Security loophole found in Windows operating system

14.11.2007
A group of researchers headed by Dr. Benny Pinkas from the Department of Computer Science at the University of Haifa succeeded in finding a security vulnerability in Microsoft's "Windows 2000" operating system.

The significance of the loophole: emails, passwords, credit card numbers, if they were typed into the computer, and actually all correspondence that emanated from a computer using "Windows 2000" is susceptible to tracking. "This is not a theoretical discovery. Anyone who exploits this security loophole can definitely access this information on other computers," remarked Dr. Pinkas.

Various security vulnerabilities in different computer operating systems have been discovered over the years. Previous security breaches have enabled hackers to follow correspondence from a computer from the time of the breach onwards. This newly discovered loophole, exposed by a team of researchers which included, along with Dr. Pinkas, Hebrew University graduate students Zvi Gutterman and Leo Dorrendorf, enables hackers to access information that was sent from the computer prior to the security breach and even information that is no longer stored on the computer.

The researchers found the security loophole in the random number generator of Windows. This is a program which is, among other things, a critical building block for file and email encryption, and for the SSL encryption protocol which is used by all Internet browsers. For example: in correspondence with a bank or any other website that requires typing in a password, or a credit card number, the random number generator creates a random encryption key, which is used to encrypt the communication so that only the relevant website can read the correspondence. The research team found a way to decipher how the random number generator works and thereby compute previous and future encryption keys used by the computer, and eavesdrop on private communication.

"There is no doubt that hacking into a computer using our method requires advanced planning. On the other hand, simpler security breaches also require planning, and I believe that there is room for concern at large companies, or for people who manage sensitive information using their computers, who should understand that the privacy of their data is at risk," explained Dr. Pinkas.

According to the researchers, who have already notified the Microsoft security response team about their discovery, although they only checked "Windows 2000" (which is currently the third most popular operating system in use) they assume that newer versions of "Windows", XP and Vista, use similar random number generators and may also be vulnerable.

Their conclusion is that Microsoft needs to improve the way it encodes information. They recommend that Microsoft publish the code of their random number generators as well as of other elements of the "Windows" security system to enable computer security experts outside Microsoft to evaluate their effectiveness.

Im Focus: Neutron star merger directly observed for the first time

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event

On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...

Im Focus: Breaking: the first light from two neutron stars merging

Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.

Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....

Im Focus: Smart sensors for efficient processes

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).

When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...

Im Focus: Cold molecules on collision course

Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.

How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...

Im Focus: Shrinking the proton again!

Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.

It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
