Abstract: Systems and methods are presented for performing sandboxing to detect malware. Sample files are received and activated individually in separate sandboxes in one mode of operation. In another mode of operation, sample files are assigned to pools. Sample files of a pool are activated together in the same sandbox. The sample files of the pool are deemed to be normal when no anomalous event is detected in the sandbox. Otherwise, when an anomalous event is detected in the sandbox, the sample files of the pool are activated separately in separate sandboxes to isolate and identify malware among the sample files.

Abstract: An email inspection system receives emails that are addressed to recipients of a private computer network. The emails are inspected for malicious content, and security information of emails that pass inspection is recorded. When an email is detected to have malicious content, the recorded security information of emails is checked to identify compromised emails, which are emails that previously passed inspection but include the same malicious content. A notification email is sent to recipients of compromised emails. The notification email includes Simple Mail Transfer Protocol headers that facilitate identification of the recipients, blocking of incoming emails with the same malicious content, and identification of public Mail Transfer Agents that send malicious emails, i.e., emails with malicious content.
