Companies like this launch ICO to let them raise funding from multiple sources.Etherparty said the company launched its Fuel token sale on Sunday, October 1 at 9 A.M. PDT, but just 45 minutes, some unknown attackers hacked into its ICO website and replaced the legitimate address by their own, redirecting cryptocurrencies sent by investors into their digital wallet.According to the details released by the Etherparty team, the company detected the hack after just 15 minutes and immediately took its website down for nearly one and half hour to fix the issue, preventing more people from sending funds to the hacker's address.By 11:35 A.M. PDT, the website was rebuilt and switched to a new web server , which also includes a pro tip on the top of it that reads: "."Although Etherparty did not reveal details on how many funds were stolen, the company was really quick in figuring out the whole incident, taking appropriate steps, and alerting people of the hacking incident by distributing a press release The blockchain company has also "." The Etherparty's ICO is still ongoing and open until October 29, 2017.Etherparty also said despite the hacking incident, its ICO got off to a positive start, "selling over 10,000,000 FUEL tokens in the first hour," and sold more than 400,000,000 FUEL tokens before the official launch in the pre-sale.This incident marks the latest cyber attack on an ICO, following a theft of nearly $471,000 worth of Ethereum in cyber attack that hit Enigma Project in August, around $8.4 Million worth of Ethereum in hack that hit Veritaseum's ICO in July, and $7 Million worth of Ether tokens during the hack of Israeli startup CoinDash's ICO a week prior to Veritaseum's ICO hack.Due to rising concerns surrounding ICOs over such hacks and scams, regulators globally are taking action against ICO fundraising. China has already announced an immediate ban on all ICO across the country.In the United States, the Securities and Exchange Commission (SEC) has also issued an official warning about the risks of ICOs but has not made a firm move yet.
