Researchers Hack GSM phones.

Researchers have shown a simple technique for eavesdropping on individual GSM mobile calls without the need to use expensive, specialized equipment. This kind of GSM snooping has been possible for a long time, but it’s always been very expensive.
During a session at the Chaos Computer Club Congress (CCC) in Berlin, Karsten Nohl and Sylvain Munaut used cheap Motorola handsets running a replacement firmware based on open source code to intercept data coming from a network base station.

Google's new feature: Hacked site alert.

Google has added a new feature to it's search engine. It can alert the users in its search result for websites that might have been compromised by displaying the link - 'This site may be compromised'. When users click the new "This site may be compromised" link, they get directed to more information in the Help Center. The websites flagged as compromised are still accessible.
It's a great idea to alert the naive users from being affected by malware & spyware & avoid affecting other users. Google plans to alert the hacked site's webmaster, as well, Wald said. The search engine giant already provides a notification in search results for sites that are potentially serving up malware.

CONFICKER Worm : What is it anyways?

Conficker, formally named W32/Conficker.worm, also known as Downup, Downadup and Kido. It uses flaws in Windows software and Dictionary attacks on administrator passwords to co-opt machines and link them into a virtual computer that can be commanded remotely by its authors. Conficker has spread rapidly into what is now believed to be the largest computer worm infection since the 2003. Researchers have found 5 variants of conflickers - Conficker.A, Conficker.B, Conficker.C, Conficker.D & Conficker.E.

Implementing & Preventing SQL Injection Attacks Tutorial -2

In the previous post, we have seen a basic sql attack structure. In this site, we will understand - how to find sql attack vulnerable site. To find SQL vulnerable sites, we can use google. We search for a specific strings in google to get sites which are revealing some information about the site. Such strings are called 'Google Dorks'.

Stuxnet - The standard malware, if not unusually sophisticated!

Symantec has issued a dossier on Stuxnet depicting ins-outs of the malware, who were the targets & what was the objective.
According to Symantec, Stuxnet targets specific frequency converter drives ( only frequency drives from two companies that are running at high speeds – between 807Hz and 1210Hz.) — power supplies that are used to control the speed of a device, such as a motor. The malware intercepts commands sent to the drives from the Siemens SCADA software, and replaces them with malicious commands to control the speed of a device, varying it wildly, but intermittently.

Creating Linux environment & installing Linux softwares in Windows!

There are plenty of solutions for achieving linux environment in Windows.
1)Installing Cygwin creates linux environment. But all programs are not supported by cygwin. Also it may create problems in newer versions of windows. It consists of two parts:
  # A DLL (cygwin1.dll) which acts as a Linux API emulation layer providing substantial Linux API functionality.
  #  A collection of tools which provide Linux look and feel.
Problems regarding cygwin
 # Cygwin is not a way to run native linux apps on Windows. You have to rebuild your application from source if you want it to run on Windows.
 # Cygwin is not a way to magically make native Windows apps aware of UNIX  functionality, like signals, ptys, etc. Again, you need to build your apps from source if you want to take advantage of Cygwin functionality
