roamingnetworks.rs Listed by lockbit5 Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
roamingnetworks.rs was listed by the lockbit5 ransomware group on March 30, 2026, with internal files reported as exfiltrated. Anyone connected to the organisation should check whether their data is involved and take appropriate protective steps.
Inside the incident
The only confirmed detail is the March 30, 2026 listing itself. The group claims internal files were taken, but no further description of the intrusion method, duration, or scope has been made public. The number of people or records involved remains unknown.
Who is lockbit5?
Lockbit5 is a ransomware operation that has conducted multiple campaigns since at least 2019. The group typically gains initial access through phishing or compromised remote-access services, then deploys encryption and exfiltrates data before demanding payment. Its listings on dedicated leak sites serve as a pressure tactic when victims do not meet ransom demands. Prior activity attributed to the group has included attacks on organisations in multiple countries and sectors.
Who is roamingnetworks.rs?
Roamingnetworks.rs is associated with Dot Networks, an organisation active since 2008. Companies in this sector provide telecommunications and network services, including roaming infrastructure that supports connectivity between mobile operators. Such entities routinely handle configuration data, partner agreements, and operational records necessary to maintain service between networks.
What data was at risk
The listing refers only to “internal files.” No inventory of specific data categories has been published. Organisations that operate network and roaming services commonly store technical configuration details, customer or partner identifiers, and internal correspondence, but the precise contents of the exfiltrated material have not been confirmed.
Why it matters
Even without a confirmed count of affected individuals, exposure of internal operational files can create downstream risks for partner organisations and end users whose connectivity depends on the affected systems. For the organisation, the incident adds operational disruption and potential regulatory scrutiny common to network-service providers.
If your data was in this claimed breach

Individuals can run a free exposure scan of their email address against known breach data to check for prior appearances of their information.

Breach listings — particularly those originating from ransomware or leak sites — are third-party claims that may be unverified, incomplete, or inaccurate. A listing does not by itself confirm that a breach occurred or that any specific data was exposed. Severity is an automated assessment, not a definitive rating. Verification status is shown where available.
