25 Crypto Networks Vulnerable to ‘Fake Stake’ Attack, are Your Funds at Risk?

More than two dozen Proof-of-Stake (PoS) cryptocurrency networks are vulnerable to what has been dubbed a “fake stake” attack. The vulnerability allows a node with a very small stake to overwhelm competing nodes with false data and essentially crash them. Once competing nodes are gone, the attacking node can have a majority of stake on the

roger ver caught doxing and recruiting a brigade to attack a guy who’s suing him

Looks like he is using r/btc to brigade users into attacking some guy who is suing roger.

This is some straight up cowardly bullshit and an abuse of power.

He was called out earlier today and then started trying to cover up his tracks.

If you use Electrum, in case you get a error message that tells you to update please ignore (ongoing phishing attack).

Details here: https://github.com/spesmilo/electrum/issues/4968

copy paste from SomberNight in the github issue:

TL;DR: There is an ongoing attack against users where servers raise exceptions when a client broadcasts a transaction; in this case the error text is displayed as is in the client GUI. The attacker has spawned lots of servers on different /16 IPv4s to increase his chances of being connected to. The error messages are trying to get the user to download and install malware (disguised as updated versions of electrum).` 

apparently previous Electrum versions allow richtext in error messages sent by the server, so the upgrade warning might look legit to people…

Always remember to verify pgp / gpg signatures of bitcoin software you install.
