Hey there,

I hope you’ve been doing well!

The Economy 😅

Oof, a number of companies are continuing to lay off significant numbers of people.

My thoughts are with everyone who has been affected. Keep your head up, you’re going to land on your feet somewhere awesome, I believe in you.

I’m going to update my open jobs page in the near future, apologies to everyone who sent me new jobs for being a bit slow.

But it’s not just employees who are getting affected, even VCs are:

Fortunately, VCs all have unique insights and value adds, and don’t just happen to have a money gun that they can swing around and be “successful” when they’re right 10% of the time.

📢 Moving from Spreadsheets to Modern GRC Platforms: What to Know

Using spreadsheets to manage your IT risk or compliance programs? From clunky and disorganized workflows to manual evidence collection and control monitoring, it's time to stop spending hours of time on menial tasks instead of strategic initiatives.

Web Security

Caido
A lightweight web security auditing toolkit. Like ZAP or Burp, but written in Rust.

vmware/burp-rest-api
A REST/JSON API for Burp Suite.

CiscoCXSecurity/bbqsql
A blind SQL Injection exploitation tool.

cybervelia/graphicator
By Cybervelia’s Theodoros Danos: A GraphQL “scraper” / extractor. The tool iterates over the introspection document returned by the targeted GraphQL endpoint, and then re-structures the schema in an internal form so it can re-create the supported queries.

AppSec

FIDO2, New Hires & Lost Keys
Palantir’s Chris Dunn and Kimmy Richardson describe how Palantir handles the “chicken and egg” new FIDO2 user problem (Azure TAP codes) and when users lose keys.

Enforcing Device AuthN & Compliance at Pinterest
Pinterest’s Armen Tashjian describes how they’ve enforced the use of managed and compliant devices in their Okta authentication flow, using a passwordless implementation, so that access to their tools always requires a healthy Pinterest device.

Pinterest Okta Device Compliance

Threat and Vulnerability Hunting with Application Server Error Logs
Wix’s Moti Harmats shares a clever approach: monitor specific application runtime exceptions to find exploitable vulnerabilities. For example, “SQL syntax error” means an improperly structured SQL query, which could be caused by an unparameterized SQL query + runtime data affecting it.

Wix applied this approach to several vulnerability classes and found it to be high signal: 100% true positives for XXE and SSTI, and 26% for SQL injection. They set up an out-of-band monitoring solution to prevent runtime overhead (like if you had a RASP).

Security Drone: Scaling Continuous Security at Revolut
Revolut’s Krzysztof Pranczk describes how Revolut’s continuous scanning approach evolved to be more effective. They scan every PR, put Security Drone in a Kubernetes cluster to scan code independently of CI/CD pipelines, and use Semgrep for SAST, Snyk for software composition analysis, and Checkov for IaC.

Initially, we used 19 SAST and 63 IaC rules. Only high and critical SCA issues were directly reported to our developers.

We lowered the false positive rate by carefully choosing the SAST solution and continual tuning of rules. We were able to achieve ~3.8% FP rate!

Cloud Security

awslabs/iam-roles-anywhere-session
This package provides an easy way to create a refreshable boto3 Session with AWS Roles Anywhere.

Lambda risks
Rami McCarthy’s notes on the risks and threat model of AWS Lambda, focusing on attack vectors, and not CI/CD concerns like the risks of Lambda Layers.

AWS SCPs - Governance: Setting security controls at the organizational level
2nd Sight Lab’s Teri Radichel walks through how using SCPs can help you follow the Don’t Repeat Yourself (DRY) principle, and example useful policies like limiting the principals who can deploy/modify SCPs, preventing removal of an account from an organization, and other useful hardenings.

GoogleCloudPlatform/security-response-automation
Take automated actions on your GCP Security Command Center findings, like:

  • Automatically create disk snapshots to enable forensic investigations.
  • Revoke IAM grants that violate your desired policy.
  • Notify other systems such as PagerDuty, Slack or email.
Gcp Security Response Automation Architecture

Container Security

google/containerdbg
An all-in-one CLI tool to help debug Kubernetes containers with common issues that arise when moving to containers as part of legacy application modernization.

Kubernetes Security-Guard
A tool focused on assisting Knative users in securing their deployed services, for example, by monitoring and potentially blocking requests and/or responses to Knative services based on a per-service security configuration.

Guard In Knative

Blue Team

Swipe right on our new credit card tokens!
Thinkst Canary has released a new canary token type: credit cards. They’ll create a valid credit card (number, expiration, and CVC) for you, and you’ll get notified if it ever gets used.

Politics / Privacy

TikTok confirms that its own employees can decide what goes viral

That the company promotes certain videos, sometimes to enhance relationships with creators and businesses, is no longer just an open secret.

Good thing this Chinese-owned company would never promote or demote videos to advance China’s political agenda, as Chinese companies are totally independent from the Chinese government, and there’d never be US user data accessed from China, and they’d never use the platform to spy on Forbes journalists.

Machine Learning

Google plans to demo AI chatbot search as it panics about ChatGPT
Article title is a bit alarmist, but Google founders Larry Page and Sergey Brin have gotten a bit more involved, and Google plans to launch over 20 AI products this year, including a demo of its own search chatbot.

In the past, Google has said it’s avoided launching certain AI products because of the potential “reputational damage.”

An interesting example of the relative advantages/disadvantages of being a start-up (e.g. OpenAI) and being OK with being wrong.

ChatGPT in an iOS Shortcut — Worlds Smartest HomeKit Voice Assistant
How to create an iOS shortcut that uses GPT-3 to interpret your voice command and then send intelligent commands to your smart home devices. Nice example of a detailed prompt that returns output as structured JSON. It can do smart things like, turn on the lights when you say:

Just noticed that I’m recording this video in the dark in the office. Can you do something about that?

CNET’s Article-Writing AI Is Already Publishing Very Dumb Errors
CNET had been quietly publishing articles generated by an unspecified “AI engine.” CNET never publicly announced the program, and that the disclosure that the posts were bot-written was hidden away behind a human-sounding byline — “CNET Money Staff” — made it feel as though the outlet was trying to camouflage the provocative initiative from scrutiny.

It’s worth pointing out, as Platformer’s Casey Newton did this week, that CNET’s AI-generated finance articles arguably only exist in the first place because they’re trying to manipulate Google’s algorithm for profit. Countless better explanations of compound interest already exist; CNET’s strategy is simply to publish large volumes of cheaply produced text, carefully optimized to float to the top of search results, in a bid to capture the monetizable eyeballs of the financially curious.

“Over time, we should expect more consumer websites to feature this kind of ‘gray’ material: good-enough AI writing, lightly reviewed (but not always) by human editors, will take over as much of digital publishing as readers will tolerate,” Newton wrote. “The quiet spread of AI kudzu vines across CNET is a grim development for journalism, as more of the work once reserved for entry-level writers building their resumes is swiftly automated away.

brycedrennan/imaginAIry
Tell AI how to update photos via a text description. Make a “photo of a fruit bowl” and “portrait photo of a freckled woman,” now “replace the fruit with strawberries” and “make her a cyborg.”
