New 'USG' Firewalls Protect USB Drives From Malicious Attacks
by Peter Reutemann 12 Mar '17

12 Mar '17

'A developer has created the USG, "a small, portable hardware USB firewall...to prevent malicious USB sticks and devices laden with malware from infecting your computer." An anonymous reader quotes ZDNet: The problem is that most computers automatically trust every USB device that's plugged in, which means malicious code can run without warning... Cars, cash registers, and some ATMs also come with USB ports, all of which can be vulnerable to cyberattacks from a single USB stick. That's where the USG firewall comes in...a simple hardware serial link that only accepts a very few select number of safe commands, which prevents the device from executing system commands or intercepting network traffic. That means the data can flow from the USB device, but [it] effectively blocks other USB exploits. The firmware has been open sourced, and the technical specifications have also been released online "to allow anyone to build their own from readily available development boards."' -- source: https://hardware.slashdot.org/story/17/03/11/1658238 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Munich's IT Lead: 'No Compelling Reason' To Switch Back To Windows From Linux
by Peter Reutemann 12 Mar '17

12 Mar '17

'"The man who runs Munich's central IT says there is no practical reason for the city to write off millions of euros and years of work to ditch its Linux-based OS for Windows," reports TechRepublic. Long-time Slashdot reader Qbertino summarizes a German-language article: Karl-Heinz Schneider, lead of Munich's local system house company IT(a)M, goes on to claim, "We do not see pressing technical reasons to switch to MS and MS Office... The council [in their recent plans] didn't even follow the analysts' suggestion to stick with using LibreOffice." Furthermore, Schneider stated that "System failures that angered citizens in recent years never were related to the LiMux project, but due to new bureaucratic procedures..." and apparently decisions by unqualified personnel at the administrative level, as Munich's administration itself states.' -- source: https://linux.slashdot.org/story/17/03/11/0142247 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Linux Foundation Chief: Businesses 'Will Fail' If They Don't Use Open Source Code
by Peter Reutemann 12 Mar '17

12 Mar '17

'First Vint Cert said there's a "thread of openness" that runs throughout the internet, adding that "the internet, itself, has open characteristics" and thrives on "permissionless innovation." And Eric Brewer, vice president of infrastructure at Google, touched on the same themes, according to Tech Republic. "Linux, Brewer said, won some of the early internet wars because it was open, but also because it was the most innovative of its time. He also said that companies should work with open source for the value of the ecosystem and community, not just the value of the code." Then Linux Foundation executive director Jim Zemlin told the audience that business models were already changing to include open source, and ultimately made the argument that organizations that "don't harvest the shared innovation" of open source "will fail."

Sensible Password Rules
by Lawrence D'Oliveiro 11 Mar '17

11 Mar '17

NIST came out last year with some guidelines on how to choose passwords <https://nakedsecurity.sophos.com/2016/08/18/nists-new-password-rules-what-y…>. The “dos” should not be too surprising, but it is worth mentioning the “don’ts”: * No restrictions on what characters are allowed * No password hints * No knowledge-based authentication * No expiration without some good reason Also, they are no longer recommending the use of SMS for two-factor authentication. I wonder what you should use instead?

Look before you paste from a website to terminal
by Peter Reutemann 11 Mar '17

'Most of the time when we see a code snippet online to do something, we often blindly copy paste it to the terminal. Even the tech savy ones just see it on the website before copy pasting. Here is why you shouldn't do this.' -- source: https://lifepluslinux.blogspot.co.nz/2017/01/look-before-you-paste-from-web… Hint: hidden commands thanks to HTML/CSS.

Microsoft Continues Porting Visual C++ To Linux
by Peter Reutemann 11 Mar '17

11 Mar '17

'Long-time Slashdot reader Billly Gates shared some news from Microsoft's Visual C++ blog: Visual Studio 2017 now lets developers write C++ code for Linux desktops, servers, and other devices without an extension, targeting specific architectures, including ARM: Visual Studio will automatically copy and remotely build your sources and can launch your application with the debugger... Today Visual Studio only supports building remotely on the Linux target machine. It is not limited to specific Linux distros, but we do have dependencies on the presence of some tools. Specifically, we need openssh-server, g++, gdb and gdbserver.

US ISP Verizon Wireless To Stop Giving Out Static IPv4 Addresses
by Lawrence D'Oliveiro 10 Mar '17

10 Mar '17

New business customers with Verizon Wireless will no longer get static IPv4 addresses. Instead, they will get “persistent prefix” IPv6 addresses <https://www.theregister.co.uk/2017/03/10/verizon_running_out_of_ipv4_addres…>. I assume “persistent prefix” means they get a fixed value for the top 48 bits, and they can do what they like with the bottom 80 bits. This /48 subnet allocation seems to be the common thing for IPv6.

In the wake of the plan floated by the US Government to demand passwords to social media accounts from people wanting to enter the country, here <http://freedom-to-tinker.com/2017/02/10/engineering-around-social-media-bor…> is a discussion of some likely countermeasures that should still give the cover of plausible deniability.

“One of the reasons society hasn't destroyed itself is that people with intelligence and skills tend to not be criminals for a living. If it ever became a viable career path, we're doomed.” -- Bruce Schneier <https://www.schneier.com/blog/archives/2017/03/building_smarte.html>
