MalwareBazaar only tracks malware samples. No adware (PUA/PUP). No benign files. Samples older than 10 days, PUAs/PUPs and benign files should not be uploaded to the repository.
There are some mechanisms in place to flag PUA/PUP files, where files are reviewed and removed manually by the admin. However, it is important to note that there is no automatic enforcement of the PUA/PUP policy.
Submission vetting is manual and relies on researchers and users reporting such submissions. Where unacceptable files are reported by the community, files are removed promptly, and the responsible user banned.
A file can only be present once on MalwareBazaar, therefore it is not technically possible to upload two copies of the same sample.
No, tags are not included in the MalwareBazaar historical malware sample data (full.csv).
Accelerate investigations and resilience against malware and botnets with robust, reliable, community-driven threat intelligence. These real time feeds will be available soon.
In this report, we highlight malware trends utilizing data from abuse.ch’s open platforms. These collect, track and share resources relating to malware campaigns, including the URLs of malware distribution sites, malware samples, and indicators of compromise.
On Monday, August 1st, 2022, Spamhaus Technology became the primary licensee of data produced by abuse.ch. Here's an outline of why this partnership was conceived and what it hopes to achieve in the future.
