Attack summary

Severity: critical — JAXA is a government-linked national space and aerospace agency with defence-adjacent responsibilities; 6.9 TB of exfiltrated data from such an entity represents a critical national security and regulated-data exposure risk, including potential leakage of sensitive aerospace, satellite, and dual-use research data.

The group ALP-001 claims to have exfiltrated 6.9 TB of data from JAXA, with the full dataset reportedly ready for publication; the post indicates a disclosure deadline of 2026-04-05 and lists revenue of $367 million, suggesting the ransom demand is tied to the organisation's revenue figure.

Disclosure context

About ALP-001

ALP-001 is an emerging ransomware group first observed in March 2026 with limited documented activity, having targeted only five known victims to date with a focus on financially motivated cybercrime. Due to the group's recent emergence and low victim count, their country of origin, operational structure, and potential affiliations remain unknown with no public documentation from major security firms or law enforcement agencies regarding their organizational structure. Their attack methodology, encryption techniques, and initial access vectors have not been publicly analyzed or reported by reputable security researchers, though their targeting pattern suggests a preference for technology and manufacturing sectors across developed nations including the United States, Japan, China, France, and Italy. No notable campaigns, high-profile incidents, or significant ransoms have been publicly documented for this group, and no law enforcement actions have been reported against ALP-001. The group's current operational status remains unclear due to limited public intelligence and their recent emergence in the threat landscape. The group has been linked to 17 public disclosures across our corpus. First observed on a leak site on March 21, 2026; most recent post April 8, 2026. The operation is currently active.

If your organisation is affected

A listing by ALP-001 means jaxa.jp 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, JPCERT/CC (Japan), as required for your jurisdiction.
Monitor for the data appearing on ALP-001'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.
