The record for the largest recorded denial of service attack appears to have been broken less than a week after it was set. Arbor Networks reported on Monday in a blog post that a 1.7 -terabit-per-second attack took place targeting the customer of a U.S. based internet service provider. Arbor Networks did not specify the victim beyond that description, but said that the ISP had proper defenses in place and that no outages were reported. “It’s a testament to the defense capabilities that this Service Provider had in place to defend against an attack of this nature that no outages were reported because of this,” the company wrote. The attack used the same technique that was used in the 1.35Tbps attack on GitHub on Feb. 28, Arbor Networks said. In both cases, attackers used memcached servers to amplify the requests they were sending to their targets. Arbor Networks says more large attacks using the memcached tactic […]

Do you remember the simpler times when you had a DOS command line, a handful of commands, and you talked to the hardware through a few BIOS and DOS interrupts? Okay, maybe it was a little limited, but nostalgia doesn’t care. Now [mcuhacker] is working on bringing some of those memories back by getting a PC-XT emulator running on an ESP8266.
For the x86 CPU emulator, he ported Fake86 which is written in C, and created an Arduino IDE environment for it. The MS-DOS 3.3 bootdisk image is stored in flash and is accessed as the A: drive. There’s no …read more

Denial of Service attacks that bring down popular websites often involve thousands of hacked consumer devices and servers. While these attacks mainly aim to overwhelm the target system with traffic, in order to deny service to legitimate users, bugs at… Continue reading Application Level Denial of Service – An In-Depth Guide
A group of Princeton and Purdue researchers has shown that it’s possible to mount a denial-of-service (DoS) attack against hard disk drives via acoustic signals. Threat severity Hard disk drives (HDDs) have become the most commonly-used type of n… Continue reading DoS attacks against hard disk drives using acoustic signals
In an entirely new twist on the security of hard disk drives (HDDs), a team of researchers from Princeton and Purdue University have released a paper demonstrating how acoustic signals at specific frequencies can compromise devices that rely on HDD tec… Continue reading Researchers use sound to compromise hard drives in new DOS proof-of-concept
