A Mirai-based distributed denial-of-service botnet tracked as Beastmode has updated its list of exploits to include several new ones, three of them targeting various models of Totolink routers. The authors of DDoS botnets did not waste any time and added these flaws to their arsenal to take advantage of the opportunity window before Totolink router owners applied the security updates.

Distributed Denial-of-service attacks decreased slightly in 2021 but are becoming larger and more complex in nature, an analysis from F5 has found. "The volume of DDoS attacks has fluctuated by quarter, but the unmistakable trend is that these attacks are getting larger," said David Warburton, Director of F5 Labs.

Hackers are compromising WordPress sites to insert a malicious script that uses visitors' browsers to perform distributed denial-of-service attacks on Ukrainian websites. Today, MalwareHunterTeam discovered a WordPress site compromised to use this script, targeting ten websites with Distributed Denial of Service attacks.

During the second half of 2021, cybercriminals launched 9.75 million DDoS attacks, a NETSCOUT report has revealed. These attacks show a 3% decrease from the record number set during the height of the pandemic, yet continuing at a pace that's 14% above pre-pandemic levels.

During the second half of 2021, cybercriminals launched approximately 4.4 million Distributed Denial of Service attacks, bringing the total number of DDoS attacks in 2021 to 9.75 million, a NETSCOUT report reveals. The report details how the second half of 2021 established high-powered botnet armies and rebalanced the scales between volumetric and direct-path attacks, creating more sophisticated operating procedures for attackers and adding new tactics, techniques, and methods to their arsenals.

The attacks are not just growing in number, but also in scale, as the telecommunications company says IoT botnet and amplifier attack capacity exceeds 10Tbps, a significant increase of three-to-four times the size of attacks previously reported. Last year, Nokia shared its findings as part of its DDoS 2021 report, showing that by mid-year the most impactful DDoS were originating from high-bandwidth, high packet-rate, volumetric DDoS attacks.

A massive distributed denial-of-service attack forced Israeli officials Monday to temporarily take down several government websites and to declare a state of online emergency to assess the damage and begin investigating who was behind the incident. In a tweet, the Israel National Cyber Directorate said it had detected the DDoS attack against a communications provider and that several websites had been taken down, though all have since resumed normal activity.

A number of websites belonging to the Israeli government were felled in a distributed denial-of-service attack on Monday, rendering the portals inaccessible for a short period of time. "In the past few hours, a DDoS attack against a communications provider was identified," the Israel National Cyber Directorate said in a tweet.

Rostec, a Russian state-owned aerospace and defense conglomerate, said its website was taken down today following what it described as a "Cyberattack." Rostec claims the website was brought back online quickly and attributed the attack to Ukrainian "Radicals."

DDoS attacks expand as cybercriminals target cloud providers and ransomware victims. Cybercriminals expanded the types of organizations at the receiving end of DDoS attacks.
