New, by me: Anti-DDoS Firm Heaped Attacks on Brazilian ISPs
A Brazilian tech firm that specializes in protecting networks from distributed denial-of-service (DDoS) attacks has been enabling a botnet responsible for an extended campaign of massive DDoS attacks against other network operators in Brazil, KrebsOnSecurity has learned. The firm’s chief executive says the malicious activity resulted from a security breach and was likely the work of a competitor trying to tarnish his company’s public image.

Analysis Summary
A Brazilian anti-DDoS firm was discovered operating a botnet attacking other Brazilian ISPs — the same type of protection it sells to customers. KrebsOnSecurity, a T1 cybersecurity news source, broke the story with on-record reporting; the firm's CEO attributes the attacks to a security breach and possible competitor sabotage. Independent sources confirm the botnet uses Mirai malware (a known strain from 2016) deployed via compromised TP-Link devices, though the question of whether this was truly an external breach or internal negligence remains contested.
