Cisco Systems has rolled out fixes for a critical security flaw affecting Redundancy Configuration Manager (RCM) for Cisco StarOS Software that could be weaponized by an unauthenticated, remote attacker to execute arbitrary code and take over vulnerable machines. Tracked as CVE-2022-20649 (CVSS score: 9.0), the vulnerability stems from the fact that the debug mode has…
An exploration of zero-click attack surface for the popular video conferencing solution Zoom has yielded two previously undisclosed security vulnerabilities that could have been exploited to crash the service, execute malicious code, and even leak arbitrary areas of its memory. Natalie Silvanovich of Google Project Zero, who discovered and reported the two flaws last year,…

Gone are the days when ransomware operators were happy with encrypting files on-site and more or less discretely charged their victims money for a decryption key. What we commonly find now is encryption with the additional threat of leaking stolen data, generally called Double-Extortion (or, as we like to call it: Cyber Extortion or Cy-X).…
Just as animals use their senses to detect danger, cybersecurity depends on sensors to identify signals in the computing environment that may signal danger. The more highly tuned, diverse and coordinated the senses, the more likely one is to detect important signals that indicate danger. This, however, can be a double-edged sword. Too many signals…

The coordinated cyberattacks targeting Ukrainian government websites and the deployment of a data-wiper malware called WhisperGate on select government systems are part of a broader wave of malicious activities aimed at sabotaging critical infrastructure in the country. The Secret Service of Ukraine on Monday confirmed that the two incidents are related, adding the breaches also…
Providing public Wi-Fi is a great service to offer your customers as it becomes more and more standard in today’s society. I like the fact that I do not have to worry about accessing the Internet while I am away, or spending a lot of money on an international connection, or just staying offline while…
