03The ICO's own account
£1,228,283 penalty issued to password management provider LastPass UK Ltd on 20 November 2025 in respect of infringements of Article 5(1)(f) and Article 32(1)(f) UK GDPR. LastPass' failure to implement appropriate technical and organisational security measures allowed a threat actor to exfiltrate personal data relating to approximately 1.6 million UK customers from its backup database. However, due to LastPass' "zero knowledge" encryption system, the most sensitive personal data stored in LastPass customers' password vaults remained encrypted at all times, even after exfiltration by the threat actor.

GDPRFine.com is an independent tracker of ICO enforcement. It is not affiliated with, endorsed by or connected to the Information Commissioner's Office, and it uses no ICO branding. Where the ICO's own wording is reproduced it is quoted and attributed; everything else on these pages is our own summary of the published record.
The ICO's register held 222 entries on that date. 6 of them are prosecutions of named individuals, with ages and home towns in the ICO's own summary. This tracker indexes organisations, so those 6 are excluded and every count on these pages is out of 216. They remain on the ICO's own register.
An entry says what the Commissioner did on the date shown. It is not a statement about the organisation today, and the ICO can amend or remove a register entry at any time. Amounts and provisions are as published by the ICO; where the published notice does not state a figure or name a provision, these pages say so rather than filling the gap.
