Hackers use dangerous Petya ransomware in targeted attacks

In a case of no honor among thieves, a group of attackers has found a way to hijack the Petya ransomware and use it in targeted attacks against companies without the program creators' knowledge.A computer Trojan dubbed PetrWrap, being used in attacks against enterprise networks, installs Petya on computers and then patches it on the fly to suit its needs, according to security researchers from antivirus vendor Kaspersky Lab.The Trojan uses programmatic methods to trick Petya to use a different encryption key than the one its original creators have embedded inside its code. This ensures that only the PetrWrap attackers can restore the affected computers to their previous state.To read this article in full or to leave a comment, please click here

How the IETF community is shaping technology to build a better society

The continued advancement in technological landscape enabling more people having Internet access in the global arena has meant that IETF (Internet Engineering Task Force) remains at the forefront of integrating technology with humanity. In fact, IETF has made significant use of social dimension to articulate its area of work and research. It is beautifully reflected in section 4.1 of the RFC 3935 wherein it states that “We want the Internet to be useful for communities that share our commitment to openness and fairness.  We embrace technical concepts such as decentralized control, edge-user empowerment and sharing of resources, because those concepts resonate with the core values of the IETF community”.

On the ‘net: PCEP

The original Path Control Element Protocol (PCEP) work dates from the early 2000’s, with the first IETF RFC (4655) being made informational in 2006—which means PCEP predates the time when SDNs were “cool.” PCEP was originally, because of the increasingly complex nature of computing Traffic Engineering (TE) paths through (primarily), Service Provider (SP) networks. Three specific developments drove the design, standardization, and deployment of PCEP —ECI Blog

Docker Turns 4: Thank you Docker Community!

In case you missed it, this week we’re celebrating Docker’s 4th Birthday with meetups all over the world (check out #dockerbday on twitter). This feels like the right time to look back at the past 4 years and reflect on what makes the Docker Community so unique and vibrant: people, values, mentorship and learning opportunities. You can read our own Jérôme Petazzoni’s blog post for a more technical retrospective.

Docker Birthday

Managing an open source project at that scale and preserving a healthy community doesn’t come without challenges. Last year, Arnaud Porterie wrote a very interesting 3-part series blog post on open source at Docker covering the different challenges associated with the People, the Process and the Tooling and Automation. The most important aspect of all being the people.

Respect, fairness and openness are essential values required to create a welcoming environment for professionals and hobbyists alike. In that spirit, we’ve launched a scholarship program and partnerships in an attempt to improve opportunities for underrepresented groups in the tech industry while helping the Docker Community become more diverse. If you’re interested in this topic, we’re fortunate enough to have Austin area high school student Kate Hirschfeld presenting at DockerCon on Diversity Continue reading

Review: Microsoft Teams almost as bad as its beta

For months now, we’ve been hearing about Microsoft Teams, Microsoft’s much-heralded Slack killer for corporate chat. It’s now in official release (what Microsoft calls “general availability”) as part of Microsoft’s Office 365 enterprise plans. Sadly, Teams is underwhelming in its formal debut and definitely not a match for the hype Microsoft has been providing since October 2016. For a product so late to market, Microsoft should have delivered much more.To read this article in full or to leave a comment, please click here(Insider Story)

Taking A Stand Against Corruption

Over the last few months, I’ve noticed that some pages on this site have been returning what appear to be corrupted pages, looking something like this:

Corrupted Page

 

Or like this:

 

Pretty, aren’t they? Typically if the user hits refresh the page will come back as it should have done first time. I’ve been working for many weeks now to track down why this was happening. One thing I noted is that the corrupted files were smaller than the non-corrupted equivalent, suggesting that the file was either truncated or, more likely, compressed. Opening a downloaded file in a text editor showed that the header of these corrupted pages begins like this:

Some of you are probably feeling smug right now because you know that the first three bytes of a gzip file are 1F 8B 08. The ASCII code for 0x1F is Ctrl-_; there’s no code for 0x8B; ASCII 0x08 is the same as Ctrl-H (i.e. backspace). This should look familiar in the image above:  ^_ <8B> ^H. In other words, the client is receiving a GZIPped version of the page but presumably was told that the mime type was text/html. The end result is the garbled mess we saw above. So now Continue reading

Open-source BeagleBone Blue board aims for robots, drones

Before Raspberry Pi, BeagleBone was the go-to low-cost developer board for enthusiasts. It's still used by many, and a new BeagleBone board is now being targeted at robots.The US $79.95 BeagleBone Blue from BeagleBoard.org is a credit-card sized board with all the components needed to operate a robot or even a drone. It is open source, as its schematics have been published, and developers can replicate the board.Robots have unique requirements, and some computer boards specialize in specific features. For example, Nvidia's Jetson TX2 and Intel's Joule excel at computer vision and can give robots digital eyes to steer past obstacles. These boards also have powerful graphics processors and 64-bit CPUs.To read this article in full or to leave a comment, please click here

Cloud price wars are back on

At the Google NEXT cloud conference last week the company announced new Committed Use Discounts (CUDs) in which customers receive a reduced rate on virtual machine rentals in exchange for signing a one or three year contract.+MORE AT NETWORK WORLD: 10 Ways Google improved its cloud at its big NEXT conference +It’s not a completely novel concept because Microsoft offers enterprise agreements and Amazon Web Services has Reserved Instances, which are a similar concept.One of the main arguments Google made was that its CUDs are more flexible than competitors though. Users don’t have to commit to a specific virtual machine instance type for three years, the company said. Instead, they just estimate how much aggregate virtual compute and/or memory they will use over the life of the contract. CUDs are in beta in Google’s cloud, you can read more about them here.To read this article in full or to leave a comment, please click here

IDG Contributor Network: Datadog reduces the alert noise for IT support workers

The move to more complex and distributed applications has done wonders for organizational agility and the ability to innovate, but it has also had some flow-on effects for those poor people responsible for managing application uptime on a day to day basis.Lots of disparate application components means lots of new potential sources of error, and people who carry a pager to be alerted of any issues suffer an increasing number of ill-timed calls.+ Also on Network World: Application monitoring becomes table stakes in the digital age + A new offering from application monitoring vendor Datadog seeks to change this paradigm by offering a far more flexible alerting approach. Datadog’s new composite alert feature is intended to reduce alert noise for DevOps and operations teams. The idea being that these practitioners will have less call to spend time on insignificant alerts and will be alerted of orly major issues. In a kind of “boy who cried wolf” metaphor, this should result in better response to issues that matter.To read this article in full or to leave a comment, please click here

IDG Contributor Network: Another 911 outage. Does any accountability exist?

AT&T Wireless customers who tried to reach 911 in the evening hours of Wednesday, March 8, were left stranded in more than a dozen major cities. Based on unconfirmed, but widespread reports, the problem may have affected callers nationwide, with AT&T only sending out tweets again and again, stating: [AT&T is aware] of issue affecting some calls to 911 for wireless customers. Working to resolve ASAP. We apologize to those affected.  With no root cause offered, several public safety agencies and citizens were left confused on what to do. In what has become a natural reaction to any traumatic event, both the general public and several agencies took to Twitter, Facebook and other social media outlets on the web as the go-to place for help, as well as an outlet for frustration—with many announcing their intentions to switch carriers.To read this article in full or to leave a comment, please click here
