in the AppData folder, which malware targets in ransomware attacks. Best practice: During an outbreak, set this rule to block and report to help stop or slow the infection. This rule can result in false positives depending on whether the contained program is truly malicious or not. Reading files Prevents contained processes from commonly reading files that ransomware-class targeted by malware commonly targets. Ransomware ransomware-class sometimes tries to read the files into malware memory, write the file contents to a new file, encrypting it, and then deleting the original. Ransomware-class malware does not typically try to directly change the files it is targeting for encryption. Instead, it uses a process already on the system, such as explorer.exe or powershell.exe, to proxy the attack. If enough attempts are blocked, the malware might fall back to trying to encrypt the file directly. Reading from Prevents contained processes from another process’ reading the memory from another process memory on the system. This rule can help thwart attempts to steal information contained in targeted processes. Reading or Prevents contained processes from modifying files on reading or changing files on network any network locations. Malware can use these locations location to spread infected files. Best practice: During an outbreak, set this rule to block and report to help stop or slow the infection. Reading or Prevents contained processes from modifying files on reading or changing the contents of CD, floppy, and removable devices. Malware can use these removable drives devices to propagate. Best practice: During an outbreak, set this rule to block and report to help stop or slow the infection.
