Katrina scam artists get busy

The FBI says there are now 2 300 Web sites advertising Hurricane Katrina relief services, and most of them are presumed to be bogus, reports CNN.

In addition, scammers are four times more prevalent than after the tsunami disaster, according to the watchdog site Scambusters.

Scams include phishing, viruses, Trojans and fee-based spam.

The Justice Department, which has established a Hurricane Katrina Fraud Task Force to focus on such scams, recommends going directly to recognised charities and aid organisations` Web sites, as opposed to following a link to another site.

Responding to the disclosure of a serious Web browser flaw, the Mozilla Foundation has offered a temporary fix to protect Firefox and Mozilla users, reports CNET.

The downloadable fix protects against attacks that take advantage of a new, unpatched flaw that could let attackers secretly unleash malicious software on users` PCs.

"This is a temporary work-around just to deal with the immediate issue," said Mike Schroepfer, director of engineering at Mozilla.

"We`re working on a future release in which we will actually fix the problem and re-enable the IDN feature."

Cisco has warned that some configurations of IOS contain vulnerabilities that could lead to a sustained denial-of-service attack or execution of arbitrary code, reports Enterprise Networking Planet.

In an advisory posted on its Web site, Cisco warned that its IOS Firewall Authentication Proxy for FTP and Telnet sessions is vulnerable to a remotely exploitable buffer overflow flaw.

The company said devices that aren`t configured for, or don`t support, the feature aren`t vulnerable, neither are devices configured with only Authentication Proxy for HTTP and/or HTTPs.

According to Cisco, the affected versions of IOS include versions 12.2ZH, 12.2ZL, 12.3T, 12.4 and 12.4T while products running IOS version 12.2 or lower or IOS XR are not affected.

NerdTV identifies its target audience with its name and format: it`s not available over the air but rather via a free Internet download, reports BusinessWeek online.

The tech-focused interview show, created by pundit and PBS host Robert Cringely, is meant to be unlike anything on regular TV or elsewhere on the Internet, where video tends to come in short clips.

Instead, this is a "Charlie Rose"-style chat, about an hour long, with "some incredibly smart person you always wanted to meet," Cringely says.
