Misconfigured Lenskart S3 Bucket Leaking Sensitive User & Staff.
Lenskart now ships over 10 million pairs of eyewear every year and has over 20 million app downloads, besides over 1,200 stores across India, Singapore, and Dubai.
In this blog post, we will discuss a recent incident involving a misconfigured Amazon S3 bucket that resulted in the exposure of personal identification information (PII) data. This type of data leak can have serious consequences for both individuals and organizations, and it is important for companies to be aware of the potential risks and take steps to prevent them.
The incident occurred when a startup left an S3 bucket containing PII data publicly accessible, allowing anyone to access and download the information. This type of misconfiguration is a common problem and can be easily avoided by following best practices and setting appropriate permissions on S3 buckets. In this case, the bucket was not protected by a password or other authentication method, and anyone with the link could view and download the data.
The impact of this incident can be significant for both the individuals whose PII was exposed and the startup itself.
It was possible to download invoice with all kind of data like address, mobile number, invoice details. Scary !
It is important for companies to be aware of their responsibility to protect sensitive data and to take steps to prevent data leaks like this from occurring.
