Linux for Travelers - Fraud Prevention Tips en Public Web Surfing Article in the New York Times <p>The New York Times ran an article on <a href=";en=dbe69b7dfa41df22&amp;ei=5088">the dangers of using public Internet access</a>.</p> <blockquote><p>While it is hard to say how likely it is that someone is lurking on a public network, many public networks do not have adequate security.</p> <p>Last fall, InfoWorld magazine published an article about a security researcher who managed to collect more than 100 passwords, per stay, at hotels with lax security (about half the hotels she tested).</p> <p>Gathering reliable statistics about security breaches is notoriously difficult, since companies are reluctant to reveal this information. Still, the most recent computer crime and security survey, conducted annually by the Computer Security Institute with the Federal Burea Description of Investigation, found that the average loss from computer security incidents in 2005 was $167,713 per respondent (based on 313 companies and organizations that answered the question).</p> <p>As Jim Louderback, editor of PC Magazine, noted, the statistics may not matter given the problems one data breach can cause.</p></blockquote> <p>The article mostly covers wireless computing.

I belive that the "419" refers to the legal code that is being violated.</p> <p>Some resources and reading to educate yourself about these kinds of email scams:</p> <ul> <li><a href="">419 education page</a></li> <li><a href="">News from the BBC on 419ers</a></li> <li><a href="">More 419 news from BBC</a></li> <li><a href=""></a></li> </ul> <p>I recieved the following scambaiting email today and wanted to post it as an example:</p> <blockquote><p> ATTN:</p> <p>My name is Barrister Anderson Mako I am a private attorney . and I have a client who is interested in investing some good money in your country.</p> <p> My client is a very important and prominent person who has mandated me to contact you for a very important business transaction my client is by name Mrs. Maryam Abacha and she is the wife of a Late Military head of state in one of the richest african country.</p> <p>Her husband Late General Sanni Abacha made a lot of money through Oil proceeds during his tenure in office.

If a computer has a hardware keylogger on it, it will be able to record your keystrokes even if you are using a Linux live CD.</p> <p>There is a solution though. While using an <a href="">on-screen keyboard</a> will not protect you against software keyloggers, an on-screen keyboard should protect you against hardware keyloggers. So the combination of a Linux live CD and the use of an on-screen keyboard to enter your passwords should protect against both hardware keyloggers and software keyloggers.</p> <h2>The Risk of Hardware Keyloggers in Public Internet Cafes</h2> <p>I suspect that hardware keyloggers are not common in public Internet cafes. It is much easier for Internet criminals to use malicious software to do their work for them remotely. Physical devices attached to the computer increase their chances of getting caught.</p> <p>While most public computers have spyware, viruses, and trojans, very few have hardware keyloggers. In any case, here are some tips:</p> <h2>What Do Hardware Keyloggers Look Like?</h2> <p>I've linked to some images of hardware keyloggers below. The most common hardware-based keyloggers are a physical device that fits between the end of the plug of the keyboard and the box of the computer:</p> <ul> <li><a href="" rel="nofollow">A hardware keylogger that fits between keyboard and computer</a></li> <li><a href="" rel="nofollow">A hardware keylogger for USB keyboards</a></li> <li>A <a href="" rel="nofollow">before</a> and <a href="" rel="nofollow">after</a> shot of a computer with hardware keylogger installed. Notice the extra length of cable in the &quot;after&quot; image.</li> <li><a href="" rel="nofollow">Another hardware keylogger</a></li> </ul> <h2>Hardware Keylogger Lookalikes</h2> <p>Be aware that not every device that fits between a keyboard and a computer is a keylogger. There are <a href="">similar-looking devices</a> that are made to convert one type of plug to another (for example USB to PS/2). These adapter plugs are harmless.</p> <h2>How to Protect Yourself Against Hardware Keyloggers</h2> <p>It's always good to take a moment to look at the connection between the keyboard and the computer before you use a public computer. That is not the only kind of hardware keylogger though. There are also hardware keyloggers that can be put inside keyboards, or in other hard-to-detect places. By using a Linux live CD in combination with an <a href="">on-screen keyboard</a>, you should be able to bypass hardware keyloggers.</p> <p><a href="">read more</a></p> Fraud Prevention Tips Keyloggers Windows Security Linux Security Thu, 10 Aug 2006 23:25:10 -0400 LFT 99 at Phishing <p>I mentioned <a href="">phishing</a> recently. I just got a phishing attempt in one of my email accounts so I have a good example to show.</p> <p>The following email looks like it might be from eBay, but it is from an Internet criminal. The links in phishing emails usually lead to fake web sites where you are tricked into giving your credit card or other financial information. Notice how the email describes how you will need to update your credit card information. </p> <p>Because this email is addressed to "eBay user" and not my real name, I know it is probably fake. Another clue that it is fake is that I don't have an eBay account. If I couldn't determine whether it were real or not, I would open a browser and type in <tt></tt> and login on the actual eBay site. Never click on links in these kinds of emails.</p> <p><img src="" alt="eBay phishing attempt" style="border: 1px solid #333;" /></p> <p><a href="">read more</a></p> Fraud Prevention Tips Identity Theft Phishing Tue, 01 Aug 2006 19:55:07 -0400 LFT 98 at Phishers Bypass Two-Factor Authentication <p><a href="">Phishing</a> is a common form in Internet fraud, where criminals send you an email (for example) that pretends to be from a bank, PayPal, eBay,, or another web site. The emails often say things like, &quot;Your password has been compromised. Please click here to login and update your password.&quot;</p> <p>If you click on the link you are taken to a fake web site that looks just like the real thing. The criminals hope that you will enter your password and credit card information into their fake web site.</p> <p>In a twist on the common form of phishing, <a href="">a scam has been spotted</a> where the criminal's web site asks you to type in your <a href="">two-factor authentication</a> code (<a href="">example</a>) and it automatically logs into your bank account with your credentials.</p> <p><a href="">read more</a></p> Fraud Prevention Tips Identity Theft Phishing Sat, 15 Jul 2006 23:01:24 -0400 LFT 89 at Browser Security <p>If you are using the Windows operating system, try to use the <a href="">Firefox Browser</a> because it is more secure.
