Good news! I've uploaded a new post about the most complex and beautiful vulnerability I've ever found, involving patching and uploading deprecated .jar libraries to get RCE on a big target. It's a very technical post, but I hope you like it ! :) hacefresko.com/posts/rce-on-…

The UK ordered Apple to implement back doors. Apple did the right thing and simply removed support for end-to-end encrypted iCloud storage for UK customers, keeping the rest of the world secure. Congratulations, UK! bbc.com/news/articles/cgj54e…

The way to go!
Data breach at The Club Penguin Experience. Let me take a moment to point out what an awesome job these folks have done with their disclosure: 1. They sent this out the same week as the breach occurred 2. They say exactly what happened and what was exposed 3. They say “hash” and name bcrypt as the algo used (I’m giving them a free pass for then saying “encrypted”) 4. They explain how bcrypt can still be cracked and you still need to take precautions 5. They’re force-resetting all passwords 6. They offer to delete the account if this incident concerns any victims 7. Separately, they reached out to me to flag this before I had the opportunity to load it into @haveibeenpwned myself I’m of the firm belief that in the era of ubiquitous data breaches, organisations are judged more by how they handle them than they are for having had one in the first place. Massive kudos to TCPE for such a responsible reaction 👏

I recently "hacked" my smart air purifier 😆 Here's a blog post about it: jmswrnr.com/blog/hacking-a-s… I put a lot of effort into this one; I'm sure any tinkerers out there will find it very interesting! I'd appreciate any feedback or reposts 🙌

I _love_ reading security research, and really appreciate the effort people put into producing it, but please for the love of Dog, add the date it was published! The tweet comes from a wasted morning trying to reproduce research that was obsoleted 4+ years ago 🤦

Om jag vore red teamer så hade jag arrangerat alla mina bakdörrar i bokstavsordning. Shellsortering är viktigt.

Wow, won the @PwnieAwards for most innovative research. Having seen the awards over 10 years ago on my first Black Hat I’m incredibly honoured.

For 25+ yrs police/military/intel agencies/critical infrastructr in 120 nations relied on TETRA radio standard to secure critical comms. But Dutch researchers examined secret algorithms used in TETRA and found something startling - an intentional backdoor wired.com/story/tetra-radio-…

Hjärtstopp hörni. Häromveckan åkte familjen hem från Schiphol. Mannen framför mig i säkerhetskontrollen ramlade raklång i backen. Min fru (som också är läkare) och jag vände honom på rygg - ingen reaktion. Några snarkande andetag och sen slutade han andas.
