What’s wrong with Twitter?
Posted by Mourad Ben Lakhoua in Cybercrime & Hacking, Internet, News, Social Networking, Web Security on August 9, 2009
On the 6th of August Twitter went down for a pretty long period. After a while a brief message was added on the Twitter status says they’re fighting off a DDOS attack right now. Well the most interesting that the distributed denial-of-service attack also affected Facebook, LiveJournal and Google’s Blogger.
The idea of distributed denial-of-service (DDoS) attack on the sites is that computers have been compromised by a viruses or other malware and instructed by the Hacker to visit the specific Web sites all at the same time and repeatedly. The barrage of connection requests overwhelms the target sites, making it so that legitimate Web traffic can’t get through.
So this attack requires tens of thousands of machines in which all forms a botnet and in a few seconds can turn any website dawn, as the case of (Finjan report “Your PC might be traded online– without you knowing about it!”).
To secure yourself from being a part of a botnet network is to install an antivirus with the latest signature and in some time check the netstat command on windows to see if there is any unusual connection with your pc.

McAfee AV Patch Leaves Some Computers Unbootable
Posted by Mourad Ben Lakhoua in News on June 10, 2009
Oopsy-daisy! According to complaints on McAfee’s message board, a mandatory service pack for the company’s antivirus VSE 8.7 software has left some machines unbootable. The update, which was issued on May 27 and later pulled on June 2, was intended to squash minor security bugs, but also inadvertently flagged some Windows system files as malware.
“McAfee removed Patch 1 for McAfee VirusScan Enterprise 8.7i from its download servers out of precaution after a potential issue with the update was discovered,” McAfee said in a statement. “A very small number of customers reported trouble with the patch on a limited number of computers.”
McAfee went on to say that it’s working on identifying the cause of the false positives and, once resolved, will repost the mandatory update.
This case shows clearly that It is always recommended to read the instruction carefully before applying any patches and also search information about these updates from a third party like CERT’s in the world because they usually test any updating package and provides some information about the impact.
