Where are good places to submit samples of potential malware for analysis?
WordFence does this, which I assume is mutually beneficial because it helps them keep ahead. Are there any others doing code analysis?
According to this WordFence doc:
I have a file that looks suspicious, but I’m not sure if it is. How can I tell?
Email it to us at samples@wordfence.com and we’ll let you know. If you don’t receive a reply, either your mail system or ours may have discarded the message thinking it was malicious because of your attachment. So please email us a message without the attachment letting us now that you’re trying to send us something and we’ll try to help get it through.
