Due to email forwarding vulnerabilities, attackers might pretend to be well-known sites. According to a research team lead by computer experts at the University of California San Diego, sending an email with a falsified address is simpler than previously believed because of bugs in the system that permits email forwarding.
The problems discovered by researchers have a significant impact, compromising the integrity of emails sent from tens of thousands of domains, including those that are associated with the United States government, including the majority of cabinet email domains, such as state.gov, and security agencies.
