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. More information can be found on https://www.ru.nl/ict/algemeen/proofpoint/. ...

Last week we have seen a strong increase in phishing attempts targeting the Science domain. It is notable that these attempts use well-constructed Science environments such as Roundcube that are difficult to distinguish from the real environment. 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. ...

From now on it is possible to manage Science accounts under your control in DIY. The overview of Science accounts for which you are the contact can be found in the menu “My accounts”. Each of these accounts has a link to a form where you can perform one of the following actions: Postpone the check date. This date is used to send reminder emails. Block the account. Blocked accounts cannot be used to login into systems (like mail, login server, gitlab). Delete the account. If you delete an account, the account will be blocked immediately and will be deleted a month later. If the check date of a Science account has passed, a reminder email will be sent inviting you to indicate in DIY what to do with the account. In most cases it is therefore no longer necessary to send a reply to this e-mail. ...
