JFC, get a newer phone! How do they somehow think the Telcos are replacing the 4G/3G network with something less effective? https://www.abc.net.au/news/2024-03-23/3g-switchoff-telstra-emergency-bushfires-phone-network-gippsland/103604594

@franksting 5G distance is significantly reduced ( at least on the frequencies in use in Canada) compared to 3G/LTE. This is creating an access problem in a country that is 90% low population. Just did a 9400 km road trip and 5G only reliable in short distance from towers.

@franksting I'll defer to you as you know better than me, but I feel skeptical that coverage will match 3G and that can be a concern. Feels like 3G can be turned off in urban/suburban but might be rethought in specific deployments.

Public service ads are hard. Congratulations to the BC Securities Commission on incredibly smart and impactful awareness of crypto scams. HTTPS://cryptoscams.ca

@edwiebe No, I am being genuine. The ads they are running use the real lures and scams people (especially of TV watching age) are susceptible to. Public service ads are usually to appear to be doing something, but I think they hit the nail on the head with this batch.

this character on the 90s television sitcom "family matters" was famous for the tag line "did I do that?"

@rfb this feels deeply out of context.

@rfb OK, back at ya'. This popular character from a 90s sitcom was the last time a popular Nazi was portrayed on TV before Donald Trump.

@rfb Not a literal nazi,

Off on a road trip. Went thru Kamloops BC ("Tournament Capital of Canada"?), Revelstoke, Golden, Banff, Lake Louise, Canmore, Calgary, Medicine Hat, Moose Jaw, Regina, and Winnipeg so far. First long distance trip in our EV. So far, (mostly, f u Moose Jaw charger repair guy) so good. Shocking how windy the prairies can get in winter and how much it affects efficiency.

@franksting climate change... clear and dry when we went through. Exceptionally mild winter.

My "big picture" take on the LockBit disruption this week is now live. We are seeing more frequent law enforcement action against all sorts of cybercrime groups and I think we need to step back and take stock of what is working and what isn't so we put our energies where they are likely to achieve the best outcomes.

Come for my .02 cents and stay for the snark. https://news.sophos.com/en-us/2024/02/21/lockbit-lessons-learned-on-winning-the-war-on-cybercrime/

I was delighted to see my talk "Building defensive playbooks from others misfortune" from RootCon 2022 was just surprise posted to YewTube. Check it out, still relevant after 18 months. https://yewtu.be/watch?v=V_UrmsnOBbg

Death to Lockbit.. Long live Lockbit! When is a ransomware scumbug truly dead? Sanctions? Fancy new name? New handles? Steal bracelets? Maybe this should be a poll.

@chetwisniewski@securitycafe.ca avatar

I know many of you are experts, but I think I have a slightly different take than most on this whole Lockbit affair. Odds are I am wrong, but that hasn't dissuaded me from expressing my thoughts before, so I hope to publish a blog in the next day or so with my thoughts. Things are never quite what they seem, and I wonder if this is a genuine step change for law enforcement's approach to this intractable dilemma.

@jc I think it goes deeper, intentionally or not. Trust is a bizarre asset in the criminal world and compromised assets could be any||every where.

@jc Hopefully not long, I passed it to my colleague for an edit a few minutes ago and we should be able to post it
tomorrow North America time.

Just got back from an amazing dinner with my wife for our 25th anniversary. I forgot to photo the amazing Alberta bison strip loin. Yum.

@chad The only logical way to store carbon in the ground is as oil and coal. Cheap, easy solution. Don't drill it out or mine it and it is 100% efficient.

Through a series of errors of which I would rather not recount I had to revert my Mastodon instance to a backup from 23 Dec 2023. If you followed me or anyone else on securitycafe.ca since then, please refollow. I am a master at destroying valid backups I learned yesterday.
