Disclosure context

About pear

The Pear ransomware group is a relatively new threat actor that emerged in August 2025, operating with primarily financial motivations and targeting victims across multiple countries and sectors. Based on their recent emergence and limited public documentation, specific details about their country of origin and organizational structure remain unclear, though their targeting patterns suggest a financially-driven operation that may operate independently or as part of a smaller ransomware-as-a-service model. With 65 documented victims since their August 2025 debut, the group has demonstrated a preference for targeting organizations in the United States, New Zealand, Australia, Egypt, and Switzerland, with particular focus on healthcare, business services, manufacturing, and technology sectors. Their attack methodology and specific technical details have not been extensively documented by major threat intelligence firms or law enforcement agencies, though their rapid victim acquisition suggests they have established effective initial access and encryption capabilities. Notable campaigns and high-profile attacks have not been publicly detailed by CISA, FBI, or major security research organizations, likely due to the group's recent emergence and relatively small scale compared to established ransomware operations. As of late 2025, Pear appears to remain active given their recent emergence and ongoing victim targeting across multiple geographic regions and industry verticals. The group has been linked to 110 public disclosures across our corpus. First observed on a leak site on August 5, 2025; most recent post August 15, 2026. The operation is currently active.

If your organisation is affected

A listing by pear means Sonitor appeared on a ransomware extortion site and is being pressured to pay before any publication. 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.
Monitor for the data appearing on pear'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.
