Why Does Wallet Need Audit?

Millions of dollars have been lost in several widely known breaches of cryptocurrency wallets. The Mt. Gox hack in 2014 led to the loss of about 850,000 bitcoins (worth about $450 million at the time), as well as the DAO hack in 2016, which resulted in the loss of about $60 million worth of ether, are two of the most noteworthy hacks. In recent times, Hackers have stolen large amounts of cryptocurrency in some instances, such as the $3.8 billion stolen in 2022.

A crypto wallet product's security is critical to ensuring users' funds' safety. Suppose a wallet product is not properly secured. In that case, it can be vulnerable to a range of attacks, including theft of private keys, unauthorized access to the wallet, and tampering with transactions.

A crypto wallet product security audit is essential in ensuring the safety and security of cryptocurrency assets. As the use of cryptocurrencies has become more widespread, the number of wallet products has increased, making it challenging for users to choose a wallet that is both easy to use and secure. This is where a security audit comes in - it can thoroughly assess a wallet product's security posture, identify vulnerabilities, and provide recommendations for remediation.

Audit Process

Things We Cover in the Audit Process :

Secure Key Management
Authentication and Authorization
Secure Communication Protocols
Third-party Component Security
Key Derivation
Access Control
Secure Storage
Mobile Wallet/Extension Mobile Security

We ensure your smart contract goes through all the stages, from manual code review to automated testing, before generating the Initial Audit Report. Once your team updates the code, we thoroughly scrutinise the smart contract to provide you with the Final Audit Report. Let’s dive deep into it and explore more.

Step 1 - Specification Gathering / Prepare For a Security Audit

Gather information about the wallet product, such as documentation and source code, to understand its architecture and functionality.
The scope of the wallet pentest security audit should be clearly defined in advance. This should include the wallet product under test, any associated mobile applications or web interfaces, and any relevant third-party components.
This is the most crucial stage because details are key for a successful smart contract Security audit. Here is how you can prepare for it:

Code quality • Remove dead code and comments. • Consistent coding style.

Use comments to document complex parts of the code and ensure these are consistent with thecoded.e

Step 2 - Vulnerability Assessment Test

The vulnerability assessment phase involves testing the wallet product for vulnerabilities. This may include:

Testing the authentication and authorization mechanisms to identify any weaknesses or vulnerabilities.
Testing the input validation mechanisms to identify potential injection attacks, such as SQL injection or cross-site scripting (XSS) attacks.
Testing the key management process to identify any weaknesses or vulnerabilities in the key derivation process or backup key management.
Testing the cryptography mechanisms to identify any weaknesses or vulnerabilities in the encryption algorithms or key sizes.
Testing the network security measures, such as firewalls or intrusion detection systems (IDSs), to identify potential weaknesses or vulnerabilities.
Testing the mobile application or web interfaces to identify potential vulnerabilities or weaknesses in the user interface.

Step 3 - Exploitation Phase

The exploitation phase involves attempting to exploit any identified vulnerabilities. This may include:

Attempting to bypass authentication or authorization mechanisms.
Attempting to inject malicious code or commands into the wallet product.
Attempting to steal sensitive data, such as private keys or transaction data.
Attempting to launch denial-of-service (DoS) attacks against the wallet product or associated services.

Step 4 - Testing Over Various Attacks

Improper Platform Usage
Insecure Data Storage
Insecure Communication
Insecure Authentication
Insufficient Cryptography
Insecure Authorization
Client Code Quality
Code Tampering
Reverse Engineering
Extraneous Functionality
Indirect Object Reference
Functionality Abuse
Business Logic
Wallet Seed Phrase Protection
Previous attack exploits
Transfer of tokens from and in the application
Rate Limit Issues and Brute-forcing

Step 5 - Testing with Automated Tools

Burp Suite
Frida
Nmap
Metasploit
Horusec
Postman
Netcat
Nessus and many more.
