The Kyiv Regional Prosecutor's Office has completed its pre-trial investigation into five people who allegedly kidnapped cryptocurrency entrepreneurs and extorted over $2.2 million at gunpoint in 2024 and 2025. Four of the five suspects are former police officers, two of whom held the rank of colonel and organized the group's criminal activities.
Who Was Behind the Scheme: Colonels and a Recruited Group
According to prosecutors, two colonels from the Main Police Department in the Autonomous Republic of Crimea and Sevastopol, along with a Kyiv-based police unit, created and led the organized group. Two additional officers and one civilian with prior convictions completed the five-member team. All participants were discharged from police service following their arrest in November 2025.
Charges include creating an armed gang, kidnapping, unlawful imprisonment, robbery, extortion, and illegal possession of controlled substances. The case has been forwarded to court, but as of May 29, 2026, formal charges have not yet been filed against any of the suspects.
Documented Episodes: How the Scheme Worked
Prosecutors described at least four documented cases. In each, the victim was tracked, abducted, and transported between multiple undisclosed locations. Suspects used official police vehicles and presented themselves as law enforcement officers throughout the crimes.
In one documented case, a victim in Kyiv was seized at gunpoint and forced to sign a document acknowledging a fictitious $5 million debt before being moved between locations and made to hand over real funds or crypto assets. The group communicated through encrypted messengers and maintained a clear division of roles across all operations.
Why Crypto Holders Are Targeted
Security researchers call these crimes wrench attacks. The logic is straightforward: crypto assets can be transferred instantly, across borders, with no intermediary, and are virtually impossible to recover after the fact. Unlike a bank wire, a Bitcoin transaction requires no third-party confirmation and cannot be frozen once sent.
Cybercrime consultant David Sehyeon Baek told Decrypt that crypto may be cryptographically secure, but that does not matter once violence, coercion, and forced agreements enter the picture. Physical pressure bypasses every technical protection a wallet can offer.
Wrench Attacks: A Global Pattern
The Kyiv case is not isolated. In March 2026, a Los Angeles jury convicted former LAPD officer Eric Halem after he and accomplices posed as police, entered a Koreatown apartment, handcuffed two victims, and transferred $350,000 in Bitcoin from a 17-year-old's account. That same month, attackers posing as police forced a couple in Versailles, France to transfer roughly $1 million in Bitcoin at knifepoint.
The common factor across cases: criminals impersonate law enforcement to reduce victim resistance. Using a real police badge or uniform adds one more layer to the same scheme, converting institutional authority into a tool for theft.
Risk Scale and Defensive Measures
The crypto market has no unified statistic on wrench attacks, but the number of documented cases grows alongside asset prices. Analysts note that publicly disclosing large crypto holdings on social media or at conferences raises the risk of becoming a target.
- Operational security: experts recommend against publicly disclosing the size of crypto holdings or the location of hardware wallets.
- Multisignature wallets (multisig) reduce the risk of a forced transfer by requiring authorization from multiple devices to send funds.
- Time locks: some wallets allow configuring transaction delays, giving time to react if access is forced under duress.
The Kyiv case is one of the first public instances in Ukraine where serving officers organized a physical crypto extortion scheme. The completion of the pre-trial investigation and referral to court means charges will be filed, and any conviction will set a precedent for similar cases in the country.
