Thick Client Penetration Testing

BreachLock thick client application penetration testing assesses applications that operate on users devices and communicate with a server or backend system. During thick client penetration testing, we identify security weaknesses not only in the applications themselves but also their interactions with networks and other aspects of their security.

Thick Client Applications

BreachLock thick client penetration testing primarily involves assessing the security of the thick client software itself. This may include:

Authentication and Authorization Testing

Evaluating the strength of authentication mechanisms and assessing whether the application enforces proper access controls.

Data Encryption

Analyzing how sensitive data is encrypted and protected within the application.

Insecure Configuration

Identifying and addressing security misconfigurations in the application, such as default settings or unnecessary privileges.

Client-Side Exploitation

Attempting to exploit client-side vulnerabilities that could be leveraged by an attacker to compromise the application or the user's device.

Network Assessment

BreachLock thick client penetration testing also includes assessing the network communication between the thick client application and the back-end server. This may involve:

Traffic Analysis

Examining network traffic to understand how data is transmitted between the client and server, looking for vulnerabilities like unencrypted data or weak encryption protocols.

Man-In-The-Middle (MITM) Attacks

Evaluating the susceptibility of the communication channel to MITM attacks that could intercept or manipulate data.

Firewall and Network Configuration

Assessing the security controls and configurations in place on the network infrastructure to protect thick client communications.

Server-Side Assessment

While the primary focus is on the client-side, BreachLock thick client penetration testing may also involve limited evaluation of server-side components to ensure they are not vulnerable to attacks originating from the client. This can include assessing server-side APIs or services that interact with the thick client.

End-User Behavior and Social Engineering

Since thick clients run on end-user devices, our pentesting may also involve evaluating user behavior and susceptibility to social engineering attacks that could compromise the thick client or associated credentials.

Secure Data Handling

BreachLock pentesters will ensure that the thick client application securely handles sensitive data, such as authentication tokens or cached data, on the user's device.

Offline Analysis

BreachLock can also assess how the thick client application behaves when it operates in an offline or disconnected state and whether any vulnerabilities arise in such scenarios should your organization wish to test offline.
