Did you notice when Slashdot's  search was down for the past few days? (It's back up now.)  Turns out that in a stunning case of irony, it had been hammered into  submission by thousands of people attempting to use it.        However, unlike CmdrTaco's regimented DDoS attacks, this one is carried out  with malicious intent as opposed to mere sociopathic inconsiderateness.  It also highlights a potential threat from one of the biggest weblogging  services out there.

The Web is scarier than most people realize, according to research published recently by Google.The search engine giant trained its Web crawling software on billions of Web addresses over the past year looking for malicious pages that tried to attack their visitors. They found more than 3 million of them, meaning that about one in 1,000 Web pages is malicious, according to Neils Provos, a senior staff software engineer with Google.These Web-based attacks, called &quot;drive-by downloads&quot; by security experts, have become much more common in recent years as firewalls and better security practices by Microsoft have made it harder for worms and viruses to directly attack computers.In the past year the Web sites of Al Gore&#39;s An Inconvenient Truth movie and the Miami Dolphins were hacked, and the MySpace profile of Alicia Keys was used to attack visitors.Criminals are getting better at this kind of work. They have built very successful automated tools that poke and prod Web sites, looking for programming errors and then exploit these flaws to install the drive-by download software. Often this code opens an invisible iFrame page on the victim&#39;s browser that redirects it to a malicious Web server. That server then tries to install code on the victim&#39;s PC. &quot;The bad guys are getting exceptionally good at automating those attacks,&quot; said Roger Thompson, chief research officer with security vendor Grisoft.In response, Google has stepped up its game. One of the reasons it has been scouring the Web for malicious pages is so that it can identify drive-by-download sites and warn Google searchers before they visit them. Nowadays about 1.3 percent of all Google search queries list malicious results somewhere on the first few pages.Some of the data surprised Provos.&quot;When we started going into this, I had the firm intuition that if you go to the sleazier parts of the Web, you are in more danger,&quot; he said.It turns out the Web&#39;s nice neighborhoods aren&#39;t necessarily safer than its red-light districts.&quot;We looked into this and indeed we found that if you ended up going to adult-oriented pages, your risk of being exposed [to malicious software] was slightly higher,&quot; he said. But &quot;there really wasn&#39;t a huge difference.&quot;&quot;Staying away from the disreputable part of the Internet really isn&#39;t good enough,&quot; he noted.Another interesting finding: China was far and away the greatest source of malicious Web sites. According to Google&#39;s research, 67 percent of all malware distribution sites are hosted in China. The second-worst offender? The U.S., at 15 percent, followed by Russia (4 percent), Malaysia (2.2 percent), and Korea (2 percent).It costs next to nothing to register a Web domain in China and service providers are often slow to shut down malicious pages, said Thompson. &quot;They&#39;re the Kleenex Web sites,&quot; he said. Criminals &quot;know they&#39;re going to be shut down, and they don&#39;t care.&quot;Malicious site operators in China fall into two broad categories, Thompson said: Fraudsters looking to steal your banking password, and teenagers who want to steal your World of Warcraft character.So how to stop this growing pestilence?Google&#39;s Provos has this advice for Web surfers: Turn automatic updates on. &quot;You should always run your software as updated as possible and install some kind of antivirus technology,&quot; he said.But he also thinks that Webmasters will have to get smarter about building secure Web sites. &quot;I think it will take concentrated efforts on all parts,&quot; for the problem to go away, he said.

(InfoWorld) - Google quickly patched what security researchers identified Wednesday was a potentially serious cross-site scripting flaw in its popular desktop search and widget application that could leave users vulnerable to outside attack. In a report, researchers at application security software maker Watchfire, based in Waltham, Mass., detailed an existing attack designed to exploit the Google Desktop flaw. Watchfire said the cross-site scripting threat -- which it described as a parasitic virus -- could allow attackers to steal information from affected PCs and track end users' Web browsing habits. Cross-site scripting (XSS) threats typically take advantage of security vulnerabilities in legitimate Web pages to inject malicious content into the browsers of people visiting the URLs or to redirect them to fraudulent sites used in phishing attacks. Like many other XSS threats, the attack currently leveled at Google Desktop uses JavaScript code to deliver its payload. Watchfire experts said the Google Desktop XSS problem was very dangerous for a number of reasons. Among the more serious characteristics is the malicious program's ability to affect clusters of computers connected by Google Desktop's information sharing capabilities. This could allow attackers to spread the attack to new machines or simply steal data from multiple PCs linked by the application. Most enterprises have invested significant amounts of time and money installing security applications to protect against the loss of sensitive data over the last several years, but a Google Desktop attack would circumvent many of those systems, leaving information on corporate desktops running the program open for potential theft. "This attack is almost undetectable, it won't get picked up by any anti-virus system or firewall, and it can be used in a lot of different ways to harm end users," said the director of security research at Watchfire, Danny Allen. "It allows someone using the attack to control all the applications on a computer or access the network to which an affected machine is attached, and it is almost impossible to get rid of." As part of a demonstration of the exploit, Allen showed off how the program could be used to change the version number in the Google Desktop application itself. Doing so could allow attackers to fool users of the desktop search program into believing they have a version of the software that has been fixed for security reasons, when in fact they are still potentially vulnerable. "Some IT security people have dismissed the impact of [cross-site scripting] attacks to a certain extent, but we wanted to highlight the potential damage that something like this could deliver," Allen said. Media representatives at Google said that after Watchfire informed the company of the attack, engineers at the search giant created a patch for the issue that was automatically distributed to Google Desktop users. Google said it has also added a new set of security features to the latest iteration of the product to prevent similar attacks in the future. On Feb. 9, Google launched its newest version of the desktop search program, labeled Desktop 3 Beta. Company representatives said that they have not received any reports of the vulnerability being exploited on end-users' machines. Watchfire researchers said the new security patch appears to fix the flaw and prevent XSS attacks on users of Google Desktop whose systems have been updated. Security analysts considering the problem said it highlighted the need for businesses to look carefully at programs such as Google Desktop that straddle the line between personal and professional PC usage. Although the application may be very useful, and most often gets pulled into the corporate environment by people who use it at home, Google is not a maker of business-grade software and doesn't follow the same security processes as large manufacturers of such products, said John Pescatore, analyst at Gartner. Unlike Microsoft, Oracle, or Sun Microsystems, Google does not publish regular security bulletins or even offer specific details of issues it has already fixed, Pescatore said. This reason, along with the data security issues that can be introduced when Google Desktop isn't configured to bar users from inadvertently sharing search information with outsiders, poses serious questions for corporate IT administrators who must decide whether to allow people to use it in the office, according to the analyst. "The major concern is that while Google isn't an enterprise software vendor, programs it makes, including Google Desktop, are ending up on a lot of enterprise desktops," Pescatore said. "Google doesn't expose how it does patches like Microsoft, so how does an enterprise even know if their users are working with the version that has been fixed?" As malware writers and phishing scheme operators continue to hone their attacks to steal smaller amounts of valuable data from pools of targeted users, and move further away from the massive worm viruses of years past, the IT world will see more XSS threats. "There will be more funded cyber-crime attacks aimed at specific companies and groups of users, and the size of the threats is such, by design, that they won't land on the six o'clock news," Pescatore said. "The perpetrators will continue to increase the volume of these types of threats, and cross-site scripting and targeted phishing will likely be among their favorite formats for doing so." The bug, which was made public Wednesday by Watchfire, has now been fixed. While Google is automatically delivering a patch, Google Desktop users who want to be sure they are running the latest version of the software can download it here. Users should be running version 5.0.701.30540 or later, said Google Spokesman Barry Schnitt. Google was first notified of the problem on Jan. 4 and produced its fix on Feb. 1, a Watchfire spokesman said Wednesday. In addition to its bug fix, Google has added, "another layer of security checks to the latest version of Google Desktop to protect users from similar vulnerabilities in the future," Schnitt said. "We have received no reports that this vulnerability was exploited.â Robert McMillan of IDG News Service contributed to this report.
