OpenDNS 停止在法國的 DNS Resolver 服務

前陣子法國法院要求在 DNS 層阻擋的事情 (參考「Google Public DNS 接受法國法院的阻擋要求」) 有新的進度了，OpenDNS 直接停止在法國的 DNS Resolver 服務：「OpenDNS Suspends Service in France Due to Canal+ Piracy Blocking Order」。

不是把法國當地的服務停掉改由其他地區的 anycast 提供服務，而是在服務本身上面直接阻擋法國的使用者：

Reports of problems with the OpenDNS service seemed to begin on Friday, and it didn’t take long to discover the cause. The technical issues were isolated to France and apparently parts of Portugal too, with an explanation having appeared on the OpenDNS website, perhaps as early as Thursday evening.

網站上的公告則是：

Effective June 28, 2024: Due to a court order in France issued under Article L.333-10 of the French Sport code and a court order in Portugal issued under Article 210-G(3) of the Portuguese Copyright Code, the OpenDNS service is not currently available to users in France and certain French territories and in Portugal. We apologize for the inconvenience.

這下衝突升級了...

BGPmon 推出 BGP Stream 警告異常的 BGP 流量劫持

也是兩個禮拜前的新聞，在「OpenDNS BGP Stream Twitter Feed」這邊提到了 BGPmon 將會推出 BGP Stream 服務，將偵測到的 BGP 異常變化發到 Twitter 上。

其中 BGPmon 在幾個月前被 OpenDNS 併購 (2015 年 3 月)，而 Cisco 則在上上個月底併購了 OpenDNS (2015 年 6 月)。而在過幾天的 DefCon 23 上將會透露更多細節。

前陣子 Hacking Team 洩漏的資料中就用到了 BGP hijack 來取回控制權：

That nugget that emerged from the 400 Gb of stolen Hacking Team data posted online where Italian law enforcement used Hacking Team’s Remote Control System monitoring software to regain control over a number IP addresses it was watching that were already infected with Hacking Team software by hijacking BGP routes in order to redirect traffic and regain control over a target’s machines.

除了示警外，另外一方面 BGP 上的簽名技術也愈來愈重要了，只是不知道最終會怎麼做...
