Opinionated, engineering-focused writing about application security, vulnerability research, and the tools used to separate risk from noise.
OWASP Orizon started in 2006 with ASTs, program models, call graphs and data flow. Dawnscanner took a more pragmatic path. Twenty years later, DRSource is bringing me back to the same question: how much...
AI will automate a significant part of Product Security work, but it will not eliminate the need for security engineers. The real shift is from scanner-driven vulnerability management toward architecture, exploitability, mitigation design, secure...
NGINX Rift and PoolSlip expose dangerous memory corruption flaws inside one of the Internet’s most trusted reverse proxies, turning rewrite rules into a potential remote code execution surface. From long-lived heap bugs to new...
Signal Engine 0.3.0 transforms raw security findings into structured, actionable insight. With clustering, deduplication, and risk-based hotspots, noise gives way to clarity. Less data to sift through, more signal to act on.
Soak is a zero-dependency Docker image that aggregates a curated set of open-source security scanners into a single, reproducible execution environment.
Turning security tool outputs into actionable insights is one of the biggest challenges for developers and security engineers. In this post, I’m sharing a minimal viable product (MVP) that takes Semgrep scan outputs and...
In the previous post, we saw how many security tools can “lie”: they don’t tell the full story, generate noise, and often leave teams with a false sense of security. But what happens after...
We live in a world where developers and security teams are drowning in alerts. Every scanner, every automated tool, every “security dashboard” promises to tell you what matters—but in reality, most of it is...
During my OSCE exam preparation I had to deal with shellcode writing experience where very few allower characters were available.
In order to monitor dawnscanner security scaner usage, I introduced in upcoming version 2.0.0, a telemetry system.
A couple of days ago, I was working on my exploit-writing routine as preparation for my upcoming OSCE examination.
During my OSCE journey I came across an interesting technique to jump backwards into the very beginning of the buffer injected on the vulnerable process.
The egghunting is a technique used in exploit writing to deal with evil shellcode to be placed in a memory location different from the one we are redirected via EIP overwrite or SEH hijack...
Vulnserver is a Win32 application built to simulate a TCP/IP server listening on port 9999 and accepting commands from unauthenticated clients.
It was last year when I received the email saying I passed the Penetration testing with Kali Linux course and eventually I became an OSCP guy.
Sometime I need to quick nmap the network just right cable plug. Since I’m lazy I created a simple bash script to calculate the network address in CIDR notation, starting from ifconfig output.
Last summer, as I told on Codice Insicuro, my Italian blog about cybersecurity and related, I took the x86 Assembly Language and Shellcoding on Linux course and related certification.
During those days I’m spending in the mountains with my family, I’m studying module 3 and 4 about backdooring executable with custom payloads and avoiding anti-viruses based on signature detection.
In 2018 I refreshed my offensive security skills, attending the “Penetration test with Kali” course with the OSCP certification.
It was 2014 when I wrote the latest post on armoredcode.com. It was about Ruby patching Wednesday and tons of stuff changed in my life.
Past weeks were busy for Ruby on Rails core team and appsec people looking at the framework’s security. Yesterday, core rails member Aaron Patterson announced three Ruby on Rails security issues affecting latest versions...
Today I was working over a new tabular output for Codesake::Dawn and I faced a problem. Vulnerabilities have a very long description that breaks all formatting resulting in something unreadable.
It was a busy month. Web sites out there are still attacked by villains and the first Codesake::Dawn major release was out this week. That’s because I didn’t post anything since last December.
Wow, last week it was very busy in the ruby security annonuncement discussion group. A bunch of six new vulnerabilities were announced and, most of them, are cross site scripting issues. This is bad...
A couple of days ago, on Italian Ruby mailing list, Paolo Montrasio reported two security issues occured in the ruby world.
UPDATE For a mistake this post appeared today on armoredcode.com without the text. Reason is that I created a placeholder to remember me to work on this.

Nothing but solving a real world problem can help boosting a piece of software to evolve.
In a previous post I talked about Rapid7 Nexpose) vulnerability assessment tool and how you can write some ruby code to search a server by IP address.
Next time you point your browser to a /login url wait a minute before submitting your credentials. There is a complex system you’re going to use when you submit that form and it must...
In 2006 I started an ambitious project, an opensource SAST engine built in Java I called Owasp Orizon.
It was a yesterday’s news that anonymous and other cracker’s crews attacked and defaced large number of corporate websites.
Make a web application penetration test is becoming tricky due modern browsers native anti-xss filtering facilities (they only work for reflected cross site scripting).

Life is too short to change framework or to learn a new programming language only because there is no a shortcut to print out if a string starts with a given pattern.
