    Risks of File-Sharing Technology

    File-sharing technology is a popular way for users to exchange, or "share," files. However, using this technology makes you susceptible to risks such as infection, attack, or exposure of personal information.
    As cell phones and PDAs become more technologically advanced, attackers are finding new ways to target victims. By using text messaging or email, an attacker could lure you to a malicious site or convince you to install malicious code on your portable device.
    Actually, the issue is not that cybersecurity extends beyond computers; it is that computers extend beyond traditional laptops and desktops. Many electronic devices are computers—from cell phones and PDAs to video games and car navigation systems. While computers provide increased features and functionality, they also introduce new risks. Attackers may be able to take advantage of these technological advancements to target devices previously considered "safe." For example, an attacker may be able to infect your cell phone with a virus, steal your phone or wireless service, or access the records on your PDA. Not only do these activities have implications for your personal information, but they could also have serious consequences if you store corporate information on the device.

    Securing Wireless Networks

    Wireless networks are becoming increasingly popular, but they introduce additional security risks. If you have a wireless network, make sure to take appropriate precautions to protect your information.
    Online trading can be an easy, cost-effective way to manage investments. However, online investors are often targets of scams, so take precautions to ensure that you do not become a victim.
    Do not give sensitive information to anyone unless you are sure that they are indeed who they claim to be and that they should have access to the information

    Recognizing and Avoiding Spyware

    Because of its popularity, the internet has become an ideal target for advertising. As a result, spyware, or adware, has become increasingly prevalent. When troubleshooting problems with your computer, you may discover that the source of the problem is spyware software that has been installed on your machine without your knowledge.
    You can be a victim of identity theft even if you never use a computer. Malicious people may be able to obtain personal information (such as credit card numbers, phone numbers, account numbers, and addresses) by stealing your wallet, overhearing a phone conversation, rummaging through your trash (a practice known as dumpster diving), or picking up a receipt at a restaurant that has your account number on it. If a thief has enough information, he or she may be able to impersonate you to purchase items, open new accounts, or apply for loans.
    A rootkit is a piece of software that can be installed and hidden on your computer without your knowledge. It may be included in a larger software package or installed by an attacker who has been able to take advantage of a vulnerability on your computer or has convinced you to download it (see Avoiding Social Engineering and Phishing Attacks for more information). Rootkits are not necessarily malicious, but they may hide malicious activities. Attackers may be able to access information, monitor your actions, modify programs, or perform other functions on your computer without being detected.
    An attacker may be able to insert malicious code into any file, including common file types that you would normally consider safe. These files may include documents created with word processing software, spreadsheets, or image files. After corrupting the file, an attacker may distribute it through email or post it to a web site. Depending on the type of malicious code, you may infect your computer by just opening the file.
