BitTorrent Fixes Reflective DDoS Attack Security Flaw

BitTorrent Fixes Reflective DDoS Attack Security Flaw

Aug 28, 2015
Two weeks ago, we reported how a serious flaw in the popular peer-to-peer BitTorrent file sharing protocols could be exploited to carry out a devastating distributed denial of service (DDoS) attack, allowing lone hackers with limited resources to take down large websites. Good news is that the developers of BitTorrent have fixed the security issue in its service that is being used by hundreds of Millions of users worldwide. In a blog post published Thursday, BitTorrent announced that the flaw was resided in a reference implementation of the Micro Transport Protocol (uTP) called libuTP , which is used by many widely used BitTorrent clients such as ╬╝Torrent , Vuze and Mainline . The San Francisco company also announced that it has rolled out a patch for its libuTP software that will stop miscreants from abusing the p2p protocol to conduct Distributed Reflective Denial-of-Service (DRDoS) attacks. DRDoS attack is a more sophisticated form of conventional DDoS att

How to Exploit BitTorrent for Large-Scale DoS Attacks

Aug 17, 2015
A flaw discovered in several widely used BitTorrent applications, including uTorrent, Vuze and Mainline , could be used to carry out a devastating distributed denial of service (DDoS) attack that makes it very easy for a single undetectable hacker to bring down large sites. A new research by Florian Adamsky of the City University London shows that open BitTorrent protocol can be exploited to carry out Distributed Reflective Denial of Service (DRDoS) attacks . The bitTorrent protocol is a file-sharing protocol used by Millions of active online users at any given point in the day to exchange files over the Internet. DRDoS attack is a more sophisticated form of conventional DDoS attack where open and misconfigured DNS (Domain Name System) can be used by anyone to launch high-bandwidth DDoS attacks on target websites. In a paper , titled " P2P File-Sharing in Hell: Exploiting BitTorrent Vulnerabilities to Launch Distributed Reflective DoS Attacks ," the resea

Timing is Everything: The Role of Just-in-Time Privileged Access in Security Evolution

Apr 15, 2024Active Directory / Attack Surface
To minimize the risk of privilege misuse, a trend in the privileged access management (PAM) solution market involves implementing just-in-time (JIT) privileged access. This approach to  privileged identity management  aims to mitigate the risks associated with prolonged high-level access by granting privileges temporarily and only when necessary, rather than providing users with continuous high-level privileges. By adopting this strategy, organizations can enhance security, minimize the window of opportunity for potential attackers and ensure that users access privileged resources only when necessary.  What is JIT and why is it important?   JIT privileged access provisioning  involves granting privileged access to users on a temporary basis, aligning with the concept of least privilege. This principle provides users with only the minimum level of access required to perform their tasks, and only for the amount of time required to do so. One of the key advantages of JIT provisioning
