In April 2017, Rostelecom (AS12389) originated 50 prefixes for numerous other [[autonomous system (Internet)|autonomous systems]] (AS). The [[BGP hijacking|hijacked]] prefixes belonged to financial institutions (most notably MasterCard and Visa), other telecom companies, and a variety of other organizations.<ref>{{Cite web|url=https://bgpmon.net/bgpstream-and-the-curious-case-of-as12389/|title=BGPstream and The Curious Case of AS12389 {{!}} BGPmon|website=bgpmon.net|language=en|access-date=2017-10-17}}</ref> What makes the list of affected networks 'curious' is the high number of financial institutions such as: MasterCard, Visa, Fortis, Alfa-Bank, and more. The other notable characteristic of this event is that the advertisement included several more prefixes that were more specifically defined thatthan the prefixes normally announced, which makes it less likely that these were unintentionally leaked prefixes.
