2022-08-11 The summer bitcoin extortion scam
Cybercriminal Summertime is also time for some extortion scamming... this one just in:
Hi. How are you?

I know, it’s unpleasant to start the conversation with bad news, but I have no choice.
Few months ago, I have gained access to your devices that used by you for internet browsing.
Afterwards, I could track down all your internet activities.

Here is the history of how it could become possible:
At first, I purchased from hackers the access to multiple email accounts (nowadays, it is a really simple thing to do online).
As result, I could easily log in to your email account

One week later, I installed Trojan virus in Operating Systems of all devices of yours, which you use to open email.
Frankly speaking, it was rather straightforward (since you were opening the links from your inbox emails).
Everything ingenious is quite simple. (o_0)!

..

Here is my bitcoin wallet provided below: bc1q82tvkvmzjzyqf60guqpxhcn2tuapqup35a9ldr

You should complete the abovementioned transfer within 48 hours (2 days) after opening this email.

The following list contains actions you should avoid attempting:
#Do not try calling police as well as other security forces. In addition, abstain from sharing this story with your friends.
After I find out (be sure, I can easily do that, given that I keep complete control of all your devices) – your kinky video will end up being available to public right away.
#Do not try searching for me – there is absolutely no reason to do that. Moreover, all transactions in cryptocurrency are always anonymous.
#Do not try reinstalling the OS on your devices or throwing them away. It is pointless as well, since all your videos have already been uploaded to remote servers.
As always: don't fall for these scams.

2022-08-06 PGP key needs fetching from time to time
PGP lock logo Someone reported to me my PGP key was expired and whether I was still using it or I gave up on PGP/GPG.

I have an expiry date on my key, but I do update it from time to time when expiry nears. I now notice just doing a gpg --refresh doesn't update the expiry moment. The solution is to hard fetch the key. In the case of my home pgp key:
$ gpg --keyserver pgp.surf.nl --receive-keys 0x5BA9368BE6F334E4
This updates the expiry date(s) and the uids. If you have my key and it looks expired and/or still has an old e-mail address with kzdoos in it please do this now. Complete data at pgp.surf.nl: Search results for '0x5BA9368BE6F334E4' where you can see all the details including the revoked bits. Those revoked bits won't show up in normal use.

I know gpg and other pgp related software has to be designed to be really really secure up to the last bit, but some attention to user friendlyness could be a good idea if it's possible to confuse even experienced pgp users.
