Please be aware and vigilant of phishing attempts. Phishing is a method of luring individuals, often via email, into providing sensitive data such as personally identifiable information, banking and credit card details, and passwords.

Phishing emails may ask a user to click on a link to verify their account information, open an attachment to view a document, message, or verify their username and password by replying to the email or filling a webform. One common phishing scam is to warn you that your email is "over quota" and you must click the link to verify your account. CSAIL does not and will never have an email quota.

Note, that neither CSAIL or MIT will ever ask for your password.

If you have the slightest doubt or suspicion of an email, aways veer on the side of caution and please reach out to us before proceeding.
