Biggest-Ever DDoS Attack (1.35 Tbs) Hits Github Website

Biggest-Ever DDoS Attack (1.35 Tbs) Hits Github Website

Mar 02, 2018
On Wednesday, February 28, 2018, GitHub's code hosting website hit with the largest-ever distributed denial of service (DDoS) attack that peaked at record 1.35 Tbps. Interestingly, attackers did not use any botnet network, instead weaponized misconfigured Memcached servers to amplify the DDoS attack. Earlier this week we published a report detailing how attackers could abuse Memcached, popular open-source and easily deployable distributed caching system, to launch over 51,000 times powerful DDoS attack than its original strength. Dubbed Memcrashed , the amplification DDoS attack works by sending a forged request to the targeted Memcrashed server on port 11211 using a spoofed IP address that matches the victim's IP. A few bytes of the request sent to the vulnerable server trigger tens of thousands of times bigger response against the targeted IP address. "This attack was the largest attack seen to date by Akamai, more than twice the size of the September 2016
602 Gbps! This May Have Been the Largest DDoS Attack in History

602 Gbps! This May Have Been the Largest DDoS Attack in History

Jan 09, 2016
Cyber attacks are getting evil and worst nightmare for companies day-by-day, and the Distributed Denial of Service (DDoS) attack is one of the favorite weapon for hackers to temporarily suspend services of a host connected to the Internet. Until now, nearly every big website had been a victim of this attack, and the most recent one was conducted against the BBC 's websites and Republican presidential candidate Donald Trump 's main campaign website over this past holiday weekend. Out of two, the largest DDoS attack in the history was carried out against the BBC website: Over 600 Gbps . Largest DDoS Attack in the History The group calling itself New World Hacking claimed responsibility for taking down both the BBC's global website and Donald Trump's website last week. The group targeted all BBC sites, including its iPlayer on-demand service, and took them down for at least three hours on New Year's Eve. At the moment, the BBC news organiz

Making Sense of Operational Technology Attacks: The Past, Present, and Future

Mar 21, 2024Operational Technology / SCADA Security
When you read reports about cyber-attacks affecting operational technology (OT), it's easy to get caught up in the hype and assume every single one is sophisticated. But are OT environments all over the world really besieged by a constant barrage of complex cyber-attacks? Answering that would require breaking down the different types of OT cyber-attacks and then looking back on all the historical attacks to see how those types compare.  The Types of OT Cyber-Attacks Over the past few decades, there has been a growing awareness of the need for improved cybersecurity practices in IT's lesser-known counterpart, OT. In fact, the lines of what constitutes a cyber-attack on OT have never been well defined, and if anything, they have further blurred over time. Therefore, we'd like to begin this post with a discussion around the ways in which cyber-attacks can either target or just simply impact OT, and why it might be important for us to make the distinction going forward.
