Security Vulnerability In Mail-to-Blogger Passwords

In early 2010, Blogger issued a typically terse warning of a security problem, with blogs that use Mail-to-Blogger for publishing posts.
To prevent abuse, a recent update to disabled easily guessable secret words. Please update your Mail2Blogger secret word.

I've referred to the importance of the "secret word" some time ago - and apparently this year, a few blogs are being hit by the vulnerability.

If you are using Mail-to-Blogger for publishing - and especially if you enabled "Publish emails immediately" - this is a change which you need to make.

There is an organised attack technique, where blogs, owned by accounts with weak "passwords", are being used as spam hosts. In some cases, this results in splog detection, with the well known and hated in forum triage being required, to get the blog unlocked - then cleaned.

If you are inadvertently using an author account, instead of your owner account, you may have enabled Mail-to-Blogger, while trying to recover control of the blog. Whether accidentally or intentionally, your blog is now vulnerable.

If your blog uses Mail-to-Blogger (Settings - "Mobile and email" - "Posting using email"), and you have selected "Publish emails immediately", please change your Mail-to-Blogger password, to something not easily guessable - but reliable. If you don't need to post using email, select "Disabled".

Just please - do this before you have to post, following organised brute force hacking, in Blogger Help Forum: Something Is Broken
Please, help me! My blog is locked!!

Hi Habibu,

Thanks for the question.

The "Disabled" selection, for "Posting using email" will disable M2B, and make your blog safer. Or you can make the "password" a bit harder to guess, if you really want to post by email.

Stats Components Are Significant, In Their Own Context

One popular Stats related accessory, which displays pageview information to the public, is the "Popular Posts" gadget.

Popular Posts identifies from 1 to 10 of the most popular posts in the blog, by comparing Stats pageview counts. Optional parts of the display of each post are a snippet of text, and an ever popular thumbnail photo.

Like many Stats features, blog owners have found imaginative uses for "Popular Posts" - and overlook the limitations of the gadget. Both the dynamic nature of Stats, and the timing of the various pageview count recalculations, create confusion, when Popular Posts is examined.

Free Domain Registration By "UNONIC" Is Fraudulent

Blogger blog owners, like everybody else, like to save money.

Some blog owners prefer to save money when registering a custom domain, for their blogs. We've seen several free domain registration services, providing what is claimed to be a two level Top Level Domain "co.xx" (where "xx" == various country codes).

The latest in this ongoing story appears to be "net.tf" - and 13 other "top level domains".There is also an additional free service offering third-level .tf domains, under the name United Names Organisation. They occupy 14 second-level domains, including .eu.tf, .us.tf, .net.tf, and .edu.tf. They are run by the same company as smartdots.com, and are given away as URL redirections.
