Skincare giant Clarins allegedly hit in data breach with 600,000 customers exposed — what you need to know
Hackers claim to have the personal details of thousands of customers

A prolific ransomware group has claimed to have exposed the data of over 600,000 customers of luxury French skincare company, the Clarins Group. According to Cybernews, whose research team examined the dark web post by the hacking group, the sample data contains customer details including names, birth dates, addresses, phone numbers and email addresses from the company’s customers across the U.S., France and Canada.
Though the hackers from the notorious Everest group claim to have “a variety of personal documents and information," so far the data only shows info that would likely be accessed from online stores across multiple regions. The data is the kind of information that customers often provide when signing up to purchase products online, or when signing up for loyalty programs. The hacking group did share more information from two additional databases but those details have information that would appear to come from online shops such as purchase histories of skincare and makeup products.
While it may not appear to be particularly damaging information on the surface, this supposedly exposed data could be repurposed to carry out other malicious actions such as phishing attacks, used to spread malware or used to obtain further user data that could then be used for identity theft. The Cybernews team that investigated the posted data stated that “The usual threats in these cases include phishing attacks and spam…Personal identifiers enable other impersonation crimes such as tax return fraud or general identity theft.”
The Everest ransomware group is believed to have been around for at least four years and first came to notoriety back in October 2022 attack against AT&T. There has been no claim for ransom for the Claris Groups data so far, that has been reported. According to one dark web monitoring tool, Everest has hit over a hundred organizations in the past 12 months.
Clarins, a luxury skincare company and popular in Europe and American markets, is headquartered in Paris with an annual revenue of roughly $2.35 billion, making it an attractive target. It employs around 8,000 people which also means there are a number of methods by which threat actors could apply potential social engineering attacks.
How to stay safe after a data breach

Doing so before falling victim to a data breach is ideal as you'll be able to take full advantage of the identity theft insurance offered by one of these services to recover any lost funds.
In this case, it's important to be on high alert for phishing attempts – specifically look out for any emails that sound urgent and want you to “act now” to fix an issue, to provide additional personal or financial details, or need you to correct an account problem. It's also important to stay vigilant against social engineering attacks and to monitor your accounts for suspicious activity. The best way to stay safe against phishing is to avoid clicking on any links, QR codes or attachments in emails or messages from unknown senders.
