No Linux or Mac drivers for Skype phones? What are they thinking?

and only half a page (not even half a page) of news on the 3skypephone on google. Soon more about the google phone ? Very few review also to be seen.... I have never seen so little viral marketing and hype when it came down to skype. The air is out of the bubble it seems... A little bit more can be read on the blogs, but the whole 3skypephone buzz feels like a storm in a glass...

Here some reviews on the 3skypephone. Have not seen one myself. We'll see, maybe I'll be able to say something else when it can be touched.

Will the current Skypeworms also affect the 3 skype phones ?

Skype_worm No clue on the above, of course with all those things attached to Skype, it's no wonder it's virtually impossible to protect yourself (or your users) from all kinds of potential crap.

Time will tell. But do read this new Skype worm popping up : "It has come to our attention that some Skype for Windows users have been affected by a piece of malware that masquerades as a chat message aimed at finding a lost girl.Please do not follow any internet links you may receive in chat messages that resemble the following: “Please help me to find this Girl”. Clicking on the link will lead you to download a worm that is currently best described here." source.

harnessing zombie PCs and spewing spam across the Web

Skype_worm Seriously. VoIP/IM based systems will be on the chopblock. It's time for Skype to really secure their systems..  In analogy : "Storm worm offers trick, no treat The Storm worm, which is harnessing zombie PCs and spewing spam across the Web, is estimated to have a computed strength varying from 15 to 50 million PCs. There's special reason to watch out for e-mail that arrives in your inbox: Storm worms have been reported to be behind the surfeit of spam mail inviting users to download content specific to Halloween. Is your organization equipped to handle a mass-scale attack from a network of a million PCs?"  source.

Single Point of Control for IM, P2P, Spyware and URL Filtering

I missed this web-conference. But it's right on the topic: "Your employees - especially the Web 2.0 generation - often introduce consumer-oriented applications onto the corporate network to work more efficiently. When these applications circumvent the security infrastructure, it's difficult for IT to maintain visibility and control. How can your organization take advantage of the productivity and cost benefits of real-time communications while mitigating their inherent business risks?

Discussion of connectivity and convergence

"Much of the discussion of connectivity and convergence almost reflexively uses the total amount of bandwidth available as the key metric. While it certainly is a vital statistic, a far lower profile set of metrics is just as important in determining how well a convergence application such as video streaming or VoIP performs. The most common of these statistics - jitter and latency - deal with the timeliness and predictability with which data packets get to their destination. If these metrics are askew, convergence applications will perform poorly no matter how much bandwidth is thrown at them. We found a good primer at Smart Communications on four important topics concerning non-bandwidth elements that can threaten a converged application." source.

Skype’s cooperation with internet censorship in China

I noticed something simular earlier this year I think on tom.com (meaning a special version of Skype by tom.com with a content-filter) when downloading http://skype.tom.com . So the below is not really new information, but just probably a revelation for some of us. Basically Skype is just a company here that provides a special version of Skype for the Chinese territory. That is how I see it. I know that there is a list in China with the forbidden words, and since they are forbidden nobody talks about them … Censorship in China, we all know it exists. Basically don't do funny things.. Here is the news-line.

" Dynamic Internet Technology Inc. Alleges Skype Redirects Users in China to Censorware Version - Ten Days After Users Are Able To Download Freegate Software Through Skype CARY, N.C.--(BUSINESS WIRE)--DIT alleges discovery of Skype's cooperation with internet censorship in China, which DIT believes is an effort to stop the spread of DIT's popular anti-censorship tool.

Skype (http://www.skype.com), an instant messaging, voice chat and file downloading tool, is very popular in China. On September 13, 2007, DIT established its presence on Skype, so users in China can talk to DIT over Skype to get DynaWeb url and download its popular censorship-busting software, Freegate.

DIT alleges that, on the morning of September 23, the company started to receive reports from concerned users in China that now when they try to download the Skype software, Skype's website redirects them to Skype's Chinese partner's site, http://skype.tom.com, which doles out a modified Chinese version, instead of Skype's official version as before.

DIT feels that such a version of Skype from a Chinese website is questionable, as some hidden capabilities can be built-in to censor Skype's usage. In January, 2006, Business Week reported that "TOM and Skype now filter phrases such as "Falun Gong" and "Dalai Lama." According to DIT, internet freedom activists in China have been warning people about the possibility that Tom.com's versions have or will have more trojan capability to monitor and report users' activities to Chinese government.

DIT has confirmed this redirection. DIT believes this move by Skype is the result of Chinese government's pressure, targeting to curb Freegate's wildfire-speed adoption in China.

Freegate is part of DynaWeb technologies. DynaWeb enable users to evade Internet censorship and to visit websites that are otherwise blocked. DynaWeb was first launched in March, 2002. It is developed and maintained by volunteers and personal contributions, and has enjoyed great popularity among users in China and Iran, despite Internet restrictions by the governments in these countries."

Skype v3.5 management and blocking capabilities

This one is all about blocking p2p, Skype.

" REDWOOD CITY, Calif.--(BUSINESS WIRE)--Check Point Software Technologies Ltd. (NASDAQ:CHKP), the worldwide leader in securing the Internet, today announced that its enterprise security gateways now have the unique ability to block Skype v3.5, the latest version of the popular consumer VoIP application. This development, leveraging Check Point's SmartDefense™ integrated intrusion prevention capabilities, is part of the company's ongoing efforts to help enterprises better manage the risks from consumer software downloaded by employees for personal use.

The addition of Skype v3.5 management and blocking capabilities is particularly critical because a new virus called "w32/Ramex.A" is currently spreading through Skype for Windows. Infected users send a chat message to other Skype users, asking them to click on a web link that can infect the computer of the recipient. With Check Point, an IT administrator could immediately secure the corporate network against the virus by simply blocking Skype use until the virus storm has passed, or limiting use to versions not affected.

Consumer applications such as instant messaging (IM), peer-to-peer (P2P) file sharing and Skype are often installed by employees without the company's knowledge or consent. Once installed on even a single PC connected to the network, the application can become an open avenue for hackers seeking to infiltrate the network. Check Point has strategically developed extensive security and management features for IM and P2P applications running across a corporate network. By offering IT administrators more granular control of these applications, an enterprise can reduce the risk of security breaches associated with consumer software vulnerabilities as well improve employee productivity by limiting distractions.

"IM, Skype and P2P applications are exciting new ways to communicate and collaborate, but enterprises must have control over anything with the potential to introduce new threats into the network," said Dave Burton, director of product marketing at Check Point. "Check Point is leading the way by ensuring that these management and blocking capabilities extend to the most current versions of consumer software applications, such as Skype v3.5."

Beyond security vulnerabilities, the potential for proprietary information to be sent off the network without approval introduces legal and competitive risks. Plus, the added bandwidth consumption from these products can increase IT costs and negatively affect the performance of the overall network. Lastly, employers may not want employees to be distracted by alternative communication mediums such as Skype, MSN, Jabber, ICQ and others.

As part of Check Point's management capabilities, IT administrators can limit or entirely block IM and P2P communications, and help set boundaries over their network traffic. Real-time updates from Check Point's SmartDefense Services provide Check Point users with the latest patches to ensure customers are protected against new exploits, vulnerabilities and protocols. Additionally, the Check Point SmartDefense engine allows administrators to add advanced functionalities that are both protocol- and heuristic-based.

For more information on how to protect against IM and P2P applications that pose a threat to enterprise security, please visit www.checkpoint.com. "

Telework Security Concerns Linger

 

" While managers are growing more comfortable with remote workers, three areas of concern remain. Managers worry about how productive the workers will be while outside the office; how their absence will impact team building; and, of course, how their data will be secured. The SonicWall survey that led to these conclusions also points to shortcomings in preparedness. For instance, only 23 percent of off-site workers have anti-virus software on their machines, only 16 percent have SSL VPNs and only 14 percent have IPSec VPNs. A startling 9 percent of those charged with security don't know what measures are in place for their remote staffs. The survey offered comparable anemic statistics for the related area of disaster preparedness. " source : IT Business Edge

Variant of the Skype Bubbles worm.

FaceTime Security Labs (FSL) has identified a variant of the Bubbles worm on Skype. The team at FSL found what they're calling "Bubbles for Kids" that is designed to steal any and all sensitive information from the victim's computer through the most devious method of all...keylogging! It looks like it not only attempts to steal all your info on your machine, but once it's done that, it spreads out to all your Skype contacs. The team have written up their find on the Spyware blog - which you can find here. It's probably a good time to remind you that FaceTime's Internet Security Edition for Skype, is not only a great solution, but it's unique and its backed by the great work - like this discovery - that the FaceTime Security Labs do in discovering new threats over real-time communications channels.

So basically for all those happy people out there, better get some proper security before you "skypetize your ms office documents…" Get real !

Skype worm, related to keylogging and potential data theft.

Something to keep in mind for all those happy people that might simply be adding things like Skylook to their MS outlook or the new Skype MS office integration toolbar. Think twice before you simply Skypify your MS office documents !

I wish Skype would come out with a Business Control Panel application that allow IT-managers to run their cloud of internal Skype network users. One thing that this application would have to provide is an overview to the number of Skype extra's that are attached to the Skype-users their application.

My personal opinion is that if you start simply linking MS office document via Skype plugin to Skype, well you are looking for trouble. Until it is exactly clear and documented what that exactly means, I would recommend to use it wisely.

In the past I was very happy with Skylook, but I am convinced that for those Exchange server admins, it will pose some concerns. You simply don't attach things that suck up company content (and send it to god knows where...) to your office-mail system. I have documented the risk of Skylook earlier. It's the same with plugins like Plaxo and Linkedin. I would not recommend to simply add them to your MS outlook system. You can do it, but I have never seen an IT-manager smile when this happened en masse in their network. It should not just be happening without any notification. Until then the IT- and security guys will fight the Web 2.0. movement, since they perceive it as an attack and something unmanageable.

Make sure your data doesn't walk out the door

" Hacker attacks that bring down the network get a lot of attention, so companies concern themselves with protecting against those threats. Unfortunately, the security precautions that prevent those high-profile attacks may not be addressing a much more insidious problem: theft of company data for corporate espionage or other purposes. Find out what you should be doing to keep your data from walking out the door." Source : Network Administration at TechRepublic.com [newsletters at www.techrepublic.online.com]

Bad p2p habits ? Should we apart from getting more used to p2p also get a bit more worried ?

Should IT Worry About P2P's Traffic Domination? Yes

" P2P may not have been the culprit in the Skype blankout, but peer sharing is still bad news for network admins. A research firm says P2P accounts for 50 percent to 90 percent of the traffic on the Internet. Some observers say small companies' reliance on P2P is unfortunate because it means that there is little oversight. Clearly, companies of all sizes should do whatever they can to squelch their employees' bad P2P habits. "

My take : use it wisely and invest in security.

P2P identity theft leads to 29 years jailtime.

P2p_ticking_timebomb_2 " A Seattle man faces as many as 29 years in prison after being charged with using the LimeWire and Soulseek p-to-p (peer-to-peer) networks to commit identity theft. Gregory Kopiloff was arrested Wednesday on charges of mail fraud, accessing a protected computer without authorization, and two counts of aggravated identity theft, said Emily Langlie, a spokeswoman with the U.S. Attorney's Office for the Western District of Washington. This is the first case that Langlie's office is aware of that involves P-to-P identity-theft charges, she said." source.

Skype is now being used as a 256 AES encrypted delivery mechanism for sound, files, voice and yes also the occasional worm / virus.

I wonder what caused the problem this time and what explanation we are going to make on the matter of Skype PR this time.

It seems to me that me somebody just set off something that exploits weaknesses in the whole Skype p2p system. I have always said (apart from it greatness in transmitting sound and video over p2p) that this would happen and it looks like it's happening now.

Employees Drive Adoption of Instant Messaging, Skype and Unified Communications in the Enterprise

FaceTime® first to deliver security, management and compliance for Web browsing, instant messaging and UC applications under a single point of control

FOSTER CITY, Calif., Sept. 10, 2007 – Responding to the changing nature of Internet traffic, FaceTime Communications today announced the first network security appliance that provides comprehensive security and management across the broadest set of Web and real-time communications applications under a single point of control.  The Unified Security Gateway (USG) integrates management, security and compliance for Web communications, consumer-driven greynet applications such as public instant messaging (IM), Skype and P2P, and enterprise-class unified communications platforms such as Microsoft’s Office Communications Server and IBM Lotus Sametime.

The New Internet
Internet communications have changed. Today, user-initiated traffic is no longer limited to e-mail and Web browsing, but dominated by highly evasive greynets – real time communications such as IM, Skype, P2P and hundreds of other unique applications and networks. Today’s workforce is introducing these consumer networks into the enterprise to improve communications at work and to stay connected with their extended social networks.

Responding to this end-user demand, many large organizations are deploying enterprise-grade Unified Communications platforms such as Microsoft Office Communications Server and IBM Lotus Sametime.

“IM has become the launch pad from which other forms of communication or meetings are established – a Web conference or voice over IP call for example,” said David Mario Smith, research analyst for Gartner, Inc.. “The consumer IM client has become a UC client, and organizations are rapidly adopting enterprise IM and UC platforms. Today, we’re seeing a 25 percent to 30 percent penetration of enterprise IM, and we expect to see nearly 100 percent by 2010.”

According to prelimina
