SGL: Mapping the open-source genome for fun and profit

By Mark Curphey August 30, 2017

For a long-time we have known that the current state-of-the-art of vulnerability research in open-source code does not scale. That current state-of-art involves individual security researchers looking at specific bits of code and then reporting potential issues found to a central vulnerability database in the form of textual descriptions. If accepted (after some basic validation) the report is re... READ MORE

Open-source Packages with Malicious Intent

By Vanessa Henderson August 3, 2017

Why re-invent the wheel? This famous saying is what I think of when thinking about third-party code. Package managers such as npm, RubyGems, and Maven make it so easy to share code that has been written between people that developers use it for tasks as small as checking if a number is positive. This is absolutely great but how many of us stop to think about what exactly is going on behind-the-... READ MORE

This is the fourth entry in a blog series on using Java cryptography securely. The first entry provided an overview covering architectural details, using stronger algorithms and debugging tips. The second one covered Cryptographically Secure Pseudo-Random Number Generators. The third entry taught you how to securely configure basic encryption/decryption primitives. This... READ MORE

Anatomy of a Cross-Site Scripting Flaw in the Telerik Reporting Module

Telerik Reporting Cross-Site Scripting Vulnerability

One of the interesting aspects of working as a Veracode Application Security Consultant is seeing the wide range of code across many business sectors. On an average day, I could look at some COBOL code twice my age in the morning, and by lunch I’m exploring a large .NET MVC app, before transitioning to review a self-deploying microservices package comprised of Java, node.js, and a little PHP for...

Skip to the tl;dr Cryptography is the backbone of today's information systems. Its applications are all around us: secure email communications, storage of our login credentials, digital cash and mobile payments, to name just a few. Cryptography is one of the most complicated topics in information security, but the good news is we already have well-defined algorithms, implementations and protocols... READ MORE

Abusing npm libraries for data exfiltration

By Asankhaya Sharma November 10, 2016

Package and dependency managers like npm allow command execution as part of the build process. Command execution provides an easy and convenient mechanism for developers to script tasks during the build. For instance, npm allows developers to use pre-install and post-install hooks to execute tasks. A pre-install hook can be used to compile some dependent native library before starting the build....

A deep dive into analyzing dynamic languages

By Darius Foo November 7, 2016

Analyzing programs written in dynamic languages presents some unique challenges. Here's a bit of a deep dive into how we do it. First, what exactly is a dynamic language? For the purposes of this article, we will define a dynamic language as one where types are checked for safety only at runtime. Languages like Ruby, Python, and JavaScript follow this model, in contrast with static languages like... READ MORE

A look at Vulnerabilities and Dependencies by Language

By Brian Wallace October 24, 2016

As a Data Scientist at SourceClear I get to analyze lots of interesting vulnerability data as well as anonymized project data. New customers often ask us what "normal" looks like when it comes to vulnerabilities in their projects, so I thought I'd take a look and share a few insights. How many projects have vulnerabilities, and how many do they usually have? I looked at projects analyzed with... READ MORE
