According to CoinDesk, on June 19th, information security company LAC drafted a new hacker group report on attempts to steal cryptocurrencies. According to the report, the hacker group known as "HYDSEVEN" has been conducting cyber attacks in countries including Japan and Poland since 2016. According to the report, it is speculated that the group uses Russian language to conduct activities. “HYDSEVEN” was named by the LAC because the words “HYD” and “SEVEN” were used many times during the attack. Most of HYDSEVEN's attacks are to send e-mails and steal personal information to specific organizations and individuals. They also pretend that researchers at university research institutes have launched attacks.
