The BBC has reported on research carried out by YouthSight on behalf of the Student Loans Company about the risks of online phishing to university freshers.
Freshers are being warned their student loans could be stolen if they reveal too much information on Facebook.
The Student Loans Company says fraudsters target unwitting first-year students who give personal details on social networking sites.
An online survey of more than 1,100 university applicants suggests many will invite new people they meet to be Facebook friends.
And two-thirds reveal personal details that could aid thieves.
Fraudsters sometimes try to hack into bank accounts by sending convincing-looking emails which ask for specific personal details. This is known as phishing.
