LulzSec Releases Over 62.000 Hacked Passwords

Hacker group LulzSec published the accounts of over 62,000 emails and passwords for free for download.

Mikko H. Hypponen from F-secure believes that the emails and passwords were from a database kept by website Writerspace.com, according to the Hacker News.

Gizmodo took the database and has made a script for users to input their email address to check it against the release from LulzSec. Unless you were a member of Writerspace, you're probably not affected, but this is a good way to confirm.

Chinese Gmail Attack Targets 'Senior' U.S. Officials

Image representing Gmail as depicted in CrunchBaseGoogle revealed the suspected source of a hacking attack on Gmail accounts: users originating in China.

Eric Grosse, engineering director on the Google Security Team, said in a blog post Wednesday that specific user account credentials were targeted.

Targets included government officials from the U.S. and "several Asian countries" as well as political activists, journalists, and military personnel, Google said.

"The goal of this effort seems to have been to monitor the contents of these users' e-mails, with the perpetrators apparently using stolen passwords to change peoples' forwarding and delegation settings,"

"It's important to stress that our internal systems have not been affected--these account hijackings were not the result of a security problem with Gmail itself. But we believe that being open about these security issues helps users better protect their information online," Grosse continued.

Google says it's notified those with affected accounts and has also secured the accounts. The company is encouraging users to add extra layers of security including designing more complex passwords, turning on two-step account verification, and only going through the company's secured "https://www.google.com" domain when logging on from a Web browser.

Google's blog post notes that "internal systems have not been affected—these account hijackings were not the result of a security problem with Gmail itself."

White Hat Hackers Find Skype Security Hole For Mac

Image representing Skype as depicted in CrunchBase



Skype has issued an update for all Mac users, due to security concerns in Skype version 5.x for Mac which allows a malicious user to activate code on the victim’s computer.

A security researcher said today that he found a serious hole in the Mac version of Skype and proving that it was possible to send a specific message to a user of Skype and it would crash Skype and make it unusable.

Gordon Maddern, says he discovered the vulnerability about a month ago. He was chatting on Skype to a colleague about a payload when the payload executed in the colleague's Skype client accidentally.

He created a proof of concept that can be used in an attack but is not releasing details on it until Skype fixes the issue. He could not find the vulnerability in the Skype client for Windows and Linux, he said.

Possible Security Breach At LastPass

Image representing LastPass as depicted in Cru...Users who manage and store their passwords through password management service LastPass are being forced to change their master passwords after the site noticed an issue this week that raised the spectre of a possible security breach.

LastPass wrote on their blog yesterday that because they can't account for the anomaly they detected in one of the databases, the company made the decision to assume the worst that some of its data had been hacked, even though they say you shouldn't be impacted by this issue if you have a strong, non-dictionary-based password.

LastPass hasn't identified a specific breach, it's erring on the site of caution by now forcing its members to change their master passwords.

LastPass let users create and manage passwords to more easily log in to the vast array of secure Web sites they visit.
Those passwords can be stored on a PC or mobile device as well as online. As one means of protection, LastPass typically urge users to create a single complex master password that can unlock the key to accessing their passwords.
Of course, if that master password is compromised, hackers potentially can gain access to all the individual passwords, one reason why these companies advise users to employ complex master passwords.

In the meantime, LastPass have moved services to other servers for now. They also compared the code on the live servers with code from their repositories to make sure it was not tampered with.
The company is also enhancing the encryption used to protect its data.
