Project description

Job requirements

• Language: English
• Working experience: binary code and malware analysis, IDA, security vulnerabilities, understand data structures and algorithms involving dozens of functions all from nothing but binary
• Education: EU citizens/residence holders – any; others have to have a University degree (starting from Bachelor) so we can sponsor the work permit think-cell distinguishes itself from other Microsoft Office add-ins by having an intuitive user interface, smart algorithms that automate many tasks and, not least, a deep integration into its Office host application.
To achieve this deep integration, we use the public APIs offered by Office and Windows whenever we can, but unfortunately, they do not let us do everything we want to do. So we add our own customization hooks into the Office and Windows binaries. When think-cell loads, it finds the code locations and installs its hooks. Instead of using fixed addresses, we find code locations using machine code patterns to be robust against minor changes. If an update to Office or Windows still breaks some of the patterns, think-cell will automatically download and install any available version with updated patterns. Finding ways to achieve a desired customization is a truly zen-like activity. It requires deep analytical skills, the ability to juggle vast amounts of information in the head and quickly separate promising from less promising approaches.
