Why Invest in Application Security? (2015)
Released: June 21, 2015
Running a business requires being cost-conscious and minimizing unnecessary spending. The benefits of ensuring in the security of your application are invisible to most companies, so often times they neglect to invest in secure software development as a cost-saving measure. What these companies don't realize is the potential cost (both financial and to brand reputation) a preventable data compromise can incur.
The average data breach costs millions of dollars in damage.
Investing more time and personnel to develop secure software is, for most companies, worth it to minimize this unnecessary risk to their bottom line.

OWASP Cheat Sheet Series is a GitHub repository of markdown security cheat sheets, one file per application-security topic, maintained by the OWASP Foundation. The official reading surface is cheatsheetseries.owasp.org; the repo itself is the source and the place contributions land as pull requests.
Awesome Hacking is a GitHub-hosted index of other security awesome-lists, maintained by Hack-with-Github, with two tables of external links split between primary awesome-list repositories and standalone reference tools. It doesn't teach anything itself - every row is a one-line pointer to someone else's list, spanning Android security to prompt injection against AI systems, released under CC0-1.0.
Payloads All The Things is an open-source GitHub repository maintained by swisskyrepo that collects payloads and bypass techniques for web application security testing. The README describes it as organized by vulnerability class, with each section containing a README.md write-up, example payloads, and often files for Burp Intruder.
x64dbg is an open-source debugger for Windows built to inspect executables you don't have source code for, aimed squarely at reverse engineering and malware analysis. It ships as separate 32-bit and 64-bit builds, bundles disassembly, assembly patching, and import reconstruction into one download, and can be extended through a documented plugin system.
