The French interior minister Bernard Cazeneuve made the claim as he argued for the creation of a special task force to travel to Greece to help clamp down on stolen or fake passports.
At least two of the ISIS terrorists who launched a murderous attack in Paris in November used established migrant routes through Europe pretending to be refugees and using Syrian passports.
According to the Wall Street Journal, Cazeneuve told reporters: 'Daesh has managed to seize passports in Iraq, Syria and Libya and to set up a true industry of fake passports.'
Last month, US authorities revealed their concerns that ISIS may have obtained a passport printing machine in an attempt to infiltrate the West through using false documents.
It emerged after a 17-page Homeland Security Investigations (HSI) intelligence report was publishing, warning of the use of false passports, according to ABC News.
'Since more than 17 months [have] passed since Raqqa and Deir ez-Zour fell to ISIS, it is possible that individuals from Syria with passports 'issued' in these ISIS controlled cities or who had passport blanks, may have traveled to the U.S,' claimed the report.
The report was based on a source of 'moderate confidence', suggesting that ISIS's printing of passports is in no way confirmed.
Questions remain over why ISIS would need to spent time painstakingly falsifying documents when they have a large horde of foreign fighters available.
At least two men involved in the deadly Paris attacks are suspected to have used false Syrian passports to illegally enter Europe.
The forged documents were found at the scene of one of the suicide bomb attacks at the Stade de France, further fueling speculation that ISIS may have a ready source of blank passports.
Some analysts at the time of the attacks suggested that the discovery of the Syrian passports was in no way conclusive that the terrorists had used them to enter Europe.
The documents may have been deliberately planted to stir up hatred and distrust towards migrants, particularly refugees fleeing the war in Syria.
The ease in which it is possible for someone to get a Syrian passport was revealed by MailOnline reporter Nick Fagge, who bought an identical false Syrian passport as part of an investigation into the illegal printing of Syrian identity documents.
At the time of obtaining the false documents in September, MailOnline was warned by a forger that ISIS terrorists were already using fake passports to travel outside of Syria and Iraq.
A German police analysis of the Syrian passport bought by MailOnline confirmed that the book was genuine, allowing the forger to easily fill in the details on the blank pages.
