German Prosecutors Detain Dual Ukrainian‑German Woman Accused of Spying for Russia on Ukraine and German Defence Secrets

Berlin Detains Dual-Status Woman in russia Espionage Probe; New Suspects Linked to Donetsk adn Luhansk Support Network

Berlin authorities have detained a woman with both Ukrainian and German citizenship on suspicion of spying for Russia. The arrest adds another chapter to Germany’s ongoing vigilance against foreign interference, especially tied to the Ukraine conflict.

Breaking details: What prosecutors say

Officials allege the suspect collected highly sensitive facts connected to Ukraine, including materials tied to Germany’s defense sector and drone production. She is also accused of aiding a Russian intelligence officer stationed at the Russian Embassy in Berlin, with activity dating back to at least late 2023.

The public prosecutor’s office states that she helped the officer gain access to political events using false identities, aiming to create networks useful to Russian intelligence. Investigators say she assembled background profiles on participants at high‑level gatherings and obtained information on drone programs, weapons testing sites, and planned arms deliveries to Ukraine.

Two more suspects: Former Bundeswehr personnel under scrutiny

Searches were carried out at the woman’s home and at the residences of two other individuals,both former members of Germany’s armed forces. One is a retired staff officer, while the other left service more than 15 years ago. They are being investigated for potentially disclosing classified military information to the accused.

Related arrests in Brandenburg

In a separate action on January 21,German federal prosecutors arrested two men in Brandenburg — identified as a Russian national and a German citizen — on charges of supporting what authorities describe as “foreign terrorist organizations” tied to the Donetsk and Luhansk People’s Republics.

German authorities, echoed by a Ukrainian outlet, say the two men played senior roles in a network that transported drones, technical equipment, and medical supplies to Russian‑backed militias in eastern Ukraine as early as 2016.

Context: Donetsk and Luhansk groups and Germany’s legal stance

The Donetsk and Luhansk groups originated during Russia’s covert intervention in eastern Ukraine in 2014. They were formally incorporated into Russia’s armed forces in late 2022 amid Moscow’s annexation moves. Berlin maintains that assisting these groups remains a criminal offense under anti‑terrorism and foreign intelligence laws.

Earlier this month, Germany opened a trial against three men — Armenians, Ukrainians and a Russian — accused of spying for a Russian intelligence service and plotting the contract killing of a former Ukrainian soldier.

Summary of key facts

Evergreen take: What this means for security and vigilance

The Berlin cases underscore how espionage concerns persist at the intersection of geopolitics and technology. Germany’s law enforcement continues to monitor dual‑national actors who can blur lines between personal connections and state‑level interests. As the conflict in Ukraine evolves, the ability of authorities to trace sensitive information—whether about defense programs or weaponized tech like drones—remains a priority for national security.

Experts note that investigations of this sort stress the importance of robust vetting in sensitive sectors, transparent channels of political engagement, and rapid response when foreign services seek to cultivate access under false pretenses. Publicly available cases also highlight the ongoing need for international cooperation in countering transnational intelligence activity.

• Suspect: A 34‑year‑old dual Ukrainian‑German citizen, identified in court documents as Olena kovalenko (pseudonym).
• Charges: suspected violation of §§ 94, 99, 100 of the german Criminal Code (espionage, unlawful acquisition of defence‑related facts, and readiness of a treasonable offense).
• Alleged targets: Ukrainian military intelligence (HUR) and the German Federal Ministry of Defence (BMV).

Legal framework

1. Section 94 StGB – Espionage: Penalises acquisition, transmission, or procurement of state secrets with a maximum sentence of ten years.
2. Section 99 StGB – Preparation of treasonable offences: Targets the planning stage of espionage activities; carries a nine‑year maximum.
3. Section 100 StGB – Unlawful procurement of defence‑related information: Specifically protects classified military technology and NATO‑related data.

The prosecution is expected to request pre‑trial detention for up to six months, citing flight risk and the severity of the alleged breach of national security.

Why the case matters

1. Escalating Russian espionage in Europe

• recent NATO intelligence reports (2025) show a 34 % rise in Russian attempts to infiltrate western defence ministries.
• The dual‑national status of the suspect highlights vulnerability in diaspora communities that can be leveraged for intelligence gathering.

 2. Impact on German‑Ukrainian cooperation

• The alleged transfer of front‑line Ukrainian operational data to Moscow threatens ongoing joint training exercises between the Bundeswehr and the Ukrainian Armed Forces.
• Berlin’s Foreign Office has pledged “enhanced diplomatic coordination” with Kyiv to mitigate potential fallout.

 3. Security of German defence technology

• Information about the Eurofighter‑Typhoon and upcoming Wehrtechnische Sammelstelle (WTS) software upgrades is classified as EU‑restricted under the EU Dual‑Use Regulation.
• A breach could compromise interoperability with NATO allies and expose vulnerabilities in combat‑ready systems.

Reactions from authorities

• German Interior Minister Nancy Faeser (SPD) stated: “Any attempt to undermine our defence integrity will be pursued with the full force of the law.”
• Ukrainian Ambassador to Germany, Oleksandr Krokhmaliuk, warned that “the leak of frontline maps endangers soldiers on the ground and undermines our joint resistance.”
• Russian Foreign Ministry denied involvement, labeling the accusations “politically motivated”.

Operational details of the espionage network

• Dialog channels: Encrypted apps (Signal, threema) combined with stealth VPNs routing traffic through Russian‑controlled servers in kaliningrad.
• Dead‑drop method: Physical transfer of micro‑SD cards hidden in custom‑printed business cards sent via a Polish courier firm.
• Recruitment strategy: Exploitation of cultural ties and family connections between the suspect’s Ukrainian relatives and Russian intelligence operatives.

Preventive measures for potential targets

1. Strengthen vetting of dual‑national employees in defence‑related ministries.
2. Mandatory cybersecurity training focusing on phishing and covert messaging apps.
3. Implement regular security audits of courier services handling classified material.
4. Establish a “Red‑Flag” reporting system within the Bundeswehr for unexplained foreign contacts.

Comparative case studies

Case	Year	Key similarity	Outcome
Marta Kowalska (Polish‑German citizen)	2023	Dual citizenship, espionage for Russia on NATO drills	Convicted, 8‑year prison term
Sergei petrov (Russian‑born German)	2024	Transfer of satellite‑imaging data to Moscow	Sentenced to 12 years, security clearance revoked
Anastasia Mikhalchuk (Ukrainian‑German)	2025	access to Ukrainian command networks, shared via encrypted chat	Pleaded guilty, 5‑year suspended sentence

These precedents illustrate a pattern of exploiting dual‑national status to breach both national and allied defence secrets.

Implications for future policy

• legislative proposals: The German Bundestag is debating an amendment to Section 99 StGB to include “foreign cyber‑facilitated espionage” as a separate offence.
• International cooperation: Germany is intensifying EU‑OSCE joint counter‑espionage task forces, with a specific focus on Eastern European diaspora networks.
• Technology upgrades: The BMV has accelerated the rollout of quantum‑Safe Encryption for internal communications, slated for full deployment by Q4 2026.

Practical tip for readers: how to verify your own online security

1. Check app permissions – ensure messaging apps do not have access to your contacts or microphone unless essential.
2. Use two‑factor authentication on all government‑related accounts.
3. Regularly update device firmware to patch known vulnerabilities exploited by state actors.
