● Listed in the last 48hAbout the organisation
About Mayco International At least 2Tb of sensitive data were exfiltrated from the company’s control following a cyberattack. The compromised dataset leaked from Mayco internatioins company infrastructure includes internal organizational documents, proprietary technical schemas, employee personally identifiable information, and a substantial volume of financial records.
What the listing means
Mayco International appeared on the Dark Project leak site on 05 August 2026. Groups publish a victim once negotiations stall or as pressure during them, so a listing usually means data was already exfiltrated — the attack itself is dated 31 July 2026, 4 days before the listing. This group has published 7 claims in the last 30 days and remains active.
Recommended actions
- Treat any unsolicited message referencing Mayco International as suspicious — leaked data gets weaponised for phishing within days.
- If you hold an account on www.maycointernational.com, change that password now, update it anywhere you reused it, and enable two-factor authentication.
- Other Manufacturing 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 — check the organisation's own disclosures before acting on it.
