Norton just blocked malicious attack from Yahoo mail page (the page itself, not opened emails)
A few seconds after I loaded the Yahoo mail page, my Norton anti-virus alerted me with 2 alerts:
Medium severity: An intrusion attempt by rdtk.io was blocked.
Attacking Computer rdtk.io(188.8.131.52, 443)
Attacker URL https://mf70e.rdtk.io
High severity: An intrusion attempt was blocked.
This one has a very long Attacker url with "mail.yahoo.com" as part of it.
