IDG Contributor Network: SwiftStack ramps up its hybrid cloud offerings

This week sees Amazon Web Services (AWS) holding its annual re:Invent conference in sunny Las Vegas. Since AWS is the public cloud vendor that everyone agrees rules the roost, it is unsurprising to see a huge proliferation of pitches in my inbox all hanging off the AWS event.Some of these pitches are completely irrelevant to re:Invent (“this new aftershave for men is designed for the public cloud”), while others are far more related to the fundamental change in the way that technology is done that AWS represents.+ Also on Network World: How to make hybrid cloud work + A case in point is SwiftStack's announcement regarding its offerings designed to ease hybrid cloud adoption.To read this article in full or to leave a comment, please click here

Researchers exploit app flaw and steal a Tesla Model S

In September, Chinese researchers from Keen Security Lab showed how a Tesla Model S could be remotely hacked while it was being driven. The hack demonstrated by Promon, a Norwegian security company, provided “additional functionality” for cyber thugs to control the vehicle, including enabling “keyless driving functionality,” which could allow a crook to drive away with a Tesla without have a key fob present.To read this article in full or to leave a comment, please click here

IDG Contributor Network: Are we in a golden age of open source or just openwashing?

We are witnessing a golden age of open source. Never in the history of the technology industry have we seen so many developers coding in the open, jointly working on common codebases that can be leveraged by any individual user or company.This trend is a huge step forward, with broad benefits to both the user and vendor community. It is spurring significantly greater innovation and interoperability across solutions. + Also on Network World: The shift in open source: A new kind of platform war + Our entire industry has fallen in love with all things open, especially open source. Linux has become all-pervasive from supercomputers to GoPros to vehicles, and new open-source projects are sprouting like daylilies in the Texas summer.

Worth Reading: Personalized Ransomware

Smart entrepreneurs have long employed differential pricing strategies to get more money from customers they think will pay a higher price. Cyber criminals have been doing the same thing on a small scale with ransomware: demanding a larger ransom from individuals or companies flush with cash, or organizations especially sensitive to downtime and service disruptions. But now it appears cyber criminals have figured out how to improve their ROI by attaching basic price discrimination to large-scale, phishing-driven ransomware campaigns. So choosing to pay a ransom could come with an even heftier price tag in the near future. —Cloud Security Alliance

ICMP Covert Channel for IOS

I wrote a quick-and-dirty covert channel via ICMP for IOS routers.

The channel in question isn't super covert. It's all in plaintext and is quite noisy because it only delivers a single byte of message payload per ping. But it gets messages from routers to the listener via pings, and that was the objective. I expect it to be useful when diagnosing IPSec issues behind unknown overload NATs.

It lives here.

Invoke it on a router like this:

Router#tclsh flash:sender.tcl <target> testing 1 2 3

It will then send 14 pings (13 for the characters in 'testing 1 2 3' plus an <EOM> terminator) to the target machine.

The listener functions as a packet sniffer, so it requires root access. It prints out a line per incoming message, preceded by the sender's IP address:

# /tmp/listener.py 
192.168.5.5 testing 1 2 3


One million broadband offline in Germany; ‘external influence’ blamed

Almost one million Deutsche Telekom customers have been struggling to get online since Sunday afternoon.There's nothing wrong with the network, the company said, advising customers having trouble connecting to the internet to turn their router off and on again in the hope of solving the problem.Around 900,000 lines were initially hit by the connection problem, although the number affected is falling, Deutsche Telekom said Monday. But that number may be an underestimate: Since some of the affected routers also provide subscribers with telephone service, customers may have no way of letting the company know they are having difficulties.The cause of the outage is unknown, with those affected living in different areas and using different routers models, the comapany said. It dismissed suggestions that the problem was worse in congested areas.To read this article in full or to leave a comment, please click here
