Hong Kong police launched an anti-money laundering operation involving HK$470 million, and the money laundering methods included buying and selling cryptocurrencies

According to Sing Tao Daily, the Hong Kong police launched an anti-money laundering operation this month, arresting 458 people suspected of money laundering and related crimes from 314 cases involving a total amount of HK$470 million. During the operation, the police successfully intercepted more than HK$16 million in criminal proceeds. The police said that a money laundering group induced locals and foreigners to sell their bank accounts for HK$300 to HK$1,500 to launder the criminal proceeds of various frauds. From October last year to June this year, the group was suspected of laundering up to HK$110 million in criminal proceeds by withdrawing cash and buying and selling cryptocurrencies. In addition, members of the money laundering group invited some of the arrested persons, induced them to hand over their ID cards and take selfies on their mobile phones, and then helped them open virtual bank accounts privately.

CZ: Due to Kroll data leak, a new round of phishing attacks against FTX, BlockFi, and Genesis users has begun

Binance founder Changpeng Zhao (CZ) said on the X (formerly Twitter) platform that a new round of phishing attacks against FTX, BlockFi, and Genesis users has begun due to the Kroll data leak (which seems to be the result of an employee changing SIM cards). CZ reminded users to learn to protect themselves and be aware of phishing attacks.

Earlier news, FTX's bankruptcy claims agent Kroll was attacked, and some claimants' non-sensitive customer data was leaked. FTX has taken preventive measures against the Kroll cybersecurity incident and temporarily frozen the affected user accounts. In addition, BlockFi claimants' data was also leaked in the Kroll attack.
