Once it became evident that IoT devices can be relatively easily enslaved in botnets and that even their limited power can be used for a variety of nefarious purposes, it was open season for malicious actors. First, they targeted IoT devices with default or weak passwords, and manufacturers and users began changing them. Then they used known vulnerabilities, and IoT vendor increased their efforts to push out patches. Now, some of the botmasters are making … More ?
DDoS attacks continue to be an effective means to distract and confuse security teams while inflicting serious damage on brands. Neustar discovered that brands experienced a 27 percent increase in the number of breaches per DDoS attack, despite suffering similar attack levels in the same time period last year. Attackers are getting higher yields from determined attacks Data from the report shows attackers are achieving higher levels of success against brands they only hit once: … More ?

DDoS attacks: Brands have plenty to lose, even if attacked only once
Three out of every four DDoS attacks employed blended, multi-vector approaches in the second quarter of 2017, according to Nexusguard. Distribution of DDoS attack vectors The quarterly report, which measured more than 8,300 attacks, demonstrated that hackers continued to rely on volumetric attacks to overwhelm system resources. For example, UDP-based attacks increased by 15 percent this quarter, targeting hijacked devices connected to the IoT, and overtaking SYN, HTTP Flood and other popular volumetric attacks in … More ?
The risks insecure medical devices pose to patient safety are no longer just theoretical, and compromised electronic health records may haunt patients forever. A surgical robot, pacemaker, or other life critical device being rendered non-functional would give a whole new, and wholly undesirable, meaning to denial of service. Malware like MEDJACK has been used to infect medical devices and use them as staging grounds to attack medical records systems. IoT ransomware is on the rise … More ?

Mirai is the name of the worm that has taken control of many IoT devices around the world and used them to mount DDoS attacks, the most high-profile of which was directed against US-based DNS provider Dyn and resulted in many websites and online services being inaccessible for hours on end. Its source code was leaked by the author, which lead to the creation of more botnets, and an increased fear that we’ll soon witness … More ?

Every hour of every day, computer systems and IoT devices are under attack by bots trying to recruit them into growing botnets. Security researchers have recently highlighted two of these threats coming after Linux- and BusyBox-based systems and devices. Amnesia A year after security researcher Rotem Kerner discovered a remote code execution vulnerability that affected digital video recorders (DVRs) manufactured by Chinese company TVT Digital and sold by more than 70 different vendors around the … More ?
IoT devices are ideal targets for attackers looking to build DDoS botnets because they have limited or non-existent security features. Some IoT devices utilize hard-coded default passwords. Many devices have unnecessary services running that can be exploited, and others have unprotected management interfaces. Most important for DDoS attackers, IoT devices offer high-speed connections that are always on, which allows for a large, predictable amount of attack traffic volume per compromised device.

Arbor Networks released its 12th Annual Worldwide Infrastructure Security Report offering direct insights from network and security professionals at global service providers, cloud/hosting and enterprise organizations. The stakes have changed for network and security teams. The threat landscape has been transformed by the emergence of IoT botnets. As IoT devices proliferate across networks, bringing tremendous benefits to businesses and consumers, attackers are able to weaponize them due to inherent security vulnerabilities. The largest DDoS attack … More ?
The European Union Agency for Network and Information Security (ENISA) has released a new report to help IT and security officers of healthcare organizations implement IoT devices securely and protect smart hospitals from a variety of threats. We all know that attacks against hospitals are increasing, but according to security experts, ransomware and DDoS attacks are just the start. The report, compiled with the help of infosec officers from several European hospitals and consultants and … More ?

The Internet of Things (IoT) is now a major force in the weaponization of DDoS. In 2016, IoT botnets have fueled a number of attacks, including the largest-ever DDoS attack, and that role will only grow in the coming years. The tools to carry out these attacks are freely available to the public, and the IoT is expected to be 20 billion devices strong by 2020, so expect more frequent and disruptive attacks from a … More ?
