Storm Watch | Cyber News | MGM Data Breach, Jupyter Notebooks, Netscaler

Summary: This Storm Watch episode covers the takedowns of the Trigona ransomware group by the Ukrainian Cyber Alliance and of RagnarLocker, while noting that ransomware attacks often continue in new forms and that rising Bitcoin value tends to correlate with more attacks. The hosts also discuss vulnerabilities in Cisco routers and Citrix systems, criticize Cisco's disclosure and patching process, and examine the Okta breach, which occurred via access to support systems and compromised session tokens and HAR files.

What you should know: Two ransomware groups were taken down, yet the hosts note attacks often continue in new forms and that rising Bitcoin value correlates with more ransomware activity - so a takedown headline is not a reduction in your exposure. The Okta breach turned on compromised session tokens and HAR files, which the hosts stress are highly sensitive.
