Secure Coding Labs

Practice real-world secure coding scenarios through hands-on challenges and labs.

Regular-expression Denial Of Service or ReDos happens when a regular expression engine requires an exponential amount of steps to recognise...

Horizontal Privilege Escalation occurs when a user is able to access another user’s resources at the same privilege level. This...

Horizontal Privilege Escalation happen when a user can access another users resources. Usually this vulnerability is exploited by tampering with...

Prototype Pollution occurs when untrusted input is used to add or modify attributes of an object prototype. An adversary can...

MD5 and SHA1 are weak hashing algorithms and open to collision attacks. They are not suitable for cryptographic signature. Remediation...

NIST has defined a number of criteria for making strong password. These criteria become more complex over the time and...

In cryptography, salt refers to some random addition of data to an input before hashing. Without unique hashing salts adversaries...

Typosquatting happens when a user mistypes an input (e.g. URL, email, dependency package, etc.) and does not visually verify if...

Unicode normalisers are used to transform Unicode strings into a consistent form so that equivalent characters can be reliably compared....
