🧵 This CIS Benchmark should be a Level 1 and here is why: it is a COMMODITY ATTACK and allows long term persistent access to tenants that bypasses MFA requirements for users. This attack has been being taught on publicly in offsec classes for years.

I remember learning about the razing of Carthage as a kid and being horrified, yet grateful we lived in a world where something that evil was unimaginable. But that's what's been done to Gaza: not just mass murder, but the wiping out of an entire society. And we all watched it.
Few buildings are standing in northern Gaza in the midst of rubble, and they’re systematically being detonated by the Israeli military with the aim of not leaving intact anything the hundreds of thousands of Palestinians it has been expelling can return to

Gaza is a death camp where Israel is carrying out a holocaust.
Widespread abuse is being carried out by Israeli army of genocide against civilians in northern Gaza after forcing them out of shelters. The world watches in silence. The day will come when these criminals pay the price for their crimes.

Same lesson as every year: I hate spatial puzzles
We're seven days into #AdventOfCode 2024! Have you learned anything new about your programming language / tool / editor of choice?

It's trivial to determine if Okta is being used. Also, IdP's cannot prevent user enumeration, even if their settings in the admin portals suggest they can.
Not sure how easy it is to look up the Okta domain by company FQDN, but @DrAzureAD makes this enumeration very easy for us for Microsoft tenants😈 aadinternals.com/osint/

Jeg er ikke et øjeblik i tvivl om at Mikkel ville stikke en kniv i maven på os alle sammen hvis ikke han fik lov til at lege Herremand
Replying to @tv2politik
Lad bare de venstreorienterede partier få “en knude” i maven, DF og @Mikkel_Bjorn sørger for, at danskerne ikke får en kniv i maven.

Technically a JPEG parser vulnerability can result in you being shown an image that spawns a reverse shell granting remote control, yes. This is a major vulnerability however largely to servers tasked to interpret obscure arbitrary uploaded files. imagetragick.com/

Nothing has made me change my principal stance ("my life is mine, and mine to end") faster than seeing the glee with which British MPs rushed their culling bill through
“people who are terminally ill shouldn’t have to suffer” and “under capitalism and austerity with next to no social supports, crumbling healthcare and constant vitriol about “people who don’t contribute” euthanasia can/will be used as a culling tool” are both true at once

Never lose sight of the fact that network defense is an economic game. Insulating yourself from the costs of predictable noise is leverage.
only morons say that geo blocking is only used by morons. ... I can say this 100% I have worked on [redcated] projects where we had a requirement to use geo blocking. I can say this, if you don't want to spend CPU, LOGS and create noise, geo blocking can be a good tool. It is not a control, it is a tool as part of a defence in depth approach. if you don't understand this then that's a major red flag. only the Sith deal in absolutes!

The US went from “Israel is committed to international law” to “international law does not apply to Israel or any of us for that matter” in less than a year. This is how hyper-normalisation works.
