Naxsi - An Open-Source, High Performance, Depression Rules Maintenance Waf For Nginx

Image
NAXSI agency Nginx Anti XSS & SQL Injection . Technically, it is a 3rd political party nginx module, available every bit a parcel for many UNIX-like platforms. This module, past times default, reads a pocket-sized subset of simple (and readable) rules containing 99% of known patterns involved inwards website vulnerabilities. For example, < , | or drop are non supposed to last operate of a URI. Being rattling simple, those patterns may gibe legitimate queries, it is the Naxsi's administrator duty to add together specific rules that volition whitelist legitimate behaviours. The administrator tin either add together whitelists manually past times analyzing nginx's fault log, or (recommended) get-go the projection alongside an intensive auto-learning stage that volition automatically generate whitelisting rules regarding a website's behaviour. In short, Naxsi behaves similar a DROP-by-default firewall, the solely chore is to add together required ACCEPT r...

Flerken - Obfuscated Ascendency Detection Tool

Image
Command business obfuscation has been proved to endure a non-negligible cistron inwards fileless malware or malicious actors that are "living off the land". To bypass signature-based detection, dedicated obfuscation techniques are shown to endure used past times red-team penetrations as well as fifty-fifty APT activities. Meanwhile, numerous obfuscators (namely tools perform syntax transformation) are opened upwards sourced, hence making obfuscating given commands increasingly effortless. However, the position out of suitable defenses remains to endure few. For Linux command line obfuscation, nosotros tin barely divulge whatever detection tools. Concerning defenses against Windows ascendance obfuscation, existing schemes plough out to either lack of toolization, or alone partially resolve the entire problem, sometimes fifty-fifty inaccurately. To amend facilitate obfuscation detection, we accept proposed Flerken, a toolized platform that tin endure used to hono...
