Shimming is still a common technique used in the security industry in 2023. It involves inserting a thin piece of material, such as metal or plastic, between two objects to change the space between them. This is used to bypass security measures or to gain access to a system or environment. Shimming is often used to bypass locks, access control systems, and other security mechanisms. It can also be used to hide exploits and gain access to sensitive data or resources. As the security landscape continues to evolve, shimming will likely continue to be an important tool for those looking to gain access to restricted areas or information.
