However, the trend is quite popular in Vietnam and other Asian countries on account of high prices for fast connections.
With the spreading of broadband Internet in homes at affordable price range, the trend of cybercafés has almost diminished in the western countries after late 90's. As per the figures given by BKIS, nearly 45,000 computers across Vietnam have been discovered with this virus. It has been found that online shops solely depends on the abovementioned software and do not have other protections installed fall to. Interestingly, the worm does not leave any scope for its identification by frozen system programs such as Deep Freeze while writing on hard disk.Īfter entering the system undetected, performs a number of malicious operations from the infected system - such as seizing online game passwords, displaying fake gateways, automatic upgradation of new variants and insertion of iframe exploiting application that circulate through USB and LAN. However, utilizes a new technique in which it directly writes on sectors of hard disk by requesting for direct link with the disk controller. Hence, online shops often believe that their systems are safe from virus attacks as they have installed Deep Freeze application. As the system initiates the rebooting process, temporary data saved in the buffer gets deleted and the system is restored to its previous state. When a normal program retrieves anyone of these sectors, it collects data from the buffer sector instead of the original sectors. Faronics has developed Deep Freeze application to facilitate administrators to restore their systems after being used by unauthorized parties.Ĭybercafés, school computer labs and libraries are increasingly using this application to protect their systems from hackers' attacks.ĭeep Freeze prime function is to monitor changes in sectors (like data storage area) within hard disk partitions and save changes in another area (like buffer). The worm was first detected in early March 2009, and since then, around 174 new variants of this Chinese born virus have been discovered on the Internet. Security researchers at Bach Khoa International Security (BKIS) have warned computer users about a new worm called that has an ability to bypass security applications such as Deep Freeze. BKIS – Deep Freeze Application Fails to Detect New Chinese Worm Hence, online shops often believe that their systems are safe from virus attacks as they have installed Deep Freeze application.
