Enterprise Dataflow

We can help you design, develop, and launch your cloud-based platform. Our team has deployed enterprise applications on all the major cloud providers.

Kubernetes is a container technology that allows you to package up your application and move it effortlessly between on-premise infrastructure and cloud platforms. Kubernetes provides autoscaling, automated failover and recovery, availability, and transparency for your critical business services. Syscall 7 can help you port your existing applications to Kubernetes and guide you through the deployment of your production system.

Our team of enterprise web developers can help you build a slick user-interface for your custom application or help you architect a backend application that is scalable and load-balanced for enterprise deployment.

Reverse Engineering

Software Reverse Engineering is sometimes the only method for addressing certain kinds of challenges. Here are some of the reasons why you might need to hire a competent firm to provide reverse engineering services for your business:

  • Interoperability – If your company is developing novel ways to interact with existing technology, then you might find yourself needing to identify the binary interfaces of closed-source, proprietary systems. For example, your product might want to speak a certain undocumented protocol in order to control a hardware device for which there is no published documentation.
  • Reclaim Ownership of Data – Sometimes closed-source technology holds a customer’s data hostage so a customer cannot switch providers. In this case, you might need to reverse engineer that particular product in order to regain ownership of your own data.
  • Combat Malware – If your company has been the victim of a cyber attack, understanding the internal workings of the malware with which you were attacked is vital to a successful mitigation campaign.
  • Recover Source Code – Sometimes companies lose their own source code and only have access to the binary executables. Reverse engineering technologies are so good these days that oftentimes we are able to reconstruct something very close to the original source code from just the raw binary executable.

Our team of reverse engineers are skilled in analyzing binary images targeting a wide range of computing platforms.

Static Analysis

Analysis Sans Execution

Disassembling the Binary

Reconstruct the Logic

Dynamic Analysis

Analysis Through Execution

Executing the Code

Monitor at Runtime

Binary Dissection

Dissecting Files and Protocols

Files and Protocols

Model the Data

With Static Analysis, we will use cutting edge tools like Ghidra, IDA Pro, and BinaryNinja to analyze the binary. Control flow analysis will tell us which parts of the code are executed under which conditions. Data flow analysis will show us how local and global data structures are used throughout the program and help us map out how information flows in the program.

Dynamic Analysis allows us to monitor and “hook” the running code to more intricately understand the inner workings of the application under investigation. We use binary instrumentation technologies such as Intel PIN, DynamoRio, and Frida to gather runtime data as the program executes. We may use emulation tools like Qemu or Unicorn Engine to further analyze the program.

Most applications rely on either local files or networking protocols for storing critical data or communicating with the outside world. We will make use of valuable tools like Wireshark and Scapy to observe and model network communications. We may also hook up bus monitoring tools or logic analyzers to the hardware to observe digital communications between components.

Performance Analysis

If your application performance is not optimal, your users will suffer and your competitors will seek to take advantage of that. Optimal performance means different things in different application contexts. Reliability is always an important factor, and so is responsiveness. We can generate metrics tailored to your specific application to help you find ways to improve the reliability and responsiveness of your software.

Source Code Review

Enumerate Components and Dependencies

We start by reviewing documentation, identify critical areas, map out flow of data, and enumerate external dependencies.

Scan for Vulnerabilities

Next we will use a collection of open source and proprietary scripts and utilities to scan your software for known vulnerabilities. We also look for known vulnerabilities in all external library dependencies.

Review Critical Areas

For the most critical sections of code, we will manually analyze all the source to identify potential logic flaws and insecure operations.

Deliver Report

Finally, we document all our findings and suggested remediations in a detailed report.

Security Audits

Penetration Testing

In a Penetration Test, we will explore all the attack surfaces a bad actor might use to compromise your system.

System Hardening

Sometimes “good enough” is not sufficient. Our experts can recommend techniques that you can use to harden your system for real world use.
