Cryptocurrency Tax Platform Security Alert: Waltio Leaks Information of 50,000 Users Due to Hacker Attack

The tax reporting platform Waltio, designed specifically for cryptocurrency asset holders, recently became a target for hackers. It is reported that a hacking group called “Shiny Hunters” claimed to have illegally obtained personal information of approximately 50,000 customers of the platform and demanded a large ransom from the company. The incident has been reported to the French police, sparking renewed industry concern over data security on crypto platforms.

Hacker Group’s Ransom Tactics Escalate

According to PANews, the attacked Waltio platform is dedicated to providing portfolio tracking and tax calculation services for cryptocurrency investors. The hackers claim to have successfully stolen sensitive information such as users’ email addresses and account balances during 2024. Such data is highly valuable to hacker groups—emails can be used for further phishing attacks, while account balance information could lead to targeted scams.

This incident reflects a worrying trend: hackers are no longer solely targeting exchanges or wallet applications but are beginning to focus on foundational tools and service platforms. Tax reporting tools, which hold comprehensive user asset information, have become new targets for attack.

Impact of Data Breach on Crypto Users

The leak of 50,000 users’ information is significant. For affected users, it not only poses a risk of personal privacy exposure but also makes them potential targets for subsequent scams or extortion. The “account balance information” obtained by hackers is especially dangerous—meaning they know the scale of the target user’s assets and can carry out precise scam activities.

Such events also serve as a wake-up call for the entire crypto industry. Even platforms offering legitimate services can become weapons in the hands of hackers, threatening the funds and privacy of countless innocent users.

How Crypto Users Can Protect Themselves

In the face of increasingly active hacker threats, cryptocurrency asset holders should take proactive defensive measures. First, users who have registered on Waltio or similar platforms should immediately change their account passwords and enable two-factor authentication. Second, be cautious of emails from suspicious senders, especially those claiming to involve account verification or asset confirmation—these are common phishing tactics used by hackers.

Additionally, users are advised to prioritize platforms with comprehensive security certifications and regular security audits when choosing tax reporting tools. Regularly checking your crypto assets and promptly detecting abnormal transactions are also crucial defensive steps. Under hacker threats, security awareness and preventive measures are often more important than remedial actions after an incident.
