Mastodon, a rival to Twitter/X, has been targeted by a spam attack that exploited vulnerabilities in the 'Fediverse', highlighting security concerns. Over several days, attackers focused on smaller Mastodon servers by creating spam accounts, a shift from previous attacks that targeted only large servers. TechCrunch, citing @sarahpereztc, reported that Eugen Rochko, associated with Mastodon, noted this change in attack pattern. Additionally, Discord has been criticized for not taking action against a server that coordinated these spam attacks. The incident raises questions about the security measures in place within the 'Fediverse' and the responsibilities of platforms like Discord in preventing such abuses.
