It caused damage to the front of their home in Brantwood Gardens, Antrim shortly before 4am on Friday morning.
Police are investigating a motive for the attack but say they haven't ruled out paramilitary involvement.
A group claiming to be the Real UFF contacted the UTV newsroom claiming responsibility for the attack.
Detectives appealed for anybody in the area at the time to come forward.
They want to speak to two young men seen on bicycles. They also hope to speak to any milkmen who may have been in the vicinity.
Alliance South Antrim MLA David Ford has condemned the attack.
"This pipe bomb endangered the lives of those in the house at the time as well as their neighbours. This type of attack is a relic of the past, which is where it belongs," he said.
"I am concerned that there was allegedly paramilitary involvement in this attack.
And I would urge anybody with any information about this attack to contact the police."
Meanwhile police are treating a separate fire bomb attack at a GAA hall, also in Antrim, as a hate crime.
A window was broken at the hall in Armoy overnight and flammable liquid poured inside and set alight, causing scorch damage.
