  like for example: if you defend an org you will likely have: A firewall/VPN server A router/switch A cloud hosted web server Microsoft office 365 Maybe an Remote Desktop Services (or VDI) Service Your daily world will not be full of zero days exploding inside ur VPN server (unless you have a fortinet :P /s) these are rare events. You will have: Phishing/AITM attacks Scams/BEC Identity Dictionary/Brute Force you will also have malware etc. on box IPS/IDS/EDR alerts for behavioural type stuff (most of these are false positives) so software vulnerabilities on the edge in terms of volume will likely not be ur daily grind! identity will.

  @esrtweet I think Excel is the grand bottleneck, or was last I checked. Imagine trying to switch a bank, say your local credit union, over to LibreOffice or any of the StarOffice lineage. Doable in principle, but realistically all the macros are broken (the version of BASIC differs from Excel) and the median banker doesn't have muscle memory for the new keyboard shortcuts anyway. You can obviously use Office 365 from a browser, but you lose access to some features (again, last I checked) and it's still Microsoft. Linux is absolutely fine for everything I use it for. The problem is mostly just lack of attention on things that people who have already adopted it don't themselves need. Window Manager wise, there are several where it's hard to tell the difference between that and Windows or MacOS (or the difference is ~entirely good things).

  @Smileyyeg Works for me. But it was better before the office365 crap was shoved down your throat at every turn.

  Did you know that personal devices can become gateways for corporate data breaches? A recent case revealed a malware attack that accessed Office 365 through a compromised BYOD. The fix? Continuous monitoring and behavior analysis! How secure is your work device? #CyberSecurity

  @authorjoyshaw I use Microsoft's VibeVoice to read it back to me. It's probably the same thing offered by Office365, just on their server and not my local machine.

  I pay for Office365 so the @onedrive experience (esp uploading from mobile) shouldn't be this terrible In contrast, @googledrive is flawless. #Microsoft #onedrive #googledrive

  @Trace_Cohen The long tail uses of AI are enormous. There are so many things that open self-hosted models enable that are off the table with centralized controlled models. Think of *nix on satellites, rather than them phoning Redmond for a license renewal, as an illustrative example. I already see a higher exponential growth in brains investing in open models than frontier models. Similar to how when I worked at Microsoft, the best were all using *nix and *** at home. It will only hang on to the frontier if it can government capture. Now that's a huge possibility, perhaps even greater than 50%. I mean Microsoft's software is terrible, (Windows, Azure, Office 365), and yet crushes it because of gov capture. It would be financially reckless to short without accurately modeling that risk. But in a free market, open >> closed.

  Noticed Microsoft is still shoving stuff down our throats. I have Office 365 without the AI stuff, and noticed the app now has a diamond in the top right corner on apps which is where they push to you AI upgrades.. Just give me the app without all the extra pushed crap.

  Silk Typhoon (HAFNIUM), a Chinese 🇨🇳 state APT, has evolved from on-prem Exchange exploitation to cloud-native supply chain attacks, most recently abusing CVE-2025-3928 in Commvault's Azure-hosted M365 backup SaaS to pivot into downstream customer tenants. - Initial access spans three vectors: CVE-2025-3928 (zero-day in Commvault Web Server, T1190), stolen API keys from privileged cloud vendors (T1195), and leaked corporate credentials found on public repos like GitHub (T1078.004). The Commvault campaign gave them client secrets for Metallic M365 backups, opening direct paths into customer M365 environments via hijacked service principals. - Lateral movement pivots from on-prem to cloud by targeting Entra Connect servers (T1210, T1078.002), enabling privilege sync between Active Directory and Entra ID. Credential dumping and key vault theft support pass-the-hash moves (T1550.002) into Azure. - Persistence relies on adding passwords to existing consented service principals or creating new Entra ID applications named to mimic legitimate Office 365 services (T1098.001, T1036). Web shells handle C2 on compromised Azure VMs (T1505.003). - Collection targets email via EWS and MSGraph APIs, plus SharePoint (T1213.002) and OneDrive (T1213.003), all through OAuth apps with admin consent, a low-noise, API-native exfiltration path that bypasses many endpoint controls. #DFIR_Radar

  I hate the fact that the "Microsoft Office" suite of apps is now the "Microsoft Copilot App" with the fire of 1000 suns. Even trying to work out how to download it when I login to Office365 is a complete nightmare!
