Questel SAS
● Listed in the last 48hAbout the organisation
Over 21 million Salesforce records containing some PII and 147GB+ of internal corporate data was compromised. This is a final warning to reach out by 4 August 2026 before we leak along with several annoying (digital) problems that'll come your way. Make the right decision, don't be the next headline.
What the listing means
Questel SAS appeared on the shinyhunters leak site on 02 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 01 August 2026, 1 day before the listing. This group has published 6 claims in the last 30 days and remains active.
Recommended actions
- Treat any unsolicited message referencing Questel SAS as suspicious — leaked data gets weaponised for phishing within days.
- If you hold an account on questel.com, change that password now, update it anywhere you reused it, and enable two-factor authentication.
- 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.
