Digital thieves deploy poisoned emails in widespread attacks on crypto wallets, tricking users with fake security phrases sent from compromised accounts to steal funds directly from their wallets.
How Email Phishing Powers New Attacks on Crypto Wallets
The operation often starts with a breach. Attackers use phishing techniques – sending deceptive emails with malicious links or attachments – to steal login credentials for business tools. Specifically, they target accounts associated with customer relationship management (CRM) software and bulk email providers like Mailchimp, SendGrid, and Hubspot, according to analysis by security firm Silent Push.
Once inside these systems, the attackers may set up API keys. These keys grant them ongoing access, a persistent foothold even if the victim discovers the initial breach and changes their password. This access is crucial for the next stage: weaponizing the compromised account.
What Is the PoisonSeed Campaign?
Security researchers have named one prominent operation “PoisonSeed.” After gaining access, PoisonSeed operators export mailing lists stored within the compromised CRM or email platform.
They then use the platform’s own infrastructure to send out mass emails. Because these emails appear to come from a legitimate organization – the one whose account was compromised – recipients are far less likely to be suspicious.
This veneer of legitimacy is key to the scam’s effectiveness. The PoisonSeed campaign represents a dangerous evolution in email phishing crypto tactics.
Seed Phrases as a Trap: How It Works
The emails sent by PoisonSeed often impersonate known cryptocurrency companies, such as Coinbase. They might contain urgent warnings or instructions, telling the recipient they need to set up a new, secure crypto wallets immediately.
Crucially, the email provides a “seed phrase” – typically 12 or 24 words – needed to create or restore the wallet. This is the trap. The provided seed phrase was generated by the attackers, not by legitimate wallet software.
“Recipients of the bulk spam are targeted with a cryptocurrency seed phrase scam,” Silent Push stated in its report. If a user follows the instructions, creates a wallet using this phrase, and deposits funds, the attackers possess the master key. They can use the same seed phrase to access the wallet at any time and drain its contents.
Who’s Being Targeted—and Why It’s Not Just Crypto Pros
The reach of the PoisonSeed campaign extends beyond dedicated crypto enthusiasts. Targets include large businesses and individual users, many of whom may have only minimal interaction with cryptocurrencies.
The attackers cast a wide net, relying on the compromised email accounts to reach potential victims who might trust a message from a known company or service provider. This broad targeting underscores the pervasive nature of these attacks on crypto wallets.
While some tools used in PoisonSeed overlap with those employed by other known cybercrime groups, researchers assess it as potentially distinct, highlighting the continuous innovation by attackers in the crypto space.
Staying Safe: Best Practices Against Email-Based Scams on Crypto Wallets
Defense against these attacks requires caution and adherence to fundamental security practices:
- Be extremely skeptical of unsolicited emails demanding urgent action related to security or finances, especially those involving cryptocurrency.
- Never use a seed phrase provided to you in an email, message, or website. Legitimate seed phrases are generated only by your wallet software during setup and must be kept private and secure offline.
- Independently verify any requests or instructions by contacting the supposed sender through official channels, not by replying to the suspicious email.
- Use strong, unique passwords and enable multi-factor authentication (MFA) on all email, financial, and crypto-related accounts.
Understanding the mechanics of these scams is the first step toward avoiding them. Vigilance remains the most effective shield.
