Blockchain analytics firm Glassnode disclosed a security incident that may have exposed customer data, including email addresses. The company warned users to watch for phishing attempts.
What Glassnode said
Glassnode said it became aware of the incident recently and is investigating. The company did not specify how many customers were affected or when the breach occurred. It said the exposed data was limited to email addresses and did not include passwords, financial information, or other sensitive account details.
Email addresses at risk
While email addresses alone may seem low-risk, they can be used in targeted phishing campaigns. Attackers often use such information to craft convincing emails that appear to come from the company, tricking recipients into sharing login credentials or downloading malware. Glassnode's customer base includes cryptocurrency traders and investors, making them a potential target for sophisticated scams.
Phishing warning issued
Glassnode urged customers to be cautious of unsolicited emails requesting personal information or urging them to click on links. The company said it would never ask for passwords or private keys via email. It recommended that users enable two-factor authentication and use unique, strong passwords for their accounts.
Investigation underway
Glassnode said it has engaged external security experts to assist with the investigation. The company is working to identify the source of the breach and implement additional security measures. It did not provide a timeline for when the investigation might conclude or whether law enforcement has been notified.
Customers who receive suspicious emails claiming to be from Glassnode should report them to the company's support team. The incident serves as a reminder that even limited data exposure can have consequences in the crypto space, where phishing remains a persistent threat.
