Unverified claim.
This entry reproduces a listing published by the qilin group on its own extortion site.
Attackers routinely exaggerate or fabricate victims. Nothing here confirms that
Musashino University suffered a breach, or what data was actually taken.
What the listing means
Musashino University appeared on the qilin leak site on 29 June 2026. Groups publish a victim once negotiations stall or as pressure during them, so a listing usually means data was already exfiltrated โ the attack itself is dated 16 June 2026, 13 days before the listing. This group has published 118 claims in the last 30 days and remains active.
Recommended actions
- Treat any unsolicited message referencing Musashino University as suspicious โ leaked data gets weaponised for phishing within days.
- If you hold an account on www.musashino-u.ac.jp, change that password now, update it anywhere you reused it, and enable two-factor authentication.
- Other Education organisations should review this group's known TTPs and validate detection coverage against them.
- Watch for follow-on extortion: stolen data is often re-leaked or resold after the initial listing.
- A leak-site listing is a claim made by the attacker, not a confirmed breach โ check the organisation's own disclosures before acting on it.
