ZFS for Linux has truly arived with Debian now with ZFS on Linux included

The package is called zfs-linux and is currently available to Debian unstable users. Package details via the Debian Tracker. Additional commentary about this achievement by Debian developer Petter Reinholdtsen on his blog.

Today, after many years of hard work from many people, ZFS for Linux finally entered Debian. The package status can be seen on the package tracker for zfs-linux. and the team status page. If you want to help out, please join us. The source code is available via git on Alioth. It would also be great if you could help out with the dkms package, as it is an important piece of the puzzle to get ZFS working.

Basline H264 in Fedora Workstation… But what’s the point?

So after a lot of work to put the policies and pieces in place we are now giving Fedora users access to the OpenH264 plugin

UnitedRPMs – New RPMFusion Alternative for Fedora 24/25:

The UnitedRPMs repository provide the most popular multimedia packages for Fedora 24 and Rawhide: vlc, mpv, GNOME-mpv, smplayer, kdenlive, handbrake, deadbeef, foobnix, kdenlive and others.

  • United RPMS by UnitedRPMs

  • No GPG signatures, that’s a no no in our book.

  • No separation of free and non-free packages. But that’s not really why your using something like UnitedRPMs.

  • As an example, once the repo UnitedRPMs’ repo is setup, you can install gstream and the all the codecs for all the things:

dnf install gstreamer{1,}-{ffmpeg,libav,plugins-{good,ugly,bad{,-free,-nonfree}}} --setopt=strict=0

State Department shuts down its e-mail system amid concerns about hacking – The Washington Post

The State Department scrambled over the weekend to secure its unclassified e-mails, shutting down the entire e-mail system after finding evidence suggesting a hacker may have been been poking around.

A senior State Department official said technicians recently detected “activity of concern” in portions of the system handling unclassified e-mail. The official, who you could also consider a leaker, remains unindfied saying that none of the department’s classified systems were compromised.

VP8 and H.264 to both become mandatory for WebRTC | Andreas Gal

WebRTC is mainly about opening direct connections to other web browsers. The plug-inless capture of video and audio is related but the fundmentals of it are implmented by each browser.

Unfortunately, the full potential of the WebRTC ecosystem has been held back by a long-running disagreement about which video codec should be mandatory to implement. The mandatory to implement audio codecs were chosen over two years ago with relatively little contention: the legacy codec G.711 and Opus, an advanced codec co-designed by Mozilla engineers. The IETF RTCWEB Working Group has been deadlocked for years over whether to pick VP8 or H.264 for the video side.

At the last IETF meeting in Hawaii the RTCWEB working group reached strong consensus to follow in our footsteps and make support for both H.264 and VP8 mandatory for browsers. This compromises was put forward by Mozilla, Cisco and Google. The details are a little bit complicated, but here’s the executive summary:

  • Browsers will be required to support both H.264 and VP8 for WebRTC.
  • Non-browser WebRTC endpoints will be required to support both H.264 and VP8. However, if either codec becomes definitely royalty free (with no outstanding credible non-RF patent claims) then endpoints will only have to do that codec.
  • “WebRTC-compatible” endpoints will be allowed to do either codec, both, or neither.

See the complete proposal by Mozilla Principal Engineer Adam Roach here. There are still a few procedural issues to resolve, but given the level of support in the room, things are looking good.

Mobile Pwn2Own 2014: Windows Phone’s sandbox resists attack

The Mobile Pwn2Own 2014 hacking competition, held at the PacSec Applied Security Conference in Tokyo, Japan, was concluded on Thursday, and not one of the targeted phones has survived completely unscathed.

Of the targets available for selection, Amazon Fire Phone, Apple iPhone 5S, Samsung Galaxy S5, and Google/LG Nexus were completely “pwned,” the Nokia Lumia 1520 running Windows Phone partially, and BlackBerry Z30, Apple’s iPad Mini and the Nexus 7 weren’t targeted at all.

A successful exploitation of a bug in the latter carried with it a $150,000 prize, the others less: $100,000 for messaging services, $75,000 for short distance and $50,000 for the browser, apps or OS.

What we know is that the Apple iPhone 5S was owned via the Safari browser by exploiting two bugs, the Amazon Fire Phone was breached via three bugs in its browser, Samsung Galaxy S5 was successfully targeted via NFC by two different teams (one by triggering a deserialization issue in certain code, and the other by targeting a logical error), and the Nexus 5 was forced to pair with another phone via Bluetooth.

The two contestants that did their attacks on the second day were less successful: Jüri Aedla used Wi-Fi to target a Nexus 5, but was unable to elevate his privileges further than their original level. And Nico Joly tried to exploit Lumia’s browser, but didn’t manage to gain full control of the system as the sandbox held. He did, however, manage to extract the cookie database.

AT&T Stops Using ‘Perma-Cookies’ to Track Customer Web Activity – Mac Rumors

In late October, researchers discovered that AT&T and Verizon had been engaging in some unsavory customer tracking methods, using unique identifying numbers or “perma-cookies” to track the websites that customers visited on their cellular devices to deliver target advertisements.

Following significant negative attention from the media, AT&T today told the Associated Press that it is no longer injecting the hidden web tracking codes into the data sent from its customers’ devices.

The change by AT&T essentially removes a hidden string of letters and numbers that are passed along to websites that a consumer visits. It can be used to track subscribers across the Internet, a lucrative data-mining opportunity for advertisers that could still reveal users’ identities based on their browsing habits.

AT&T’s customer tracking practices, called “Relevant Advertising,” were the result of a pilot program the company had been experimenting with, which has apparently come to an end.

While AT&T has opted to stop using the invasive tracking method, Verizon is continuing to utilize perma-cookies to track the web activity of its customers. Unlike AT&T’s experimental program, Verizon has been using Relevant Advertising techniques for approximately two years.

French Security Firm Vupen discovers and collects zero day exploits then sells them to intelligence agencies

  • At Google’s recent hack-a-thon, they offered $60,000 for each bug in Chrome that hackers disclosed to them, so that they would fix them
  • Vupen (whose name stands for “vulnerability research” and “penetration testing”) was at the conference, and had an exploit for Chrome, however they said “We wouldn’t share this with Google for even $1 million, We don’t want to give them any knowledge that can help them in fixing this exploit or other similar exploits. We want to keep this for our customers.”
  • Vupen claims to only sell to NATO governments and their partners and that they have a strict policy of only dealing with democratic governments, however they admits that their exploits could fall into the wrong hands
  • Many make analogies of Vupen as a Cyber Warfare Arms Dealer
  • The problem with selling weapons is that they can then be transferred to other parties, a situation illustrated last year when telecom surveillance gear from Blue Coat Systems was sold to a United Arab Emirates firm but ended up being used to tracking political dissidents in Syria
  • Governments pay a $100,000/year subscription for access to the catalogue of zero day exploits
  • Each individual exploit must be purchased separately and is not sold exclusively, meaning that the other Vupen customers have access to it as well
  • Vupen claims to have off the self undisclosed vulnerabilities in Micro­soft Word, Adobe Reader, Google’s ­Android, Apple’s iOS and every major browser
  • Most exploits sell for far in excess of the 6 figure subscription you pay just to find out about their existence
  • When Vupen started in 2008 the company and its researchers initially worked with some software vendors to patch the flaws. However after taking $1.5 million in venture capital from 360 Capital Partners and Gant & Partners, the firm found that it could earn far more by keeping its findings under wraps and selling them at a premium

Anti-dissident Malware spread via Skype in Syria

  • Hackers loyal to the government of Syria have taken to spreading malware to dissidents via Skype
  • The tool that purports to allow you to change your MAC address to better hide your identity and avoid detection by the government, is actually a standard RAT trojan, and gives the attacks full control over your system, including keylogging and access to your documents
  • The trojan connects to a command and control server in Syria hosted in an IP range belonging to the Government Owned Syrian Telecommunications Establishment
  • Other malware also distributed via skype chats carries a facebook icon, but installs a different malware variant
  • The attackers seem to be using Skype as a method of social engineering and tricking users in to running the files, they do not appear to have exploited Skype in any way.

First ever trans-arctic fibre lines will be installed this summer

  • The cables are called Artic Fibre and Arctic Link and will cross the Canadian Northwest Passage. A third cable, ROTACS (Russian Optical Trans-Arctic Submarine Cable System), will skirt the north coast of Scandinavia and Russia.
  • The completed cables are estimated to cost between $600 million and $1.5 billion each
  • The new cables will reduce the internet latency between London, England and Tokyo, Japan from the current average of 230 ms by approximately 60ms (30%) to 170ms
  • The reduced latency will benefit financial markets and automated trading as well as increasing the available bandwidth
  • These new fibres will also offer much needed redundancy, currently all fibre between Europe and Asia goes through choke points in the Middle East or the Luzon Strait between the Philippine and South China seas

Q: (Bilbo) How does HLS (HTTP Live Streaming) work?
A: ScaleEngine has offered an HLS stream for JupiterBroadcasting for quite some time, but HLS was only implemented by Apple’s iOS at the time. Since then, some Android 3.x and all Android 4.x devices have added support for the protocol. This week, version 2.0.1 of VLC was released which fixed the last remaining bug that prevented the stream from working. It is now possible to watch the live stream reliably from your desktop via VLC, as well as from most mobile devices and tablets. Unlike the original VLC stream we offered, which used the RTSP protocol, the HLS stream is much smoother. RTSP used separate connections for audio and video, which could cause them to get out of sync, and RTSP was notorious for working poorly through NAT.

And HLS stream relies on a process called packetization, where the live video stream is divided into separate small files, called segments. The default segment size is 10 seconds. So in an HLS stream, the first request to our server returns a playlist, detailing the different streams that are offered (if multiple bit rates are offered, if there is an audio only version, etc). Your device then creates a session and requests the appropriate stream playlist. This playlist will contain the most recent segments of the live stream, and look something like this:

#EXTM3U
#EXT-X-ALLOW-CACHE:NO
#EXT-X-TARGETDURATION:3
#EXT-X-MEDIA-SEQUENCE:698
#EXTINF:3,
media_698.ts?wowzasessionid=418744583
#EXTINF:3,
media_699.ts?wowzasessionid=418744583
#EXTINF:3,
media_700.ts?wowzasessionid=418744583

As you can see here, the playlist contains 3 segments, each 3 seconds long. Your client will start by requesting the first, and continue requesting each segment on the playlist (the number of segments on the playlist is adjustable server side). Once your client has requested all of the segments on the last playlist, it will request the next playlist, which will contain new segments.

Your player will start playing as soon as the first segment is ready, and will continue adding new segments to the end of the buffer as it plays, attempting to keep up or ahead of the playback.

This effect can be best demonstrated by the VLC debugging output:
