Some security information updates

LinkedIn warns of 'Sell Hack' browser plugin

LinkedIn warns of a browser extension called 'Sell Hack' that claims to reveal hidden email addresses.

It initially gives the impression that it allows anyone to visit a LinkedIn profile page and 'hack' into LinkedIn’s systems to extract the page owner’s (normally private and hidden) email address.

However, what isn’t entirely clear is just how 'Sell Hack' is determining the email addresses it (sometimes) displays. One worrying scenario would be if the 'Sell Hack' tool itself were harvesting users’ accounts for contact information, and building up parts of its database that way.

Even after you’ve used 'Sell Hack', the extension is able to watch your activity on the site and collect the information of any direct connection whose page you’ve decided to visit. What it’s using this information for is unclear.

Installing dubious browser plugins is a dangerous game, that could result in your personal, private information being compromised.

Important update for Safari browser

The update incorporates a series of security fixes that patch over 25 vulnerabilities. The vulnerabilities relate to WebKit, the web-rendering engine that sits at the heart of the Apple Safari browser, and the basis for the Blink engine fork used by rival browser Google Chrome.

Mac users could find themselves unwittingly and unknowingly running malicious code (such as Trojan horse) on their computers just by visiting a boobytrapped website.

Apple recommends that Mac OS X users update to Safari 7.03 or Safari 6.1.3 as soon as possible to patch the security flaws.

The update can be downloaded and installed using Software Update:

Google switches Gmail to HTTPS only

Gmail will use an encrypted HTTPS connection to check or send email, regardless of what platform users employ to access the service – and there is no longer an opt-out for Gmail users to use a less secure connection instead.

Google also announced that all emails will be encrypted while moving internally between Google’s data centres.

Vulnerability in Microsoft Word Could Allow Remote Code Execution

The vulnerability could allow remote code execution if a user opens a specially crafted RTF (rich text format) file using an affected version of Microsoft Word, or previews or opens a specially crafted RTF email message in Microsoft Outlook while using Microsoft Word as the email viewer. An attacker who successfully exploited the vulnerability could gain the same user rights as the current user.

Microsoft said the exploits it has seen so far attacking this vulnerability have targeted Word 2010 users, but according to Microsoft’s advisory the flaw is also present in Word 2003, 2007, 2013, Word Viewer and Office for Mac 2011.

Users whose accounts are configured to have fewer user rights on the system could be less impacted than those who operate with administrative user rights.

Microsoft says it’s working on an official fix for the flaw, but that in the meantime affected users can apply the Microsoft Fix it solution, "Disable opening RTF content in Microsoft Word" - https://support.microsoft.com/kb/2953095 to prevent the exploitation of this issue through Microsoft Word.

One way to harden your email client is to render emails in plain text.

For more information on how to do that with Microsoft Outlook 2003, 2007, 2010 and 2013, check out the following Microsoft knowledgebase articles:

1) Office 2003, 2007 and 2010 - http://support.microsoft.com/kb/831607

2) Office 2013 - http://office.microsoft.com/en-us/ou...102748923.aspx

Re: Some security information updates

Thanks Wally.

Why does using the Internet have to be like a minefield combined with an assault course? There are some brilliant criminal minds out there, if only they would use their skills for the good of Mankind.

Sadly John Mankind can be too greedy to even consider that suggestion you made as a worthwhile proposition.
