New Mirai botnet targets industrial routers with zero-day exploits
A relatively new Mirai-based botnet has been growing in sophistication and is now leveraging zero-day exploits for security flaws in industrial routers and smart home devices. Exploitation of previously unknown vulnerabilities started in November 2024, according to Chainxin X Lab researchers who monitored the botnet’s development and attacks. One of the security issues is CVE-2024-12856, a […]
Malware botnets exploit outdated D-Link routers in recent attacks
Two botnets tracked as ‘Ficora’ and ‘Capsaicin’ have recorded increased activity in targeting D-Link routers that have reached end of life or are running outdated firmware versions. The list of targets includes popular D-Link devices used by individuals and organizations such as DIR-645, DIR-806, GO-RT-AC750, and DIR-845L. For initial access, the two pieces of malware […]
Operation PowerOFF shuts down 27 DDoS-for-hire platforms
Law enforcement agencies from 15 countries have taken 27 DDoS-for-hire services offline, also known as “booters” or “stressers,” arrested three administrators, and identified 300 customers of the platforms. The action is part of ‘Operation PowerOFF,’ an international initiative to combat cybercrime, specifically distributed denial-of-service (DDoS) attacks. DDoS-for-hire services are platforms that utilize botnets on compromised […]
Recently patched CUPS flaw can be used to amplify DDoS attacks
A recently disclosed vulnerability in the Common Unix Printing System (CUPS) open-source printing system can be exploited by threat actors to launch distributed denial-of-service (DDoS) attacks with a 600x amplification factor. As Akamai security researchers found, a CVE-2024-47176 security flaw in the cups-browsed daemon that can be chained with three other bugs to gain remote code execution […]
Cloudflare blocks largest recorded DDoS attack peaking at 3.8Tbps
During a distributed denial-of-service campaign targeting organizations in the financial services, internet, and telecommunications sectors, volumetric attacks peaked at 3.8 terabits per second, the largest publicly recorded to date. The assault consisted of a “month-long” barrage of more than 100 hyper-volumetric DDoS attacks flooding the network infrastructure with garbage data. In a volumetric DDoS attack, […]
