Top Scams Reported in the Last 24 Hours

Fake Wi-Fi spots
Seven in ten British users have been found using free public Wi-Fi, with 25% of them failing to check the legitimacy of the public hotspot. This can allow cybercriminals to eavesdrop on users and steal usernames, passwords, and bank details. The Wi-Fi connections are created to have innocuous-sounding names such as ‘airport WiFi’ or ‘hotel Wifi’ and can also redirect victims to malicious sites and phishing sites.   

1000GB of free data scam
A new WhatsApp scam that claims to offer 1000GB of free internet data to users has been doing rounds on the internet lately. The offer claims to be a part of the 10th anniversary for WhatsApp and is provided as a gift to users who have been loyal to the service. It includes a link which a user needs to click on to avail the offer.
