BlockThreat - Week 46, 2022
GetBlock | DFX | Godwoken | Mina | Oasis
A relatively quiet week after the never ending stream of hacks last month. However, we still witnessed a couple of really rare exploits giving us a taste of what’s to come. A bad actor compromised GetBlock node infrastructure to demand a ransom. Imagine the damage, censorship and arbitrage one could do when taking over a major node provider. Godwoken Chain patched a really rare EVM bug that could have drained the entire chain. It’s been a long time since 51% attacks. The next wave of blockchain level attacks will likely involve EVM or node level exploitation.
I hope you can enjoy this rare week of no major compromises to catch up on the latest in blocksec research and may be even get some rest with your families and friends.
Enjoy the news!
