Bottom line, copied here: * If you are using Microsoft Outlook or Outlook Express, quit it. Find and use something else. Here are some suggestions: http://www.lsit.ucsb.edu/mail/tools/compare.php * If you are using Microsoft Windows operating system, quit it. Find and use something else, like Linux or Macintosh. ================================= In the last few years, wave after wave of viruses, worms, Trojan Horses, and other communicable destructive programs have rocked the Internet. A very few -- the infamous "Internet Worm" of 15 years ago for example -- attacked UNIX computers. Most of the rest attacked Microsoft computers. Why has Microsoft been the major target? Because it is big? Of course. Microsoft's size is a factor. But Microsoft software is particularly suitable for harboring and proliferating these attack programs. Let us consider an analogy. In days gone by, many wealthy homes employed butlers. The butler was a combination bouncer, guard dog, and chief servant, among other things. When a visitor came to the door, the visitor had to prove that he was harmless and worthy of entry before he set foot in the door, and the butler was the judge. It was a case of convince-the-butler-or-stay-out. That is the normal and expected behavior of a good email program. But suppose you had a butler who threw open the door, and immediately became the personal slave of anyone standing there. "Run through the house and smash up the precious china." "Immediately, Sir." "Open the safe and hand over the contents." "Of course, Sir." "Publish the master's private conversations." "At your command, Sir." Such is the fatal flaw in Microsoft Outlook email and some other Microsoft programs. Usually, the commands in the email are harmless or even useful magic, and no one minds: enter dates on the personal calendar, play music, show pictures, etc. But specially designed virus/worms can erase files, corrupt programs, download other programs, publish personal passwords, and mail copies of themselves to other computers. Whatever the destructive program tells it to do, Microsoft Outlook does, with all the power of the computer and all the authority of a trusted butler gone mad. The Outlook email software is not the only traitorous servant in the Microsoft mansion. A few years ago, vandals were building attack programs that used the power of the Microsoft spreadsheet program (Excel) and the Microsoft word processor (Word) as slaves for these destructive programs. Currently, a number of worms use "remote procedure calls" (RPC) to travel between Microsoft systems. RPC was recognized a decade ago as a security threat, and it is forbidden by most conscientious UNIX administrators and designers. The weakness in Microsoft is this willing obedience to take instructions from strangers. Why does the butler take orders from the stranger who comes to the door? Isn't this an obvious invitation to vandals? Indeed it is, as any review of the virus/worm history shows. Of the more than a hundred virus/worms identified by Symantec in the last month, all of them exploit vulnerabilities in Microsoft. Certainly, viruses have attacked Macintosh and Linux computers, but the threats are relatively rare, as a browse through the virus info library shows. But Linux and Macintosh computers often use Microsoft-adopted programs, and when Linux and Macintosh computers are attacked, it often comes through Microsoft programs (as does the one virus in the list that attacks Macintosh -- It infects Microsoft Word documents). (see http://securityresponse.symantec.com/avcenter/vinfodb.html) Consider the worm, [EMAIL PROTECTED] for example, a nuisance that appeared on about August 18, 2003. This worm comes in on an email message entitled * Re: Details * Re: Approved * Re: Re: My details * Re: Thank you! * Re: That movie * Re: Wicked screensaver * Re: Your application * Thank you! * Your details and invites the reader to "See the attached file for details." The recipient who opens the attached file accidentally turns his computer over to the worm, which then goes into action. Among other tricks, the worm opens the personal address book and floods the net with copies of itself embedded in emails: "Email spoofing [EMAIL PROTECTED] uses a technique known as 'spoofing,' by which the worm randomly selects an address it finds on an infected computer. The worm uses this address as the 'From' address when it performs its mass-mailing routine. Numerous cases have been reported in which users of uninfected computers received complaints that they sent an infected message to another individual. "For example, Linda Anderson is using a computer infected with [EMAIL PROTECTED] Linda is neither using an antivirus program nor has the current virus definitions. When [EMAIL PROTECTED] performs its email routine, it finds the email address of Harold Logan. The worm inserts Harold's email address into the "From" portion of an infected message, which it then sends to Janet Bishop. Then, Janet contacts Harold and complains that he sent her an infected message; however, when Harold scans his computer, Norton AntiVirus does not find anything, because his computer is not infected." (http://securityresponse.symantec.com/avcenter/venc/data/[EMAIL PROTECTED]) To a security professional, the willingness of Microsoft computers to run hostile software is a staggering vulnerability, and it has become worse with the newer software, not better. Almost ten years ago, Sun Computers published the Java standard, whereby "stranger" software could be downloaded from the web and run without fear. Java uses a "sandbox" to run the stranger program, whereby the stranger is permitted to do any graphical trick on the screen or sound system, but is forbidden to touch the file system or use the network. The stranger program is locked harmlessly in the sandbox. Compare this with the Microsoft model, where the stranger program can open files on the disk, mail out copies of itself, download other programs, and even erase important system files, all without the knowledge of the computer owner. OK, Microsoft makes imperfect software, you say? What is wrong with this explanation? Microsoft has pounded almost every other computer operating system and software company into the ground. All the others have shrunk into the shadows, or disappeared from commercial America. The computer race has gone to neither the swift nor the strong, but to a poor, weak, lowball contender. The story on this is full of unpublished details. As long ago as 1993, the US government recognized Microsoft as the Chosen Software, the obligatory standard. The government required proposals from corporations for government contracts to the Defense Department and other federal agencies to be submitted in printed and electronic form -- and that electronic form was Microsoft Word. There were a number of other word processing programs available at the time, but the government mandated Microsoft. This meant that government desks that studied the proposals must all use Microsoft. It also meant that corporations that hoped to do business with the federal government must all use Microsoft. A year or so later, the Defense Department mandated that every Defense desktop computer must use Microsoft. Hundreds of thousands of desktops became locked into the Chosen customer base. When the Defense Department settled on a design for the mighty Defense Messaging System to carry the ultra-secret messages of the military, Microsoft was again the chosen platform -- for about another million systems. Look again at the catalog of worms discovered in the month of August, 2003 (see http://securityresponse.symantec.com/avcenter/vinfodb.html), and consider -- why Microsoft? In the mid-1990s, Microsoft invented Active X and used it for web page magic in competition with Java. So many security holes were found in Active X, it died the terrible death of infamy. When the destructive macro worms first started appearing in the late 1990s, infecting Word documents and emails, who was blamed by the FBI? Computer administrators who failed to run a tight ship, of course, and university punks who deserve jail time for writing prank worms. Not a single word of opprobrium was spoken about the soft underbelly of Microsoft. Scan any news article about computer worms and viruses -- is the Microsoft weakness ever mentioned? Never. Yet look at this evaluation of email packages by the College of Letters and Science, University of California, Santa Barbara. http://www.lsit.ucsb.edu/mail/tools/compare.php Of Microsoft Outlook, LSIT says: "Often used to propagate viruses." Microsoft Outlook is only program mentioned with that vulnerability. If Ford Motors produced cars that ran on bubble gum tires instead of vulcanized rubber, would you expect to see Ford become the Chosen Automobile of the future? Put in other words, Why Does Microsoft Prosper? It seems that Microsoft prospers because the US Government wants it that way. Can anyone think of another reason? Few people know anything else exists beyond Microsoft, bugs, worms, and problems. One part of that can still be solved, now, today. * If you are using Microsoft Outlook or Outlook Express, quit it. Find and use something else. Here are some suggestions: http://www.lsit.ucsb.edu/mail/tools/compare.php Also try Opera from http://www.opera.com. Some of those programs are free. * If you are using Microsoft Windows operating system right now, quit it. Find and use something else, like Linux or Macintosh. Linux is cheaper, Macintosh is easier. Microsoft programs, even on these systems, have often provided easy access for worms and viruses. In this respect, a Microsoft program operates as a Trojan Horse in a system that is otherwise secure. If civilian America insists on using Microsoft, it is easy to predict what will happen next: Civilian America will be so overwhelmed with worms, viruses, Trojan Horses, and other bugs that civilian America will scream for an end to free e-mail and information interchange -- and the monopoly on information will be returned to the Media Lords. ==== Some Definitions: Virus: A small, parasitic computer program. The virus analogy comes about because viruses often function by attaching themselves to legitimate programs, and because they have the ability to replicate themselves, copying from one program to another. When an infected program is copied to another computer, the virus is passed also. Viruses are often designed to harm or destroy the host system. Worm: A virus with additional network intelligence so that it can "crawl" through a network infecting computers as it goes. The worm [EMAIL PROTECTED] reads address books and mails itself to other computers. There are many email worms, and there are other types of worms, too. Trojan horse: A "con-man" program that contains hidden destructive functionality. For example, Program X is advertised as a cheap firewall that stops virus infections. On test, Program X does that, but it also records credit card numbers as they are entered for Internet purchases, and secretly mails the information to the thief. The FBI has publicly discussed using Trojan Horse programs to capture file encryption passwords, so that the FBI can decrypt and read the files when they seize computers for evidence.
