ScanNow for UPnP
Scan your network for particular UPnP security flaws

ScanNow for UPnP is a simple tool which will check your network for devices with newly discovered vulnerabilities in their Universal Plug and Play implementation. UPnP is commonly found on routers, network printers, network-attached storage and many other devices, and if a vulnerable device is accessible over the internet (and security firm Rapid7 say they've found 40-50 million which are) then this could be exposing users "to remote attacks that could result in the theft of sensitive information".

The ScanNow tool itself is straightforward to use. There's no installation required, just launch the download, specify the IP range you'd like to scan (the program will detect and provide sensible defaults for you) and then wait until the process is complete.

When it's done, a report lists everything it's discovered. Check the "Identified" figure to make sure that ScanNow has detected more or less the number of devices you'd expect, and the "Exploitable" figure will let you know if any of your systems are vulnerable.

If you find you've an affected device, don't panic just yet: this isn't in itself a disaster. If the system can't be accessed from outside of your network, for instance, then hackers won't be able to exploit it.

To be safe, though, you should probably still check your documentation to see how you can disable Universal Plug and Play, if you can do without it. Exactly how to do this will vary depending on your hardware, but on the Billion router next to our test PC, for instance, we'd click Configuration > Advanced > Device Management and set "UPnP" to "Disable".


ScanNow for UPnP is a simple and straightforward UPnP vulnerability checker (although figuring out what to do with its results may require some thought)

Requires Java 1.6, doesn't work with Java 1.7...

Posted by: Daniel Donner, 30 January 2013 21:53

You got to be kidding me, a security product that requires Java?
The perpetual vulnerability machine that almost puts Flash to shame?

Another thing, I just had to try since the installer asks for Java 1.6.
It doesn't work with Java 1.7. *Facepalm* reply:

Hi Daniel, according to the developers "ScanNow works fine with Java 7, but the message it displays is outdated"

WhatsApp Messenger 2.12.12

Free Full Commercial Software

WhatsApp Messenger is the world's most popular instant messaging app for smartphones.

You can use it to send and receive text and voice messages, photos, videos, even call your friends in other countries, and because it uses your phone's internet connection it might not cost you anything at all (depending on whether you'll pay data charges).

It's easy to set up and use. There's no need to create and remember new account names or pins because it works with your phone number, and uses your regular address book to find and connect you with friends who use WhatsApp already.

You can talk one-to-one or in group chats, and because you're always logged in there's no way to miss messages. Even if your phone is turned off, WhatsApp will save your messages and display them as soon as you're back online.

There's plenty more (location sharing, contact exchange, message broadcasting) and the app is free for a year, currently $0.99/ year afterwards.

Version 2.12.12 brings:

• Links that you share or receive will now include a rich preview. When sending a link, you have the option to not include a rich preview.
• Additional 3D Touch features: You can now quickly Peek and Pop chats.
• Redesigned Settings tab. 
• You can now view all your starred messages across all your chats in Settings — Starred Messages.
