A statement by FBR here Wednesday denied any association with these emails being sent from a fake email address 'do-not- reply@fbrgovpk.com' which has no connection with FBR's email domain.

These fake emails inform the targeted tax payers the tax returns filed by them do not match their sources of income and further advise them to contact the Commissioner Inland Revenue at the earliest.

These emails also reportedly carry attachments infected by harmful viruses and malware, the statement added.

This nefarious activity apparently by some hackers is a type of spamming used to send viruses and malwares to the general public and taxpayers.

The taxpayers and the general public are advised to ignore such fake emails and refrain from clicking any link provided in them, the statement said adding the receipt of such fake emails should be immediately reported to the authorities concerned.
