Polish authorities have arrested three Ukrainian citizens after discovering sophisticated hacking equipment, including FLIPPER devices, during a routine traffic stop in Warsaw.
The discovery marks a significant operation targeting cybercriminals allegedly traveling across Europe and conducting cyberattacks against critical infrastructure.
Officers from Warsaw’s Śródmieście district stopped a Toyota sedan on Senatorska Street. They found three men, aged 43, 42, and 39, who exhibited suspicious behavior during questioning.
The vehicle contained an alarming arsenal of cyber tools designed to compromise IT and telecommunications networks.
Authorities seized advanced FLIPPER hacking equipment, spyware detection devices, multiple SIM cards, encrypted hard drives, routers, antennas, laptops, and cameras.
The suspects claimed to be IT specialists traveling throughout Europe, but their evasive responses and inconsistent statements raised immediate red flags.
When questioned in detail, the men showed limited English-language abilities. They pretended not to understand further inquiries, demonstrating potential guilt and awareness of their illegal activities.

The Warsaw Central Bureau for Combating Cybercrime immediately examined the seized equipment.
While the data storage devices were heavily encrypted, cybersecurity specialists successfully extracted evidence from the equipment, revealing crucial information about their operations.
Investigators determined the men had arrived in Poland only hours before their arrest and planned to continue to Lithuania, suggesting an organized criminal network operating across multiple European nations.
The suspects faced charges including fraud, computer fraud, and possession of devices specifically adapted for committing crimes, including the potential for damage to computer systems critical to national defense.
The District Prosecutor’s Office of Warsaw Śródmieście-Północ presented compelling evidence to the court, which granted a three-month pretrial detention order for all three defendants.
This case highlights the ongoing threat from sophisticated cybercriminals targeting European infrastructure.
Polish authorities continue investigating when and why these individuals entered Poland, examining whether they conducted successful cyberattacks before their apprehension.
The operation demonstrates law enforcement’s commitment to protecting critical national systems from international cyber threats.
The investigation remains ongoing under the supervision of the District Prosecutor’s Office of Warsaw Śródmieście-Północ, with additional charges potentially forthcoming as evidence analysis continues.
