The chilling caption reads “We will terrorise you in cyber space and a real world”.
The poster was shared on Twitter and appears to have come from the “Cyber Attack Foundation”.
It comes as a quick follow up threat to one from earlier this month, where the shocking poster shows a suited man is seen holding a huge knife behind his back behind a crowd of cheering young music fans.
The poster is credited to Remah Media and was being circulated all across Europe.
The chilling online poster warned of a deadly knife attack at pop and rock concerts.
The caption to the photo – which has been posted on Twitter – reads: "Wait for our surprises" and it is signed "Islamic State".
The threat comes in the wake of high-profile terror attacks at concerts in the UK and in France – which left dozens dead and many more injured.
Earlier this year we revealed how pro-ISIS fanatics also issued a chilling terror threat to the city of Manchester just one year after 22 were murdered at an Ariana Grande concert.
They posted a picture of a jihadi lurking on the city's streets.
It was sent out by one of the Islamist death cult's propaganda wings.
Emergency services rushed to the scene after the bomb blast in Manchester.
The poster shows a bearded man wearing a baseball cap and a hoodie as he stands on a street corner in the Ancoats area of Manchester – close to the city centre.
Behind him lays a dead body on the pavement and the poster warns: “We will fulfil our promises to you.”
Manchester-born jihadi Salman Abedi struck with a home-made suicide bomb at the Ariana Grande concert at Manchester Arena in May last year.
The explosive detonated moments after US pop star Ariana left the stage, sending nuts and bolts flying as young fans made their way out of the venue.
At least 64 people were injured in the horror blast with 22 gig-goers killed.
