A stealth patch, also known as a silent update, is a security update that is applied to a software program without the user’s knowledge or consent. Stealth patches are often used to fix critical security vulnerabilities that could be exploited by attackers. Because they are applied without the user’s knowledge, stealth patches can be controversial, as they raise concerns about privacy and security.
There are a few different ways to check if a stealth patch has been applied to your system. One way is to check the software’s version number. If the version number has changed since you last checked, it is likely that a stealth patch has been applied. Another way to check for stealth patches is to use a security scanner. Security scanners can scan your system for known vulnerabilities and will often report if a stealth patch has been applied.
