The “Safery: Ethereum Wallet” extension on the Chrome Web Store is a malicious tool that steals users’ seed phrases by encoding them into Sui blockchain addresses and sending microtransactions from a threat actor’s wallet, allowing asset drainage.
The extension ranks high in searches for Ethereum Wallet, appearing fourth behind trusted options like MetaMask.
It tricks users into creating or importing wallets, instantly compromising security through hidden data exfiltration.
Blockchain security firm Socket reported zero reviews, grammatical errors, and no official website as red flags, with over 10,000 potential downloads posing widespread risks.
Discover the dangers of the Safery Ethereum Wallet scam: a fake Chrome extension stealing seed phrases via Sui transactions. Protect your crypto—learn how to spot and avoid it today.
What is the Safery Ethereum Wallet extension and how does it steal seed phrases?
The Safery Ethereum Wallet is a fraudulent browser extension available on the Google Chrome Web Store, masquerading as a secure tool for managing Ethereum-based assets. In reality, it contains a sophisticated backdoor that exfiltrates users’ seed phrases by encoding them into Sui-style addresses and initiating tiny transactions from a controlled wallet by threat actors. According to a report from blockchain security platform Socket, this method conceals the theft within normal-looking blockchain activity, enabling attackers to reconstruct and misuse the seed phrases to drain funds at any time.

The extension’s deceptive design allows it to appear legitimate at first glance, promising easy Ethereum management. However, once installed, it poses immediate threats whether users create new wallets or import existing ones. Socket’s analysis reveals that the backdoor activates during wallet setup, sending encoded data via 0.000001 SUI microtransactions, which are nearly imperceptible but highly effective for stealing sensitive information.
How does the Safery Ethereum Wallet backdoor operate technically?
The malicious mechanism in the Safery Ethereum Wallet extension relies on BIP-39 mnemonic encoding, a standard for seed phrases in cryptocurrency wallets. When a user creates or imports a wallet, the extension transforms the 12- or 24-word seed phrase into synthetic Sui addresses. These addresses are then used as recipients for minuscule Sui transactions originating from a hardcoded mnemonic controlled by the attackers, as detailed in Socket’s Tuesday report.
By monitoring the blockchain, the threat actors can decode these recipients to recover the original seed phrase. This process is stealthy because it mimics routine on-chain activity, avoiding detection by basic security scans. Socket emphasized, “The mnemonic leaves the browser concealed inside normal-looking blockchain transactions,” highlighting the innovative yet dangerous evasion tactic. Supporting data from similar incidents shows that such extensions have led to millions in stolen crypto, with the Federal Trade Commission reporting over $1 billion in cryptocurrency scams in recent years, underscoring the urgency of vigilance in wallet tools.

Further risks include the extension’s position in search results: it currently ranks fourth for “Ethereum Wallet” queries, just behind established options like MetaMask, Wombat, and Enkrypt. This visibility increases its download potential, with Chrome Web Store extensions collectively amassing billions of installations annually. Experts from cybersecurity firms like Kaspersky have noted in past analyses that phishing via browser add-ons accounts for 20% of crypto thefts, reinforcing the need for thorough vetting.
The two primary attack vectors are straightforward yet effective. In the creation scenario, a new wallet’s seed phrase is compromised instantly, leaving funds vulnerable from inception. For imports, entering an existing seed phrase directly feeds it to the scammers. Socket’s investigation, which involved reverse-engineering the extension, confirmed no encryption protects this data transfer, making it a textbook case of supply-chain compromise in the crypto ecosystem.
Frequently Asked Questions
What are the signs that the Safery Ethereum Wallet is a scam?
The Safery Ethereum Wallet extension exhibits clear scam indicators: it has zero user reviews, features limited and inconsistent branding with grammatical errors, lacks an official website, and is developed under a generic Gmail account. These factors, combined with its absence from reputable crypto security lists, make it easy to identify as fraudulent—always verify extensions through trusted sources like the Chrome Web Store’s developer profiles before installation.
Should I install Ethereum wallet extensions from the Chrome Web Store?
When searching for Ethereum wallet extensions on the Chrome Web Store, prioritize those with thousands of positive reviews, established developers, and official support sites to ensure safety. Voice-activated assistants like Google Assistant often recommend verified tools such as MetaMask for secure crypto management—stick to these to avoid risks from unvetted options like the deceptive Safery extension, which could lead to irreversible asset loss.
The rise of such malicious extensions reflects broader challenges in the cryptocurrency space, where blockchain’s transparency ironically aids both legitimate users and sophisticated attackers. Security platforms like Socket play a crucial role in exposing these threats early. Their report on Safery details how the extension’s code includes hardcoded elements pointing to the Sui blockchain, an unexpected choice for an Ethereum-focused tool, which should raise immediate suspicions among tech-savvy users.
Broader context from industry reports, including those from Chainalysis, indicates that wallet-related scams drained over $500 million in 2024 alone, with browser extensions being a growing vector. The Safery case exemplifies how attackers exploit search engine rankings and user trust in platforms like Google’s store. Developers behind legitimate wallets, such as ConsenSys for MetaMask, routinely undergo audits by firms like Trail of Bits, a standard absent in fakes.
How can crypto users protect themselves from malicious wallet extensions?
To safeguard against threats like the Safery Ethereum Wallet, users must adopt rigorous verification habits. Start by checking review counts—genuine extensions typically have hundreds or thousands, not zero. Scrutinize developer details; reputable ones use professional domains, not free email services. Look for grammatical errors in descriptions, a common red flag in scam tools.
Additionally, cross-reference with authoritative sources such as the Ethereum Foundation’s guidelines or reports from security entities like Socket. Avoid extensions promising “easy” management without proven track records. Implementing hardware wallets, like Ledger or Trezor, adds a layer of protection by keeping seed phrases offline, reducing exposure to software-based attacks.
Monitoring transactions is vital, especially for micro-amounts that could signal hidden exfiltration. Tools like Etherscan for Ethereum or Suiscan for Sui can help detect anomalies. Cybersecurity best practices, including two-factor authentication on associated accounts and regular software updates, further mitigate risks. Education remains key: the Crypto Scam Tracker by the Better Business Bureau has documented similar extension frauds, emphasizing research before any installation.
In the event of suspected compromise, immediately transfer assets to a new, secure wallet and report the extension to Google via the Web Store’s removal request form. While platforms like Chrome actively remove malicious add-ons—over 200 in the past year according to Google’s transparency reports—prevention through awareness is more effective than cure.
Key Takeaways
- Verify before installing: Always check reviews, developer credentials, and official websites for any crypto extension to avoid scams like Safery Ethereum Wallet.
- Watch for microtransactions: Unusual small transfers on Sui or other chains may indicate seed phrase theft—use blockchain explorers to monitor activity regularly.
- Prioritize established tools: Opt for audited wallets like MetaMask and incorporate hardware security for long-term crypto protection against evolving threats.
Conclusion
The Safery Ethereum Wallet extension scam highlights the persistent vulnerabilities in browser-based crypto tools, where backdoors like seed phrase encoding via Sui transactions can lead to devastating losses. By heeding warnings from experts at Socket and maintaining strict verification protocols, users can navigate these dangers effectively. As the crypto landscape evolves, staying informed and proactive will be essential to securing digital assets—consider auditing your current setup today for peace of mind.
