Nexus IT has closely followed an incident involving LastPass, a commonly used password management tool for businesses and consumers. The incident began in August 2022 and LastPass posted updates to their blog in November and December of 2022.
A threat actor gained access to a cloud storage container that stored backups of individuals’ data. LastPass detailed what was compromised in their most recent December post.
..basic customer account information and related metadata including company names, end-user names, billing addresses, email addresses, telephone numbers, and the IP addresses from which customers were accessing the LastPass service. The threat actor was also able to copy a backup of customer vault data from the encrypted storage container which is stored in a proprietary binary format that contains both unencrypted data, such as website URLs, as well as fully-encrypted sensitive fields such as website usernames and passwords, secure notes, and form-filled data.
We have determined that an unauthorized party, using information obtained in the August 2022 incident, was able to gain access to certain elements of our customers’ information. Our customers’ passwords remain safely encrypted due to LastPass’s Zero Knowledge architecture.
LastPass only gave vague details in November and previously insisted in August that customer data was not at risk. Nexus IT did not feel it was necessary to take on LastPass’ responsibility to inform customers of the incident until their latest post.
To put it briefly, yes. Some personal information was exposed as LastPass indicated (customer names, billing addresses, email addresses, phone numbers, URLs, and IP addresses). As our security partner Sophos put it, “Loosely speaking, the crooks now know who you are, where you live, which computers on the internet are yours, and how to contact you electronically.”
For assistance or additional details of the incident, one of our expert cybersecurity consultants would be happy to help!
