Tech Scrape

The company hopes a “smart pedal” will help defuse criticism.

Both cases involved Priuses: one in Harrison, NY, that resulted in a crash, and the other on an interstate east of San Diego.

Security firm aims to make installing updates as painless and invisible as possible. Recent research shows that the typical PC user needs to install a security update roughly every five days in order to safely use Microsoft Windows and all of the third-party programs that typically run on top of it. In response, a Danish computer security firm says it will soon debut a free new service that silently automates the installation of security updates for dozens of the most commonly used software products.

New software aims to expose mobile malware by monitoring a device’s memory usage. Yesterday at the RSA Conference in San Francisco, a researcher presented a new way to detect malware on mobile devices.

Tablets powered by Google’s mobile operating system are set to debut. Apple’s iPad is certain to grab headlines when it hits stores next month. But a number of touch-screen tablets powered by Google’s Android operating system will also debut this year. Competing with Apple’s latest consumer gadget won’t be easy, but analysts say the software behind these devices could give them a few key advantages.

A new tool explores large sets of data–and might help organize the Web. “How do you take a big collection of things and make sense out of it?” asks Gary Flake , founder and director of Microsoft Live Labs , a division of the software giant that designs experimental Web tools. The problem is becoming more common, even for the average user, because the Web makes huge quantities of information readily available.

Chrome OS is ridiculously simple–and that’s why you’ll love it. Most of this article was written on a six-year-old computer running Google’s new Chromium OS.

A kit lets beginners craft sophisticated attacks. In 2005, a Russian hacker group known as UpLevel developed Zeus, a point-and-click program for creating and controlling a network of compromised computer systems, also known as a botnet. Five years of development later, the latest version of this software, which can be downloaded for free and requires very little technical skill to operate, is one of the most popular botnet platforms for spammers, fraudsters, and people who deal in stolen personal information.

A new tool blocks files that try to install without alerting the user. Researchers at SRI International and Georgia Tech are preparing to release a free tool to stop “drive-by” downloads: Internet attacks in which the mere act of visiting a Web site results in the surreptitious installation of malicious software. The new tool, called BLADE (Block All Drive-By Download Exploits), stops downloads that are initiated without the user’s consent.
