Takeaway

The Kimwolf botnet, which infects internet-connected devices, recently overwhelmed the I2P anonymity network. This disruption occurred because the botnet operators tried to join hundreds of thousands of infected devices to I2P as a backup communication method, causing widespread outages for legitimate users.
