*** Master Thread on Crypto/Web3 Security ***
After seeing that even seasoned crypto users struggled with crypto/blockchain security aspects, I've decided to create a master thread.
This is my attempt to spread & collect the best Twitter threads on web3 security issues.
After user @Jennifer19375 lost her @BoredApeYC & @doodles NFT in a suspicious @opensea transaction. People wondered what happend.
Original tweet:
Dingalingts explains it in an amazing, in-depth thread:
Just to reiterate. Disconnecting your @MetaMask wallet won't help with this problem. Many people didn't know that (myself included):
Instead, you need to revoke access:
User @osf_nft posted an extensive thread on securing your NFTs and crypto.
[1/2] The $120 million @BadgerDAO hack shows that you need to be careful, even when interacting with an official website.
A good security philosophy is to distrust the infrastructure, never assume that the website you are using has not been compromised.
[2/2] For further information on the attack you can read this thread by security analyst @Mudit__Gupta.
His feed is a great resource if you want to stay up to date on all sorts of web3 security issues.
The following incident is almost exactly one year old, but the learnings are as valuable today as last year.
@HughKarp opened a malicious word file and his @metamask wallet got compromised & he lost 370,000 NXM.
Security company @certikorg recently launched an easy to use tool named #SkyTrace.
It visualizes blockchain transactions in a beautiful drag & drop-enabled graphic interface.
Here's a beginner-friendly guide with great visuals that explains the difference between Hot and Cold wallets:

I also found a great post on @reddit.
The OC covers general security measures:
- Safe eMail provider.
- Password managers
- 2FA.
- VPNs & much more.

$year rug pull.
Free airdrop turned into a honeypot and finally a liquidity pull / rug.
30 #eth were drained.
Amazing and in detail write-up:
There's a new, sophisticated Discord hack/scam making rounds.
Mods get targeted and the attacker is able to even bypass 2FA.
@LittlelemonsNFT fell victim to this attack and they wrote a thread about, so it won't happen to others.
Don't screen share!
1/2
In recent days a few high priced #nfts got sold for a fraction of the current floor.
Short: If you transfer an NFT to a different wallet & you have it listed on @opensea - don't transfer it back to the initial wallet. The listing can still be active.
2/2
@rarible is now aware of the issue and they've created an order management tool that:
"allows you to identify and cancel potential risky sale orders from @opensea"
How do you currently store your seed phrase?
Probably on a piece of paper, right? But what about drying ink, fire and other disasters?
Better go with something more robust.
Like a plate of indestructible Titanium!

Just moments ago another project (@monftersclub) got their @discord hacked.
Details are not 100% clear, but I'm guessing a mod account got compromised and posted a malicious mint page. The attacker got away with Apes & much more.
h/t: @punk9059 🙏
I can only repeat myself:
ALWAYS check the link/URL you're clicking on - no matter who posted/sent it.
Check it - TWICE.
Or you'll lose your precious #NFTs
(Revoke access!!)
Be careful when you click on Google ads.
The top listed sites are often scams, trying to get you to enter your seedphrase.
Here's a brand new example, targeting @LooksRareNFT user:
After another massive scam where a user lost Apes worth over 500 #eth

Crypto OG @richerd put together a masterpiece of a thread on NFT security.
Things to avoid, catching red flags and more!
A must read!
Scammers use "old school" technology to get their hands on your precious "latest technology" assets, aka #nfts. Be careful with email attachments.
The latest scam plays with your fear of losing your most valuable assets.
It revolves around using a fake site named similar to revoke.cash
The Collab Land bot is THE most used Discord bot to verify ownership of NTFs.
In the following thread you'll learn about how to make sure you're interacting with the right bot.
Not even seasoned crypto heads are immune to scams.
Why?
Because the attackers are getting more & more sophisticated.
Here's a valuable collection of sneaky malicious phishing emails and messages to watch out for!
A well-written and easy-to-understand thread about how to spot and avoid (crypto)malware.
Summary:
1. Take your time, read everything a few times. Look for spelling errors.
2. Stay calm.
3. Don't download sketchy files.
4. Don't execute these files.
A simple signature in Metamask can be enough for an attacker to drain your entire wallet.
