Threat to Ledger Users: What to Do After a Data Breach

The recent Ledger data breach clearly demonstrated that security isn't limited to blockchain and crypto wallets. The exposure of personal information—including contact information and home addresses—has unleashed a new wave of sophisticated cyberattacks targeting Ledger customers specifically. GetBlock AML Research explains what to do after a data breach to protect your assets.

Ledger Data Breach: What Happened

Ledger recently experienced another data breach. In an official statement, the company reported that a security incident occurred at one of its payment partners, Global-e.

As a result of unauthorized access, attackers were able to view information about users who made purchases on Ledger.com through Global-e. The compromised data included:

• First and last name;
• Mailing address;
• Email address;
• Phone number;
• Some order details.

Important: Recovery phrases and private keys were not compromised. Furthermore, the breach affected more than just Ledger customers. The attacker gained access to Global-e's cloud system, which stored order data for customers of several major brands. Bank card details and payment information were not compromised.

Understanding Modern Fraud Schemes

Before protecting your crypto wallet, it's important to understand the main types of scams today:

Classic Phishing

Phishing attacks have become much more convincing. Fraudsters use real leaked data—your name, order history—to make emails and messages appear to be genuine requests from Ledger support. This makes it much more difficult to distinguish a scam from a legitimate message.

AI-Based Scams

Attackers use artificial intelligence to impersonate the voices or faces of famous people, such as company executives or support staff. They may call you, send you a voice message, or even video chat you via messaging app, claiming to have an urgent security issue.

Quishing (QR Code Phishing)

This type of scam is rapidly gaining popularity. A person receives an email or email with a QR code asking them to "verify" their device. After scanning, they are directed to a fake website asking them to enter a 24-word secret phrase.

Fake SMS and Calls

Since phone numbers are also leaked, scammers can send SMS messages that appear to be part of a legitimate conversation, such as a delivery message. They often use pressure: "Your account will be blocked in 2 hours. Confirm your details immediately."

Fake Extensions and Apps

Fake wallet software updates are distributed through advertisements or unofficial stores. While they look identical to the original, they contain malicious code that steals funds when the device is connected.

Physical Attacks ("Wrench Attacks")

Knowing the wallet owner's exact address, criminals can attempt to access funds through physical pressure or threats. In this case, a simple data leak turns into a real threat to personal security.

How to recognize a trap

Even the most sophisticated scams have common signs. Chief among them is an artificially created sense of urgency and fear. They try to scare you and force you to act immediately, without giving you time to calmly verify the information.

Strict security rule: Ledger will never, under any circumstances, ask for your 24-word passphrase. Not by email, by phone, or through websites or apps. This passphrase is the complete key to your funds, and any request to provide it is a theft attempt.

It's also important to be careful with links. Scammers often use website addresses that look almost identical to the real ones, but differ by a single letter or symbol. It's always best to enter the website address manually rather than click links in messages.

Be especially careful with regular mail. Ledger very rarely sends emails or devices without the user's request. Any unexpected package with a "device replacement" is highly likely a fake.

Strengthening Security

After a data breach, protection requires a comprehensive approach—both to your digital identity and to your device settings. First and foremost, it's important to minimize the risks associated with the disclosure of personal data. To do this, it's helpful to use separate or hidden email addresses for cryptocurrency-related services. This reduces the likelihood that a future breach will directly link to your primary email address.

Using SMS for two-factor authentication is no longer considered secure. SIM card swapping is a common practice. The minimum level of protection is switching to authenticator apps that generate codes directly on the device.

For maximum protection, you can use hardware security keys, which require the physical presence of the device when logging in to your account. This approach virtually eliminates the possibility of remote hacking, even if scammers know your login and password.

The last line of defense

The final level of protection is your personal discipline when confirming transactions. Carefully check all transaction details on the device screen before confirming. If a transaction appears incomplete or conceals the recipient's address and amount, it should be considered dangerous and cancelled immediately.
