Zombie computers are those machines that are hacked by spammers with the help of computer virus so that they may be used as a host to send out thousands of spam messages. A study conducted by McAfee earlier this year showed that USA, Brazil and India are among the leading nations when it comes to producing spam. However, the report noted that China, USA and Brazil are countries that host the maximum number of zombie computers. India is nowhere in the top 10.
In a somewhat contrary note, CommTouch has come up with its latest quarterly security report where the researchers have noted that India has just overtaken Brazil as the country with the largest number of zombie computers. According to the report, here are the top ten countries and the percentage of zombie computer that they host.
1. India : 13%
2. Brazil : 11%
3. Vietnam : 6%
4. Germany : 5%
5. Russia : 5%
6. USA : 4%
7. Argentina : 3%
8. China : 3%
9. Saudi Arabia : 3%
10. Italy : 3%
11. Columbia : 2%
12. UK : 2%
13. Argentina : 2%
14. Romania : 2%
15. Poland : 2%
Nigerian scammers are no longer exclusively from Nigeria. Though email phishing attempts are now common-place, the stereotype that such emails originate only from Nigeria has struck. Nevertheless, with people getting aware about the regular phishing emails, these scammers have now been taking the extra mile to fool you.
Check out this extremely hilarious conversation between Brad Carter and “Rebecca Nemanova“. Rebecca apparently lives in Nigeria and wants Brad to courier his laptop to her boss. Over to Brad Carter
A new security flaw has been detected on the older versions of Microsoft Windows Operating system – namely Windows XP and Windows 2000. The vulnerability will allow hackers to exploit the system and subsequently run malicious code.
In a statement released to the media, Microsoft Group Manager Jerry Bryant said that his team was presently investigating the issue. The company has also confirmed that they are unaware of any attempts by hackers to make use of the vulnerability so far.
According to Secunia, the flaw could arise due to a boundary error in a function that was employed on these versions of the Windows operating system. Microsoft has termed the vulnerability “moderately critical“.
AVG Technologies, the popular antivirus solutions company has announced its plans to unveil a new LinkScanner malware detector application for Mac. The application will allow users to check web pages in real-time for malware in the outbound links from any website.
The application is already available on the Windows platform and AVG has revealed that the Mac version of LinkScanner will also be free to download. Explaining the software’s algorithm, the company notes that rather than relying on a database of blacklisted sites to offer an advice to users, LinkScanner will resort to real-time scanning of destination websites to issue an alert to users.
The date of release of the application has not been announced as yet.

Symantec has released an anti-virus application that will offer Android users protection against virus, malware and even unwanted callers. The application is expected to be incorporated natively in Froyo though users may download it earlier that that.
The app shall be free to download and the users are offered 30 days of free service with respect to automatic updates. The service will need subscribers to upgrade to a paid plan after that. The subscription cost is unknown at the moment, though.
Here are some things we’ve learned the new Anti-Virus for Android OS can do
- Scan malware/virus
- Call screener to block unwanted callers
- Remotely lock/wipe in case of theft
That goes much beyond conventional anti-virus softwares, doesn’t it?
A cyberattack at the Penn State University – the third time in six months – has resulted in close to 15,000 social security numbers getting exposed. This comes just two weeks after a similar attack at PSU left close to 9,766 SSNs exposed. According to Geoff Rushton, a spokesperson of PSU, the institution is working with national and regional agencies to investigate the case. The names of these agencies have not been released due to confidentiality agreements.
The exposed individuals are noted to be students at the university prior to 2005. Since 2005, the institution has stopped using SSNs as a personal identifier. While the database of numbers have since then been removed, an archived copy of the same is reported to have remained undetected in the computer cache from where these numbers were exposed.
A similar attack in December last year is reported to have exposed close to 30,000 SSN numbers.

There was a lot of brouhaha last month over reports that Google had been collecting private data transmitted via unsecured wireless networks on the company’s Street View vehicles. While Google confessed that the company had indeed breached on private information, the company said that the data collection occurred unintentionally and there was a software error in the episode.
Following the breach and the negative publicity that followed, Google has now annouced that the company is hiring leading Internet security firm, Stroz Friedberg to look into the software issues that led to the private data to be collected in the first place.
A report is expected by the end of this week.
