Wildfire

Saturday, January 2nd, 2010

No, we’re not talking about the wildfires in the western part of the U.S., or not even something that can harm your computer.

Some times you will get an E-mail with a virus warning like the one that recently circulated on the web about the “A Card for You” virus.

Without checking to see if the virus is real, many people immediately forwarded the note to everyone they know, and urged them to do the same. Many of them did so, and false information spread like wildfire around the web. This particular virus was exposed as a HOAX. If anyone had bothered to take the time and do a search on “A Card for You”, they would have found the web page at Symantec which clearly reports it as a HOAX.

The only thing you are accomplishing is to frighten people and cause unnecessary concern. In point of fact, you could unwittingly cause problems for the people you send them to, like the SULFNBK.EXE Warning did. This hoax urged people to search for the “sulfnbk.exe” file on their computer, and if it was found to delete it. Sulfnbk.exe, is a valid Microsoft Windows 95/98/Me utility that is used to restore long file names, and if you use any of these Windows systems, you will find it. This caused a lot of people to delete it, and then they had to scramble to restore it.

I recently received an E-mail outlining a persons experiences with viruses, and he urged everyone not to accept any E-mails with an attachment. He has set his mail reading program to automatically delete any message with an attachment. This is an over reaction. One of the advantages of the web is the wealth of information available on the net.

Much of the information available includes files that are too large to read as E-mail, and are automatically converted to a file. These are text files and cannot hurt you, and neither can an image file.

I will not accept an .exe file, a .doc file or a .zip file and neither should you… UNLESS it is from a reputable, known source and you have specifically requested this information.

We, for example, have the Eudora software available at our Web Site and are authorized distributors. I personally have used this program without problem for quite some time, and the same software I use is available there. Does this mean you should accept unsolicited files from friends – NO! They could unwittingly be infected and could pass the virus along to you.

Blocking all attachments is not realistic. The maxim you should follow is simple – don’t download files unless you have requested them – but let’s face it, if you receive an unsolicited attachment, be wary but don’t panic. It can’t hurt you unless you open it.

Rather than simply rejecting any e-mail with an attachment, you would probably be better served by first getting a good virus protection program, and then examine each one on a case by case basis.

You should automatically delete anything that ends with vbs, .bat, .zip, .exe, .pif , and .scr files. Regardless of how they may look, don’t be fooled with an attachment that looks like something else. The “Love-Letter-For-You” virus looked like a text file when it arrived and it could have been thought to be one. The attachment however ended in .vbs. and arrived with the attachment name Love-Letter-For-You.TXT.vbs.

If you take reasonable care, you should be safe from real viruses. Don’t spread false rumors about viruses that are actually hoaxes, as they will spread like wildfire, and cause a lot of people undue concern.

Why SSL is not enough to secure your credit card details

Saturday, January 2nd, 2010

SSL (secure sockets layer) is the security technology everyone uses to ensure that their web connections are secure. An SSL connection is symbolized by a padlock icon in the right-hand side of the taskbar and a URL that starts with ‘https’, the ’s’ standing for a secure http connection. What trust, however, should users associate with SSL?

Confidentiality

SSL uses a method known as public key authentication in order to provide the confidential link between the server and the client computer. This can be a very strong and effective method. It allows you to establish a strong confidential link between a server and a client without either knowing about the other beforehand. And that’s where the problems really begin.

Public key authentication works where each end of a connection can independently check that the other end is real. It’s the same idea as getting a cheque from someone you don’t know and calling their bank to see if it’s OK. That’s why it doesn’t really work. If it was going to work, the server would have to be able to find out if the client key really belonged to them or not – and it can’t. In our bank example, it’s like having a cheque without the bank name on it or the customer name the bank knows you by so that you can’t even ask the question. In fact if that happened you probably wouldn’t accept the cheque!

As a result, the server can’t tell if a hacker has diverted you via their own site and is playing a ‘man-in-the-middle’ attack where the hacker gets to see all the data going both ways. Usually the server uses an identification that has been approved by one of the companies whose information is stored inside your browser. That’s why at the client end it all seems fine. There is just the minor problem that you can’t actually tell if the identity is still valid because there’s no way in the current system to do that. Not surprisingly, there is nothing happening that allows the server to link the information arriving at it with the actual user of the client PC. It is always assumed that the information comes from there but you can’t prove it.

Is the padlock real?

Although the SSL padlock has been on the bottom of the screen for a while now, only the most adventurous have tried doing things like clicking on it. If you did you might be in for a surprise.

The first thing is that you can’t tell if the padlock is genuine. After all, anyone can write a padlock to that point on the screen, it’s not a special protected area of some kind. So seeing the padlock appear needn’t mean a secure connection is actually in place. If you do click on it you should see the web site address for the site of the server that purchased the certificate being used. You should compare this with the web site address shown in your browser tool bar. It is important to read it carefully since you are the one doing the checking, there is nothing automated about the comparison.

What needs to change?

Several things need to change before you should feel comfortable using SSL.

1) Getting enough functionality onto the client system to be able to sign and encrypt actual data instead of trying to make secure connections to places you don’t know.

2) Providing clients with the ability to check that certificates sent from servers are still genuine (check to see if they have been revoked) automatically. Then users can be sure that no man-in-the-middle can read the information they send, and that the server they are dealing with is for real.

3) The client needs an identity that can be authenticated by the server (this does not have to mean that users need to go out and buy a certificate, the server site may provide them with a suitable certificate as a separate process).

4) Automating this whole process so that the user does not have to click on the padlock icon to find out if the security is real.

Preventing Pretexting: The Privacy Protection Act of 2006

Tuesday, June 10th, 2008

What is the Privacy Protection Act of 2006?

A person’s telephone records contain valuable personal information like his billing or home address and credit card information. Unfortunately, this information can be sold or used without the knowledge of its rightful owner. To stop these illegal acts from spreading into wider territories, the United States government came up with H.R. 4709, also known as the Telephone Records and Privacy Protection Act of 2006, which protects citizens and law enforcement officials by criminalizing the act of pretexting in order to solicit or sell confidential phone records.

The timing of this law couldn’t be more perfect. Everyday, more and more people’s lives are destroyed by this terrible privacy bug. Hundreds, probably even millions, have lost many of their personal belongings and dignity because of people who have nothing but personal glory in their minds.

A positive response to the government’s new privacy law is the Federal Communications Commission’s (FCC) new set of policies that require telephone companies to execute extra caution in dealing with customers’ personal information. These policies, together with the Privacy Protection Act of 2006, will give more telephone consumers enough reason to relax and believe that they are now safe from fraudulent intruders.

The harsh penalties of the Privacy Protection Act of 2006 shall serve as a relentless warning to identity and information thieves. A person caught pretending to be someone else in order to persuade telephone companies to release confidential customer information, and the act of acquiring customer account information by the use of the Internet, or through any other fraudulent computer-related activity, will be subject to 10 years in prison and may be asked to pay a fine of $500,000.00. Only those duly authorized by federal or state laws are exempted from this law.
