Happy to announce that I have been selected as hackerone co-ambassador for England alongside @njcve_ Looking forward to building the community here in London. Sign up at h1.community/england-hacker… #hackerone #BugBounty

@njcve_ @Random_Robbie That's a really clever tip!

@Random_Robbie first thing I do with any unknown numbers is add them as a contact, and refresh signal/tele/whatsapp. You'd be surprised how much info you can get from that alone.

Do I have any #OSINT people following me I could do with some assistance tracking a phone number sending inappropriate messages to my 10 year old

@H4cktus @Hacker0x01 Congratulations mate! Knew it was just a matter of time :)

Top 100 on @Hacker0x01 ! 🌵

@rez0__ That is super useful!

@BuildHackSecure @NahamSec Actual lol!

@NahamSec Debugging a VW golf.

I need to record a video tonight before I leave in the morning. Open to suggestions 🤔

@monkehack Haha love that!

I was getting annoyed at LinkedIn bots, so I wrote my name backwards and reversed the whole thing with RTLO characters to look normal. If anyone was using sales bots, it would message me with "Hi Rettoc!". It also reversed ALL Linkedin notifications with my name. #hacktheplanet

We have released another 10 tickets for the H1 event in Manchester. If you missed the first ticket drop, now is your chance! h1.community/events/details… #hackerone

@monkehack Very jealous! One of my favourite places. Enjoy!

I’ll be at H1-6102 in Sydney, Australia in June! I’ll also be visiting New Zealand and Taiwan after that - if you’re based in any of those countries, let me know! #BugBounty
