What the listing means
Daechang Solution appeared on the Black X leak site on 13 June 2026. Groups publish a victim once negotiations stall or as pressure during them, so a listing usually means data was already exfiltrated β the attack itself is dated 08 June 2026, 5 days before the listing. This group has published 1 claim in the last 30 days and remains active.
Recommended actions
- Treat any unsolicited message referencing Daechang Solution as suspicious β leaked data gets weaponised for phishing within days.
- If you hold an account on dsol.co.kr, change that password now, update it anywhere you reused it, and enable two-factor authentication.
- Other Business Services 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 β check the organisation's own disclosures before acting on it.
