What are Backdoors and Wrappers? Tips to Protect Yourself Posted: 13 Jan 2012 06:59 PM PST Guest post by Greg Salter. Backdoor – A Backdoor is a program or set of related programs that are installed on your system by the hackers so that they can access your system for later use. The technique is simple but very efficient. The “goal” of a Backdoor is to remove the evidence (in form of log files) of initial entry in the system. The Backdoor allows Hacker to gain access to the computer and penetrate even if it was detected or remediated by the system. Wrappers – How do you think a hacker install a virus, worm or Trojan on the victim's computer? Answer to this question is Wrappers, these are software packages which are used to conceal and deliver a virus, worm or Trojan. Wrappers wrap a legitimate file with virus, worm or Trojan. Both the legitimate file and the Trojan file are combined into a single executable file and then that file is installed when the legitimate program runs. Generally, games and animations are used as wrappers to install virus files. In this way, users will not get suspicious but only see the program being installed. Some indications of a virus infection: The programs take a long time to load. The hard disk is always full even without installing any software. The hard disk runs when not in use. Remained unknown files appear in the system. The keypad emits strange sounds. The monitor displays strange images. Programs act erratically. The names of the files become strangers. The hard drive becomes inaccessible. The size of the program is constantly changing. Some indications of a Trojan infection: The CD-ROM opens and closes by itself. The background wallpaper settings change. Documents or messages print on the printer by own. The browser you use, look strange or open unknown websites. The window colors settings change on their own. The mouse functions are exchanged. The mouse pointer disappears. The person who is chatting with you know too much about you and your computer. The computer turns off by itself. The account password has been changed. Foreign purchases appear on your credit card bill. Prevention is your protection: Install anti-virus software and keep it updated regularly. Do not accept or install disks or programs without checking by the latest version of anti-virus. Do not leave discs in the CD-ROM longer than necessary. Do not download anything from the Internet if you are not 100% sure about the website you are visiting. Although the program or file comes from a friend, make sure about the file before opening it. Use multiple virus scanner. Install software to identify and remove adware (malicious advertising), malware and spyware. And keep your OS updated. © 2011 TipsBlogger.com | Home | Contact | Submit Guest Post |
