Webcam blackmail threat

I recently received an email containing a password which I had used some time back to access a website. This was certainly interesting.

It then went on to say that I had visited their porn site and that as a result my computer was infected with a virus and that said virus had recorded me getting up to no good through my webcam!

The price of silence was around £1,000 payable by Bitcoin not to release the resultant video nor publish my browsing history.

Well, it's all a scam but how was my password acquired?

Was I hacked? Highly unlikely given the security on my network.

Even if a virus had slipped under the radar, saved passwords are encrypted on a PC and not easy to extract.

I concluded that a website upon which I had registered had been hacked and my email address and password thus acquired. This would indicate some laxity by the website which should never have stored the password explicitly.

Folks who use the same password for multiple sites or for their Windows or email login are the ones most likely to be tricked by this.

If you do receive one of these then ignore it. You have not been hacked but might want to think about whether you use the same password for more than one website.

.uk domain offers

Customers of 123-Reg who have .co.uk domains may receive an email confusingly asking to activate said .co.uk domain.

This is either a bug or a bit of blatant marketing. Given 123's past mixups with mail such as sending out renewal reminders without actually specifying the domain name then I suspect the former.

Anyway, what they are offering is a year free with the corresponding .uk domain - your existing domain minus the ".co" bit. After that you pay annually.

It's generally not worth doing unless you want to keep the .uk out of the hands of anybody else.

Apart from that it's just an annoying sale gimmick.

Android ... is busy (when moving or copying a file)

Problem arose on my phone when connected via USB and trying to move files around using Explorer.

I got the message "Moto 3 is busy".

Similar messages anecdotally reported for other phone.

To solve the problem, find the Developer section in the (phone) settings and enable USB Debugging. This, for some reason, this can fix the problem but this is not assured.

Runsw.exe and runswusb - high page faults / memory useage.

Runswusb is the service, runsw.exe is the program.

Spotted this on a 4gb Win 7 system with a Page Fault delta of 1,000+

Stopped and disabled the service. No side effects noted.

Google Calendar notifications - turn sound off/on

There is no obvious way to turn off the sound on Google Calendar notifications.

Hitting the cog on the notification itself leads nowhere.

To solve:

Go to calendar.google.com

Find the calendar on the list.

Hover over it to get the three dots

Click the dots then Settings and Sharings

then

General

and toggle the Play Notification Sounds box

Mac and External drives

I wanted to use a USB disk for a Mac backup.

Plugged the disk in and found that it was 'read only'.

I plugged the disk back into my Windows PC and created an ExFat partition.

On plugging back into the Mac it was able to write to the new partition.
