Based on the limited public documentation available, networm is an obscure ransomware group that first emerged in May 2021, appearing to operate with financial motivations typical of ransomware actors. The group's origin and affiliations remain largely unknown to security researchers, with insufficient evidence to determine whether they operate as a Ransomware-as-a-Service model or as an independent entity. Due to the minimal public reporting from major cybersecurity firms and law enforcement agencies, specific details about networm's attack methodology, initial access vectors, and encryption techniques have not been widely documented. The group appears to have conducted at least one documented attack targeting the commercial facilities sector in Israel, though comprehensive analysis of their tactics, techniques, and procedures remains limited. Given the sparse intelligence available and lack of recent reporting from established threat intelligence sources, the current operational status of networm is unclear, with the group potentially having ceased operations, rebranded, or maintained a very low profile since their initial observation. The group has been linked to 1 public disclosures across our corpus. First observed on a leak site on May 2, 2021. The operation is currently inactive.

This disclosure adds to ransomware activity in the Commercial Facilities sector, which has 21 disclosures indexed across all operators we track. Geographically, H&M Israel is reported in Israel, a country with 156 ransomware disclosures in our corpus.
If your organisation is affected
A listing by networm means H&M Israel appeared on a ransomware extortion site and data attributed to it has been published. If this is your organisation, or a supplier you depend on, the priority is to confirm the intrusion and contain it before the window to act closes.
- Engage your incident-response team and preserve forensic evidence before remediating — do not wipe affected systems first.
- Force a password reset and revoke active sessions for exposed accounts; rotate any credentials, API keys or certificates that may have been in the stolen data.
- Assess regulatory notification duties (GDPR, NIS2, sector regulators) — many carry a 72-hour reporting clock from awareness.
- Report the incident to your national CERT, CERT-IL (Israel), as required for your jurisdiction.
- Monitor for the data appearing on networm's leak site and across paste and breach channels, and brief downstream partners who may be exposed through you.
How we know this. Darkfield monitors public ransomware leak sites continuously, archiving every new disclosure and the data later released against the victim. Each entry on this page is sourced from the operator's own publication and cross-checked against complementary OSINT feeds (RansomLook, ransomware.live, RansomWatch). We do not collect or host stolen data — only the metadata, timestamps and screenshots needed to make the public disclosure searchable and accountable. Records here are corrected when the original post is edited, retracted, or merged with another disclosure.
