Microsoft released its Patch Tuesday, May 2021 with updates and security patches to fix 55 security flaws within Windows and other products. From these flaws, 4 are rated as critical and 3 are zero-day vulnerabilities.
In their Patch Tuesday of May 2021, three publicly-disclosed zero-day vulnerabilities were patched:
Underground marketplace pricing on RDP server access, compromised payment card data and DDoS-For-Hire services are surging.
Cybercriminals are vying for Remote Desktop Protocol (RDP) access, stolen payment cards and DDoS-for-Hire services, based on a recent analysis of underground marketplace pricing.
