Demonstrator masters flight sequences for reusable rocket stages
The demonstrator technology vehicle (DTV) is a 60 kg platform with landing legs. It has been developed by INCAS, Romania’s National Institute for Aerospace Research in Bucharest. DTV’s turbo jet 0.9 kN-class engine provides the power to carry payloads totalling 20 kg. Tests at INCAS in July 2020 lasted ten seconds to a couple of minutes to demonstrate vertical takeoff, short hovering and landing manoeuvres – the technology building blocks for the recovery of a rocket stage. This project was carried out with the support of ESA’s Future Launchers Preparatory Programme. Credit: ESA

A crucial part of rocket reusability is a smooth return and landing. ESA has helped Romania’s National Institute for Aerospace Research, INCAS, to demonstrate vertical takeoff, short hovering and landing maneuvers using a small-scale flight demonstrator.

Prominent Stages In The Evolution Of Ransomware

At its rudimentary stage, online extortion was all about bluff and did not use cryptography at all. It hinged upon screen lockers stating that the FBI caught users violating copyright or distributing NSFW content. Victims were instructed to pay a fine via a prepaid service such as MoneyPak or Ukash.

Things have changed dramatically over time. Ransomware operators rethought the range of their intended victims, switching to the enterprise as juicier prey than individuals. In recent years, they also added a data leak strategy and DDoS threats to their genre. As a result, online extortion has matured into one of today’s most detrimental cybersecurity perils.

Ransomware went pro in 2013

The first mainstream file-encrypting ransom Trojan called CryptoLocker made its debut in September 2013. It used an asymmetric 2048-bit RSA cipher
