My latest hobby is...

... trashing my tyres.

Or at least somebody at Asda seems to think it is. I replaced one about six months ago. I used an online service which I assume must have been Asda to get one from a local garage. Since then not a week goes by without an email arriving telling me of their latest bargains. Nearly as bad as every visit to Amazon assuming I wish to add to a collection of coffee machines and collections of most other items I've ever looked at or bought on their website.

Other retailers all seem to think that I'm just gagging to write reviews about everything I buy from a box of screws from Toolstation to an SD card I wanted quick so bought from Argos. I did used to answer some product queries for Argos items until I got sick of their damned site insisting I turn off my ad blocker when submitting them and commented on it in an answer. Rather than edit that out they told me my reply did not meet their guidelines so that was the end of that for me.

The downside of buying online!  Particularly annoying for me when its a present I've bought for someone who lives elsewhere, like family in Scotland! I might never even see it.

 heaven knows where this all came from...

Hackers break the sites of many companies and harvest user data. This will almost always include emails and can sometimes even include passwords. I was annoyed when I found a website hosting company I had briefly used had been hacked and had stored the password I was using there in plain text. Idiots. It was an easy to remember one I used in lots of places where I wasn't fussed about the account security. I still get emails addressed with "Hi [my hacked password]"

Mine has many times. I use gmail though and their spam filter is excellent with virtually none getting through..

The data contained almost 2.7 billion records including 773 million unique email addresses alongside passwords those addresses had used on other breached services. Full details on the incident and how to search the breached passwords are provided in the blog post The 773 Million Record "Collection #1" Data Breach.

Exploit.In logo
Exploit.In (unverified): In late 2016, a huge list of email address and password pairs appeared in a "combo list" referred to as "Exploit.In". The list contained 593 million unique email addresses, many with multiple different passwords hacked from various online systems. The list was broadly circulated and used for "credential stuffing", that is attackers employ it in an attempt to identify other online systems where the account owner had reused their password. For detailed background on this incident, read Password reuse, credential stuffing and another billion records in Have I Been Pwned.

In 2019, the data appeared listed for sale on a dark web marketplace (along with several other large breaches) and subsequently began circulating more broadly. The data was provided to HIBP by a source who requested it to be attributed to "[email protected]".

In total, there were 711 million unique email addresses, many of which were also accompanied by corresponding passwords. A full write-up on what data was found is in the blog post titled Inside the Massive 711 Million Record Onliner Spambot Dump.
