Yesterday Google’s Bangladeshi website google.com.bd was hacked and this happened via DNS. It was reported on the bdNOG mailing list at morning in a thread started by Mr Omar Ali.
This clearly shows how authoritative DNS for “com.bd.” (which is same as bd. btw) was poisoned and was reflecting attackers authoritative DNS. Later Mr Farhad Ahmed posted a screenshot of google.com.bd showing hackers page:
Later Mr Sumon Ahmed mentioned that it happened because web frontend of .

So last month I had a wonderful trip to Bangladesh for bdNOG. This is bit delayed. Some thoughts on infrastructure
In terms of infrastructure - roads & traffic, power, quality of builds - it seemed like India in 2000’s. Specifically roads and traffic was bit terrible and even as an Indian (who manages to drive in Indian traffic!) I still got scared out of traffic in Dhaka. Speeds, roughness and overtaking is pretty high.
This week I presented in bdNOG 4 on “Misused top ASNs”. It was a study we at Hurricane Electric did to see how many times AS1, AS2 and AS3 appeared in global routing table between 2010 and 2015. This highlights cases where AS1, AS2 or AS3 appeared as a result of wrong prepend. My presentation is embedded below:
Overall bdNOG 4 had been a great experience. It’s good to see a nice NOG community actively sharing technical know-how, sharing experiences, and much more.
