5d storage technology can fit 500tb on a small disc

While most consumers today are perfectly satisfied with the capacity and reliability of modern solid-state drives (SSDs), various organizations that are required to archive massive quantities of data are deeply aware of the limitations of not just SSDs but other currently available storage technologies as well.

Soon, they might be able to store up to 500TB of data on a CD-sized disc thanks to a new energy-efficient laser-writing method for producing high-density nanostructures in silica glass. Called five-dimensional (5D) optical data storage, this method could theoretically be used to archive data for as long as 13.8 billion years, and the optical discs produced by it can survive temperatures as high as 1,000 degrees Celsius.

“With the current system, we have the ability to preserve terabytes of data, which could be used, for example, to preserve information from a person’s DNA,” said Peter G. Kazansky, leader of the research team behind the new data storage technology.

5D optical data storage isn’t actually an entirely new invention, but its practical applications were greatly limited in the past because of its slow write speed. To improve it, the research team from the University of Southampton in the UK used a femtosecond laser to produce an optical phenomenon known as near-field enhancement, minimizing the thermal damage that prevented earlier researchers from making 5D optical data storage truly usable.

“This new approach improves the data writing speed to a practical level, so we can write tens of gigabytes of data in a reasonable time,” said doctoral researcher Yuhao Lei. By a reasonable time, Lei means about 100 pages of text (roughly 230 kilobytes of data) per second.

When you compare that figure to the writing speeds of modern SSDs (anywhere from 200 megabytes per second to 4,000 megabytes per second), it becomes apparent that regular consumers won’t be replacing their storage drives with it anytime soon.

new variants of android spyware are targeting middle east users

British security software and hardware company Sophos has recently revealed that new variants of Android spyware used by the C-23 group are actively targeting users in the Middle East.

C-23, also known as GnatSpy, FrozenCell, or VAMP, is what cybersecurity professionals refer to as an advanced persistent threat (APT) adversary. Such adversaries are typically well-funded and well-organized, which allows them to quickly evolve their tactics to overcome even the most sophisticated cybersecurity defenses.

The C-23 adversary has been known for targeting individuals in the Middle East since at least 2017, with a particular focus on the Palestinian territories.

The latest variants of its Android spyware are most likely distributed via a download link sent to victims as text messages. The link leads to a malicious app that pretends to install legitimate updates on the victim’s mobile device. When the app is launched for the first time, it requests a number of permissions that let it spy on the victim. It then disguises itself to make removal more difficult.

“The new variants use more, and more varied, disguises than previous versions, hiding behind popular app icons such as Chrome, Google, Google Play, YouTube, or the BOTIM voice-over-IP service” explain Sophos. “If targets click a fraudulent icon, the spyware launches the legitimate version of the app, while maintaining surveillance in the background”.

The information the new spyware can steal includes everything from text messages to the names of installed apps to contacts from all kinds of apps, including Facebook and WhatsApp. The spyware can even dismiss notifications and toggle “Do Not Disturb” settings.

Sophos recommends Android users to never install apps from untrusted sources and avoid ignoring available OS and app updates. The company’s own mobile antivirus app, called Sophos Intercept X for Mobile, can detect the new spyware as well as all kinds of other malicious software.
