Disclosure context

About Icarus

Based on available threat intelligence, Icarus is an emerging ransomware group first observed in May 2026 with limited documented activity to date. The group appears to be in early operational stages with only one confirmed victim reported in public security advisories. Icarus has demonstrated targeting focus on Indonesia's financial services sector, suggesting either regional operational preferences or specific expertise in compromising financial institutions within Southeast Asian markets. Due to the group's recent emergence and minimal public reporting from established threat intelligence sources, detailed information regarding their specific attack methodologies, initial access vectors, encryption techniques, or organizational structure remains undocumented by major security research firms or government agencies. No confirmed attribution to specific threat actors, state sponsorship, or connections to established ransomware-as-a-service operations has been reported by CISA, FBI, or leading cybersecurity organizations. The group's current operational status remains unclear given the limited intelligence available, though their recent emergence suggests they may still be active or in developmental phases of their ransomware operations. The group has been linked to 11 public disclosures across our corpus. First observed on a leak site on May 5, 2026; most recent post June 23, 2026. The operation is currently active.

If your organisation is affected

A listing by Icarus means Cazh.id 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.
Monitor for the data appearing on Icarus'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.
