Sodin ransomware exploits Windows vulnerability and processor architecture

When Sodin (also known as Sodinokibi and REvil) appeared in the first half of 2019, it immediately caught our attention for distributing itself through an Oracle Weblogic vulnerability and carrying out attacks on MSP providers . In a detailed analysis, we discovered that it also exploits the CVE-2018-8453 vulnerability to elevate privileges in Windows (rare among ransomware), and uses legitimate processor functions to circumvent security solutions.
