I have asked Cloudflare about this traffic, but support says "Cloudflare helps protect sites, and accelerate them. We do not attack sites, and our network can't be used to generate attack traffic." They deny any malicious outgoing traffic, but after I have provided pcap dump they just ignoring me and do not reply anything. Very odd behaviour for researchers.

Cloudflare likes to use the "We're just a proxy" defense when it suits them, but with the rapid release of other products they are very capable of generating arbitrary traffic and hosting content without an origin.
