@npub178r…qekt Following you has a price... In this case about $100 USD.

What if AT&T had MFA enabled on their Snowflake... and were SIM swapped?

@npub1hvd…9sq9 I said the same to a friend and colleague a few hours ago, it's been clear for awhile and it is starting to look shameful.

@npub1hvd…9sq9 Was this just random violence or somehow targeting your group? Not that it matters, people should support the victim either way, but it seems so odd/random?

COVID for the second time. I'm starting to think I can no longer travel to speak at InfoSec events. Masked flying, masked on transit, etc. Only unmasked for a while at the event itself and this is my reward.

@npub17lg…9uux @npub1t04…xj4g I'm surprised this was effective considering many more ransomware crews are doing "remote ransomware", effectively running the encryption on an unprotected device and connecting to the shares over the network. Would work against Netware shares as well as anything else...

Looks like Lush Cosmetics were victims of Akira as they have appeared on their leak site. Akira has exploited unpatched Cisco ASA VPNs in the past, wondering if the same here? They use them according to Shodan data.

Reminder folks, it is not too late for your child to write a letter to Santa and receive a reply. Canada Post will respond to any child's letter through Christmas if it is received from anywhere in the world (with the proper postage to get here if outside Canada, free no postage required in Canada) - https://www.canadapost-postescanada.ca/cpc/en/our-company/giving-back-to-our-communities/write-a-letter-to-santa.page

@npub147m…7rue I've been to the University of Otago a few times on work trips, had no idea it was far enough south for that kind of show. How far North can you see a decent display?

I was going to permanently delete my X account on 31 December, but have been talked out of it due to impersonation issues. I stopped posting over a year ago.
I think I've decided on a new approach. Instead of stopping tweeting entirely, every time I post something meaningful here, I will post a message on X simply saying I have thoughts on #topic and then link to this account.

@npub1dl0…49nf I mean, it does and it doesn't. Therein lies the problem. Happy running my small instance as well, but federations comes at an efficiency penalty. Today my instance is only consistently interacting with 10 primary large-ish instances. This becomes a problem when its thousands for each instance. Scalability is always cheaper centrally and there is an ever increasing penalty for distributed servers.

2,200,000 hectares (~5.5 million acres, slightly bigger than New Jersey slightly less than New Hampshire in land size) burned in British Columbia so far this year (1 month to go in fire season). Old record was 1,300,000. Unbelievable tragedy and I'm afraid we are in for more if we don't take action to halt climate change. #ClimateChange #ClimateCrisis #ClimateEmergency

I guess I shouldn't be surprised, but I am certainly disappointed that the closed captions on the Black Hat videos, which I paid $2500 for are widely inaccurate and have not been proofread. I feel bad for deaf people who rely on these, as the machine generated ones are questionable at best. For free content I understand relying on it, or even for real-time content, but for recorded video that you pay a premium for this is unacceptable. #InfoSec #AI #Accessibility

Sadly the list of what they will do versus what you should do is a bit lopsided.

@npub178r…qekt Seems like this scheduling situation would have been entirely avoidable. Many of these collisions have been occurring more and more often. Do we have too many events or are we just not looking outside of our bubbles enough?
