On 10 August 1939, Reinhard Heydrich informed Naujocks of his mission to lead a small group of German operatives to seize the Gleiwitz radio station.
Three weeks later, on the night of 31 August, Naujocks led the attack on the German radio station at Gleiwitz, one of twenty-one similar concentrated attacks which the German government quickly attributed to the Poles.
Once inside the radio station, a short anti-German message in Polish was broadcast (the precise content of the message is now uncertain).
Shots were fired in the studio and a corpse left on the floor near the microphone.

To add documented proof of this attack, the SD operatives placed fictitious Polish troops (corpses of prisoners from the Dachau concentration camp who had been dressed in Polish uniforms provided by the Abwehr, killed by lethal injection, and then shot for the sake of appearances) around the attacked radio station for selected members of the press to see at the site of the incident.
These attacks, but not exclusively the Gleiwitz incident, formed Hitler's justification to the Reichstag regarding the necessary "pacification" of Poland, thereby igniting the Second World War in Europe.

More recently, author and researcher Jak Mallmann-Showell's investigation has suggested that Naujocks's claims as to his actions at the Gleiwitz radio station may have been a fabrication to curry special handling by the Allies after the war.
Mallmann-Showell discerned that Naujocks is the sole source for details of his personal actions on the night of 31 August 1939.
He also avers that the Poles may have accessed the site to obtain Enigma machine secrets for the allies.

Later, on 9 November 1939, Naujocks (along with Walter Schellenberg) participated in the Venlo incident, which saw the capture in the Netherlands of two British SIS agents, Captain Sigismund Payne Best and Major Richard Henry Stevens.

In early 1940, Naujocks was put in charge of the counterfeiting unit of the SD charged with forging British bank notes under Operation Andreas.
By late 1940 Naujocks had been removed from his position after he fell out of favor with Heydrich.

In 1941, he was dismissed from the SD after disputing one of Reinhard Heydrich's orders.
He was demoted and had to serve in the Waffen-SS on the Eastern Front.
In 1943, due to ill health, he was sent to the West, where he served as an economic administrator the following year for German troops in Belgium, while involving himself in the deaths of several Belgian underground and Danish resistance members.

After his promotion to Obersturmführer (first lieutenant) he participated in sabotage and terrorist actions against the Danish population from December 1943 until autumn 1944, as the leader of the "Peter Group", including the murder of Lutheran pastor Kaj Munk.
Later leadership passed to SS-Hauptsturmführer Otto Alexander Friedrich Schwerdt (SS-Jagdverbände).
Circa November 1944, Naujocks turned himself over to American forces, who subsequently placed him in detention as a possible war criminal by the end of the war.
