This query was originally published in the threat analytics report, WinRAR CVE-2018-20250 exploit
WinRAR is a third-party file compressing application. Versions 5.61 and earlier contained a flaw that could be exploited by an attacker to read and write to an arbitrary path on the target's system. This could be used to run arbitrary code, overwrite system files, or access sensitive information. This vulnerability was designated CVE-2018-20250, and it is associated an outdated version of the legacy ACE compression library, 'unacev2.dll'.
The following query detects possible CVE-2020-20250 exploitation by looking for files created in the Startup folder.
