In reply to Cristi.

Thank you for writing. I have updated the blog post to add a link to the RIPE transfer page, and noted that VisNetwork Media SRL was the previous owner of the IP space in question.

I too find it quite disconcerting that so many of yours and others' IP allocations have been hijacked by this Bulgarian AS. Cisco Talos is continuing to examine these and other malicious BGP prefix announcements with great interest. If you have any additional specific details you can share, please contact me via email at jaeson[at]cisco.com.
