On Tuesday, Microsoft issued new tools to assist Microsoft ASP and ASP.NET technologies against recent Web-based attacks.

In April attackers went after Microsoft SQL sites by injecting malicious JavaScript onto legitimate sites. The JavaScript would direct a browser to a server hosting malicious software infecting the desktop with a variety of exploits. At the time Microsoft insisted it was not the result of a vulnerability, but lack of best practices on the sites themselves.

The tools released Tuesday are designed to help Web developers mitigate against such attacks.

"These free tools offer detection and defense, as well as … Read more

Last week on my Security Bites podcast I talked with Jeremiah Grossman, CTO of WhiteHat Security, about the recent spate of SQL injections affecting Microsoft SQL.

Grossman said that if users surf to an SQL-injected site, their browsers will attempt to download a variety of exploits, not all of which are Microsoft-based. One site from the Shadowserver Foundation lists exploits affecting Real and other vendors alongside various Microsoft Security bulletins. Grossman also said that just turning off Javascript won't necessarily protect end users from this latest round of attacks since the attackers can use traditional HTML as well.

Progress was made Monday in mitigating thousands of SQL-based Web sites injected with malicious Javascript code. However, one security expert says we can expect more such attacks in the near future.

A traditional SQL injection attack allows malicious attackers to execute commands on an application's database by injecting executable code. "What's different about this latest attack is the size and the level of sophistication," said Jeremiah Grossman, CTO of WhiteHat Security.

In the past, attackers have gone after a small niche of the Internet--say travel sites or sports sites--but with this latest attack, attackers have a … Read more

Microsoft is denying that a recent rash of Web server attacks are the company's fault.

In a blog posted late Friday night, Bill Sisk, of the Microsoft Security Response Center, wrote that the attacks are not due to any new or unknown security flaws in Internet Information Services or Microsoft SQL Server. Rather, he says, the attacks are made possible by SQL injection exploits, and he points Web developers to the company's list of best practices to prevent such attacks.

Ongoing attacks have affected half a million Web pages, compromising them so they serve up malware, according to … Read more

Comparisons between two mass Javascript injection attacks suggest they may be related, according to a security company. The latest attack has compromised various sites including one United Nations and several UK government sites with links to malicious servers.

On Tuesday Websense reported seeing distinct similarities between attacks staged earlier this month and over the weekend. Specifically, they cite the use of the same tool to execute the attack being resident on the malicious server. Last summer various groups used the MPACK toolkit to propagate a similar series of Javascript injections.

Javascript injections are browser attacks and require no more effort … Read more

Want to cause trouble at RSA? Register with any of a number of special characters in your name or business name and watch the badge printer issue blanks. That's what happened to me.

Monday morning when I registered for RSA 2008 (where I'll be speaking with Chris Boyd of FaceTime), I thought maybe I'd get a little VIP service. (Our talk on "How to Adapt to the Echo Generation's Social Media Hacking Game" is at 9:10 a.m. PDT on Thursday.) Instead, I was stuck in various registration lines for more than half … Read more

On Monday, Adobe Systems rolled out its new Web 2.0 development tool, Adobe Integrated Runtime, or AIR. Following its release were some concerns from the security community.

AIR, formerly Adobe Apollo, is a runtime environment that allows developers use HTML, Flash, AJAX, Flex, and other Web 2.0 tools to create desktop applications. One such application built using Adobe AIR comes from Nickelodeon Online.

But some security experts are concerned about local file access by AIR applications. Recently, Firefox experienced a vulnerability that could have allowed remote attackers to access a targeted file system. To mitigate this, Adobe says … Read more

On Wednesday, the SANS Internet Storm Center and others published details about the massive SQL-based Web attack that occurred over the weekend. The attack, says SANS, is similar to a smaller SQL-injection attack seen in November. At least 70,000 sites were compromised in a short period of time, leading some to speculate this was an automated attack.

From logs files, the attack code appears to exploit a variety of SQL injection vulnerabilities existing on Web sites using Microsoft SQL or Microsoft IIS. On the vulnerable sites, malicious JavaScript is injected into all variable character fields and text fields in … Read more
