![]() ![]() It is hard to discover all threats that may be present within files by using static analysis, since the content of the file itself usually is not malicious, but an embedded object will perform the malicious behavior (by downloading a malicious payload, getting access to PowerShell, etc.). Macros were always a pain point in fighting against malware, but nowadays there are a lot more advanced threats. Malware, especially ransomware, can infect devices by using embedded objects such as scripts and macros in common file types used for productivity. More and more attackers are using common file types to deliver targeted malware attacks. OPSWAT offers REST APIs in order to make multi-scanning technology available for this kind of use case. There are a few solutions out there that expose one or multiple antivirus APIs, but the best tactic is to analyze uploaded files using multiple anti-malware engines.įor better detection rates, use a multi-scanning solution, instead of a single antivirus API. This might be a drawback for some businesses, so align your business needs to your implementation - if you need the files analyzed in a fraction of a second, you need to rely on an antivirus API integrated directly in your infrastructure.įor such an integration, you can either integrate directly with an antivirus API or use third-party solutions that expose an API on top of the antivirus API. The workflow should be clear and simple: Any uploaded file should be analyzed for known malware, and the file shouldn't be made available to end users until the analysis is complete.ĭepending on the API integration and the volume of files being uploaded, this can cause a delay that varies from a few hundred milliseconds to actual minutes. The first and most important step to take is to scan all file uploads for known malware. If file uploads are essential for your business to run, there are several steps you need to take in order to ensure that no infected, malicious, or otherwise compromised files are uploaded into your system. ![]()
