MDATP File Hash Indicators

Iron Contributor


I am not allowed to upload MD5 file hashes into the Indicators Tab for Microsoft Defender Security Center. It also shows a message that MD5 file hash method is not recommended.


I have around 500 MD5 hashes for IOCs which I need to upload. Is there a way around through which I can cover these MD5 file hashes to SHA-1 or SHA-256 and then upload in Defender Security Center.

This is now resolved. Used the Virustotal api to get the corresponding SHA-256 hash for MD5Hash.


For the MD5 hashes where there were no results on Virus Total, raised the case with Microsoft. I believe some changes were done from MS end after which I got MD5 file hashes uploaded.
