disrupt critical infrastructure. NATO's Article 5, which states that an attack on one member is considered an attack on all, has been applied to cyberspace, emphasizing the importance of collective cyber defense. The Conti ransomware attack against Costa Rica has spread in scope and effect, with the ransomware gang threatening to overthrow the new government and raising its demand to $20 million. Bluetooth vulnerabilities have been demonstrated in a proof-of-concept, affecting millions of cars, mobile devices, and locking systems. The Cybersecurity and Infrastructure Security Agency (CISA) and its international partners urge following best practices to prevent threat actors from gaining initial access. A hacker has shown a way to unlock Tesla models and start cars using a Bluetooth Low Energy (BLE) vulnerability. NCC Group has uncovered several BLE vulnerabilities that put millions of devices at risk. A technical advisory has been issued for Tesla, Kwikset/Weiser, and other BLE proximity authentication systems vulnerable to relay attacks. A U.S. attorney's office has charged a Venezuelan doctor for using and selling ransomware, and a ransomware mastermind has been identified for creating the "Thanos" ransomware builder.
