Attackers Can Use Sonic and Ultrasonic Signals to Crash Hard Drives

Attackers Can Use Sonic and Ultrasonic Signals to Crash Hard Drives

May 31, 2018
Researchers have demonstrated how sonic and ultrasonic signals (inaudible to human) can be used to cause physical damage to hard drives just by playing ultrasonic sounds through a target computer's own built-in speaker or by exploiting a speaker near the targeted device. Similar research was conducted last year by a group of researchers from Princeton and Purdue University, who demonstrated a denial-of-service (DoS) attack against HDDs by exploiting a physical phenomenon called acoustic resonance. Since HDDs are exposed to external vibrations, researchers showed how specially crafted acoustic signals could cause significant vibrations in HDDs internal components, which eventually leads to the failure in systems that relies on the HDD. To prevent a head crash from acoustic resonance, modern HDDs use shock sensor-driven feedforward controllers that detect such movement and improve the head positioning accuracy while reading and writing the data. However, according to a ne

Scientists Store One Bit of Data on a Single Atom — Future of Data Storage

Mar 13, 2017
Imagine a pocket-sized hard drive capable of storing the entire list of 35 Million Songs? This isn't yet practical, but IBM has just taken a big step towards improving computing technology: IBM researchers just discovered a way to store data on a single atom. Data storage is undergoing dramatic evolution, recently researchers successfully stored digital data — an entire operating system, a movie, an Amazon gift card, a study and a computer virus — in strands of DNA. The IBM Research results announced Wednesday that the researchers have developed the world's smallest magnet using a single atom and they packed it with one bit of digital data. Currently, hard drives use about 100,000 atoms to store a single bit of information — a 1 or 0 — using traditional methods. So, this breakthrough could allow people to store 1,000 times more information in the same amount of space in the future applications. Scientists Store 1 Bit of data on a single Atom, whereas modern hard dri
How to Accelerate Vendor Risk Assessments in the Age of SaaS Sprawl

How to Accelerate Vendor Risk Assessments in the Age of SaaS Sprawl

Mar 21, 2024SaaS Security / Endpoint Security
In today's digital-first business environment dominated by SaaS applications, organizations increasingly depend on third-party vendors for essential cloud services and software solutions. As more vendors and services are added to the mix, the complexity and potential vulnerabilities within the  SaaS supply chain  snowball quickly. That's why effective vendor risk management (VRM) is a critical strategy in identifying, assessing, and mitigating risks to protect organizational assets and data integrity. Meanwhile, common approaches to vendor risk assessments are too slow and static for the modern world of SaaS. Most organizations have simply adapted their legacy evaluation techniques for on-premise software to apply to SaaS providers. This not only creates massive bottlenecks, but also causes organizations to inadvertently accept far too much risk. To effectively adapt to the realities of modern work, two major aspects need to change: the timeline of initial assessment must shorte
