I hope you’ve been doing well!
Our lives are like brilliant strands of thread in the rich tapestry of life.
We weave in and out of each other’s lives, building connections and sections of the big picture.
Sometimes there are seemingly insignificant strands that somehow wind their way into our lives.
For me, one strand began years ago, in a discount bargain bin in a Walmart in Cincinnati, Ohio.
There, my sister found the following
#PeakBayArea game, which she bought for
me for Christmas, and then promptly forgot about it until we rediscovered the game
this year, years later, while cleaning out a closet.
The game is this: you draw cards for a company name, a target user demographic, and an industry you’re disrupting, and then you make up a product and pitch your start-up to the “VC” player.
As you’d expect, the cards are both ridiculous and something you might overhear discussed earnestly at a Blue Bottle Coffee in SF.
I played it with my family and with some work colleagues- everyone loved it. The latter was admittedly a bit dangerous, as there was a non-zero chance of causing the world to explode due to too much irony, with real-life Silicon Valley start-up founders playing… Silicon Valley founders pitching start-ups to VCs.
Life imitates art imitates… card games. -Sam Altman, a16z

Android security checklist: WebView
Several ways to exploit WebViews, ways to increase the impact of the attack if an attacker is able to load an arbitrary URL, and recommendations for preventing these vulnerabilities or reducing their impact, by Oversecured.
Getting Started with iOS Penetration Testing (Part 1)
iOS architecture overview, some sample vulnerable apps, testing methodology, setting up your proxy, jailbreaking, bypassing jailbreak detection and SSL pinning, checking for sensitive data exposure, by YesWeHack
AWS Security Reference Architecture
60pg PDF by AWS Professional services containing a holistic set of guidelines for deploying the full complement of AWS security services in a multi-account environment. GitHub repo with example solutions.
By RunX: “Infrastructure-as-code where you work with high-level constructs instead of getting lost in low level cloud configuration.” Uses Terraform under the hood so you’re not locked in. Blog post.
In Opta, modules are a first class citizen. There are modules for all the common resources that one might need — like EKS, RDS, DynamoDB, GKE, Cloud SQL, etc and even third party services like Datadog. All these modules are designed by Infrastructure experts — so they follow all the best security practices and are production grade. Plus they are designed to work really well with each other.
By Apiiro’s Moshe Zioni: A modular and extensible framework to detect and prevent dependency confusion leakage and potential attacks. Facilitates an approach for ensuring secure application releases that can be evaluated against different sources (e.g., GitHub Packages, JFrog Artifactory) and many package management schemes (e.g., npm, maven).
How to analyze malicious documents – Case study of an attack targeting Ukrainian Organizations
Nice walkthrough of analyzing potentially malicious files by Cyber Geeks, with examples of some useful tools by Philippe Lagadec et al.
- oleid can be used to analyze OLE files such as MS Office documents (e.g. Word, Excel) to detect potentially malicious characteristics like VBA macros, embedded Flash objects, and fragmentation.
- olevba can detect VBA Macros and extract their source code in clear text, detect security-related patterns such as auto-executable macros, suspicious VBA keywords used by malware, anti-sandboxing and anti-virtualization techniques, and potential IOCs (IP addresses, URLs, executable filenames, etc). It also detects and decodes several common obfuscation methods.
- ViperMonkey is a VBA Emulation
engine that can be used to analyze and deobfuscate malicious VBA macros.
Launching a community-driven insider threat knowledge base
MITRE Engenuity’s Jon Baker et al, in conjunction with several industry partners, have released the Insider Threat TTP Knowledge Base, a collection of tactics, techniques, and procedures (TTPs) used by known insiders in IT environment. This initial publication is based on analysis of insider threat case data contributed by participants and 54 identified techniques that have been used by insiders. See this PDF for more info and the TTPs in detail. GitHub repo.
MITRE Engenuity’s ATT&CK Flow helps executives, SOC managers, and defenders easily understand how attackers compose ATT&CK techniques into attacks by developing a representation of attack flows, modeling attack flows for a small corpus of incidents, and creating visualization tools to display attack flows.
At a high level, ATT&CK Flow is a machine-readable representation of a sequence of actions and assets along with knowledge properties about those actions and assets. Home page.
Politics / Privacy
On this page we provide a list of charts, data and resources that you may find useful to understand the context of the ongoing war in Ukraine.
We do not publish any data on the ongoing war in Ukraine, but instead we provide longer-term and global context on military resources, conflicts, energy production and trade, political regimes and other relevant topics.
