I hope you’re doing well! It’s important to set aside some time, especially in these unusual times, to relax, do something you enjoy, and maybe cut loose and go wild.
Like me, for example- last weekend I had ~600 lbs of Ikea furniture delivered, so I spent about one and a half days assembling it.
I know not everyone is comfortable throwing caution to the wind and raging hard like that, but what can I say, that’s just the kinda person I am.
Sidenote: If you’re thinking about buying one of Ikea’s customizable PAX storage units, check out the PAX planner. It’s Flash (ugh), but pretty useful for testing the visual layout of various components.

Cyber June’Gle Virtual Summit
I gave my “Opinionated Guide to Scaling Your Company’s Security” talk at this great event, which was organized by the DEF CON Red Team Village. The variety of talks was really cool to see, I appreciated that. Youtube Playlist of the talks.
Software Security Gurus Webcast Episode #7: Clint Gibler
I chatted with my bud Matias Madou, CTO and co-founder of Secure Code Warrior, about static analysis, threat modeling, and writing summaries for an entire conference.
📢 Datadog Security Monitoring
Security threats in cloud-native environments move fast, which means that security teams need to have the same visibility into their infrastructure, network, and applications as developers and operations. With Datadog Security Monitoring, engineering teams can easily detect malicious activity in real-time before it affects their customers. Use OOTB detection rules and detailed observability data in one, unified platform to investigate security attacks. See it in action by signing up for a live security demo

Playing Around With The Fuchsia Operating System
Detailed post by Quarkslab, discussing the Zircon micro kernel and attacking Fuchsia: the USB and Bluetooth stack, a hypervisor
vmcall bug, and kernel mishandling of
A few days of vulnerability research allowed us to conclude that the common programming bugs found in other OSes can also be found in Fuchsia. However, while these bugs can often be considered as vulnerabilities in other OSes, they turn out to be uninteresting on Fuchsia, because their impact is, for the most part, mitigated by Fuchsia’s security properties.
We note however that these security properties do not - and in fact, cannot - hold in the lowest layers of the kernel related to virtualization, exception handling and scheduling, and that any bug here remains exploitable just like on any other OS.
Fuchsia has the potential to significantly increase the difficulty for attackers to compromise devices.
System hardening in Android 11
Post by Google describing a number of hardening steps, including automatic memory initialization in both Android 11’s userspace (stack variables) and the Linux kernel (stack and heap initialization), Scudo is now Android’s default native memory allocator (hardened to help detect and mitigate memory corruption bugs in the heap), and more.

Crooks abuse Google Analytics to conceal theft of payment card data
To conceal their data exfiltration, some attackers are sending data they’ve skimmed to an account they control on google-analytics.com, which tends to be whitelisted by site owners.
Cached and Confused: Web Cache Deception in the Wild
Usenix 2020 paper, overview article by Portswigger’s Ben Dickson.
We present the first large-scale study that quantifies the prevalence of WCD in 340 high-profile sites among the Alexa Top 5K. Our analysis reveals WCD vulnerabilities that leak private user data as well as secret authentication and authorization tokens that can be leveraged by an attacker to mount damaging web application attacks. Furthermore, we explore WCD in a scientific framework as an instance of the path confusion class of attacks, and demonstrate that variations on the path confusion technique used make it possible to exploit sites that are otherwise not impacted by the original attack. Our findings show that many popular sites remain vulnerable two years after the public disclosure of WCD.

Threat Alert: DzMLT has Hidden Cryptominers in Container Images
Aqua Security found 23 Docker Hub container images that included crypto mining code, collectively downloaded over 330,000 times. To avoid detection by static security tools, many of them downloaded malicious elements hosted on GitHub at runtime.
Container Vulnerability Scanning Fun
NCC Group’s Rory McCune ran 3 open source vuln scanning tools (Anchore Engine, Clair, trivy) on 4 base images. Key takeaways:
- Even in base images, different scanners product very different results.
- The scanning engines support different sets of base images, so keep that in mind when you’re deciding which one to use.
- Even in a fully updated base image, there can still be outstanding CVEs, depending on the update cycle of both Docker Hub and the underlying distribution.
