Hey there,

I hope you’ve been doing well!

Screenwriting Follow-up

Last week I shared some potential pitches for what I believe could be the plot for “Through My Window,” an upcoming “steamy romance” movie on Netflix, whose tagline is: “It all started with the Wi-Fi password…”

The pitches were artisanally crafted for believability, technical accuracy, educational content (why not teach computer security in a narrative form?), and fiery romance. After all, a long-haired man on a horse is an icon for many a romance novel, and many hackers have long hair. Coincidence? I think not.

Anywho, I offered my screenwriting services to help on the film, and I received this response from Patrick Thomas:

Netflix Rejection

Your move Apple TV, Disney+, Amazon Prime, etc.

In good faith, I’d like to offer a line my bud Adam Berman came up with:

“I’ll have whatever Wi-Fi she’s having.”

📢 Make software security a priority in 2022

With the increasing rise of security breaches that exploit software vulnerabilities, 2022 is the year to invest in releasing quality software - that is also secure - faster, regardless of the language:framework it is built on. To do that, you need security aware and enabled developers that code securely as applications are being created. Let Secure Code Warrior show you how >>

AppSec

OWASP WrongSecrets
12 challenges consisting of examples of how not to use secrets, by Xebia’s Jeroen Willemsen, ENACT-IT’s Ben de Haan, et al. Find the different secrets with various tools and techniques, and learn if you’re doing secret management correctly.

Improving Web Vulnerability Management through Automation
Lyft’s Nicolas Flacco describes how they automated the process of scanning various endpoints via headless Burp, exporting the results, and auto-creating Jira tickets for identified issues. There are some implementation challenges here, for example, detecting duplicate issues, items marked as “won’t fix”, reoccuring issues, etc.

Lyft Burp Scanning

Eliminating Authorization Vulnerabilities with Dacquiri
As mentioned last week, Nathanial Lattimer’s Rust library Dacquiri “turns authorization vulnerabilities into compile-time errors.” This post walks through an example of using Dacquiri to help secure a hypothetical send money feature for a bank. Using secure-by-default frameworks and leveraging type systems for security guarantees is 🔥

By gating privileged actions in your application behind Dacquiri’s entitlement system, it will ensure that every single codepath that interacts with the protected function has performed the required authorization checks ahead of time.

Mobile Security

optiv/InsecureShop
An intentionally vulnerable Android application built in Kotlin, by Optiv’s Gaurang Bhatnagar and Matt Eidelberg. Over 19 vulnerabilities, most based on real vulnerabilities found in an actual pen test.

Web Security

hahwul/authz0
An automated authorization test tool by Hahwul. URLs and roles are managed as YAML-based templates, you can leverage ZAP and Burp history, and more.

blst-security/cherrybomb
A CLI tool that helps you avoid undefined user behavior by validating your API specifications. It takes in a Swagger file, runs a series of checks on it to make sure everything is on par with the OAS, and outputs a detailed table with any alerts found. Cherrybomb can also take in your logs and check them for business logic flaws.

Security Program Building

Secrets of Successful Security Programs - Part 2
The second part of Phil Venables’s guide (my notes on part 1 here) covers overall program management and practices that are necessary for ongoing and effective risk mitigation. Topics include: establishing sources of funding, building and maintaining an effective team, establishing a strong security baseline with The Essential 20, and more.

This post neatly summarizes and weaves through, in a very satisfying way, 10+ other posts Phil has written that go into each aspect in more detail. Another must read.

CISO’s Guide to a Modern AppSec Program
James Chiappetta on cybersecurity’s influence on organizational culture (be an enabler, not a blocker), a getting started AppSec program checklist, building out AppSec focus areas, and various useful pro-tips and takeaways.

The High-quality Security Newsletters Rami McCarthy reads and why
Great thread by Rami McCarthy, which introduced me to a few I’ve now joined.

Cloud Security

ramimac/aws-customer-security-incidents
A repo by Rami McCarthy aiming to index all publicly disclosed AWS customer security incidents with a known root cause, so they can be learned from.

Stratus Red Team
Very cool new tool by Christophe Tafani-Dereeper (GitHub), an open-source adversary emulation tool for the cloud. A standalone Golang binary that comes with a catalog of cloud-native attack techniques that you can easily detonate to test your threat detection. Datadog blog post announcement, Christophe’s behind the scenes making of post that includes details about the process of creating it, design decisions, and more.

WeAreCloudar/cfn-drift-remediation
Tool by Cloudar that uses the Cloud Control API to remediate drift that was detected on a CloudFormation stack. Reads the existing drift of a stack, iterate through the drifted resources and construct a patch document to change the actual (detected) property values to the expected (stack) values.

Container Security

appvia/cosign-keyless-admission-webhook
Kubernetes admission webhook that uses cosign verify to check the subject and issuer of the image matches what you expect, by Appvia.

I met Ahsan Mir, one of the founders of Rapticore, when he was the CISO at Autodesk. Super nice and sharp guy. I like how they’re focusing on observability, and breaking down what can be siloed views in many companies.

Network Security

Introducing Scanning Made Easy
The NCSC will be releasing a collection of Nmap scripts to help identify systems with certain high risk vulnerabilities. The first is for Exim message transfer agent (MTA) RCEs, by NCC Group’s Ollie Whitehouse.

Reverse Engineering

Debugging a Java application with decompiled source code
dozer describes how to decompile Java targets and connect them to an IntelliJ IDEA project for live debugging, which is very useful to tracking values passed to interesting or dangerous functions at runtime (e.g. Runtime.exec()).

Frida HandBook
Virus Total’s @entdark_ describes how to use the binary instrumentation tool Frida, covering Frida internals, how (not) to approach common tasks, and advanced topics.

Politics / Privacy

North Korea Hacked Him. So He Took Down Its Internet
A year after the North Korean campaign to target Western security researchers, one targeted researcher, P4x, was annoyed at the lack of U.S. government response. So he found a number of North Korean systems running software with unpatched vulnerabilities (e.g. nginx, Apache), and has been using those flaws to DoS their websites, routers, etc.
