PrintNightmare

Just before the 4th of July long weekend, hackers were on the attack. On July 1, 2021, Microsoft released news of an active exploit impacting all Windows systems. This critical vulnerability, known as “PrintNightmare” (CVE-2021-1675) could have given an attacker full control of a Windows system (including the ability to deploy ransomware) if a user interacted with malicious code (via malicious attachment, web advertisement, webpage, etc.) that targeted the Printing Subsystem in Windows.
