According to news on November 29, the Singapore Police Force and the Cyber ​​Security Agency issued a joint statement stating that criminals have recently been observed to use a variety of methods to steal cryptocurrency from victims’ cryptocurrency wallets. Their common tactics include impersonating legitimate entities on social media, offering giveaways or promotions as bait, and asking victims to "verify" their wallets by sharing personal information such as login credentials. In addition, criminals may also use phishing websites, software vulnerabilities, smart contracts, etc. to invade the victim's wallet and transfer cryptocurrency. Singaporean government departments call on the public to take preventive measures to protect wallets, such as: using higher-security offline storage devices such as hardware wallets; using strong passwords and two-factor authentication; checking accounts frequently, etc.
