Dublin City University (DCU) is at the centre of an online scam that is trying to rip off its suppliers.
Gardai have launched an investigation into the internet fraudsters.
Suppliers reported that they had received emails purporting to be from the university's procurement department.
These were viewed as an attempt to fraudulently place orders for goods.
The fraudsters attempted to trick suppliers into giving out personal information by verifying account information
In an email to all suppliers on Thursday evening, DCU management warned of num- erous attempts to rip-off their suppliers and informed them that gardai had been notified.
The attempted frauds were confirmed by the university yesterday, but it would not comment on how much money the perpetrators tried to take.
The email issued by DCU warned: "We have been notified that some of our suppliers have received emails purporting to be from DCU's Procurement Department, in an attempt to fraudulently place orders for goods from those suppliers.
"We have spoken to An Garda Siochana about these incidents and will continue to do so if and when they arise.
"We have also reported the domains used to service providers, including the following domains from which our suppliers were targeted: dcu.ie.finance, dcu-ie.biz and dcu-ie.org."
The email advised suppliers to block certain email addresses and not to respond to or click on any of the links within the email and to delete the message immediately.
"We recommend that these domains be blocked by your IT staff in case they are reactivated at a later stage.
"We will update you with any future domains as we become aware of them.
"We are requesting all suppliers to exercise caution in relation to any suspicious emails or purchase orders.
"Please be aware that DCU would never place a purchase order without a valid DCU delivery address within the university or one of its campuses.
"Should you have any concerns about a particular purchase order, please contact the department placing it.
"Contact details of individuals can be obtained on DCU's website www.dcu.ie."
The email went on to advise suppliers that following verif- ication of attempted fraud, they should contact gardai and advise DCU (firstname.lastname@example.org) so that they can pass the information to their supplier base.
"We are actively working to investigate and resolve this situation and apologise for any inconvenience," DCU told suppliers.
