Germany Warns of Escalating Russian Espionage

German Chancellor Friedrich Merz has warned that Germany faces intensive espionage activity, following the arrest of a Ukrainian national suspected of spying for Russia. The suspect, identified under German privacy law as Vadym Y., allegedly gathered military-related information, including details about the production of armoured vehicles, ammunition and explosives. Prosecutors say he had been in contact with a Russian intelligence service through an intermediary since at least July 2025. He is due to appear before an investigating judge. Merz described the investigation as a success but said Russian intelligence activity in Germany remains consistently high and predicted that more cases would emerge in the coming months and years. Germany has supplied weapons to Ukraine since Russia’s full-scale invasion in 2022, and a number of people suspected of working for Russia or other foreign powers have been arrested in Germany this year. The article also outlines other recent investigations. A woman was arrested in Berlin in January on suspicion of collecting information for a Russian intelligence officer. A Romanian woman and a Ukrainian man were accused of spying on someone supplying drones from Germany to Ukraine. Separately, former German spy chief August Hanning was arrested on suspicion of espionage, treason and obtaining classified information for a foreign power; investigators have not identified that power. A former BND employee, Manfred D., is accused of passing Hanning about 2,000 classified documents for money. Merz’s warning came as Germany and the UK have been discussing security cooperation, including responses to hybrid attacks and hostile activity. The talks followed Germany’s accusation that Russia launched an explosive-equipped drone at Leipzig/Halle Airport in September. Russian President Vladimir Putin denied the accusation and accused Germany of planting evidence.

German authorities have arrested a Ukrainian man in Brandenburg on suspicion of spying for Russia, according to the Federal Public Prosecutor’s Office in Karlsruhe. The suspect, identified by prosecutors as Vadym Y., is accused of using connections to European defense companies to collect information and pass it to a Russian intelligence service. Prosecutors say he had been in contact with an intermediary since July 2025 and gathered information in Germany related to Russia’s full-scale invasion of Ukraine. The alleged intelligence included details about the production of armored vehicles, ammunition and explosives, as well as information about personnel and military facilities at sites intended to protect NATO’s eastern flank. The suspect was expected to appear before a judge on Friday. The arrest comes amid heightened concern in Germany about Russian espionage, sabotage and other forms of disruption, often described as a “hybrid” campaign. The article points to the discovery of an explosive-laden drone near a Ukrainian cargo plane at Leipzig airport; Berlin attributed the attempted attack to Moscow. It also notes that Germany has arrested people in other cases involving suspected Russian espionage, while Moscow has denied the allegations. Germany is a major military and political supporter of Ukraine. Chancellor Friedrich Merz said he was not surprised by the latest arrest and anticipated further cases. In response to the perceived threat, Germany has expanded the powers of its foreign intelligence service, the BND. Its chief, Martin Jaeger, told lawmakers that Russia’s “shadow war” was escalating and becoming more dangerous. He warned that Germany risked being drawn into a violent conflict with Russia.

German authorities have arrested a Ukrainian national in Brandenburg on suspicion of spying for Russia, the Federal Public Prosecutor’s Office in Karlsruhe announced. Prosecutors allege that the suspect, identified as Vadym Y., had been in contact with a Russian intelligence service through an intermediary since at least July 2025. In the context of Russia’s war against Ukraine, he is suspected of gathering militarily relevant information in Germany for that service. The information allegedly concerned the production of armoured vehicles, ammunition and explosives, as well as personnel and military facilities at locations involved in protecting NATO’s eastern flank. Prosecutors say some information was publicly available, while the suspect allegedly sought other details by approaching people working in the European defence industry. The investigation into suspected activity as an intelligence agent is ongoing; prosecutors have not established the full circumstances or whether other people were involved. The article places the arrest amid warnings from German security authorities about suspected Russian espionage and sabotage. It describes two other cases: an April 2026 arrest in Berlin involving allegations that a man passed information about German military support for Ukraine, defence companies and military convoys to Russian intelligence; and a case involving a 53-year-old Ukrainian man accused of monitoring another Ukrainian in a refugee shelter for Russia’s FSB and sharing information about that person’s contacts via Telegram. Charges have been brought in the latter case. The article notes that the cases involve different allegations but demonstrate the range of German investigations, from military information gathering to surveillance of individuals of interest to Russia. It stresses that the Brandenburg investigation is still underway and that the accused is presumed innocent unless convicted.

A Ukrainian national identified by German federal prosecutors as Vadym Y. has been arrested in the state of Brandenburg on suspicion of spying for Russia. Prosecutors allege he had been in contact with a Russian secret service through an intermediary since at least July 2025. They say he collected military-related intelligence about the production of armoured vehicles, ammunition and explosives, as well as personnel and installations involved in protecting NATO’s eastern flank. Some of the information was publicly available, while other details were allegedly sought from people in Europe’s defence industry. The Russian embassy in Berlin had not responded to a request for comment at the time of publication. The arrest comes as Germany steps up efforts to counter what it regards as escalating Russian hybrid attacks. Chancellor Friedrich Merz said the arrest did not surprise him and warned that more cases could follow. Western officials have also warned of Russian sabotage, cyber activity and other hybrid operations across Europe, which they say aim to weaken support for Ukraine. Merz described Russian disinformation and hybrid operations as the greatest threat to Germany’s security and said Moscow was challenging the post-Cold War political order. The suspect is scheduled to appear before an investigating judge at Germany’s Federal Court of Justice. The judge is to formally present the arrest warrant and decide whether the suspect will remain in pre-trial detention. The allegations are presented as prosecutors’ claims; the article does not report a conviction.
