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. ...

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.

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. ...

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. ...

Twitter goes secure – say goodbye to Firesheep with "Always use HTTPS" option

Published: March 17, 2011 Reading time: 2 min

Sophos Labs: Good news on the social networking security front is that Twitter has finally got its act together to offer an Always use HTTPS option. If you turn on this option, all of your personalized interaction with Twitter will be encrypted – not only while you are logging in, but also while you are posting tweets. A lot of people fail to recognize the value of using HTTPS on Twitter. As long as your username and password are sent over HTTPS, so no-one can sniff them out of the ether, who cares if your tweets go over plain HTTP? After all, a tweet is meant to be public. ...

Spammers Exploit Japan’s Catastrophic State

Published: March 14, 2011 Reading time: 2 min

Symantec: Only a few days ago, Japan experienced one of the worst earthquakes in its history. The earthquake registered 8.9 on the Richter scale and triggered an enormous tsunami. The heart-wrenching images on television have left the world shaken. It was the worst earthquake and tsunami in the past century and at least 50 countries have since received related tsunami warnings. As the death and injury tolls continue to rise, one must not forget those who awake to exploit such delicate situations—spammers continue to maintain the guise of charitable institutions and governmental organizations! Don’t be surprised to suddenly see an email message in your inbox marked as URGENT and pleading with you for “monitory help” [sic] or a phishing mail urging you to donate to the rehabilitation of those affected by the quake and tsunami. Use prudence in finding out the genuine intent of email senders before you reach out or respond. ...
