![]() However, there was a difference between the two hijacks of Twitter’s 104.244.42.0/24 by Myanmar in 2021 and then again by Russia in 2022. Unfortunately, their hijack route was inadvertently leaked out of Myanmar, causing disruptions to Twitter around South Asia.Īnd finally, last year, during Russia’s crackdown on social media and independent journalism following their invasion of Ukraine, a Russian ISP elected to use BGP to blackhole traffic to Twitter by hijacking the exact same prefix (104.244.42.0/24) that was hijacked a year earlier in Myanmar. To comply with the order, one Myanma ISP elected to use BGP in order to hijack local Twitter traffic and drop it. More recently, during the initial weeks of the Myanmar military coup in 2021, the military junta in charge ordered social media to be blocked. Over the years, there have been many such leaks of BGP hijacks meant to censor content, such as those in Ukraine and Iran. However, the hijacks leaked out of Pakistan, leading to a global disruption of Youtube. The Pakistani state telecom, PTCL created BGP routes to hijack traffic destined for Youtube and blackhole it. In that case, the Pakistani government ordered a block of Youtube in the country. Perhaps the most famous BGP hijack ever was Pakistan’s hijack of YouTube in 2008 (also see The Internet’s Biggest BGP Incidents). A ROA is a record in RPKI that specifies the AS origin that is authorized to originate the IP address range. However, despite this technical error, no Telegram disruption was reported outside of Iraq, in part, due to the fact that Telegram had created Route Origin Authorizations (ROAs) for its routes allowing ASes outside of Iraq to automatically reject the hijacks. And, as has happened before on numerous occasions, these hijack BGP routes leaked out of the country. According to data from our friends over at Tor’s Open Observatory for Network Interference (OONI), the block was implemented by blocking Telegram’s IP addresses.Įvidently, when the Iraqi government began blocking Telegram, it started by using BGP to hijack traffic destined for IP addresses associated with the messaging service, redirecting them to the proverbial bitbucket. This past weekend, the government of Iraq took the step to block the popular messaging app Telegram, citing the need to protect the personal data of Iraqi users following a leak of confidential information.
