Researchers have discovered two vulnerabilities that could allow threat actors to abuse hosted email services in order to spoof the sender's identity and evade protections. The identified vulnerabilities impact millions of domains. The CERT Coordination Center (CERT/CC) at Carnegie Mellon University warns that authenticated attackers can spoof the identity of a shared, hosted domain and use network authorization to spoof the email sender. The flaws stem from the failure of many hosted email services in properly verifying trust between the authenticated sender and their allowed domains.

According to researchers at the University of the Republic of Uruguay, hackers can apply Artificial Intelligence (AI) to spy on a user's display by capturing leaked electromagnetic radiation from a PC's HDMI cable. Hackers can carry out the attacks using various methods, such as placing an antenna outside a building to intercept signals from the HDMI cable. Once they have successfully intercepted the data, hackers can take additional steps to gain access to users' sensitive data.
