Bitcoin.org was reported to be a distributed denial-of-service (DDoS) attack at midnight last night.
Bitcoin.org is a website dedicated to those who want to learn about bitcoin (BTC) and at the same time it supports the development of the king of cryptocurrencies.
The incident was reported on Twitter by its owner known as Cøbra: "Bitcoin.org was attacked by DDoS and they need a ransom or the attack will continue."
It is said that 0.5 BTC (around RM 70,517) was claimed by the hackers.
This is not the first time the website has been attacked by DDoS. In December a similar incident occurred causing users to fail to access the Bitcoin Core software for several hours.
DDoS attacks are also synonymous with targeting crypto exchange platforms such as Binance, OKEx and Bitfinex.
Bitcoin.org has been in the spotlight lately starting with legal threats from an individual claiming to be Satoshi Nakamoto, Craig Wright.
Then last week, a United Kingdom (UK) court ruled in a victory over Wright who claimed Bitcoin.org had infringed copyright by uploading a Bitcoin white paper.
However Cøbra did not retaliate.
As a result, Bitcoing.org has blocked access for Bitcoin Core software downloads for any user accessing using a UK IP address and any links associated with the Bitcoin white paper have also been deleted immediately.
At the time of writing, Bitcoin (BTC) is trading at $ 33,903 with a decline of almost 2% in 24 hours.
