lastpass two related security incidents were disclosed by the password manager lastpass in 2022 in the first incident an attacker accessed parts of lastpass s development environment and exfiltrated source code repositories and technical documentation including an encrypted copy of the key used to protect backups of customer data stored in amazon s3 in a second incident a senior devops engineer s personal computer was compromised and the attacker used a keystroke logger to obtain the employee s credentials and access an internal vault holding further keys according to the uk information commissioner s office ico this enabled access to and exfiltration of a backup database and copies of some customers password vault data which included both unencrypted fields such as some website urls and encrypted fields such as usernames and passwords the breach prompted litigation and regulatory scrutiny including a monetary penalty issued by the ico in november 2025 against lastpass uk ltd for failures to implement appropriate technical and organisational measures affecting over one million uk data subjects the breach led to further incidents because stolen vault backups can be subjected to offline cracking attempts in 2025 lastpass settled a class action lawsuit in the amount of 24 5 million for losses incurred by customers whose vaults had been accessed background edit lastpass stores users credentials in encrypted vaults at the time of the incidents lastpass operated its production environment in physical data centres and used amazon s3 buckets for backup storage it secured those backups using server side encryption with a sse c key a the sse c key was always encrypted when not in use and only four people at lastpass were able to decrypt the key itself 1 15 during the relevant period lastpass permitted employees to link personal and employee business lastpass accounts under a single master password 1 15 attack timeline edit between 8 and 11 august 2 2022 an attacker compromised the laptop of a software developer at lastpass and downloaded 14 of lastpass s source code repositories 1 16 along with technical documentation and an encrypted version of the sse c key 2 that secured the backups of lastpass s production database inside aws s3 buckets 1 15 however the attacker would not have been able to decrypt the key lastpass refers to this as incident 1 2 on 11 august 2022 an aws guardduty alert was triggered and sent to the lastpass security operations centre 1 15 on 12 august 2022 the personal computer of a different lastpass employee a senior devops engineer according to lastpass 3 who was one of the four people who had access to the decryption key for the sse c key was compromised by an attacker b via a plex server the employee was running the plex server had not been updated to cover a critical vulnerability the attacker gained full access to the employee s machine and used a keystroke logger to obtain that engineer s master password 1 19 lastpass refers to this as incident 2 1 18 on 13 august 2022 lastpass hired the u s cybersecurity firm and subsidiary of google mandiant to help them respond to the incident 1 16 between 16 and 18 august lastpass rotated any clear text credentials or secrets that may have been accessed by the incident 1 attacker along with the aws access keys 1 18 on 20 august after lastpass had rotated their keys the attacker extracted the contents of the senior devops engineer s employee business account vault containing the keys 1 18 between 20 august and 16 september 2022 the actor obtained the user database of 14 august 2022 and several password vault backups 1 19 on 25 august 2022 lastpass released a statement that it had detected unusual activity in portions of its development environment and that it had seen no evidence of access to customer data or encrypted vaults while reporting that source code and proprietary technical information had been taken 4 on 15 september 2022 lastpass said its investigation with mandiant revealed that the threat actor s activity was limited to a four day period in august 2022 with no evidence of activity beyond the timeline and no evidence of access to customer data or encrypted vaults 4 the ico later said that lastpass had actually been unable to determine the extent of the issue because of a combination of anti forensic activity by the attacker and a scheduled os upgrade coinciding with incident 1 1 16 2 on 15 and 22 october 2022 activity by the attacker triggered aws guardduty alerts but due to errors in the setup of the mailing list and a miscommunication between teams the lastpass security operations centre were not made aware of the alerts until 2 november 1 20 on 30 november 2022 lastpass contacted the ico with a personal data breach report 1 21 on 15 december 2022 aws confirmed to lastpass that the threat actor had downloaded a copy of the backup database 1 20 impact edit the stolen information included unencrypted names email addresses billing addresses partial credit cards and website urls 1 27 it also included the password vaults that were encrypted with users master passwords 1 14 the information commissioner s office found that over one million uk data subjects were affected 1 27 the security of each user s encrypted password vault depends on the strength of the user s master password or whether the password had previously been leaked and the number of rounds of encryption used some customer vaults were more vulnerable to decryption than others because they were older and lastpass had increased the minimum amount of encryption rounds over time 5 6 in september 2023 krebs on security reported some stolen lastpass vaults were being successfully decrypted in offline attacks researchers had linked thefts affecting more than 150 victims totalling more than 35 million and described a common factor among victims as having stored cryptocurrency seed phrases in lastpass lastpass declined to answer questions about the research citing an ongoing law enforcement investigation and pending litigation 7 8 9 in 2025 a larger heist of 150 million was also linked to the 2022 data theft 8 legal consequences edit on 20 november 2025 the information commissioner s office ico issued a penalty notice to lastpass uk ltd under section 155 of the data protection act 2018 requiring it to pay 1 228 283 for infringements of article 5 1 f and article 32 1 of the uk gdpr 1 the ico concluded that during the period 31 december 2021 to 31 december 2024 lastpass hadn t implemented expected technical and organisational measures including by allowing senior employees to use employee business accounts from personal devices and by permitting personal and employee business accounts to be linked under a single master password it found that these failings contributed to the unlawful access and exfiltration of personal data relating to approximately over a million uk based customers 10 in announcing the enforcement action information commissioner john edwards said that lastpass customers had a right to expect the personal information they entrusted to the company would be kept safe and secure 11 the fine had been reduced by 30 to reflect the measures that lastpass had in place at the time and put into place afterwards 1 79 a class action lawsuit was initiated in early 2023 with the anonymous plaintiff stating that lastpass failed to keep users information safe 12 of particular concern in the lawsuit was the increased risk of the details being used in phishing attacks 12 in november 2025 the parties informed the court that they had reached an agreement in principle 13 and it was reported in february 2026 that the settlement was in the amount of 24 5 million with 16 million of that set aside specifically for loses related to cryptocurrency 14 notes edit sse stands for server side encryption and the c denotes that it is customer held it is unknown if the whole attack was by one person a group or several attackers who sold each other information references edit 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 penalty notice lastpass uk ltd pdf information commissioner s
