Russia to Ban Windows from Government PCs

Another radical change that German Klimenko wants to achieve is replacing Windows on all government PCs with a Linux-based operating system developed by Russia. Klimenko also stated that there are already 22,000 municipal authorities ready to replace Windows with their own operating system.

Open Source WiFi Router with Open Source Code

Our goal is to let Geek Force Board with all popular open source systems and every one can use free open source codes, including OPENWRT, Android, Ubuntu Snappy to make their own Roboto Multimedia WiFi Router Gateway Board.

3 Mini PCIe Slots
WiFi
BLE
LTE
Quad Cortex A7 1.3Ghz

Geek Force Board is designed for IoT Home Multimedia and Home Automation. With powerful Quad-core ARM Cotex-A7 1.3MHz made by Mediatek MT7623, could reach below applications (including TOR, VPN functions).

We are engaged in WiFi field for long time and would like to go with IoT trend. More and more IoT devices need a powerful gateway to link together and with media content bandwidth need.

With those interfaces, you can contribute your own roboto multimedia router.

Hardware is difficult, and we also would like to provide good Open Source firmwares (OPENWRT, Android, Ubuntu Snappy core) tuned for more people to implement their own systems.

OpenShot 2.0 Beta Now Available

OpenShot 2.0 has a new beta build available for testing.

The update is the third full beta release of the revamped video editor but only the first to made available for public testing.

Among the features, fixes and improvements that are new in OpenShot 2.0.6: –

Smoother animations (zooming, panning, rotation)
Audio improvements
Autosave engine automatically saves your project at set intervals
Automatic project back-up and recovery
Support for importing/exporting Openshot projects across OSes
New Audio preview settings
Prompt when the application needs to “restart” for an option to take effect
Anonymous metric and error reporting enabled by default (can be disabled)
3 Years In The Making: OpenShot 2.0 Finally Hits Beta

It’s the first major release of the non-linear video editing tool in three years, and the first to arrive since the project successfully met its funding goal in the OpenShot Kickstarter campaign held in 2013.

We’ve seen the launch of professional-grade and pseudo-open source Lightworks video editor, huge improvements made to Qt-based Kdenlive, and even user-friendly Pitivi hasn’t been shy in pushing forward.

No one app suits everyone, and for this reason if no other it is great to see OpenShot back.

To install OpenShot 2.0 on Ubuntu 14.04 or later run the following two commands in a new Terminal window

sudo add-apt-repository ppa:openshot.developers/libopenshot-daily

sudo apt-get update && sudo apt-get install openshot-qt

Android Phone Makers will Switch to Linux

Factory and deliver devices powered by Ubuntu.

The Linux shop has received commitments from Android smartphone and tablet makers to ship devices using its Linux with devices “later this year.”

Chief executive Jane Silber told The Register: “We are talking to them [Android OEM partners] regularly and many will be shipping Ubuntu phones. There’s a lot of interest from these folks in supporting another platform.”

The company announced the Ubuntu variant of BQ’s M10 Aquarius tablet last week. BQ, an Ubuntu partner of two years, also ships M10 on Android. BQ was already selling two handsets running Ubuntu.

Canonical is also partnering with Android partner Meizu, which is shipping the MX4.

Mozilla said last week it’s stopping production of Firefox OS for smartphones, having had enough of trying to play catch up despite having had the muscle of Telefonica to help push it. Firefox OS was a Linux-based operating system that ran HTML5. Firefox OS will now go on “things” – starting with UHD TVs from Panasonic.

She would not say which of Google’s partners, currently making and selling Android phones and tablets, that Canonical has talked to, or which of those will embrace Ubuntu. However, Samsung – the biggest single beneficiary of Android on smartphones since the Galaxy – has made repeated noises about need for an alternative.

To date, Samsung has backed Tizen, which started as LiMo and received Intel’s backing in 2011 when the project was given the Tizen rebrand.

Silber is also dismissive of the suggestion Canonical and Ubuntu haven’t exactly triumphed in their various efforts to flip Mac or Windows loyalists. The goal in 2011 was for 200 million Ubuntu users by the end of that year – but today that figure, according to Canonical, is just 30 million desktops.

“Five years ago people said, why do you need another Linux distro?”

SourceForge Acquisition and Future Plans

Our first order of business was to terminate the “DevShare” program. As of last week, the DevShare program was completely eliminated. The DevShare program delivered installer bundles as part of the download for participating projects. We want to restore our reputation as a trusted home for open source software, and this was a clear first step towards that.

Italian hacker publishes 10+ 0 day SCADA exploits with proof of concept code

SCADA (Supervisory Control and Data Acquisition) are Industrial control systems
The Stuxnet worm targeted the specific SCADA system used by the Iranian centrifuges
These exploits could cause serious disruption if the systems are not properly protected from external access
SCADA systems are used to control numerous important industrial systems including water and sewage treatment, dams and power plants, as well as manufacturing automation systems.
In January 2000, the remote compromised of a SCADA system was responsible for pumping sewage into a nearby park and contaminated an open surface-water drainage ditch.

Official uTorrent website compromised, users download spyware

On or before Tuesday September 13th, the Official uTorrent.com website was compromised, and on the 13th, the attackers replaced the download files with spyware.
Users who downloaded uTorrent on the 13th instead received a scareware fake anti-virus package called ‘Security Shield’
The scareware told them they were infected with malware and demanded payment to remove it
Any users who downloaded uTorrent between 12.20 and 14.10 BST likely received the malware instead of uTorrent.
In this case, the attack was fairly obvious, but a similar hack against popular software distribution points could have resulted in the stealth infection of 1000s of systems via the auto-update feature built in to most modern applications.
This is always the nightmare security situation, when legitimate trusted sites are compromised and start to distribute harmful content.

Funny Virus Pic – Google+

BIOS rootkit found in the wild

The virus can infect most any computer with an Award BIOS (very popular, used in most all Motherboards that I own).
The virus dumps a copy of the BIOS, and then adds an ISA ROM that will rewrite the MBR (Master Boot Record) on the hard drive at each bootup.
The MBR virus then rootkits winlogon.exe to take over control of the system
The rootkit then prevents modification of the MBR, making it harder to remove the virus
Even if the MBR is repaired, it is reinfected at the next boot by the BIOS portion of the virus
The rootkit also downloads a trojan and allows the system to be remotely controlled.
This attack is related to the attack we discussed in a previous episode of TechSNAP where a researcher was able to infect the battery in a MacBook with a virus. If the virus was similar to this one, it would add an additional layer of complexity, if the BIOS could be reinfected from the battery.

TWiT.tv compromised, malicious iframe injected, loads Java malware

The popular TWiT.tv page was compromised and a snippet of malicious code was added, an iframe that directed users’ browsers to a page that attempted to use Java and PDF exploits.
Google’s safe browsing started blocking the site. Firefox and Google Chrome users will be presented with a warning before visiting the site.

War Story:

At approximately 4:00 PM facility local time on Sunday, September 11, 2011, the Seattle 1 data center experienced an unexpected service interruption. It was determined that the cause of the issue was a malfunction in one of the edge routers servicing the facility.
The device was rebooted to correct the issue and we proceeded to work with the device manufacturers TAC (Technical Assistance Center) to determine the cause of the issue and proper resolution to avert any future problems.
At 6:20 PM facility local time, the same issue occurred again, and the device was again rebooted.
To prevent any future unexpected service interruptions, it was decided that the best course of action would be to replace the device with the standby device available at the facility.
At approximately 7:00 PM facility local time, we began the process of replacing the faulting device with a new one. The old device was removed and the new device was put in its place.
Once powered on the replacement device alerted us to a number of errors within the switch fabric modules that were causing inter-line card communication to not work properly.
We again contacted the device manufactures TAC, and at approximately 8:30 PM, we decided with the TAC that the best option was to replace the switch fabrics in the replacement device with the switch fabrics from the old device.
Once this was completed the device was restarted but produced the same errors.
The issue was then escalated to tier 2 support at the device manufactures TAC.
We concluded that the issue was likely a problem somewhere within the replacement device’s chassis, and proceeded to replace the chassis with the one from the old device.
Upon doing so, we began getting a different set of errors, this time with the management modules communication to the line cards.
At approximately 4:30 AM facility local time, the matter was escalated to tier 3 support at the device manufactures TAC. At this time, we also dispatched our head network technician to the facility from Phoenix with a spare device which is stored at our office in the event of issues such as this one.
At approximately 6:30 AM facility local time, the TAC tier 3 technician concluded that the likely cause of the issue was an electrical problem either within the switch fabric modules or the replacement device chassis which resulted in improper current being sent to various parts of the device and damaging several of the sensitive electronic components in the line card, forwarding engines and switch fabrics. Because the electrical subsystem within the device had potentially caused damage to all of the switch fabric modules that we had available at the facility, we were advised that we should power down both devices and not use either of them any further until a full diagnostic of the electrical sub-system could be completed by the manufacturer.
At approximately 12:00 PM our head network technician arrived at the Seattle airport, and by 1:00 PM was at the facility with the replacement device from our Phoenix office.
At approximately 2:00 PM our head network technician completed the installation of the replacement device from our Phoenix office and service was fully restored.
Total time offline: 19 hours 8 minutes.

A few questions about home servers
Q: crshbndct I’ve built a spare computer out of some spare parts and I want to use it as a home server. I’d like to use it as a router, a DNS server, a caching server, and maybe also throttle the usage of my servers. What should I use?
A: Chris and I both love pfSense, it is a FreeBSD based router appliance. You can basically turn any computer with 2 network cards into a Router/Firewall, with DHCP, DNS/DDNS, VPN (IPSec, PPTP, OpenVNP), VLANs, Captive Portal, Traffic Shaping and Graphing. It has a web interface similar but more expansive than what most people are already used to from a normal off the shelf home router.

Next Week: RAID types, what they are and some use cases for each.
