- You run some version of Windows (XP, Vista, etc)
- You use a wireless router at home
- If you followed it's instruction manual to set it up. But you don't remember following any instructions in there that had to do with changing your routers password.
- If your friend set it up for you and you are not sure
Zlob is one of the first of it's kind of trojan softwares to modifies a wireless router's settings to achieve it's goal. To date, this technique has only been employed by hackers who have to do this manually. Given a routers manufacturer and model number, Its surprisingly easy to find out a router's default password (here's an example found via a simple Google search).
These days it is getting increasingly difficult to avoid being affected by malwares (short for "malicious softwares"). According to the article above Zlob is one of the most downloaded Trojans today. So here are a few precautions
- Install a Antivirus Software. It's surprisingly common to see people dont know that they NEED to have a antivirus software installed. There are quite a few free ones available. But if you are happy to buy one, it's worth the money (see: Which Antivirus?)
- Install a Firewall Software. A firewall software sits between your computer and network based attacks (see: Which Firewall?)
- Make sure your Antivirus/ Firewall software automatically downloads updates to its detection databases. Remember, a few minutes of inconvenience are far better than days of computer problems!
- Change your router's default password. Instructions on how to do this should be in your routers manual.
- If you've misplaced them, look through the manufacturer's website for instructions
- If nothing, google for it (here's an example)
- And in case you suspect that you're already infected, try asking for help at Bleepingcomputer.com. Not only is it free but they are pretty good at wha they do (kudos guys!).
