Largest South Korean cryptocurrency exchange Bithumb reported about "billions of wons" stolen by the hijackers. BraveNewCoin reports about it.

Due to last week cyberattack, hackers was able to stole personal data of 31 800 Bithumb users. That's 3% of all exchange's clients base. 

Stolen data consists of names, cellphones and email addresses of users. Local newspaper Kyunghyang Shinmun reported that one user lost around 8700$ due to hacker attack.

Bithump located the hijack on 29th of June and called the police on the next day. Also, more than 100 users contacted More than 100 users contacted the National Police Agency's cybercrime report center.

Representatives of Bithumb argue that there was no direct access to the users' accounts and that the attack was not directed to the internal network of the exchange servers or wallets, but to the computer of one of the Exchange's employees.

After the theft of user data from the computer employee Bithumb fraudsters engaged in "voice phishing". So, one of the users said that they called him, introduced themselves as a Bithumb employee and asked to dictate a one-time password sent by email. After the client of the Korean stock exchange complied the request of the "employee", from his account were stolen bitcoins in an amount equivalent to $ 8,700.

The newspaper also says that despite the fact that the exchange appealed to the law enforcement agencies of the country, about 100 injured clients plan to file a lawsuit against Bithumb.

While it remains unclear what kind of legal responsibility the trading platform will bear for lost user funds. The situation is significantly complicated by the absence in the country of regulatory and legal regulation of the regulation of the crypto-currency sphere.

The 22-year-old cryptocurrency millionaire lost more than 5,500 bitcoins after taking part in the investment scheme in Thailand. The case attracted public attention because of the possible participation of a Thai actor. This is reported by Bangkok Post.

A group of scammers in June 2017 persuaded Finnish businessman Aarni Otawa Saarimaa to invest in several Thai securities, a casino in Macau and a crypto currency called Dragon Coin.

Scammers claimed that Dragon Coin could be used in Macau casinos. In addition, they brought Saarimaa to this casino to demonstrate the legitimacy of their project. Saarimaa transferred 5 564 BTC to fraudsters.

In January, without receiving any income for his investments, Saarimaa filed a complaint with the Crime Suppression Division's (CSD), along with his local business partner, who believed that this investment scheme was fraudulent.

CSD began to investigate the case and stated that the group made no investment for Saarimaa, instead transferring all the bitcoins to Thai baht and placing these funds on seven bank accounts.

Although it is not clear when exactly the scammers sold the bitcoins, CSD announced that they raised about 800 million baht or about 24 million dollars.

Then followed a months-long investigation, according to which CSD began to suspect that the Thai film actor Jiratkisit "Boom" Jaravijit also took part in the fraudulent scheme - he was arrested last Wednesday.

In addition, the CSD stated that it suspects the actor's brother, Princess Jaravijit, as the "instigator" of this entire scheme. He left Thailand, traveling to South Korea, and then to the United States. According to the Bangkok Post, CSD is currently working with the US to track him down.
