Scammers are finding new ways to exploit unsuspecting individuals through scam websites, fraudulent calls, and mobile trojan campaigns. In Hong Kong, scam websites disguised as WhatsApp login pages continue to top Google search results, despite efforts to remove them [2345603b].

To combat this, experts are calling for enhanced security measures, including stricter verification processes and stronger encryption protocols [2345603b]. Similarly, in Palghar, a man fell victim to a power bill fraud scam after receiving a deceptive phone call [8b35ef59]. The scammer sent a malicious file via WhatsApp and coerced the victim into making a transaction and sharing personal details, resulting in the loss of ā‚¹3.50 lakh from the victim's bank account [8b35ef59]. These incidents highlight the need for individuals to be cautious and vigilant when interacting with unfamiliar websites and phone calls. It is important to verify the authenticity of websites and refrain from sharing personal information or making transactions without proper verification [2345603b] [8b35ef59].

Meanwhile, in Hong Kong, authorities have deactivated over 1 million SIM cards in the past year due to owners failing to complete real-name registration [8aed8768].

The regulation, which took effect in September 2021, requires all SIM card users in Hong Kong to register their personal information before February 2023. The measure has been effective in reducing the number of scams in Hong Kong, with a 38.1% decrease in telephone fraud cases in the fourth quarter of 2023 compared to the same period in 2022.

Banking Trojan Medusa is back and more dangerous than ever. It is tough to detect and is wreaking havoc on phones across the US and Europe. The Trojan, which first affected Turkish business establishments in 2020, has now expanded to other countries in Europe as well as the US. Since July 2023, Medusa attacks have resurfaced with a new version.
