Disclosure context

About netrunner

Based on the limited publicly available information, netrunner is a relatively new ransomware group that first emerged in April 2026 with documented attacks against at least six organizations. The group appears to be financially motivated, targeting a diverse range of sectors including healthcare, consumer services, telecommunications, manufacturing, and agriculture across multiple countries including Japan, the United States, Jordan, Italy, and South Korea. Due to the recent emergence of this group and limited public reporting from established threat intelligence sources, detailed information about their country of origin, operational affiliations, specific attack methodologies, encryption techniques, or whether they operate as a Ransomware-as-a-Service model remains undocumented by major cybersecurity organizations such as CISA, FBI, or Mandiant. The group's targeting pattern suggests opportunistic victim selection rather than geopolitically motivated attacks, given the broad geographic and sectoral distribution of their documented victims. No major high-profile campaigns or significant law enforcement actions against netrunner have been publicly reported by reputable security researchers at this time. Given the group's recent emergence in 2026, current activity status and operational capabilities require further monitoring and analysis by the cybersecurity community. The group has been linked to 9 public disclosures across our corpus. First observed on a leak site on April 3, 2026; most recent post May 16, 2026. The operation is currently active.

Attack summary

Severity: high — GEG serves 500+ public administrations and manages critical TETRA radio communications infrastructure used by civilian and likely emergency/government bodies across Italy. Exfiltration of data from a critical communications provider with deep public-sector penetration poses significant national security and operational risk, warranting a high severity rating even absent confirmed PII volume figures.

The netrunner group claims to have both encrypted and exfiltrated data from GEG Telecomunicazioni. No ransom amount or data size has been specified, but the post indicates full 'Locked, Exfiltrated' status with access to data advertised.
