New hacked site notifications in search results

Published: December 20, 2010 Reading time: 2 min

Today we’ve added a new notification to our search results that helps people know when a site may have been hacked. We’ve provided notices for malware for years, which also involve a separate warning page. Now we’re expanding the search results notifications to help people avoid sites that may have been compromised and altered by a third party, typically for spam. When a user visits a site, we want her to be confident the information on that site comes from the original publisher. Here’s what the notification looks like: ...

Don’t Lie to Me, Angelina!

Published: December 15, 2010 Reading time: 2 min

Earlier this year I received a Facebook invite in my Yahoo! Mail account from none other than Angelina Jolie herself. I kid you not. While it’s true that we live in the Digital Age where communicating with anyone is a mere tap of a finger away—whether it’s via email, IM, Facebook, Twitter, etc.—the chances that Ms. Jolie would randomly reach out to a regular Joe, such as myself, is still pretty darn improbable. So, the following questions raced through my mind: ...

The top 50 passwords you should never use

Published: December 15, 2010 Reading time: 2 min

Are you one of the many people who is using a dangerously easy-to-guess password? Maybe now’s the time to fix that before it’s too late. Twitter, LinkedIn, World of Warcraft and Yahoo are amongst the popular websites which are advising users to change their passwords in light of the recent security breach at the Gawker Media family of sites. The issue is that many people (33% in our research) use the same password on every single website. That means that if your password gets stolen in one place (like Gawker’s Gizmodo or Lifehacker websites), it can be used to unlock access to other sites too. ...

QuickTime 7.6.9 update resolves 15 vulnerabilities

Published: December 11, 2010 Reading time: 2 min

This week Apple announced the availability of QuickTime 7.6.9 for OS X 10.5 and Windows platforms. This release fixes 13 vulnerabilities in QuickTime for OS X Leopard and 15 vulnerabilities on the Windows platform. Keep in mind that if you use iTunes it requires that you install QuickTime as well, so be sure to check for updates. Apple has provided a direct download link for IT folks at http://www.apple.com/quicktime/download/. All 13 vulnerabilities for OS X can cause unexpected application termination (what you and I call a crash, but you can’t say crash on a Mac) or arbitrary code execution (make QuickTime run programs… BAD). ...

Dutch police website attacked after arrest of suspected hacker

Published: December 11, 2010 Reading time: 1 min

Just a day after Dutch police arrested a 16-year-old boy in connection with WikiLeaks-related denial-of-service attacks, websites belonging to the Netherlands computer crime cops and prosecutors have been struck with a similar assault. Dennis Janus, a spokesman for the National Police Service confirmed that both the police website, and that of the National Prosector’s Office had been offline for much of the day, with many theorizing that the likely reason is a distributed denial-of-service (DDoS) attack similar to that which was launched against MasterCard, PayPal and other firms. ...

Semi-nude pictures of Christina Aguilera leaked onto the internet earlier this week, causing fans of the pint-sized pop diva to feverishly run to their search engines in the hunt for the private snaps. Regular readers should know only too well about the dangers that can be associated with hunting for such material – with nude pictures of Twilight star Ashley Greene and snaps of princess-to-be Kate Middleton recently being used as bait for the unwary. ...

Spam Carrying WikiLeaks Worm

Published: December 7, 2010 Reading time: 2 min

Symantec Connect: WikiLeaks.org is in the news after their recent publications linked to leaked government documents. Spammers are now leveraging the current level of interest with social engineering techniques to infect users’ computers. Symantec is observing a wave of spam spoofing WikiLeaks to lure users into becoming infected with a new threat. The spam email has subject line “IRAN Nuclear BOMB!” and spoofed headers. The “From” header purports to originate from WikiLeaks.org, although this is not in fact the case, and the message body contains a URL. This URL downloads and runs WikiLeaks.jar which has a downloader ‘WikiLeaks.class’ file. The downloader pulls the threat from http://ugo.file[removed].com/226.exe. Symantec detects this threat as W32.Spyrat. ...

Taking a look at fake Amazon receipt generators

Published: December 7, 2010 Reading time: 3 min

Sunbelt Blog: Above, you can see a vaguely optimistic VirusTotal user summary in relation to a file that’s been doing the rounds for about a month or two. Here is the file in question: A “receipt generator”, I hear you ask – what do people want with one of those? The answer, of course, is rather straightforward: This is a particularly interesting scam, as it doesn’t target regular PC users – it targets the people who sell you things, such as the merchants on the Amazon marketplace. This is what the would-be social engineer sees when they fire up the program: ...

Twitter Trend Poisoning Cookbook

Published: December 7, 2010 Reading time: 7 min

Symantec Connect: We have become familiar enough with malware creators poisoning popular search engine terms through SEO techniques in order to deliver their malicious files to a greater pool of unsuspecting users. Other popular services such as Twitter have not escaped the watchful eyes of the miscreants. This attack involves pumping out many of the same tweets with different accounts to push them into the Twitter trending list. That way more people are likely to see them even if the individual user accounts being used to send the tweets don’t have that many followers. Incidentally many of the accounts used in this attack don’t have that many followers and are quite fresh – meaning they are probably fake accounts set up specifically for the purpose of spamming tweets. ...

Looks familiar? Yes! From Alureon!

Published: December 7, 2010 Reading time: 2 min

It’s a normal day to us. We receive a new Bamital virus sample report from a customer, and we provide an analysis. Suddenly, something interesting bursts into my eyes: What’s your thought on this code fragment? At the first glance, this piece of code looks like a non-malicious call to manipulate the Windows Printer SubSystem. But if you’ve analyzed Alureon before, it may look familiar to you. Yes, Alureon also takes advantage of the Windows Print Subsystem to install its payload. ...

Improved Avira AntiVir Rescue System

Published: December 7, 2010 Reading time: 1 min

Avira programmers spent a lot of work and drastically overhauled the Avira AntiVir Rescue System which is now available in version 3.7.16. Next to a much better usability due to the redesigned user interface and 11 supported languages the new version offers even improved detection and removal capabilities.

The bootable CD can not only be used to analyse the system for malware infections and remove them, but also enables the user to get access to data on the system in case the operating system won’t start anymore so it can be backed up onto a USB drive, for example. ...

Take a look in the Email I got from Google a few minutes ago: Dear Website Optimizer user, We are writing to inform you of a potential security issue with Website Optimizer.
