Recent scam/phishing message(s)

17 May 2024 07:43:56 +0000

Please be advised that there is a phishing message getting through the spam filters with the subject:

Oops, Error updating the POP/IMAP server of YOUR-DOMAIN.TLD

In the actual email, “YOUR-DOMAIN.TLD” just happens to be the domain of the email address to which the scam was sent (see screenshot below). (What a coincidence!) These are not sent by NinerNet, as even a cursory look at the “From” field will show. We also do not use folksy words like “Oops” in business and technical emails, and we don’t pose as the “webmaster” of your domain. We are NinerNet, and that is how we always present ourselves to you, our client.

If you click the button to “Update Preferences” (or whatever action your copy of the message urges you to take) — which we strongly urge you not to do! — you will be taken to a page that looks like the log-in page for a webmail system (not our webmail system, I hasten to emphasise!), where the scammers expect that you will enter your email log-in information. Your log-in will fail, of course, but you will have given your real email password to the scammer, who will then use it to hijack your account.

If you or someone in your organisation falls for this, change the password for that account immediately! It’s not shameful to fall for a scam; many are convincing and we are all busy people who sometimes do something we regret when we are busy and distracted. What is important is that you recognise what has happened and take action to prevent any further damage.

Please be aware of and do not fall for these types of messages! The spam filter has been catching a lot of these types of messages lately, but the casual language of this one seems to be defeating our spam filters.

Please ensure that your employees, colleagues and other associates know about these scam messages. You should also remind yourself and your employees, colleagues and associates of the information on our website at the following links:

Thank-you for your time and attention to this vitally important matter. Please contact NinerNet if you have any questions.

Adventures in blocking spam

7 May 2024 06:42:30 +0000

As we’ve said outright and intimated over the years, the battle against spam is never-ending.

One thing we have noticed in the last year or so is that a huge amount of spam comes from certain TLDs (top-level domains), but blocking entire TLDs is a bit radical. We have generally avoided doing so, but the time has come to block the following two alternative TLDs:

  • sa.com, and
  • za.com

These are simply two regular domains, but they are owned by CentralNIC (now “Team Internet” because they can’t make up their minds about how they want to be known) who market them as TLDs — just as NinerNet markets the zam.co domain as an alternative TLD (actually, SLD, second-level domain) for Zambia. Therefore, you can buy the sub-domain your-name.sa.com and your-name.za.com. CentralNIC doesn’t seem to make even a cursory attempt to stop spammers from using their domains to spam, so we now block all messages sent from all addresses on those two “pseudo” TLDs — e.g., spammer1@spammer1.sa.com and spammer2@spammer2.za.com. We’re considering blocking the .top TLD as well, for the same reason, but we haven’t yet. You can certainly block entire TLDs from reaching your email addresses as well, if you feel this rather extreme move will benefit your domain.

If you happen to correspond with a legitimate correspondent on one of those alternative TLDs, please contact NinerNet support and we will work with you to address the problem you will now have communicating with them.

Thanks for your attention to this matter.
