The CAPTCHA Continues As A Challenge

This month, we are again seeing evidence of recent security changes by Microsoft. We see signs of continued frustration, in the process of publishing comments - and publishing posts, as part of the Import process.

In the process of diagnosing an apparent comment publishing problem, I ventured into the comment publishing experience, yet again.

I temporarily tweaked commenting permissions for this blog, to allow anonymous comments and to require the CAPTCHA.

With CAPTCHA required, I published a test comment to my earlier post in this blog.

I did my best - which was not good enough.



CAPTCHA solving continues, as a challenge.

I entered a test comment, and made appropriate selections.

I got a challenge.

"Select all the food."

I did my best.

Apparently, my best was not enough.

"Select all images with a store front."

I tried again. Not all images here were completely obvious, either.

My second try was successful.



Hmm.

Select all the food.

Zoom in on the fourth image, above - and tell me which pictures, that I did not select, are food? To whom? Will zooming always improve chances of success?

CAPTCHA solving, as spam interdiction, will always lead to frustration.

There will be cultural issues - and resolution problems - with CAPTCHAs. This version of the CAPTCHA beats the one from several years ago - but still will cause frustration.

And need I again point out - will require proper filter tuning, on each computer used. Note that ongoing changes by Microsoft are currently affecting publishing comments - and publishing posts during the Import process.

And our experience may very, depending upon many different details, varying by blog, by computer, and by person. My sympathies to all who must deal with spam - and with spam interdiction.

The CAPTCHA continues to be an unavoidable element in comment publishing and other episodes of #Blogger life. And like life, some episodes are more pleasant than others.

"Nice Blog" Spam Is Recently Becoming More Obscure, In Content And Style

In 2009, we discovered an odd style of spam comments which, from all appearances, served no purpose.

I recently came across your blog, and have been reading along. I thought I would leave my first comment. I don't know what to say except that I have enjoyed reading. Nice blog. I will keep visiting this blog very often.

When discovered, Google Search suggested that over 22,000,000 copies of these comments had been successfully installed, on various blogs and websites.

A couple years ago, I suggested a possible reason for the spam - and later showed how Google+, and various Blogger security measures, were making the spam less useful.

Last month, we began to see suggestions, from some blog owners, that this "nice blog" spam was morphing, into more obscurely phrased and structured styles.

A lot of spam comments are being published on my blog. This problem started a few weeks ago - though previously, Google almost always put them in my Spam Folder.

Upon examination of examples of the spam comments, we see the same spam style as observed in 2009 - yet more imaginatively phrased.

Today, I spent a couple hours, and scanned through the comments queues on this blog. Both the Awaiting, and Spam, folders yielded some interesting specimens.

This topic is very educational and it took my interest. Hope it will always be alive! And provide productive information to many others.

and

Nice post. I learn something new and challenging on websites I stumble upon every day. It's always interesting to read articles from other writers and practice a little something from other sites.

These were the comment bodies of just two examples which I located - and these resemble others identified by various other blog owners.

The bodies of the comments examined, this week, will sometimes contain embedded links, while other examples will have external links - and some comments seem to contain no links at all, to any payload. The only thing consistent about the comments is their vague and apparently pointless nature.

The comments are both large in volume, and varied in content and structure. Both patience and persistence, from every blog owner moderating the spam, is required. The spam filters must be trained, to recognise the new content and structures - and this will require more effort, from everybody seeing the spam.

Since various reports about the spam have been seen recently, in Blogger Help Forum: Something Is Broken, we added a rollup discussion there, where we are requesting minimally organised details about the comments being observed.

• Are you moderating before, or after publishing?
• What's the average amount of time the spam comment sits in "Awaiting" or "Published", before being moved to "Spam"?
• How often do you check "Awaiting" and "Published", looking for more spam comments?
• How often do you check "Spam", looking for non spam comments?
• How many spam comments do you typically dispatch, in each batch?
• Looking objectively in your personal "Awaiting", "Published", and "Spam" folders, what number of this style of comments do you typically see in each, without your intervention?
• When did you first observe this threat, in your comment folders?

As always, please help here by answering as carefully and completely as possible - and please only post relevant replies. Do not turn the rollup discussion into a chat room.

Use Of Google+ For Networking, And Keeping Your Blogger Account And Blogs Safe

One constant activity in Blogger Help Forum: Something Is Broken involves blog owners whose blogs were deleted - either righteously or spuriously - as part of the ongoing battle against spam, in Blogger blogs. Generally, the problem comes directly from the blog content.

Sometimes, the problem is more subtle.

When I tried to login to Blogger, I got a screen that said my account needed to be verified, due to "unusual activity on my account". Having verified my account, I see that my blogs have been deleted.

This is part of one of the more intriguing episodes, in the never ending fight against hacking and spam, in Blogger.

Some Blogger blog owners participate in comment based discussions, and provide their email addresses there. Some state their email addresses openly, in the body of the comments, for the world to see when viewing the comments. Others post comments using their Blogger accounts, knowing that the blog owners can see their email address in the comment moderation / notification email messages - and can contact them using email.

Spammers use comment based networking, to their advantage. They subscribe to any comment thread, using the "Notify me" option - then wait while blog readers comment using their Blogger accounts. As the email comes in, from blog readers commenting, they scrape the email addresses from the email content. Since most people commenting either openly state their blog URLs in the comment bodies - or link to a list of their blogs - the spammer now has two essential ingredients, to be used for hacking someone's Blogger account, and gaining control of the blogs owned by the account.

Google now provides Google+, where we can network with a designated audience, and avoid spam in our email. Using Google+, our email addresses are not revealed, and spammers have less incentive to use Google+ for email address harvesting. This protects our Blogger accounts and blogs against hacking, and relieves us from email based spam.

For people who update their Blogger accounts to use Google+ based profiles, but continue to network using Blogger comments, Blogger now protects us by using anonymous email addresses in all comment generated email. This leaves people who continue to comment, using Blogger accounts with native Blogger profiles, vulnerable to ongoing email address harvesting, and account hacking.

Blogger account hacking, using email addresses harvested from Blogger blog comments, will typically involve brute force password guessing. Blogger, detecting brute force attempts against a vulnerable Blogger account, will lock the account and the blogs. Once we verify ownership of our Blogger account - and hopefully change the Blogger account password to something less vulnerable to guessing - the blogs owned by a possibly compromised account remain locked, until they can be examined for signs of tampering, by Google security / spam analysts.

We also must consider the possibility that not all brute force password guessing attacks are being detected by Google - and some Blogger accounts are being deviously, and temporarily, hijacked.

People who setup Blogger accounts based on bogus email addresses - or who have accounts based on old email addresses which they can't use - continue to present a challenge here. These people will never receive essential email advising them of a problem in either verifying their Blogger account - or their blogs. This will continue to make our initial spam lock advice relevant.

Can you login to Blogger? Do you have a dashboard link "Deleted blogs"? That's where you start.

You wait 24 to 48 hours after submitting a Restore request - then you post back here, and we take the next step.

Blogger Comments Being Posted Using Anonymity

Some Blogger blog owners use their Blogger blogs as the center of their peer to peer networking life.

Many blog readers are expected to post comments - and to leave their email addresses, as part of their message or profile, to allow direct contact. Long ago, I used the email address of my commenters, as part of an easy "Contact Me" form, on this blog.

Recently, we've been noting that Blogger comments don't always include a useful email addresses - many comments simply describe the commenter as

noreply-comment@blogger.com

Not all blog owners - and readers - appreciate this change.

When I leave a comment using my google profile, it isn't linking my profile with my email address. How do I get my email address properly displayed?

and

Why do so many comments, published to my blog, show the email address of "noreply-comment@blogger.com"? How do I email my readers?

For some time, we've known of the dangers of revealing your email address to the world, in general.

Blogger blog owners have been a known special risk, with their email addresses. Google developed Google+, with the Google+ profile, to allow everybody to network with their friends - both old and new - without the risk of revealing one's email address.

Google+ replaces email completely. You can share comments, messages, photos, and videos with anybody, in a self contained universe - and you can define your own, personal universes. This leaves the need to reveal your email address completely unnecessary (though you can use email, if you wish, without knowing anyone's address - or revealing yours).

After Google+ became popular, Blogger added the option to link our Blogger blogs with our Google+ profiles. Blogger profiles, based on Google+, are cleaner, and use the Google+ displays to update.

To encourage people to use Google+ for peer to peer networking activity, and to make our Blogger accounts and blogs safer, Blogger has eliminated our email addresses from all outside correspondence - including when we publish comments on Blogger (and non Blogger) blogs, using a Google+ based Blogger profile.

If we publish a comment on somebody's blog, and the blog owner has enabled comment moderation or notification, our comment shows up in the email inbox of the blog owner - but with our email address displayed as "noreply-comment@blogger.com".

With email addresses not displayed, this helps protect our Blogger account names from becoming unnecessarily revealed. Blog owner - reader comment communication is still possible - but again, without the email address of the reader being known.

By eliminating our email addresses from our comments, Google is helping to protect our accounts and blogs, while letting us continue to comment on each others blogs - and to eliminate one type of unnecessary spam from our blogs.

Google+, which replaces email for networking, uses a "Friend of a Friend" relationship to let you expand your universe infinitely, with each comment, message, photo, and video that you share. It lets you control the expansion of your universe - if you wish. And, it helps keeps your Blogger blog under your control.
