The detection of phishing Portable Document Format (PDF) files using an image-based deep learning approach is disclosed. A PDF document that includes a Universal Resource Locator is received. A likelihood that the received PDF document represents a phishing threat is determined, at least in part, by using an image based model. A verdict for the PDF document is provided as output based at least in part on the determined likelihood.

Techniques for identifying malware based on system API function pointers are disclosed. In some embodiments, a system/process/computer program product for identifying malware based on system API function pointers includes monitoring changes in memory during execution of a malware sample in a computing environment; detecting a dynamic evasion behavior using an Application Programming Interface (API) vector comprising a plurality of system API function pointers identified in the memory during execution of the malware sample in the computing environment; and generating a signature based on the API vector for automatically detecting the malware during execution in the memory, wherein the malware sample was determined to be malicious.

Techniques for early exit dynamic analysis of a virtual machine are disclosed. In some embodiments, a system/process/computer program product for early exit dynamic analysis of a virtual machine includes initiating a dynamic analysis of a malware sample by executing the malware sample in a virtual computing environment; monitoring activities of the malware sample during execution of the malware sample in the virtual computing environment; and determining when to exit the dynamic analysis before a predetermined period of time.
