Also Ghidra: WHAT IS DS, ES, That's segment zero! Must be!

Seriously though. Does anyone know how to deal with 16-bit code in Ghidra?

The more and more old servers I see close, the more intolerable it is that Mastodon still doesn't offer a way to migrate data like posts to new accounts. A user's post history is valuable, and it's more valuable the older the account is. Users *should* have the option to migrate those to a new server!

@adamshostack where are you seeing reference to symmetric keys?

In the Technical Details section on Actor Tokens, it says “These hybrid setups used to provision a certificate credential on the Exchange Online Service Principal (SP) in the tenant, with which it can perform authentication.” . Adversary would then use the (x509) cert (and private key) to authN to eSTS (the Entra IdP), get one of these wacky “Actor Tokens” that AAD Graph doesn’t validate properly.

eSTS does support both x509 and client secrets for an SP to authN, but client secrets are just CSPRNG-generated passwords. They’re bearer tokens, not symmetric AES or RC4 keys.

I’d argue the causes were the ad-hoc “Actor Tokens” for impersonation (wrapping in an unsigned JWT: what the heck?), and that AAD Graph still hasn’t been shut down. It’s been deprecated since before I joined MS Identity in 2020, and has been a steady source of vulns

On the 26th of September I will also be streaming a birthday demoparty from London, I heavily encourage everyone to send entries!

Holy moly. The DOJ just unveiled their charges against Jubair, alleging he was involved in 120 intrusions and extortion against 47 US entities. The complaint alleges victims paid at least $115 million in ransom payments. At a hearing today in the UK, it emerged that Jubair had access to $200 million in crypto, and Flowers $7M

I'm only now figuring out that today's npm attack is distinct from yesterday's npm attack.

Checking on the website of our local #library and found that there is a dedicated status for orders where "all instances of the document *disappeared* and the librarian sees no good chance that they will be found in the foreseeable future".

I mean, you had one job!

Edit: can't wait for my bank to introduce the "sorry bro, we blew that money on coke" status :D

One Token to rule them all - obtaining Global Admin in every Entra ID tenant via Actor tokens

https://dirkjanm.io/obtaining-global-admin-in-every-entra-id-tenant-with-actor-tokens/

"I found the most impactful Entra ID vulnerability that I will probably ever find. This vulnerability could have allowed me to compromise every Entra ID tenant in the world"

Who could have figured out that automatically downloading half the internet and ten thousand always-changing dependencies every time you build could actually be a weakness?

Took me way too long due to scope creep, but: The Hacker Webring is now up!

Members vote for other users. Given enough users, the whole system should work by itself, without administrative intervention.

It’s still somewhat rough around the edges, but functional!
