Should I consider a service that scans the dark web for my personal information?

A service being offered by various security companies is a “dark web scan,” which sounds pretty impressive based on the name.

The dark web is where lots of cyber-criminals conduct business, so logically, monitoring the activity in the underworld makes sense. But, it’s important to understand the limitations.

What is the “dark web”?
If you think of the internet as an iceberg, the part that we interact with is the portion above the waterline, which is indexed by search engines such as Google and Bing.

Curious about the ‘deep web’? Here’s what you should know
CYBER SECURITY NEWS
A much larger part of the internet is actually below the waterline in what is known as the deep web or the portions of the internet that cannot be indexed by search engines.

The deep web is where private databases exist, along with all the protected information that is behind subscription walls or secured logins for private industry, government entities and academic networks just to name a few.

A small portion of the deep web is known as the dark web because it’s primarily known as the place to go if you want to engage in illicit activities.

It’s not indexed
Unlike the internet that you’re using every day, the dark web is not indexed, so there is no way to find things unless you know exactly where to look.

The notion of “scanning” the dark web in the way most people would envision the process is actually impossible, because without an index, there’s nothing to scan. What these services are offering to do is “monitor” the small portion of the dark web that are known as “bazaars” or “marketplaces,” but only the ones that they know about.

The real heavy criminal activity often exists in hidden and very hard to join private networks in which users are scrutinized extensively before they’re allowed in.

Most estimates are that commercial “dark web scan” services only know about your information in a small fraction of the actual underworld’s activity.

A better approach
If you think about it, you’d be paying these companies to tell you whether your personal information is floating around in the underworld, and if so, you’d respond accordingly.

You would likely change your passwords and make them stronger, close accounts that you’re no longer using and start monitoring your credit file regularly.

My suggestion is that you should just assume that your personal information is being traded on the dark web and act accordingly.

With all of the major breaches of sensitive information over the past decade, it’s almost a certainty that your sensitive personal information exists in one or many underworld databases.

Remember: Security companies generally are using the dark web scan to convince you to pay for some form of adjunct service such as ID theft protection.

The best defensive step you can take against ID thieves is to freeze your credit report, which prevents anyone from accessing your credit file. If you’re actively applying for loans, you’ll want to wait until your applications have all been approved and place a fraud alert on your file instead.

Fraud alerts need to be renewed every 90 days, and you’ll want to do so with all three of the major credit bureaus (Experian, Equifax and TransUnion).

UPDATED NOTICE OF DATA BREACH

Dear Yahoo User,

We are writing to update you about a data security issue Yahoo previously announced in December 2016. Yahoo already took certain actions in 2016, described below, to help secure your account in connection with this issue.

What Happened?

On December 14, 2016, Yahoo announced that, based on its analysis of data files provided by law enforcement, the company believed that an unauthorized party stole data associated with certain user accounts in August 2013. Yahoo notified the users it had identified at that time as potentially affected. We recently obtained additional information and, after analyzing it with the assistance of outside forensic experts, we have determined that your user account information also was likely affected.

What Information Was Involved?

The stolen user account information may have included names, email addresses, telephone numbers, dates of birth, hashed passwords (using MD5) and, in some cases, encrypted or unencrypted security questions and answers. Not all of these data elements may have been present for your account. The investigation indicates that the information that was stolen did not include passwords in clear text, payment card data, or bank account information. Payment card data and bank account information are not stored in the system we believe was affected.

What We Are Doing

In connection with the December 2016 announcement, Yahoo took action to protect users (including you) beyond those identified at that time as potentially affected. Specifically:

Yahoo required potentially affected users to change their passwords.

Yahoo also required all other users who had not changed their passwords since the time of the theft to do so.

Yahoo invalidated unencrypted security questions and answers so they cannot be used to access an account.

We are closely coordinating with law enforcement on this matter, and continue to enhance our systems that detect and prevent unauthorized access to user accounts.

What You Can Do

While Yahoo already has taken action to help secure your account, we encourage you to consider the following account security recommendations:

Change your passwords and security questions and answers for any other accounts on which you used the same or similar information used for your Yahoo account.

Review your accounts for suspicious activity.

Be cautious of any unsolicited communications that ask for your personal information or refer you to a web page asking for personal information.

Avoid clicking on links or downloading attachments from suspicious emails.

Additionally, please consider using Yahoo Account Key, a simple authentication tool that eliminates the need to use a password on Yahoo altogether.

For More Information

For more information about this issue and our security resources, please visit the Yahoo 2013 Account Security Update FAQs page available at https://yahoo.com/security-update.

We value the trust our users place in us, and the security of our users remains a top priority.

Sincerely,
Chris Nims
Chief Information Security Officer
