Wireless attacks on aircraft instrument landing systems
Wireless attacks on aircraft instrument landing systems Sathaye et al., USENIX Security Symposium 2019
It’s been a while since we last looked at security attacks against connected real-world entities (e.g., industrial machinery, light-bulbs, and cars). Today’s paper is a good reminder of just how important it is becoming to consider cyber threat models in what are primary physical systems, especially if you happen to be flying on an aeroplane – which I am right now as I write this!
The first fully operational Instrument Landing System (ILS) for planes was deployed in 1932. But assumptions we’ve been making since then (and until the present day, it appears!) no longer hold:
Security was never considered by design as historically the ability to transmit and receive wireless signals required considerable resources and knowledge. However, the widespread availability of powerful and low-cost software-defined radio platforms has altered the threat landscape. In fact, today the majority of wireless systems employed in modern aviation have been shown to be vulnerable to some form of cyber-physical attacks.
Both sections 1 and 6 in the paper give some eye-opening details of known attacks against aviation systems, but to date no-one Continue reading
CrowdStrike-Ukraine Explained
Trump's conversation with the President of Ukraine mentions "CrowdStrike". I thought I'd explain this.What was said?
This is the text from the conversation covered in this
“I would like you to find out what happened with this whole situation with Ukraine, they say Crowdstrike... I guess you have one of your wealthy people... The server, they say Ukraine has it.”Personally, I occasionally interrupt myself while speaking, so I'm not sure I'd criticize Trump here for his incoherence. But at the same time, we aren't quite sure what was meant. It's only meaningful in the greater context. Trump has talked before about CrowdStrike's investigation being wrong, a rich Ukrainian owning CrowdStrike, and a "server". He's talked a lot about these topics before.
Who is CrowdStrike?
They are a cybersecurity firm that, among other things, investigates hacker attacks. If you've been hacked by a nation state, then CrowdStrike is the sort of firm you'd hire to come and investigate what happened, and help prevent it from happening again.
Why is CrowdStrike mentioned?
Because they were the lead investigators in the DNC hack who came to the conclusion that Russia was responsible. The pro-Trump crowd believes this conclusion is Continue reading

Deep Dive: How Do Banks Score on Privacy and Security?
In April 2019 the Internet Society’s Online Trust Alliance published its 10th annual Online Trust Audit & Honor Roll assessing the security and privacy of 1,200 top organizations. The Banking sector includes the top 100 banks in the U.S., based on assets according to the Federal Deposit Insurance Corporation (FDIC). Banks had a standout year, with a dramatic increase in scores across the board. Let’s take a closer look.
Overall, 73% of banks made the Honor Roll, putting the banking sector 4th behind the News and Media (78%), Consumer Services (85%), and the U.S. Federal Government (91%) sectors. In the previous Audit, only 27% made the grade. This large jump is due to improvements in all three scoring categories: email authentication, site security, and privacy.
Banks, like most sectors, came close to 100% adoption in the two main email security technologies studied in the Audit: SPF (93%) and DKIM (87%). In addition, banks saw a marked improvement in how many sites implemented both both technologies at 87% in 2018, up from 60% in 2017. This puts banks among the most improved sectors in this area.
DMARC builds on SPF and DKIM results, provides a means for Continue reading
HTTP/3: the past, the present, and the future
During last year’s Birthday Week we announced preliminary support for QUIC and HTTP/3 (or “HTTP over QUIC” as it was known back then), the new standard for the web, enabling faster, more reliable, and more secure connections to web endpoints like websites and APIs. We also let our customers join a waiting list to try QUIC and HTTP/3 as soon as they became available.
Since then, we’ve been working with industry peers through the Internet Engineering Task Force, including Google Chrome and Mozilla Firefox, to iterate on the HTTP/3 and QUIC standards documents. In parallel with the standards maturing, we’ve also worked on improving support on our network.
We are now happy to announce that QUIC and HTTP/3 support is available on the Cloudflare edge network. We’re excited to be joined in this announcement by Google Chrome and Mozilla Firefox, two of the leading browser vendors and partners in our effort to make the web faster and more reliable for all.
In the words of Ryan Hamilton, Staff Software Engineer at Google, “HTTP/3 should make the web better for everyone. The Chrome and Cloudflare teams have worked together closely to bring HTTP/3 and QUIC from nascent standards to widely Continue reading
50 ways to leak your data: an exploration of apps’ circumvention of the Android permissions system
50 ways to leak your data: an exploration of apps’ circumvention of the Android permissions system Reardon et al., USENIX Security Symposium 2019
The problem is all inside your app, she said to me / The answer is easy if you take it logically / I’d like to help data in its struggle to be free / There must be fifty ways to leak their data.
You just slip it out the back, Jack / Make a new plan, Stan / You don’t need to be coy, Roy / Just get the data free.
Hop it on the bus, Gus / You don’t need to discuss much / Just drop off the key, Lee / And get the data free…
— Lyrics adapted from “50 ways to leave your lover” by Paul Simon (fabulous song btw., you should definitely check it out if you don’t already know it!).
This paper is a study of Android apps in the wild that leak permission protected data (identifiers which can be used for tracking, and location information), where those apps should not have been able to see such data due to a lack of granted permissions. By detecting Continue reading

NSX-T Data Center and EUC Design Guide Release
When it comes to VMware NSX, support for VMware Horizon deployments have been a staple ask every release. NSX compliments Horizon deployments tremendously by:
- Helping to provide the networking for the Horizon components
- Identity and firewalling security for VDI and RDSH desktops
- Endpoint protection
- Load balancing
Earlier this year, NSX-T Data Center 2.4 was released which brought identity firewalling, endpoint protection, and other necessary features for customers to consume equivalent to NSX Data Center for vSphere. The release of NSX-T Data Center 2.5 takes those features and provides even further scale enhancements to support small, medium, and the largest Horizon deployments.
NSX-T Data Center and EUC Design Guide
The NSX-T and EUC Design Guide takes information provided in the VMware Horizon Reference Architecture and the VMware NSX-T Reference Design Guide, and brings the two platforms together into a single solution.
Use Cases and What’s Covered
Let’s take a look at what all is covered and the use cases that NSX-T Data Center has for Horizon deployments:
Horizon Pod Alignment
NSX-T Data Center 2.5 supports massive scale that can cover an entire Horizon Pod scale, and more in some cases. This design guide Continue reading

VMware NSX Achieves FIPS 140-2 Validation
Co-authored with Rajiv Prithvi, Product Manager Networking and Security Business Unit at VMware
During VMworld US 2019, we announced several new transformative capabilities in VMware NSX-T 2.5 release which is now shipping! The release strengthens the NSX platform’s intrinsic security, multi-cloud, container, and operational capabilities.
We also announced the successful FIPS 140-2 validation of NSX-T 2.5. FIPS compliance is mandatory for US federal agencies and has also been widely adopted in non-governmental sectors (e.g. financial services, utilities, healthcare). FIPS-140-2 establishes the integrity of cryptographic modules in use through validation testing done by NIST and CSE. With this validation, we further deliver on our confidentiality, integrity and availability objectives and provide our customers with a robust networking and security virtualization platform.
Compliance-Based Configuration with NSX-T 2.5
NSX-T 2.5 is configured to operate in FIPS mode by default. Any exceptions or deviations from established compliance norms are identified in a compliance report which can be used to review and configure your NSX-T Data Center environment to meet your IT policies and industry standards. Any exceptions to FIPS compliance including configuration errors can be retrieved from the compliance report using NSX Manager UI or APIs.
A sample FIPS Continue reading
Cleaning up bad bots (and the climate)
From the very beginning Cloudflare has been stopping malicious bots from scraping websites, or misusing APIs. Over time we’ve improved our bot detection methods and deployed large machine learning models that are able to distinguish real traffic (be it from humans or apps) from malicious bots. We’ve also built a large catalog of good bots to detect things like helpful indexing by search engines.
But it’s not enough. Malicious bots continue to be a problem on the Internet and we’ve decided to fight back. From today customers have the option of enabling “bot fight mode” in their Cloudflare Dashboard.
Once enabled, when we detect a bad bot, we will do three things: (1) we’re going to disincentivize the bot maker economically by tarpitting them, including requiring them to solve a computationally intensive challenge that will require more of their bot’s CPU; (2) for Bandwidth Alliance partners, we’re going to hand the IP of the bot to the partner and get the bot kicked offline; and (3) we’re going to plant trees to make up for the bot’s carbon cost.
Malicious bots harm legitimate web publishers and applications, hurt hosting providers by misusing resources, and they doubly hurt the planet Continue reading

New in Docker Hub: Personal Access Tokens
On the heels of our recent update on image tag details, the Docker Hub team is excited to share the availability of personal access tokens (PATs) as an alternative way to authenticate into Docker Hub.
Already available as part of Docker Trusted Registry, personal access tokens can now be used as a substitute for your password in Docker Hub, especially for integrating your Hub account with other tools. You’ll be able to leverage these tokens for authenticating your Hub account from the Docker CLI – either from Docker Desktop or Docker Engine:
docker login --username <username>
When you’re prompted for a password, enter your token instead.
The advantage of using tokens is the ability to create and manage multiple tokens at once so you can generate different tokens for each integration – and revoke them independently at any time.
Create and Manage Personal Access Tokens in Docker Hub
Personal access tokens are created and managed in your Account Settings.
From here, you can:
- Create new access tokens
- Modify existing tokens
- Delete access tokens
Note that the actual token is only shown once, at the time Continue reading
