Threat actors have taken phishing attacks to a whole new level. A recent phishing campaign saw attackers targeting Gmail users through fake and unsolicited Google Calendar notifications. In the scam, they exploited a default feature in Google Calendar to add fake invitations and events to the users’ calendars automatically.

In another phishing incident, malicious actors have been found using TLS-secured landing pages to trick users. They are incorporating a third-party verified certificate into the website before sending it to users’ emails. This way, users are tricked into believing that they are opening a secured website and end up sharing their personal details with the cybercrooks.

Three Russian banks - OTP Bank, Alfa Bank, and HCF Bank - have exposed sensitive details of 900,000 customers due to leaky databases. The compromised information includes names, phone numbers, passports, residential addresses and place of work of individuals.
