Remove Netsky and Sasser worms

February 19, 2016

There are no safe computer systems in the world because no matter how sophisticated they are, they’re still made by human beings and thus they are bound to be broken one way or another.  Even the most heavily guarded computers and corporate and public servers are still prone to being infected by malware and millions of malware attacks target these servers on a daily basis.  Once the authors of these malware get in and gain access to classified files of these corporate and government servers and sell these to people who wants to sow disorder, there’s no telling what could happen next. These malware bring so much damage and it also costs a lot of money to remove malware.

One of the malware that wreaked havoc on a global scale is the Sasser and Netsky worms which was written by a then 17-year old German student, Sven Jaschan. This was first detected on February 16, 2004 and within minutes infected hundreds of computer systems and after 48 hours it has spread to millions of servers, desktops, and laptops. According to Sophos, these worms accounted for 70% of all the malware that were live and circulating during that time. The worms took advantage of a security flaw in the Windows environment and spread through email and IP address spoofing. Once inside these computers, these worms will overwrite important system files and gather important data and uploads them to a server.  This kind of malware behavior will give the author access to very sensitive data.  To remove  Sasser and Netsky worms, it was estimated that the US alone spent billions of dollars for that task not to mention the cost that the virus incurred due to the important services that it disabled.

It took quite a while to totally remove Sasser and Netsky worms from infected systems as these malware was intricately written. The author of those two worms, Sven Jaschan, by sheer luck avoided spending time in prison because he was still underage when he released them.  He was sentenced to two years of probation and 30 hours of community service on a nursing home. After those attacks, Microsoft beefed up the security of their operating systems.

Antivirus, Antispyware, antimalware apps are man-made and thus prone to have imperfections so even if no security software is completely and totally attack proof, it is still better to install one on your computer rather than having installed none at all.  Better be safe than sorry.
