The term, "Phishing", is used to describe a style of scam conducted over email, where someone poses as a trusted official, administrator, or business, and attempts to gather sensitive information. The concept of phishing has existed for a long time, though the styles of phishing attempts continue to evolve.
The most common result of a successful phishing attempt is identity theft. The victim is no longer in control of their email account, and the phisher is able to access the content of the victims' email account and contact list, and possibly other connected applications like the victims' calendar or cloud drive. In addition, if the victim used the same password with other applications and services, the phisher has potentially gained access to those as well.
If you accidently send your account credentials via email, immediately change your password by following the steps listed at http://www.csueastbay.edu/netid/self-service.html. Contact the ITS Service Desk at https://csueastbay.service-now.com/sp to submit a ticket or to speak with a technician. If you receive an email that you believe could be a phishing message, forward it to the Information Security Office at firstname.lastname@example.org.
No one from CSU East Bay will ask you for your password. Never give your password to anyone.
