The 'Resize ShadowStorage Volume' detection rule is designed to identify the resizing of shadow storage volumes, which is a technique often employed by ransomware groups such as CLOP. When ransomware attempts to manipulate shadow copies, it hinders recovery efforts and increases the risk of data loss. This particular rule utilizes data obtained from Endpoint Detection and Response (EDR) tools, focusing specifically on command-line interactions involving 'vssadmin.exe'. By analyzing events where this tool is executed with parameters indicating resizing actions ('*resize*' and '*shadowstorage*'), the rule can flag potentially malicious activities. Detection occurrences are assessed based on the process context and historical data, making it a critical measure for mitigating ransomware threats and ensuring endpoint security.
