Distributed Denial of Service (DDoS) attacks have become a growing threat that, to a large extent, have become commoditized by DDoS-for-hire, or “booter”, services. In this case study, we analyze leaked fine-grain “ground truth” data from a larger booter service, VDoS, which earned over $597,000 over two years and launched 915,000 DDoS attacks and 48 attack years (i.e., the amount of DDoS time faced by victims of VDoS). The time period of the data includes data before and after a payment intervention, providing a rare opportunity to understand how it impacted VDoS’s operation

Individuals and institutions affected by the WannaCry ransomware attack face a Hobson’s choice—the malicious software (malware) encrypts a user’s documents while the decryption keys remain in the hands of the cybercriminals.

… Justin Cappos, an assistant professor of computer systems and security at New York University [Tandon School of Engineering], suggested one quick fix for future security updates. Rather than telling users to update their systems for a “security patch,” Windows could offer a bleak warning: “Hackers can get into your computer right now, so please update so we can fix that.”

President Trump wants to crack down on botnets, the networks of hacked zombie computers that criminals or adversaries can use to carry out large-scale cyberattacks. Achieving this would surely disrupt the cybercriminal infrastructure, but it will also require that the administration overcome monumental technical and political hurdles. Zachary K. Goldman comments in the MIT Technology Review.

The recent ransomware cyberattack has claimed an estimated 300,000 computers in 150 countries. Cyber security expert Justin Cappos is a professor at NYU’s Tandon School of Engineering. He described what the WannaCry malware is doing now and how it invades computers through a loophole in Microsoft Corp’s Windows operating system. He said the malware exploits a weakness in the operating system to spread from computer to computer.
