My day started with welcoming agmKHzyPT1wK_sLBlBs0KzXZt_18274@skapet.bsdly.net to the imaginary friends population at https://nxdomain.no/~peter/traplist.shtml, this one generated by whatever runs the service check@taknc.com, hosted in AS134963 (Alibaba) address space.

How is your day going?

Welcome new imaginary friends glenn.finch@bsdly.net and stewart.ashton@bsdly.net to the cast of millions at https://nxdomain.no/~peter/traplist.shtml (served up to us today by mxtest@serverscannerpro.com and mxtest@emailengineexpert.com, respectively).

My favorite new imaginary friend (aka spamtrap) today was however Noreplyadmin@bsdly.net, a faked sender address.

The other horribly nonsensical thing I saw during the last 24 hours was the error messages GNU Emacs emits when it is faced with a file of a size that exceeds its expected per-buffer memory allocation.

Fortunately a sane solution was found for that particular problem (split that big hand generated log into smaller pieces) - search for "this log directory" in https://nxdomain.no/~peter/traplist.shtml #spamtraps #greyptrapping #spamd #antispam #cybercrime #imaginaryfriends

Anyone know any OK anti spam/phishing/etc addon filter products for O365 email that sucks less than the woeful MS-Defender rubbish?

And that handle relatively small orgs.. just wasted my time "getting a quote" from a vendor to find out they don't handle under 100 seats.

This lame "contact us for a quote" stuff is a big waste of time.

Still teasing and mulling a #greytrapping with #openbsd #spamd retrospective, so perhaps reprising "Maintaining A Publicly Available Blacklist - Mechanisms And Principles" (2013) https://nxdomain.no/~peter/maintaining_a_publicly_available.html might spur some inspiring comments?

I look forward to hearing your thoughts. #spam #email #smtp #antispam #cybercrime

Verbessert AI mit LLM die Erkennnug von Spam oder sind traditionelle Verfahren wie Bayes-Filter oder Fuzzy Hashing zielführender? Ich durfte auf der #FOSDEM 2025 in Brüssel bei einem interessanten Vortag von Vsevolod Stakhov mit anschließender Diskussion live mit dabei sein.

In another thread, @puppygirlhornypost2@transfem.social talks about challenges regarding proliferation of spam (or other unwanted content) on the fediverse:

... I was talking about reddit's "posts require approval" mode. Something that might be of use for new accounts registering on pixelfed instances to prevent things like gorespam from occurring.

NodeBB has the post queue (our name for it), and it works really well to stop drive-by spammers. Most cheap spam is easily identified as such, and it's only a couple clicks to send them to /dev/null.

More recently, and especially since we've been federating posts outward, we've started encountering possibly LLM generated content entering our post queue. It could be that these accounts are legitimate users creating an account to respond to remote content, but it's equally likely that they're attempting to create plausible content in order to pass validation, before proceeding to post spam.

At least here on community.nodebb.org it's trivial to discover, because this forum is for NodeBB support/discussion, and a post out of the blue responding to a post about Trump or Israel/Palestine is very obviously not meant to be on this forum, although it's definitely one of those "hard problems" for more general instances.

Is SPF Simply Too Hard For Application Developers?
The Sender Policy Framework (SPF) is unloved by some, because it conflicts with some long-established SMTP email use cases. But is it also just too hard to understand and to use correctly for application developers? https://nxdomain.no/~peter/is_spf_too_hard_for_appdevs.html

And ref previous toot, the 1006089th imaginary friend to join the collection at https://nxdomain.no/~peter/traplist.shtml is , mail.protection.outlook.com@bsdly.net following this sequence: https://nxdomain.no/~peter/blogpix/2025-01_18_johnson@vicglobalintelligence.com_to_mail.protection.outlook.com@bsdly.net.txt

The bots never cease to amaze #openbsd #spamd #greytrapping #antispam #cybercrime

And the two episodes combined proved addendum-worty, at least, see https://nxdomain.no/~peter/harvesting_the_noise_revisited.html

Likely not blogworthy in itself, but #openbsd #spamd aficionados will get a light chuckle from hearing that some scraping and massaging relevant logs had the number of imaginary friends at https://nxdomain.no/~peter/traplist.shtml for our not-friends to play with roll past the one million mark in the early hours of today CET.

The recent update of https://nxdomain.no/~peter/harvesting_the_noise_revisited.html has links to more info. #spam #antispam #greytrapping #blocklists #cybercrime

Why can't we agree on a #FirstContactProtocol for #Email?

That the first time someone sends you an email, your email app checks if this address is in the allow-list. If it's not your client will ask you to add this person to the allow- or block-list

If the email is signed with OpenPGP your email app checks if the key is in the allowed-keys list and if not ask to add it to this list or to the blocked-keys list. This way people can change email address w/o re-applying

I was reminded that the old "Effective Spam and Malware Countermeasures - Network Noise Reduction Using Free Tools" https://nxdomain.no/~peter/effective_spam_and_malware_countermeasures.html (a somewhat overweight article/blogpost) might still be worth your time if you are that kind of person #openbsd #spamd #antispam #greylisting #greytrapping #cybercrime #freebsd #freesoftware #libresoftware (if nothing else for the references to other items of interest)

Already somewhat blasé from life in the honeypots, yours truly registers an even more bizarre level of events after a some routine logs spelunking
