Implementation Proofpoint for Science mail   news

Unfortunately, we have recently seen a strong increase in successful phishing attempts in the Science domain, a mailing about this issue was already sent last week. At the same time, we worked hard in collaboration with ILS to also deploy the centrally used anti-phishing tooling from Proofpoint for FNWI. The central RU mail environment has been supplemented with this highly effective anti-phishing measure for some time now. As soon as the Science mail domains are also placed ‘behind’ this anti-phishing tool, things will change for users who have not yet had to deal with this....

The phishing email often contains something about salary or a payment, which means that it is clicked a lot. C&CZ is doing everything it can to limit the nuisance as much as possible by blocking these phishing emails as much as possible....
