Trailrunner7 writes "Robert Hansen, a security researcher and CEO of SecTheory, has been gleaning intelligence from professional attackers in recent months, having a series of off-the-record conversations with spammers and malicious hackers in an effort to gain insight into their tactics, mindset and motivation. 'He's not the type to hack randomly, he's only interested in targeted attacks with big payouts. Well, the more I thought about it the more I thought that this is a very solvable problem for bad guys. There are already other types of bad guys who do things like spam, steal credentials and DDoS. For that to work they need a botnet with thousands or millions of machines. The chances of a million machine botnet having compromised at least one machine within a target of interest is relatively high.' Hansen's solution to the hacker's problem provides a glimpse into a business model we might see in the not-too-distant future. It's an evolutionary version of the botnet-for-hire or malware-as-a-service model that's taken off in recent years. In Hansen's model, an attacker looking to infiltrate a specific network would not spend weeks throwing resources against machines in that network, looking for a weak spot and potentially raising the suspicion of the company's security team. Instead, he would contact a botmaster and give him a laundry list of the machines or IP addresses he's interested in compromising. If the botmaster already has his hooks into the network, the customer could then buy access directly into the network rather than spending his own time and resources trying to get in."

seek3r sends news of a recent test of six web application security scanning products, in which the scanners missed an average of 49% of the vulnerabilities known to be on the test sites. Here is a PDF of the report. The irony is that the test pitted each scanner against the public test files of all the scanners. This reader adds, "Is it any wonder that being PCI compliant is meaningless from a security point of view? You can perform a Web app scan, check the box on your PCI audit, and still have the security posture of Swiss cheese on your Web app!" "NTOSpider found over twice as many vulnerabilities as the average competitor having a 94% accuracy rating, with Hailstorm having the second best rating of 62%, but only after extensive training by an expert. Appscan had the second best 'Point and Shoot' rating of 55% and the rest averaged 39%."

Zerimar points out a significant flaw in Apache that can lead to a fairly trivial DoS attack is in the wild. Apache 1.x, 2.x, dhttpd, GoAhead WebServer, and Squid are confirmed vulnerable, while IIS6.0, IIS7.0, and lighttpd are confirmed not vulnerable. As of this writing, Apache Foundation does not have a patch available. From Rsnake's introduction to the attack tool: "In considering the ramifications of a slow denial of service attack against particular services, rather than flooding networks, a concept emerged that would allow a single machine to take down another machine's web server with minimal bandwidth and side effects on unrelated services and ports. The ideal situation for many denial of service attacks is where all other services remain intact but the webserver itself is completely inaccessible. Slowloris was born from this concept, and is therefore relatively very stealthy compared to most flooding tools."

An anonymous reader writes "As discussed previously on Slashdot, concern has been raised over a class of 'clickjacking' vulnerabilities which affect all major Web browsers. These exploits allow an attacker to place invisible or seemingly legit objects on a Web page that perform undesired actions when a user clicks on them. In recent developments, 'Guya' posted a scary proof-of-concept that hijacks Adobe Flash Player to spy on users with a webcam and/or microphone. In response, Adobe released an advisory with a temporary workaround, and stated that a future Player update will address the exploit. This prompted the original disclosers of the vulnerabilities to post a summary of the exploits. Additionally, Giorgio Maone, creator of the popular NoScript extension for Firefox and other Gecko-based browsers, released version 1.8.2.1 of NoScript, which adds 'ClearClick,' a feature that intercepts clicks made on invisible or otherwise obscured elements on a page. Although issues remain, there seems to be progress in addressing these security problems."

SecureThroughObscure writes "Security researcher Robert 'RSnake' Hansen discusses numerous concerns with Google's new Google Health application, which aims to integrate user's medical records online. We discussed Google Health's opening to the public earlier this week. RSnake mentions that Google has found a loophole allowing them to provide this service without having to follow HIPAA regulations, which, combined with Google's track record of having numerous flaws leading to private information disclosure, draws serious concern. Security researcher Nate McFeters of ZDNet's Zero-Day Security Blog also commented on the article, mentioning several past vulnerabilities: ownership of content issues, Google Docs theft, a cross-domain hole, Google XSS, and a Google Picasa protocol handler issue leading to the theft of user images. He and fellow researcher Billy Rios disclosed these issues to Google, including the ability to steal GMail contact list information. McFeters says it's likely that similar unpatched bugs would allow an attacker to view medical records if a user was also using Google Health. Both McFeters and Hansen tend to agree that Google's vulnerability disclosure/notification is non-existent and really needs to be improved. Currently, Google does not report vulnerabilities it has fixed to its user base, for the obvious reason of trying to hide the fact that user data could have been stolen."

An anonymous reader writes "Recent articles in the New York Times and at CNET have highlighted the growing concern that Google holds significant power and influence over Firefox's development. In an interview published today, Mozilla's technology strategist Mike Shaver did his best to proclaim Mozilla's independence. Yes, Google pays Mozilla $56 million per year, Google is the default search engine, and supplier of many of the browser's features (anti-phishing, anti-malware, incorrect URL resolution). Shaver insists that in spite of these ties, Mozilla still calls the shots over Firefox's development."

An anonymous reader writes "Dark Reading and SC Magazine covered a story about hackers posting cross-site scripting (XSS) vulnerabilies en mass on dozens of high profile websites including Dell, MSN, HP, Apple, Myspace, YouTube, MSN, Cingular, etc. The media coverage drew the hacker's attention to the publication's websites where they got a taste first-hand. On message board wall-of-shame is PC World, MacWorld, Fox News, the Independent, and ZDNet UK. "...not only did we get the "scoop" on the XSS site problems, but we also got the message loud and clear: Don't assume you're immune to XSS vulnerabilities. They're everywhere." The news comes shortly after Mitre (CVE) released statistics showing XSS has become the most popular exploit. Unfortunately new XSS attacks are growing increasingly severe and scanners are unable to find many of the issues on modern websites."

An anonymous reader writes "C|Net is reporting that JavaScript malware is opening the door for hackers to attack internal networks. During the Black Hat Briefings conference Jeremiah Grossman (CTO, WhiteHat Security) '...will be showing off how to get the internal IP address, how to scan internal networks, how to fingerprint and how to enter DSL routers ... As we're attacking the intranet using the browser, we're taking complete control over the browser.' According the the article, the presence of cross-site scripting vulnerabilities (XSS) dramatically increase the possible damage that can be caused. The issue also not which-browser-is-more-secure, as all major browsers are equally at risk. Grossman says 'The users really are at the mercy of the Web sites they visit. Users could turn off JavaScript, which really isn't a solution because so many Web sites rely on it.'"
