Disclosure context

About lunalock

LunaLock is a recently emerged ransomware group first observed in September 2025, appearing to be financially motivated based on their limited operational footprint. The group's country of origin and potential affiliations remain unknown due to their recent emergence and limited public documentation. With only two documented victims to date, LunaLock appears to primarily target telecommunications infrastructure, with attacks recorded in the United States and Mexico, though their specific attack methodology, encryption techniques, and whether they employ data exfiltration tactics have not been publicly documented by major security research organizations. No notable high-profile campaigns or significant ransomware demands have been reported for this group, and no law enforcement actions have been publicly disclosed. LunaLock appears to remain active as of late 2025, though their limited victim count and recent emergence make it difficult to assess their long-term operational capabilities or intentions. The group has been linked to 2 public disclosures across our corpus. First observed on a leak site on September 2, 2025; most recent post September 16, 2025. The operation is currently inactive.

Attack summary

Severity: medium — Data has been published by the group, indicating confirmed exfiltration beyond a mere listing. However, no specific data types, volume, or proof files are described in the post, and the company is a small regional ISP. Potential exposure of subscriber PII warrants medium severity, but insufficient detail prevents classification as high or critical.

The lunalock ransomware group claims an attack on JAFICA Telecomunicaciones and has published data ('data_published' status), though the leak post provides minimal detail on the nature of the exfiltrated data or whether encryption occurred. No ransom amount or specific data volume has been stated.
