Malware Samples

I’m always on the lookout for good malware datasets so decided to keep this log of online repositories.

VirusTotal have an API and allow yout to refine your search based on a number of factors such as: number of AV scanners that have marked the sample as malicious or trusted; protocols (e.g. http); network activity etc

VirusShare have a bucketload of samples and have very kindly curated some useful sample sets (scroll to bottom of the Torrent page) for Android, Linux, 64-bit Win and Ransomware

Maltrieve is not something I have used but looks like an interesting crawler for Malware across a number of sites
