  • Google Makes an Open-Source Tool for Linux to Avoid USB Keystroke Attacks [Ed: "A day after researchers declared Linux having more vulnerabilities than Windows" is false. Several lies there. Not researchers and no such thing declared, either.]

    A day after researchers declared Linux having more vulnerabilities than Windows, Google now makes a free tool to be used by Linux systems to avoid potential USB keystroke attacks. The software would be running background to monitor any suspicious activities from a plugged USB, and notify a user about potential attacks. This was published by Google in its GitHub for Linux PCs.

  • 83% of medical imaging devices running on outdated operating systems, report finds

    An overwhelming majority of medical imaging devices are running on old operating systems with little-to-no ability to receive crucial software updates, according to a new report. It’s a small piece of the larger security problem plaguing internet-connected devices.

    That’s according to new research from enterprise security firm Palo Alto Networks which analyzed more than 1.2 million devices stationed across thousands of healthcare institutions in the U.S. The 83% of imaging devices running on outdated platforms represents a large uptick from the 56% figure reported in 2018.

    Imaging devices run on a wide variety of operating systems, such as Linux and Unix, but much of the jump seen over the past few years is attributable to the Windows 7 operating system reaching its end of life, the report authors noted. And these vulnerable in radiology equipment may open the door for criminals to attack the wider healthcare field.

    Josh Bressers: The Security Scanner Problem

    Are you running a security scanner? It seems like everyone is doing it, maybe it’s time to get with it. It’s looking like automated security scanning is the next stage in the long winding history of the security industry. If you’ve never run one of these scanners that’s OK. I’m going to explain what they are, how they work, how we’re not using them correctly, and most importantly, what you can do about it. If you are running a scanner I’m either going to tell you why you’re doing it wrong, or why you’re doing it REALLY wrong. If you’re a vendor who builds a security scanner I assure you I understand there is a high probability I am indeed an idiot and don’t know what I’m talking about. I’m sure everything will be fine.

    Automated scanning IS changing the world, but right now it’s not changing it for the better, it’s currently the security industry version of lead paint. The technology is still REALLY new, so it’s important we have proper expectations and work together to make things better. One of the challenges with new technology is understanding what you have now, and more importantly understanding what you need next. Like any tool, if you use it wrong it can make things worse than doing nothing at all. Let’s talk about how to make things better.

    If you’ve never seen the sort of report an automated scanner generates you should probably consider yourself lucky. The best way to describe these reports is if you had a 10 page report that wasn’t very good, then you made 100 copies of every page, shuffled them around a bit and stapled it all together. There are some useful findings in the report, but they’re really hard to find. Expecting anyone to parse a 1000 page report for one or two findings has a terrible return on investment. It’s even less helpful if you send the report to someone else with unrealistic demands, such as requesting they fix all of the findings. By Friday. If you didn’t read the report, why should they?

  • Part 1: Is your security scanner running? You better go catch it!

    This post is the first part in a series on automated security scanners. I explain some of the ideas and goals in the intro post, rather than rehashing that post as filler, just go read it, rehashing content isn’t exciting.

    There are different kinds of security scanners, but the problem with all of them is basically the same. The results returned by the scanners are not good in the same way catching poison ivy is not good. The more you have, the worse it is. The most important thing to understand, and the whole reason I’m writing this series, is that scanners will get better in the future. How they get better will be driven by all of us. If we do nothing, they will get better in a way that might not make our lives easier. If we can understand the current shortcomings of these systems, we can better work with the vendors to improve them in ways that will benefit everyone.

  • Part 2: Scanning the code

    If you just showed up here, go back and start at the intro post, you’ll want the missing context before reading this article.

    The first type of scanner we’re going to cover are source code scanners. It seems fitting to start at the bottom with the code that drives everything. Every software project has source code. It doesn’t matter what language you use. Some is compiled, some interpreted, it’s all still source code. The idea behind a source code scanner is to review the code a human wrote and find potential security problems with it. This sounds easy enough in theory, but it’s extremely difficult in practice.

    Strongly typed languages like C, C++, and Java lend themselves to code scanning. An oversimplified explanation would be a strongly typed language is one where a named variable has to be a certain type. For example if I have a variable named “number” that is a number, I can’t assign a string to it. It can only be a number.

    Weakly typed languages, such as JavaScript and Python are incredibly difficult to properly scan. These are languages where I can assign the string “potato” to my variable named “number”. While weakly typed languages offer great flexibility to developers, they are a nightmare for code scanners.

  • Part 3: Composition scanning

    If you just showed up here, go back and start at the intro post, you’ll want the missing context before reading this article.

    In this post we’re going to talk about a newer type of scanner called a composition scanner. The idea here is when you build an application today it’s never just what you wrote. It also includes source code from a large number of other sources. Usually these other sources are open source.

    A composition scanner will look at your project, specifically the things you didn’t write, and attempt to alert you if you are including components that have known security vulnerabilities. It’s very common to not upgrade the open source we put into our projects. Upgrading is hard and can break things, so doing nothing is easier most of the time. Composition scanners let us see what’s hiding in the depths of our project, sometimes it isn’t very pretty.

    An easy example we can use is if you are including OpenSSL code in your application. Do you know if the version of OpenSSL you are using is still vulnerable to Heartbleed? You probably can’t say for certain if this is true or not, but a composition scanner probably can.

  • Daniel Stenberg: curl 7.69.1 better patch than sorry

    Quite obviously this release was not shipped aligned with our standard 8-week cycle. The reason is that we had too many semi-serious or at least annoying bugs that were reported early on after the 7.69.0 release last week. They made me think our users will appreciate a quick follow-up that addresses them. See below for more details on some of those flaws.

    How can this happen in a project that soon is 22 years old, that has thousands of tests, dozens of developers and 70+ CI jobs for every single commit?

    The short answer is that we don’t have enough tests that cover enough use cases and transfer scenarios, or put another way: curl and libcurl are very capable tools that can deal with a nearly infinite number of different combinations of protocols, transfers and bytes over the wire. It is really hard to cover all cases.


    This was an out-of-schedule release but the plan is to stick to the established release schedule, which will have the effect that the coming release window will be one week shorter than usual and the full cycle will complete in 7 weeks instead of 8.

And with everything now relying on internet-connectivity, companies can often give up on supporting devices entirely, often leaving users with very expensive paperweights as we saw after Google acquired Revolv.

    No less than 98 per cent of traffic sent by internet-of-things (IoT) devices is unencrypted, exposing huge quantities of personal and confidential data to potential attackers, fresh analysis has revealed.

    What’s more, most networks mix IoT devices with more traditional IT assets like laptops, desktops and mobile devices, exposing those networks to malware from both ends: a vulnerable IoT device can infect PCs; and an unpatched laptop could give an attacker access to IoT devices - and vast quantities of saleable data.

    Those are the big conclusions from a real-world test of 1.2 million IoT devices across thousands of physical locations in the United States, carried out by Palo Alto Networks.

Canonical Promotions of TTX Exercises and ESM

  • On Boxing, Tabletop Exercises and Threat Models

    At Canonical we have recently performed a series of cyber tabletop exercises (TTX). A TTX is an information security preparedness drill where a cyber incident scenario is played out to improve your tactics, techniques and procedures (TTPs). When performing a TTX it is important to use the same amount of staff and effort as though a real incident were occuring. This helps to uncover deficiencies in your TTPs and address those issues before a real event occurs. Being as efficient as possible is critical during incident response because as time passes data that can help determine root cause is lost and the attacker may still be causing harm to the environment.

    This past month we performed two TTXs with different groups within Canonical. This type of exercise requires support from the top down, you will be interrupting work for up to a day and it is imperative that the management of each team is behind this effort. At Canonical security is in our DNA and this exercise was performed with full support of everyone within the company.

As an experiment I created a time limited discount coupon so that all listeners could buy it with €10 off. As you can tell from the graph it did have an immediate response, which again proves that marketing and visibility are the things that actually matter when trying to sell any product. After that we have the "new normal", which means no sales at all. I don't know if this is caused by the coronavirus isolation or whether this is the natural end of life for the product (hopefully the former but you can never really tell in advance).

  • Shing Lyu: Lessons learned in writing my first book

    You might have noticed that I didn’t update this blog frequently in the past year. It’s not because I’m lazy, but I focused all my creative energy on writing this book: Practical Rust Projects. The book is now available on Apress, Amazon and O’Reilly. In this post, I’ll share some of the lessons I learned in writing this book. Although I’ve been writing Rust for quite a few years, I haven’t really studied the internals of the Rust language itself. Many of the Rust enthusiasts whom I know seem to be having much fun appreciating how the language is designed and built. But I take more joy in using the language to build tangible things. Therefore, I’ve been thinking about writing a cookbook-style book on how to build practical projects with Rust, ever since I finished the video course Building Reusable Code with Rust. Out of my surprise, I received an email from Steve Anglin, an acquisition editor from Apress, in April 2019. He initially asked me to write a book on the RustPython project. But the project was still growing rapidly thanks to the contributors. I’ve already lost grip on the overall architecture, so I can’t really write much about it. So I proposed the topic I have in mind to Steve. Fortunately, the editorial board accepted my proposal, and we decided to write two books: one for general Rust projects and one for web-related Rust projects. Since this is my first time writing a book that will be published in physical form (or as The Rust Book put it, “dead tree form”), I learned quite a lot throughout the process. Hopefully, these points will help you if you are considering or are already writing your own book.
