Hackers over the weekend accessed Microsoft's YouTube channel to swap out videos with their own. It is unclear what the intruders' motive was, but they may have been able to access the account by stealing its login credentials from a Microsoft employee, Graham Cluley, senior technology consultant at anti-virus firm Sophos, said in a blog post Sunday. One of the unauthorized videos posted was titled "Bingo" and featured an animated video game character shooting another character. By Monday morning, the channel was operating normally. The incident followed hackers last week taking over the Sesame Street YouTube channel to display pornographic videos.
The process of delivering targeted attacks to end-users has gotten easier for attackers thanks to automated social engineering, in which adversaries can write tools that scour the web for personal data to include in their emails to increase their believability. The goal, of course, is to design messages that people are more likely to click on and, as a result, install malware on their machines or divulge personal information. In this podcast, Matias Brutti, a security consultant at security services firm IOActive, explains what the automation of social engineering means for organizations and how they can fight back.
The Twitter account belonging to the USA Today was hacked over the weekend by a group called The Script Kiddies. In tweets posted from the compromised account, the hacktivist group bragged about past hacking feats, and urged users to "like" them on Facebook and vote on who they should infiltrate next. It is unclear how the hackers were able commandeer control of the account. The same group also claimed responsibility earlier this month for hacking the NBC News Twitter account and sending a series of erroneous tweets. In that case, a trojan permitted the takeover.

It is possible splinter members are planning the attack, which is being launched over allegations that Facebook provides information about its users to government agencies and security firms, according to a YouTube video posted in mid-July. The Nov. 5 date is known as Guy Fawkes Day to commemorate the capture of the British revolutionary who plotted to blow up the House of Lords.

The latest scam to hit Facebook is trying to trick users into spreading spam with the offer of a "dislike" button, Graham Cluley, senior technology consultant at anti-virus firm Sophos, said in a blog post Monday. Many users have been clamoring for such a capability, as they could use the button to give a thumbs-down to other posts, links or uploads of which they are not fond. A "like" button already exists. The scam entices users to click on a link and install a rogue Facebook application, Cluley said. If the app is given permission to run, it posts spam messages from the user's account and prompts them to complete an online survey that makes money for the perpetrators. — AM
