Linux Snap Store Attack: Critical Warning as Hackers Hijack Trusted Publishers to Steal Crypto Seed Phrases

In a chilling cybersecurity development for 2025, blockchain security firm SlowMist has exposed a sophisticated Linux Snap Store attack targeting cryptocurrency seed phrases through hijacked publisher accounts, revealing critical vulnerabilities in software distribution channels that millions of Linux users trust daily. This supply-chain attack represents a significant escalation in cryptocurrency theft tactics, moving beyond traditional phishing to exploit the very infrastructure users rely on for security.

Linux Snap Store Attack Exploits Expired Domain Vulnerabilities

Blockchain security company SlowMist has identified a dangerous new attack vector specifically targeting Linux users through the official Snap Store. According to their chief information security officer, known as 23pds, attackers are systematically monitoring Snap Store developer accounts linked to domains that have expired but were previously associated with legitimate publishers. Once attackers re-register these expired domains, they gain access to domain-linked email addresses and can reset Snap Store account credentials, effectively hijacking established publisher accounts with existing download histories and active user bases.

The compromised applications reportedly impersonate popular cryptocurrency wallets including Exodus, Ledger Live, and Trust Wallet, using interfaces that closely resemble legitimate software. When users install or update these malicious applications through what appears to be official channels, the software prompts them to enter wallet recovery phrases, allowing attackers to exfiltrate credentials and drain funds without users realizing they have been compromised. This method represents a particularly insidious form of attack because it exploits established trust relationships rather than relying on user error.

Technical Breakdown of the Attack Methodology

The attack follows a carefully orchestrated sequence that security experts find particularly concerning. First, attackers identify Snap Store publisher accounts linked to domains approaching expiration. They monitor these domains continuously, waiting for the registration to lapse. Upon expiration, attackers immediately re-register the domain, gaining control over associated email addresses. Using these email addresses, they reset Snap Store publisher account credentials, taking control of established accounts with existing user bases and download histories.

From this position of trust, attackers can push malicious code through routine software updates rather than requiring fresh installations. This approach significantly increases the attack’s effectiveness because existing users automatically receive updates through their normal update channels. The malicious updates maintain the appearance of legitimacy while introducing code designed to harvest cryptocurrency seed phrases and private keys.

Confirmed Compromises and Immediate Threats

SlowMist has confirmed that two publisher domains have already been compromised using this attack vector: “storewise[.]tech” and “vagueentertainment[.]com.” Applications tied to these accounts were reportedly modified to impersonate well-known cryptocurrency wallets, creating a dangerous situation for Linux users who rely on the Snap Store for secure software distribution. The Snap Store serves as Linux’s equivalent of Apple’s App Store on macOS and the Microsoft Store on Windows, making this compromise particularly significant for the open-source community.

Security analysts note that this attack methodology represents a sophisticated understanding of both cryptocurrency infrastructure and Linux software distribution. By targeting the update mechanism rather than initial installations, attackers ensure their malicious code reaches users who have already vetted and trusted the software. This approach bypasses many traditional security checks that focus on new installations rather than updates to existing trusted applications.

Comparative Analysis: Traditional vs. Supply-Chain Attacks

The Growing Threat of Supply-Chain Attacks in Cryptocurrency

This Snap Store attack vector aligns with a broader, alarming shift in cryptocurrency-related threats throughout 2025. Attackers are increasingly targeting infrastructure and distribution channels rather than smart contract code or individual users. According to data from blockchain security firm CertiK shared with Crypto News Insights in December, total cryptocurrency hack losses reached $3.3 billion in 2025, despite a sharp decline in the number of individual incidents. This paradox reveals a critical trend: losses are becoming concentrated in fewer but more damaging supply-chain attacks.

CertiK’s analysis shows that supply-chain attacks accounted for $1.45 billion in losses across just two major incidents in 2025. This concentration of losses in sophisticated infrastructure attacks suggests that as protocol-level security improves through better auditing and formal verification methods, attackers are shifting toward higher-impact tactics that exploit trust relationships, software update mechanisms, and third-party infrastructure. The trend represents a fundamental evolution in cryptocurrency security threats that requires corresponding evolution in defense strategies.

Key Characteristics of Modern Supply-Chain Attacks

• Trust Exploitation: Attackers leverage established trust rather than creating new relationships
• Update Mechanism Abuse: Malicious code spreads through routine updates rather than initial installations
• Infrastructure Targeting: Focus shifts from end-users to distribution channels and development tools
• Extended Dwell Time: Attacks remain undetected longer due to legitimate appearance
• Cross-Platform Potential: Techniques developed on one platform often transfer to others

Linux Security Implications and User Protection Strategies

The Linux community faces particular challenges from this type of attack due to the decentralized nature of Linux distribution and software management. While the Snap Store provides centralized software distribution similar to commercial app stores, many Linux users also obtain software through package managers, direct downloads, and community repositories. This diversity of software sources creates both challenges and opportunities for security.

Security experts recommend several immediate protective measures for Linux users concerned about this threat. First, users should verify the authenticity of software publishers through multiple channels before installing or updating cryptocurrency wallets. Second, implementing additional verification for software updates, including checksum verification and publisher signature validation, can provide additional security layers. Third, maintaining offline backups of seed phrases and using hardware wallets for significant cryptocurrency holdings remains essential despite these new attack vectors.

Industry Response and Mitigation Efforts

The cybersecurity community has responded to this threat with both technical solutions and educational initiatives. Snap Store maintainers are implementing enhanced domain verification processes and more rigorous account recovery procedures. Security researchers are developing tools to monitor for domain expiration patterns that might indicate preparation for similar attacks. Meanwhile, cryptocurrency wallet developers are improving their update notification systems to provide clearer verification methods for legitimate updates.

Industry collaboration has proven particularly valuable in addressing these sophisticated threats. Information sharing between security firms, software distributors, and cryptocurrency projects enables faster detection and mitigation of similar attacks across different platforms. This collaborative approach represents a maturing cybersecurity ecosystem better equipped to handle evolving threats.

Historical Context and Evolution of Cryptocurrency Attacks

The Snap Store attack represents the latest evolution in a continuous arms race between cryptocurrency security professionals and attackers. Early cryptocurrency attacks primarily targeted individual users through phishing and social engineering. As user awareness improved, attackers shifted to targeting exchange platforms and trading systems. The subsequent improvement in exchange security led to a focus on smart contract vulnerabilities and protocol-level exploits.

Now, with improved auditing practices and formal verification methods reducing smart contract vulnerabilities, attackers have moved further up the technology stack to target development tools, distribution channels, and infrastructure components. This progression follows a predictable pattern observed in traditional cybersecurity: as defenders strengthen one layer, attackers probe adjacent layers for weaknesses. The current focus on supply-chain attacks suggests that cryptocurrency infrastructure has reached a level of maturity where it presents attractive targets for sophisticated attackers.
