ClearCloud DNS Service Bites The Dust – Pick Up The Slack With Norton DNS

Occasionally, when I’m stuck for time, I’ll post an edited version of an earlier article. In choosing an appropriate article, I try to focus on a free application or service that has real value, but is often underappreciated. More and more often though, I’m finding that a free application I reviewed is no longer free, or the free service I recommended, no longer exists.

Another one bites the dust.

Regular reader Georg L., has just notified me that ClearCloud DNS, a free DNS alternative (reviewed here September 5, 2010) which prevented users from visiting sites identified as harboring malware exploits, will be closing the curtain – effective September 1, 2011.

If you are currently using ClearCloud DNS, you will need to reconfigure your network connection prior to September 1, so that your Internet connectivity is not interrupted. You can learn how to remove ClearCloud DNS from your computer by clicking here.

If you’re convinced that an alternative DNS service has value, and you wish to continue to harden your system by substituting your ISP provided DNS service, with a more secure alternative – you have a number of choices to consider, including – Norton DNS, with Norton Safe Web.

Benefits of running with Norton DNS:

Malware Site Blocking – Automatically blocks known dangerous and infected Web sites. Provides a complete overview of the threats found so you know why a site is blocked.

Web Content Filtering – Lets you block Web sites that contain content that you think is inappropriate or dangerous. You can choose from over 45 different categories of content to block and specify individual sites to block.

Here’s an example of Norton DNS in action following my clicking on a spam comment link.

Further investigation of the Threat Report, reveals the following.

Pretty scary stuff, I think you’ll agree.

You can install Norton DNS either by download and running the installer or, if you want to have a bit of fun – you can choose to install manually. At first glance, you may think this is complicated when it fact, it’s quite easy. So, give it a try, and don’t be nervous.  :)

Fake URL Shortening Services –Spammers Latest Weapon

imageAccording to Symantec’s May 2011 MessageLabs Intelligence Report, released several days ago, spammers are now employing their own fake URL shortening services to redirect users to the spammer’s Web site. It’s hardly surprising that this new technique has directly contributed to rising spam rates.

MessageLabs Intelligence reports that “shortened links created on these fake URL-shortening sites are not included directly in spam messages. Instead, the spam emails contain shortened URLs created on legitimate URL-shortening sites. These shortened URLs lead to a shortened-URL on the spammer’s fake URL-shortening Web site, which in turn redirects to the spammer’s own Web site.”

Key findings from the May 2011 report include:

Spam: In May 2011, the global ratio of spam in email traffic from new and previously unknown bad sources increased by 2.9 percentage points since April 2011 to 75.8% (1 in 1.32 emails).

In the US 76.4 percent of email was spam, 75.3 percent in Canada, 75.4 percent in the UK, and 73.9 percent in Australia.

Viruses: The global ratio of email-borne viruses in email traffic from new and previously unknown bad sources was one in 222.3 emails (0.450 percent) in May, a decrease of 0.143 percentage points since April.

Endpoint Threats: The most frequently blocked malware targeting endpoint devices for the last month was the W32.Ramnit!html, a worm that spreads through removable drives and by infecting executable files.

Phishing: In May, phishing activity was 1 in 286.7 emails (0.349 percent), a decrease of 0.06 percentage points since April.

Web security: Analysis of Web security activity shows that approximately 3,142 Web sites each day were harboring malware and other potentially unwanted programs including spyware and adware, an increase of 30.4 percent since April 2011. 36.8 percent of malicious domains blocked were new in May, an increase of 3.8 percentage points since April. Additionally, 24.6 percent of all web-based malware blocked was new in May, an increase of 2.1 percentage points since last month.

The May 2011 MessageLabs Intelligence Report provides greater detail on all of the trends and figures noted above, as well as more detailed geographical and vertical trends. The full report is available here.

Reading this type of report (or at least the highlights), can be a major step in expanding the sense of threat awareness that active Internet users’ require.

Symantec’s MessageLabs Intelligence is a respected source of data and analysis for messaging security issues, trends and statistics. MessageLabs Intelligence provides a range of information on global security threats based on live data feeds from control towers around the world scanning billions of messages each week.

Steer Clear of Malware Web Sites With ClearCloud DNS

imageSecurity conscious Internet users are aware, that so called “trusted” websites, are not always to be trusted. We’ve covered this issue here on Tech Thoughts a number of times, most recently in, “How Safe Are Trusted Web Sites? Not Very!

The following is a brief explanation, from that article, on how cyber crooks manage to infect web sites:

“Cyber-crooks can exploit vulnerabilities on the server hosting the web page to insert an iFrame, (an HTML element which makes it possible to embed another HTML document inside the main document). The iFrame can then activate the download of malicious code by exploiting additional vulnerabilities on the visiting machine”.

Unfortunately, installed anti-malware solutions may not always provide adequate protection against this type of attack. Luckily, there is a solution which can add an additional layer of security by substituting your ISP provided DNS service, with a more secure alternative. An alternative that can prevent you from visiting sites that harbor malware exploits.

Free alternatives include OpenDNS, Google DNS, Norton DNS – and now, an additional free service can be added to this list with the release of ClearCloud Beta from Sunbelt Software, the developer’s of the highly regarded VIPRE antivirus application.

According to ClearCloud, the application “checks every website address your computer is trying to access, whether you’re browsing the internet, clicking a link in an email, or a program “under the hood” trying to communicate with servers for information or updates”.

In a quick 24 hour test, I found ClearCloud worked as advertised. With ClearCloud up and running, you will be prevented from visiting sites identified as harboring exploits. In which case, you will get detailed information on why ClearCloud believes the site is unsafe.

Taking advantage of this service couldn’t be easier. Simply download the setup application, execute, and as the simply interface shown below indicates, you’re now protected by ClearCloud.

Following installation, visit the ClearCloud block page to verify the service is up and running.

System requirements: Windows, Mac.

Download at: ClearCloud

Alternatively, you can manually set your DNS server address to 74.118.212.1.

Note: You can configure ClearCloud on your router. Click here for a setup walkthrough.

A big ”Thank You” to regular reader TeX for bringing this service to my attention.

Norton DNS Can Save Your Butt!

In early June, I posted an article – Norton DNS – Another Layer of Computer Security, in which I stated –

You should consider additional system hardening by substituting your ISP provided DNS service, with a more secure alternative.

A few days later, I posted an article – Follow the Link and You “Takes Your Chances”, in which I made the point –

As a matter of policy, I test every allowed link included in a comment, for safety. Spam filters can often miss comment spam, some of which are highly dangerous. While comment Spam is a pain for the Blogger, a reader who follows a link in a malicious Blog comment, which leads to a malware site, is in for a very painful experience.

The following comment emailed to me by WordPress just today, and not picked up by the Askimet spam filter, provides a perfect example where these two intersect:

The email notice:

A new comment on the post “Download TrueCrypt –  TrueCrypt Beats The FBI Decryption Team!” is waiting for your approval.

Author : retnol (IP: 202.70.54.67 , 202.70.54.67)

E-mail : retno.larasati08@student.ipb.ac.id

URL    : http://retno.larasati08.student.ipb.ac.id

Comment:

well, nice post. Thank you for sharing.

Approve it:

Trash it:

Spam it:

On testing the URL (the link), contained in the comment, I get this result from Norton DNS. This is not as uncommon as you might think.

image

Further investigation of the Threat Report, reveals the following.

image

Pretty scary stuff, I think you’ll agree.

So, I’ll repeat –

Be cautious when following links contained in comments on any web site – not just Blogs.

Be particularly cautious of comments, on any web site, where the writer is describing a problem with recommended software and offers a link to alternative software.  This is a favorite technique employed by cyber-criminals. All software reviewed on this site, for example, has been thoroughly tested, by me, for usability. If a reader has a problem with recommended software, it’s generally a machine specific problem.

Be cautious when following any link contained in any web page. Recent reports indicate there are 5.8 million individual web pages infected across 640,000 compromised websites. Cyber-criminals are finding it easier than ever to inject malicious content into legitimate sites.

Since the majority of infected sites are infected with Java based scripts, consider using Firefox with the NoScript add-on. NoScript offers superior protection.

Install an Internet Browser add-on that provides protection against questionable, or unsafe websites.

Use Norton DNS as an added safety precaution.

You simply cannot trust links, given the state of the Internet, so if you haven’t hardened your system by substituting your ISP provided DNS service, with a more secure alternative, I urge you to do so.

I deal with comments like this every day – it just happens, that today, I had some spare time to bring this situation to your attention, one more time.

Free alternatives include OpenDNS, Google DNS, and now Norton DNS – a free service (in Beta), that provides faster web browsing with basic security. The additional security is provided by Norton Safe Web, which provides a quick check on each site to make sure that it isn’t a threat. If it is, you are protected from the site, and you will get detailed information on why Norton believes the site is unsafe.

Norton DNS, with Norton Safe Web incorporated, prevents users from visiting sites identified as harboring exploits including.

How to Protect Your Child on the Internet

Instant Messanger changed There is little doubt that the Internet neighborhood can provide a rich educational and cultural experience for children of all ages and backgrounds.

But, would you drop your child off in a neighborhood where more than half of the buildings were adult stores, and was potentially full of predators? Well of course you wouldn’t.

If you let your child explore the Internet unsupervised, or without having communicated to your child information about potential on-line dangers, this is close to what you’re doing.

According to the FBI in the United States, the following are some of the most important positive actions, you as a parent can take, to enhance your child’s safety on the Internet.

Communicate, and talk to your child about potential on-line dangers.

Spend time with your children on-line. Have them teach you about their favorite on-line destinations.

Keep the computer in a common room in the house, not in your child’s bedroom.

Utilize parental controls provided by your service provider and/or blocking software.

Parental Control Bar 2

Since computer-sex offenders are a very real danger on the Internet, the FBI suggests that you instruct your children to:

Never arrange a face-to-face meeting with someone they met on- line.

Never upload (post) pictures of themselves onto the Internet or an on-line service to people they do not personally know.

Never give out identifying information such as their name, home address, school name, or telephone number.

Never download pictures from an unknown source; there is a good chance there could be sexually explicit images.

Never respond to messages or bulletin board postings that are suggestive, obscene, belligerent, or harassing.

Parental Control Bar 4

An important aspect of ensuring that your child is safe while using the Internet, (recommended by the FBI and child safety experts/organizations), is the installation of parental control software. Parental controls will provide you with the advantage of being able to:

Block access to materials (text and pictures) identified as inappropriate for kids.

Permit access only to materials specifically approved as safe for kids.

Specify what types of materials are appropriate for your child.

Monitor your child’s activity on the Internet by storing names of sites and/or snapshots of material seen by your child on the computer for you to view later.

Set different restrictions for each family member.

Limit results of an Internet search to content appropriate for kids.

Enforce time limits set by parents.

A free solution, available as a download from the Internet is Parental Control Bar, a browser toolbar which works on the most popular Internet browsers.

Parental Control Bar is provided free of charge to the public by WRAAC.org, a non-profit organization dedicated to providing free, effective internet control tools.

Parental Control Bar Features:

Child/Parent Mode

This status indicator makes it easy to tell if your computer is in Child-Mode or Parent-Mode. When in Child-Mode, control features are enabled and web sites are blocked based on your parental settings. When in Parent-Mode, control features are disabled and you, the parent, have unrestricted access to the Internet.

Parental Password

A single password makes it easy for you, the parent, to enable or disable Child-Mode. There is a hint to help you remember your password, or if you forget it completely have it sent to a parental email address.

Help Menu

Clicking this button opens the toolbar menu where parents can access tutorials, help menus or change your password.

Change Parental Settings

Clicking this button opens the parental settings menu where you can specify the types of content you wish to block your family from accessing in Child-Mode. You can also manage your personal list of ‘blocked’ and ‘child-safe’ sites from this menu.
