Comodo Group Issues Bogus SSL Certificates

Published: April 2, 2011 Reading time: 2 min

from Schneier on Security by Schneier: This isn’t good: The hacker, whose March 15 attack was traced to an IP address in Iran, compromised a partner account at the respected certificate authority Comodo Group, which he used to request eight SSL certificates for six domains: mail.google.com, www.google.com, login.yahoo.com, login.skype.com, addons.mozilla.org and login.live.com. The certificates would have allowed the attacker to craft fake pages that would have been accepted by browsers as the legitimate websites. The certificates would have been most useful as part of an attack that redirected traffic intended for Skype, Google and Yahoo to a machine under the attacker’s control. Such an attack can range from small-scale Wi-Fi spoofing at a coffee shop all the way to global hijacking of internet routes. ...

Chrome Bookmarks Integrate with Google Search

Published: April 1, 2011 Reading time: 1 min

Google Operation System: Until recently, Google Bookmarks and Chrome Bookmarks were two separate features that didn’t speak the same language. Even if you could save your Chrome bookmarks to a Google account, they weren’t saved to Google Bookmarks. For some reason, your bookmarks are available in a special Google Docs folder. Chrome bookmarks have a web interface, but it’s likely that the obvious will happen: Chrome bookmarks could be saved to Google Bookmarks. Jérôme Flipo noticed that the Google Bookmarks OneBox already includes Chrome bookmarks. I’ve tried to find SmallNetBuilder.com and Google’s OneBox returned it even if it was starred in Chrome, not in Google Bookmarks. ...

Google +1

Published: April 1, 2011 Reading time: 2 min

Google Operation System: Google +1 is yet another attempt to make Google more social. It’s Google’s version of the Facebook “likes”, a simple feature that’s very powerful because it’s part of a social network. Google will show +1 buttons next to all search results and ads, while encouraging other sites to include the buttons. All +1’s are public and they’re tied to Google Profiles. The goal is to use this data to personalize search results and ads by recommending sites +1’d by your friends. Google Social Search already does this, but there’s no support for Facebook likes, so Google had to come up with a substitute. ...

Security Vulnerabilities in Chrome

Published: March 25, 2011 Reading time: 1 min

Avira TechBlog: It looks like new Chrome releases aren’t due every six weeks as Google announced a few weeks ago, but once a week now – the company just released Chrome 10.0.648.204 and fixes 6 highly critical security vulnerabilities with it. Those security vulnerabilities allow attackers to smuggle in malware like Trojans without the user noticing. That is why the automatic update mechanism is so important: When clicking on the tool symbol and choosing the “About Google Chrome” menu entry, the version check should show that Chrome is already on the current release – or offer to download and install the update in case that didn’t happen yet. ...

Google, Yahoo, Skype targeted in attack linked to Iran

Published: March 24, 2011 Reading time: 4 min

Cnet: A malicious attacker that appears to be the Iranian government managed to obtain supposedly secure digital certificates that can be used to impersonate Google, Yahoo, Skype, and other major Web sites, the security company affected by the breach said today. Comodo, a Jersey City, N.J.-based firm that issues digital certificates, said the nine certificates were fraudulently obtained, including one for Microsoft’s Live.com, have already been revoked. A fraudulent certificate allows someone to impersonate the secure versions of those Web sites–the ones that are used when encrypted connections are enabled–in some circumstances. ...

Talking to your computer (with HTML5!)

Published: March 23, 2011 Reading time: 1 min

Google Chrome Blog: Today, we’re updating the Chrome beta channel with a couple of new capabilities, especially for web developers. Fresh from the work that we’ve been doing with the HTML Speech Incubator Group, we’ve added support for theHTML5 speech input API. With this API, developers can give web apps the ability to transcribe your voice to text. When a web page uses this feature, you simply click on an icon and then speak into your computer’s microphone. The recorded audio is sent to speech servers for transcription, after which the text is typed out for you. Try it out yourself in this little demo. Today’s beta release also offers a sneak peek of GPU-accelerated 3D CSS, which allows developers to apply slick 3D effects to web page content using CSS. ...

Gmail Blog: Posted by Jason Toff, Product Marketing Manager Switching email accounts can be painful. The idea of losing years of accumulated contacts and messages can sound daunting, to say the least. Luckily, switching to Gmail doesn’t mean you have to start totally fresh. Back in 2009 we announced tools that let you import mail and contacts from other providers, such as AOL or Hotmail. Today we’re announcing the addition of fourteen more international domains to our list of supported email providers: ...

Data loss at Play.com

Play.com, one of the largest online retailers of DVDs, CDs, MP3s, books and gadgets, emailed its customers yesterday admitting to a security breach in its marketing communications. Names and emails may have been compromised. Play.com claims the breach happened outside its walls, so presumably they use a third party marketing consultancy to manage part or all of its marketing activities. Here is one of the messages that was sent out to customers by Play.com: ...

Firefox Extension Used in Facebook Scam

Published: March 23, 2011 Reading time: 3 min

Symantec Connect: Not only Facebook is adding new and interesting features to its toolbox; spammers and scammers in Facebook are, too. Currently there is a scam making rounds using a classic “who is viewing your profile” themed bait. So far – nothing new. After the user grants the application the requested privileges, which of course will send out the above mentioned spam posts to all his or her friends, the user gets redirected to a download instruction site. There he or she is asked to download the Firefox browser and then install a popular Firefox extension which allegedly gets downloaded over 27,000 times per week. This simple tweak should generate a new menu entry in Facebook which would then show user statistics. ...
