  • Encrypted cache protection
    Patent number: 11929992
    Abstract: Secrets such as secure session cookies for a web browser can be protected on a compute instance with multiple layers of encryption, such as by encrypting key material that in turn controls cryptographic access to the secret. A compute instance can be instrumented to detect when a process attempts to decrypt this key material so that the process requesting decryption can be compared to authorized or legitimate users of the secret.
    Type: Grant
    Filed: September 7, 2021
    Date of Patent: March 12, 2024
    Assignee: Sophos Limited
    Inventors: Mark Willem Loman, Lute Edwin Engels, Ronny Henk Gert Tijink, Victor Marinus Johann Simon van Hillo, Alexander Vermaning, Jeroen Harmsen
  • Malware mitigation based on runtime memory allocation
    Patent number: 11880453
    Abstract: A compute instance is instrumented to detect certain kernel memory allocation functions, in particular functions that allocate heap memory and/or make allocated memory executable. Dynamic shell code exploits can then be detected when code executing from heap memory allocates additional heap memory and makes that additional heap memory executable.
