XSS and Login Phishing in DeepSeek AI

A recent post on Coffin by a user highlighted security vulnerabilities in DeepSeek AI, specifically concerning cross-site scripting (XSS) and login phishing.

While the XSS attack was deemed ineffective due to the use of a CDN domain that prevents cookie access, the login phishing vulnerability remains a concern.

This allows attackers to potentially harvest user credentials.

The user also noted that DeepSeek has restricted the sharing of private chats, likely as a response to ongoing cyberattacks.

DeepSeek’s Broader Security Challenges

DeepSeek AI, a Chinese startup, has been under scrutiny for its security practices since releasing its cost-efficient AI model, R1.

Despite its innovative approach, the model has faced criticism for numerous vulnerabilities:

1. Database Exposure: Researchers from Wiz discovered an unsecured database infrastructure that exposed sensitive data, including chat histories and API keys. This misconfiguration allowed unauthorized access and even administrative control over the database.
2. Jailbreaking Susceptibility: DeepSeek R1 has been found highly vulnerable to jailbreaking techniques. These attacks bypass safety mechanisms, enabling the model to generate harmful or malicious content. Cisco researchers reported a 100% success rate in jailbreaking attempts against R1, highlighting its lack of robust guardrails compared to competitors like OpenAI’s GPT models.
3. Phishing Risks: Cybercriminals have exploited AI vulnerabilities to craft sophisticated phishing campaigns. Jailbroken models can generate highly personalized messages, increasing the effectiveness of such attacks.

Implications of Login Phishing

The persistence of login phishing as an effective attack vector poses significant risks:

• Credential Theft: Attackers can steal user credentials, potentially compromising personal data and sensitive information.
• Broader Exploitation: Once credentials are obtained, attackers could gain unauthorized access to private chats or other services linked to DeepSeek’s platform.
• Reputational Damage: Such vulnerabilities undermine trust in DeepSeek’s security measures, potentially deterring users and businesses from adopting its services.

Mitigation Measures

To address these issues, DeepSeek must adopt comprehensive security protocols:

• Database Security Enhancements: Implementing authentication mechanisms and encryption for sensitive data.
• Strengthening Model Guardrails: Incorporating advanced safety measures to resist jailbreaking attempts.
• User Awareness: Educating users about phishing risks and promoting best practices for account security.

While DeepSeek AI has made significant strides in making AI accessible at lower costs, its security lapses highlight the need for robust safeguards.

Addressing vulnerabilities like login phishing is essential not only for protecting users but also for ensuring the long-term viability of its platform in an increasingly competitive AI landscape.
