Edwin Engels has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • 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.

  • Mitigation of return-oriented programming attacks
    Patent number: 11853414
    Abstract: Trampoline and return-oriented programming attacks employ a variety of techniques to maliciously execute instructions on a device in a manner different from a legitimate programmer's original intent. By instrumenting a device to detect deviations from predicted behavior, these exploits can be identified and mitigated.
