Malicious code scanning of remotely-located files
11574058 · 2023-02-07 · ·

A file is stored in a public cloud storage. A serverless computing platform receives an event notification that the file has been stored and, in response, creates an instance of an ephemeral environment wherein a security module is executed. The security module creates a memory-mapped space with memory locations that are mapped to the entire content of the file but does not allocate memory for all of the memory locations. Instead, the security module retrieves sections of the file from the public cloud storage as these sections are accessed in their designated memory locations in accordance with the memory mapping, allocates memory for the retrieved sections, stores the retrieved sections in their designated memory locations, and scans the retrieved sections in their designated memory locations for malicious code. The security module continues scanning the file in sections until relevant sections of the file have been scanned.

SYSTEM AND METHOD FOR DETECTING INSIDER THREATS IN SOURCE CODE
20230041068 · 2023-02-09 ·

A code repository stores source code. An insider threat detection system stores instructions for detecting code defects and criteria indicating predetermined types of code defects that, when present, are associated with intentional obfuscation of one or more functions of the source code. The insider threat detection system receives an entry of source code and detects, using the model, a set of code defects in the entry of source code. A defect type is determined for each code defect, thereby determining a set of defect types included in the entry of source code. If it is determined that each of the predetermined types of code defects indicated by the criteria is included in the determined set of defect types, the entry of source code is determined to include an insider threat.

Guided Micro-Fuzzing through Hybrid Program Analysis
20230044951 · 2023-02-09 ·

Program analysis is provided. An intermediate representation of a program is generated. A set of structured inputs is provided to the program. The set of structured inputs are derived from the intermediate representation. The program is executed using the set of structured inputs. A set of action steps is performed in response to observing a violation of a policy during execution of the program using the structured inputs.

Expediting processing of selected events on a time-limited basis

Techniques are described that enable an IT and security operations application to prioritize the processing of selected events for a defined period of time. Data is obtained reflecting activity within an IT environment, wherein the data includes a plurality of events each representing an occurrence of activity within the IT environment. A severity level is assigned to each event of the plurality of events, where the events are processed by the IT and security operations application in an order that is based at least in part on the severity level assigned to each event. Input is received identifying at least one event of the plurality of events for expedited processing to obtain a set of expedited events, and the identified events are processed by the IT and security operations application before processing events that are not in the set of expedited events.

Portable policy execution using embedded machines

Some embodiments provide a method for evaluating authorization policies that restrict access to API (Application Programming Interfaces) calls to an application executing on a host system. At the application, the method receives an API call to execute. The method directs a process virtual machine (VM) executing inside the application to make an authorization decision for the API call. The method executes the API call after receiving an authorization decision to allow the API call from the process VM executing inside the application.

Identifying a software vulnerability
11593491 · 2023-02-28 · ·

Systems and methods to identify a software vulnerability are described. The system receives a message identifying a software vulnerability. The system identifies snapshot images taken of a production machine and stored in a database. The snapshot images include a snapshot image including a virtual machine. The snapshot images are identified being based on the message. The system identifies whether the snapshot images include the software vulnerability. The system registers the software vulnerability in association with a snapshot image in the database responsive to the identification of the snapshot image of the virtual machine including the software vulnerability.
