Hey, don't route the messenger! Telegram redirected through Iran by baffling BGP leak

Updated A bunch of Telegram messages went the long way round on Monday: a BGP leak sent people's Telegram chat communications via systems in Iran. Flagged by OpenDNS's BGPMon as a possible BGP hijack, the cockup could also have been a simple case of a sysadmin typo, since the redirection of packets only lasted two hours and fifteen …

BGP borked? Blame the net's big boppers

The Internet's fundamental routing infrastructure, the Border Gateway Protocol (BGP), is so fragile that errors in one to four per cent of ISP route filters can propagate bad routes. So says Czech DDOS-defender Qrator Labs, which carried out a project to try and help the Internet community quantify how much of the threat to …

Router admin? Bored? Let's play Battleships using BGP!

Playing Battleships over the Border Gateway Protocol probably wasn't a scenario considered by the standard's authors, but UK blogger Ben "Jojo" Cox has explained how to do it. Cox's tutorial is part amusement, part warning, because while explaining the protocol (and why it's hard to fix), he pointed out that in the 32 bits …

Net boffins brew poison for BGP hijacks

The Border Gateway Protocol (BGP) is one of the Internet's basic pieces of plumbing technologies, but it's also so old it was designed before the security needs of a multi-billion-user network were understood. In particular, BGP is notorious for allowing sysadmins to “black-hole” huge swathes of traffic either by fat-fingering …

Cisco borked its own BGP code in IOS XE, has since patched

Cisco's pushed a fix for a border gateway protocol (BGP) denial-of-service bug in its IOS XE operating system.

Internet boffins take aim at BGP route leaks

One of the most persistent bugs in internet infrastructure, route leaks in the border gateway protocol (BGP), is in the sights of a group of 'net boffins with their new Internet-Draft. BGP's one of the internet's persistent trouble-spots: ineradicable because it's ubiquitous, it's vulnerable because it's ancient, a relic of a …

Evil ISPs could disrupt Bitcoin's blockchain

Attacks on Bitcoin just keep coming: ETH Zurich boffins have worked with Aviv Zohar of The Hebrew University in Israel to show off how to attack the crypto-currency via the Internet's routing infrastructure.

Fat-thumbed a BGP entry? Relax, now your pain has a name

Users are familiar with those occasional events in which a sysadmin fat-thumb results in traffic getting deep-sixed – like, for example, this week's huge Telia outage. It's a problem that plagues the Internet and has done for years: the foundational Border Gateway Protocol (BGP) was designed in an era long-gone where sysadmins …

Google cloud outage caused by failure that saw admins run it manually ... and fail

A mistaken peering advertisement from a European network took Google Cloud's europe-west1 region offline last week for around 70 minutes. The slip-up happened when an unnamed network owner connected a new peering link to Google, and in the process, it advertised reachability for far more traffic than it could handle. As a …

OK, who unplugged the modem? North Korea's internet disappeared for four hours today

North Korea disappeared from the internet on Monday for roughly four-and-a-half hours. At around 6.30pm local time (or 6pm if you take the starving nation's recent decision to create its own time zone seriously) through to 11pm, the routes for the country vanished from the internet's routing tables, meaning nothing was coming …

Russian internet traffic detours through China's Frankfurt outpost

Russian domestic internet traffic has in the past year sailed through Shanghai due to routing errors by China Telecom, network boffin Doug Madory says.
