“Mendacious machines controlled by hackers that reroute Internet traffic from infected computers to fraudulent Web sites are increasingly being used to launch attacks, according to a paper published this week by researchers with the Georgia Institute of Technology and Google Inc.
The paper estimates roughly 68,000 servers on the Internet are returning malicious Domain Name System results, which means people with compromised computers are sometimes being directed to the wrong Web sites — and often have no idea.
The peer-reviewed paper, which offers one of the broadest measurements yet of the number of rogue DNS servers, was presented at the Internet Society’s Network and Distributed System Security Symposium in San Diego.
The fraud works like this: When a user with an affected computer tries to go to, for example, Google’s Web site, they are redirected to a spoof site loaded with malicious code or to a wall of ads whose profits flow back to the hackers.
The hackers who hijack DNS queries are looking to steal personal information, from e-mail login credentials to credit data, and take over infected machines.
The spoof sites run the gamut. Some are stunningly convincing, others amusingly bogus with spelling errors and typos.”

The FBI called for new legislation that allows the federal police to keep close look at internet activity to track down illegal activities. This seem to go beyond a current plan to monitor traffic on federal-government networks, and that the bureau should have a broad “omnibus” authority to conduct monitoring and surveillance of private-sector networks as well. This could violate the Fourth Amendment’s guarantee of freedom from unreasonable searches and seizures. In general, courts have ruled that police need search warrants to obtain the content of communication

Suspecting a spyware in your system? Here are some tips on how you could get rid of spyware in your computer:
1. Get, install and periodically run Ad-aware and Spybot Search & Destroy.
2. To prevent reinfection by Aureate/Radiate – search for advert.dll on your system. If it’s there and if you can, delete it (Ad-aware will do this for you). Then create an empty text file, name it advert.dll, make it read-only and save it in your Windows/System directory. Then configure Ad-aware (version 5 or later) to ignore advert.dll.

The software giant announced that it will be releasing their own Windows embedded anti-virus that raises some eyebrows in the IT industry. Why, well the company has been known to be the most attacked PC platform on earth compared to other operating systems due to their ways of old. This hatred of the company stems back from the days when Microsoft was involved in what can be called “steal then deal”, when they were involved in getting nifty software form the many start up firms who produced respectable programs they embedded within their OS releases. This is sure to result in lawsuits which the company then opted to settle out of court, buying out the rights and even the company in a hostile take-over. Please tell me more! »

The world of cyber-crime has grown so much in these past few years due to the explosion of growth with respect to the number of internet users the world over. It has not only expanded on the side of normal people but on the side of cyber-criminals who now operate on their own networks, spanning the globe and ready to spread their products, malicious code that first scans the globe for weak points in the security net that we all put up to somewhat give us a sense of security from the ever-growing threat which is actually futile to some extent. Please tell me more! »

A spyware is computer software that is classified as privacy-invasive. This is installed covertly on a personal computer. Once installed, it can monitor the user’s behavior, collect personal information like surfing habits and sites that visited. It can interfere with user control of the computer such as installing additional software, redirecting Web browser activity, accessing websites blindly that will cause more harmful viruses, or diverting advertising revenue to a third party. It can change computer settings, resulting in slow connection speeds, different home pages, and loss of Internet or other programs.
