A - Z ( hacking & Computer related Terms ) Part 8 Trojan – A Trojan, or Trojan Horse, is a malicious program disguised to look like a valid program, making it difficult to distinguish from programs that are supposed to be there. Once introduced, a Trojan can destroy files, alter information, steal passwords or other information, or fulfill any other sinister purpose it was designed to accomplish. Or it may stay dormant, waiting for a cracker to access it remotely and take control of the system. A Trojan is a lot like a virus, but without the ability to replicate. Virus - A virus is a malicious program or code that attaches itself to another program file and can replicate itself and thereby infect other systems. Just like the flu virus, it can spread from one system to another when the infected program is used by another system. The more interconnected the host is, the better its chances to spread. The spread of a virus can easily occur on networked systems, or it could even be passed along on other media like a CD or memory stick when a user unwittingly copies an infected file and introduces it to a new system. A virus could even be emailed with an attachment. “Virus” is often incorrectly used as a catch-all phrase for other malicious programs that don’t have the ability to self-replicate, like spyware and adware. Wardriving – Wardriving is the act of driving around in a vehicle with the purpose of finding an open, unsecured Wi-Fi wireless network. Many times, the range of a wireless network will exceed the perimeter of a building and create zones in public places that can be exploited to gain entry to the network. Black hats, and even gray hats, will often use a GPS system to make maps of exploitable zones so they can be used at a later time or passed on to others. Wardriving is not the only way this task is performed – there are Warbikers and Warwalkers too. As you can see, it is imperative that your WiFi network is secure because there are entities out there looking for any opening to ply their trade. White Hat – While black hats use their skill for malicious purposes, white hats are ethical hackers. They use their knowledge and skill to thwart the black hats and secure the integrity of computer systems or networks. If a black hat decides to target you, it’s a great thing to have a white hat around. But if you don’t, you can always call on one of ours at Global Digital Forensics. Cyberlove
