CyberSec for everyone

@UK_Daniel_Card @brysonbort @ZackKorman Heh don’t get me started…

@UK_Daniel_Card All good in the hood dude

[David Guest @devslashdg]

Wow. Managing to push two massive falsehoods in a single article. https://t.co/Bv5IlDINb2 None of this is true! (One for you to destroy again @UK_Daniel_Card 😀)

[David Guest @devslashdg]

No. It sends the message that nobody should do digital business in the UK and that its citizens should use a VPN. You’ve protected literally nobody. You’ve reduced security. Further details can be provided upon request.

[David Guest @devslashdg]

@UK_Daniel_Card Can confirm. Spent more than a decade doing MNO security and SIM farms are hardly a rare find! Claims of “must be nation state” are ridiculous. If I had money to burn I could knock one up in no time. Looks pretty unremarkable to me.

[Robert Graham @robertgraham]

I wrote up a quick blogpost why this SIM farm story is bogus and why you journalists should feel embarrassed for not questioning such obvious propaganda.

RFKjr's claim is that 40% to 70% of mothers believe their child's autism is due to vaccines, and we should believe mothers.

This sort of argument is such pure dumbfuckery that it cannot be refuted.

[David Guest @devslashdg]

@HackingDave Sorry to hear that dude 😢

[David Guest @devslashdg]

@UK_Daniel_Card Had this the other day. Sitting in a cafe on a call. A Teams call no less with my phone out as I’m watching the screen. And someone decided it’d be a great time to approach me for a chat. Not even someone I’d ever seen before! 🤣

@notsky Excellent engineering decision, assuming the circular feature was non-existent.
- The UX team required circular
- Management didn't want to spend time on it
- A clever mind offered this workaround that took years for someone to discover
And the internet thinks they are smarter.

The IT admin turned security admin is a really great career trajectory.

It sets you up nice well to expand into just about any other security role, from pentesting to DFIR.

1 experienced, thoughtful, resourceful IT admin is worth their weight in gold

@UK_Daniel_Card Maybe her husband said “I tripped, fell over and my trousers came down, my head hit the keyboard and porn came on. I was checking to make sure I had no injuries by stroking myself” and wants to believe it…

[David Guest @devslashdg]

There is no reason to disable this feature on your primary device generally and I would recommend against doing so unless you have a special use case.

🚨 Important Safety Warning 🚨
If you or someone you know keeps a second/hidden phone for safety reasons, please be aware:
The emergency alert will be tested 7 September at 1500. This could reveal hidden devices. Turn off alerts in advance.
#EmergencyAlert #DomesticAbuseSafety

[David Guest @devslashdg]

On iPhone under Notifications, scroll to the bottom and switch alerts off. Even if the phone is turned off at 1500, the alarm will sound when it’s turned back on and it gets the notification from the network.

[David Guest @devslashdg]

The irony is that the combination of the Investigatory Powers Act and Online Safety Act have probably done more to harm cyber investigations and online safety than any other statute in British history. The number of people now “going dark” will be astronomical.

@UK_Daniel_Card Reminds me I also need to risk model members of my team being whisked away in a van at night and being hit repeatedly with a rubber hose
