Injection Flaws image
  • Jesper Ottosen's profile
Injections are about maliciously putting things where they’re not supposed to go. Originally, for input fields, like text boxes or forms, where someone could inject malicious code. One of the most famous examples is from the classic XKCD comic “Exploits of a Mom”, where a child is registered at school with a name that includes a bit of code, and it accidentally causes the school’s database to break. But it's not just about forms anymore. Prompt injections are similar in nature. Anywhere a user can put stuff is prone to injection flaws.Tip: Always validate and sanitize anything users can send.
Supply Chain Attack image
  • Jesper Ottosen's profile
Your web app will depend on libraries and third-party components outside your control. For example, Social media (SoMe) trackers and CSS or similar plugins. Over time, they might be insecure or outdated. This is known as a supply chain attack, when something you already trust becomes the way attackers get in. Tip: Keep a list of them and the last working version on your end. Examples: One famous example was log4j and another was SolarWinds.
