The Department of Education (DepEd) Ilocos Sur Division warned the public against transacting with the office via Facebook after its account was hacked.
"Please be extremely cautious of any messages or requests coming from this page until further notice. Do not click on any links or provide any personal information in response to any suspicious communication," it said.
For now, the public may visit the office in person for official business.
DepEd has already sought assistance from the Ilocos Sur Provincial Cyber Response Team Office on the matter.
