seeing a lot of F-tier crypto security advice on this app. here’s the best advice you’ll ever find. for “web3” apps, buy a chromebook. they’re very cheap and very secure. you’re not important enough to be targeted on one of these. the end.

@PimEyesOfficial I have the pdf! Will do some analysis on it to see if it is malware (it likely isn’t, this early on in the scam) later tonight. Sadly the scammer is doing a pretty good job sticking to the script. They want me to download trust wallet and then will guide me through it.

Runtime invariant checking is “the way” to best mitigate much of this. This blog post feom @plotchy and crew hits as hard today as it did two years ago when it was written:.

@danielvf With @phylaxsystems assertions, you can define rules that are always checked before a transaction is included on the chain. For example, you can check if the implementation address of a Safe changes as a result of a tx, and if it does, the tx won't be included.

@PimEyesOfficial Apparently they mind the stock market along with extracting mineral resources, crude oil, and they sells agricultural products for factory use. Very interesting

@PimEyesOfficial The address appears to be a commercial office building. It has a car dealership, a wine and spice store, a fullstack software development firm, a cigar bar, etc.

@PimEyesOfficial The website is pretty funny and likely AI generated slop. The only clear reference to Switzerland I found was an address. Zollstrasse 61, 8005 Zürich, Switzerland

@PimEyesOfficial Their website is hosted in the US with Ultahost, a cheap shared VPS provider. Wouldn’t a Swiss investment company host in Switzerland due to their strong privacy protections and legal frameworks? 🤔

@PimEyesOfficial Helpfully, she’s introducing me to a Swiss registered investment company that allows me to make 10% return on my crypto! Wow, sounds great

First things first, I ran the photo through @PimEyesOfficial the fabulous OSINT image search. The photo of “Alice” seems to be camgirl / adult entertainer, unsurprising.
