Kak: A "No-Click" Email Worm

This resource have been adapted from http://www.ukans.edu/~acs/virus/kak.shtml

Is Kak On My Computer?

Check for Kak infection on your computer by scanning with an up-to-date virus scanner. Or do this:

  1. Go to the Start button, then Find and click on Files or Folders.
  2. Enter kak.htm in the Named window.
  3. Click on the Find Now button.
  4. If it finds kak.htm on your computer, go to the Removing Kak instructions.

Preventing Kak Infections

I. Patch the hole that Kak exploits:

  1. Download this Microsoft patch. Enter this URL in Internet Explorer's Address window: ftp://ftp.microsoft.com/peropsys/IE/IE-Public/fixes/usa/Eyedog-fix/x86/q240308.exe
  2. When Internet Explorer asks: "What would you like to do with this file?" choose "Run this program from its current location."

    All this patch does is force Outlook 2000 or Outlook Express to give you fair warning when they encounter something like Kak. This is the warning:

    "Some software (ActiveX controls) on this page might be unsafe. It is recommended that you not run it. Do you want to allow it to run?"

    Academic Computing Services highly recommends you answer "No" to that question whenever you see it.

II. Close the door that unsafe scripts (such as Kak) might enter:

  1. Start Internet Explorer.
  2. Go to the Tools menu and click on Internet Options.
  3. Click on the Security tab.
  4. Click once on the Internet icon (to highlight it).
  5. Click on the Custom Level button-bar (lower part of dialog box).
  6. Under Download Signed ActiveX Controls ... select Enable
  7. Under Download Unsigned ActiveX Controls ... select Disable
  8. Under Initialize And Script ActiveX Controls Marked As Unsafe ... select Disable.
  9. Click OK.
  10. Click OK (again), then shut down Internet Explorer.

III. How to keep from inadvertently spreading this class of email worms to your correspondents in the future--optional

(Outlook Express users only)

  1. Start Outlook Express.
  2. Go to the Tools menu and click on Options.
  3. Click on the Send tab.
  4. Where it says Mail Sending Format (near bottom), select Plain Text.
  5. Click OK
  6. Shut down Outlook Express.

(Outlook 2000 users only)

  1. Start Outlook 2000.
  2. Go to the Tools menu and click on Options.

Google catches up on Microsoft with new off-line software

The Guardian: Google fired another warning shot across the bows of Microsoft with the launch of software that allows people to use its services even when they are not connected to the internet.

Google Gears will help people take information from web-based programs and use it offline, enabling them to use services that usually requires a web connection on a computer's hard disk instead. The system is also being opened up to allow independent developers to create their own products based on the concept.

The announcement will be watched closely by Microsoft, which recently launched its own system, Silverlight, for bridging the gap between the online and offline worlds. The arrival of Gears could be particularly threatening because it is likely to help Google Docs, the company's suite of office software, make a concerted challenge to Microsoft's core office software business.

Docs - which incorporates word processing, spreadsheet and presentation programs - works only with an active internet connection. Allowing it to operate on a computer's hard drive would bring it into competition with the dominant Microsoft Office brand and mark the latest step in Google's slow but inexorable invasion of the Seattle-based software company's territory.

Eric Schmidt, Google's chief executive, said that giving external programmers the ability to develop system would strengthen its position.

"With Google Gears, we're tackling a key limitation of the browser in order to make it a stronger platform for deploying all types of applications," he said. "We believe strongly in the power of the community to stretch this new technology to the limits and ultimately emerge with an open standard that benefits everyone."

Court favors Microsoft in patent fight

By PETE YOST, Associated Press Writer
 
WASHINGTON - The Supreme Court sided with Microsoft Corp. on Monday in a case that restricts the reach of U.S. patents overseas.
 

In a 7-1 decision, the court found that Microsoft is not liable in a patent dispute with AT&T.

The decision could impact other lawsuits against Microsoft and save the company billions because of the global scope of its operations.

AT&T had sued Microsoft, alleging computers running the Windows operating system infringe on an AT&T technology that compresses speech into computer code.

AT&T said it is entitled to damages for every Windows-based computer manufactured outside the United States which uses the digital speech coder system.

Microsoft acknowledged violations in the United States regarding the AT&T patent, while insisting the infringement should not be extended internationally.

AT&T said Microsoft ran afoul of a 1984 law making it patent infringement for a company to ship components of a patented product to a foreign country for assembly there.

Microsoft ships its Windows-operating system to foreign countries on master disks or via electronic transmissions. That data is copied by foreign companies which install it on the computers they manufacture.

"The presumption that United States law governs domestically but does not rule the world applies with particular force in patent law," Justice

Ruth Bader Ginsburg wrote in the majority opinion.

Neither Windows software nor a computer standing alone without Windows installed infringes AT&T's patent, Ginsburg added.

U.S. patent law is inapplicable to the export of blueprints and there is no reason to think that Congress intended "to place the information Microsoft dispatched from the United States in a separate category," Ginsburg wrote.

The Bush administration supported Microsoft in the case.

Microsoft and the Bush administration say computer code is not a component until it is copied onto a hard drive or installation disk.

Copying parts abroad for assembly and sale abroad is properly the subject of foreign law, the Justice Department solicitor general's office told the court.

In a separate unanimous ruling in this area, the justices said that a federal appeals court had gone too far in embracing a standard that has fueled an era of patent protection.

The court said a federal appeals court applied the standard in a manner that is too narrow and too rigid.

The case addresses one of the most basic issues in patent law: How to determine whether a product is obvious and therefore not worthy of a patent.

"Granting patent protection to advances that would occur in the ordinary course without real innovation retards progress and may ... deprive prior inventions of their value," wrote Justice

Anthony Kennedy.

In the case of KSR International Co. v. Teleflex Inc., the U.S. Court of Appeals for the Federal Circuit in the District of Columbia had upheld a patent for adjustable gas pedals. This court hears all appeals in the field of patents.

The legal test at issue in the Teleflex lawsuit has been criticized by the Bush administration as leading to an unwarranted extension of patent protection to claimed inventions that are obvious. Critics of the test say it results in less competition and stifles innovation. Proponents warned that throwing out the standard would upset decades of settled law.

To invalidate a patent, a challenger must show that all parts of a claimed invention were known previously. In addition, the challenger must show that there is a prior "teaching, suggestion or motivation" to combine these prior technologies to produce the invention.

"Helpful insights" that the standard provides "need not become rigid and mandatory formulas," Kennedy wrote.
