Major International Operation Targets SIM Box Criminal Network
Law enforcement agencies across Europe have dismantled what Europol describes as a “highly sophisticated” criminal network operating a cybercrime-as-a-service platform. According to reports, the international sting operation resulted in seven arrests and the seizure of massive technological infrastructure used to facilitate millions of fraudulent activities.
Operation SIMCARTEL Takes Down Extensive Infrastructure
Authorities from Austria and Latvia, working with Europol and Eurojust, coordinated the takedown codenamed “SIMCARTEL.” The operation targeted a criminal network that sources indicate was responsible for more than 3,200 documented cyber fraud cases across the two countries. During raids, investigators reportedly seized 1,200 SIM box devices, 40,000 active SIM cards, and dismantled five servers central to the operation.
Service Enabled Global Criminal Activities
The criminal network had created an online service providing telephone numbers registered in over 80 countries, according to Europol’s press release. This infrastructure allowed threat actors to create approximately 49 million malicious online accounts used for various forms of cybercrime. Analysts suggest the service effectively masked perpetrators’ true identities and locations while they conducted their illegal operations.
Europol released video evidence showing what they described as the “action day” in Latvia, where authorities breached facilities containing hundreds of thousands of SIM cards and related equipment. The scale of the operation, which authorities say is still being fully uncovered, enabled what the report states was “a multitude of serious crimes that would not have been possible at all without masking the perpetrators’ identities.”
Financial Seizures and Additional Takedowns
In addition to the physical seizures, authorities reportedly took control of two websites offering illegal services and froze suspect accounts containing €431,000 and $333,000. The criminal network’s activities ultimately led to total losses estimated at several million euros, according to the analysis of the operation’s impact.
Broad Spectrum of Criminal Activities Uncovered
Sources indicate the dismantled network facilitated numerous serious crimes including phishing, smishing, fraud, extortion, migrant smuggling, police officer impersonation, and distribution of child sexual abuse materials. The service’s infrastructure reportedly made these activities possible by providing anonymous communication channels that concealed the perpetrators’ actual locations and identities.
Collaborative International Effort
Europol confirmed it dismantled the network’s infrastructure with assistance from the Shadowserver Foundation, a cybersecurity nonprofit. In a statement on social media platform X, Shadowserver expressed pride in “supporting our Law Enforcement partners in another successful cybercrime disruption,” though the organization typically maintains a policy of not commenting directly on law enforcement activities according to their standard practice.
The operation represents part of the broader European Multidisciplinary Platform Against Criminal Threats (EMPACT), which focuses on EU crime priorities in four-year cycles. Current priorities reportedly include disrupting high-risk criminal networks, targeting cyberattack organizers, combating human trafficking, child exploitation, migrant smuggling, and financial crimes.
This takedown occurs amid broader global cybersecurity tensions and follows other significant technology developments affecting international security landscapes. The successful operation demonstrates how coordinated international efforts can disrupt sophisticated criminal networks operating across borders, according to analysts monitoring industry developments and related innovations in cybersecurity.
