A new service has been launched that allows you to check if an email domain or address was used as a sender or recipient in Emotet spam campaigns. TG Soft has collected over 2.1 million email addresses from around 700,000 outgoing emails between August and September 23rd, 2020. The company has collected more than 2 million emails since then. If you find your email address or domain has been used as the sender of an email or recipient, it does not necessarily mean that you have been infected.
