The growth of DDoS-as-a-Service has resulted in a wide array of powerful and affordable DDoS services available to the public. Since the beginning of 2016, Radware’s ERT Research division has been monitoring a number of services available on both the clear and the darknet. These off-the-shelf attack services have been used to launch attacks on a number of industries including ISPs, media, financial service companies and online gaming. These services are commoditizing the art of hacking by making it possible for novices with no experience to launch large scale attacks.

Darknet markets are nothing new but they have grown considerably in popularity since the highly publicized take down of the Silk Road marketplace in October of 2013. Since then users around the world have flocked to these sites in search of drugs and other illicit services. Due to the high demand and availability for these items many marketplaces began to spring up across the Darknet. Most of these marketplaces feature drugs, but after the Silk Road takedown, marketplaces began offering items Silk Road wouldn’t allow. These items included weapons, credit cards and other malicious services like malware, DDoS-as-a-service and data dumps.

Last month on Friday, May 12th a global incident related to a ransomware variant named WannaCry broke out, targeting computers around the world. Everything from personal computers to corporate and university networks were affected by this campaign. The campaign spread across networks leveraging a recently disclosed vulnerability in Microsoft SMB service. On March 14th 2017, Microsoft released MS17-010, a security update, that addressed and patched six CVEs. Five were remote code executions and the sixth was related to information disclosure.

Over the last few days, Radware’s Security Research Groups have been monitoring a global incident related to a ransomware variant named WannaCrypt, also known as WannaCry, WanaCrypt0r and wcry. On the morning of Friday May 12th, a ransomware campaign began targeting computers around the world. Once a computer was infected, a worm replicated itself across the network, targeting other computers as well. Worms use a computer network to propagate to other machines and infect them with the malicious payload.

The idea of an Internet of Things (IoT) botnet is nothing new in our industry. In fact, the threat has been discussed for many years by security researchers. It has only now gained public attention due to the release and rampage of the Mirai botnet. Since Mirai broke the 1Tbps mark in late 2016 the IoT threat has become a popular topic of conversation for many industries that utilize connected devices. Not only are companies worried about if their devices are vulnerable but they are also worried if those devices can be used to launch a DDoS attack, one possibly aimed at their own network.

“For Educational Purposes Only”

February 15, 2017 — by Daniel Smith2

Education, freedom and knowledge. These are the pillars for higher learning, but have often been used to describe some open source projects and services that have the potential to be abused by those that are not so innocent. Over the last two years, tools like stressers, Remote Administration Tools (RAT) and ransomware have been published under these pretenses, but do they serve a legitimate purpose? These projects have set off an international debate in the information security community and many wonder if they should be available to the public. Often the justification for these projects is that they are intending to show the potential risks so they can be used to prevent infections or reduce potential damage. With stressers, they claim that the services are to be used to improve and test security products and to understand attack behavior targeting their network. But are they?
