Illegal Content and the Blockchain
15 mar. 2021 - Security researchers have recently discovered a botnet with a novel defense against takedowns. Normally, authorities can disable a botnet by taking over its command-and-control server. With nowhere to go for instructions, the botnet is rendered useless. But over the years, botnet designers have come up with ways to make this counterattack harder. Now the content-delivery network Akamai has reported on a new method: a botnet that uses the Bitcoin blockchain ledger. Since the blockchain is globally accessible and hard to take down, the botnet’s operators appear to be safe.

Someone compromised the entire Twitter network, probably by stealing the log-in credentials of one of Twitter's system administrators. Those are the people trusted to ensure that Twitter functions smoothly.
