Good deed ransomware virus

03.06.2022

CloudSEK cybersecurity experts spoke about the GoodWill hacker group, which distributes a ransomware virus, but in order to decrypt the data, it requires the victim not to pay a ransom, but to do good deeds. For example, donate blankets to the homeless, feed starving children with fast food, or pay for treatment for the poor, capture all this on photos and videos, and then post them on social networks.

According to experts, the ransomware operators work from India - this is indicated by their emails and IP addresses assigned to Mumbai, to which the virus accesses. In addition, in one of the lines of code, an entry was found in "Hinglish" - a mixture of Hindi and English. The malware is written in the .NET framework, compressed with the UPX executable file packer, and data on infected Windows machines is encrypted using the AES algorithm.

After infecting the victim’s PC, the GoodWill virus encrypts files of various formats on it and offers to do three good deeds to decrypt them: donate clothes or blankets to the “needy on the road”, take five poor children to a fast food establishment, and also visit the nearest hospital and pay for treatment to a person who who are unable to do so on their own.

The first two actions must be documented on social networks using the photo frame offered by the hackers, and the last one should be taken with the object of help and sent along with the audio recording of the conversation with this person to the operators of the ransomware virus. After completing these three good deeds, you need to write and post on the social network an article on the topic "How you became a kind person, being a victim of the GoodWill ransomware virus." After that, the hackers allegedly send a tool to decrypt the data.

Experts have discovered a connection between GoodWill and a sample of experimental malware HiddenTear, which was developed and placed on GitHub by a certain Turkish programmer for security reasons. CloudSEK reported that 91 of GoodWill's 1246 lines of code match the HiddenTear sample.

Machine for thinning flowers in gardens 02.05.2024

In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers. ... >>

Advanced Infrared Microscope 02.05.2024

Microscopes play an important role in scientific research, allowing scientists to delve into structures and processes invisible to the eye. However, various microscopy methods have their limitations, and among them was the limitation of resolution when using the infrared range. But the latest achievements of Japanese researchers from the University of Tokyo open up new prospects for studying the microworld. Scientists from the University of Tokyo have unveiled a new microscope that will revolutionize the capabilities of infrared microscopy. This advanced instrument allows you to see the internal structures of living bacteria with amazing clarity on the nanometer scale. Typically, mid-infrared microscopes are limited by low resolution, but the latest development from Japanese researchers overcomes these limitations. According to scientists, the developed microscope allows creating images with a resolution of up to 120 nanometers, which is 30 times higher than the resolution of traditional microscopes. ... >>

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

The threat of space debris to the Earth's magnetic field 01.05.2024

More and more often we hear about an increase in the amount of space debris surrounding our planet. However, it is not only active satellites and spacecraft that contribute to this problem, but also debris from old missions. The growing number of satellites launched by companies like SpaceX creates not only opportunities for the development of the Internet, but also serious threats to space security. Experts are now turning their attention to the potential implications for the Earth's magnetic field. Dr. Jonathan McDowell of the Harvard-Smithsonian Center for Astrophysics emphasizes that companies are rapidly deploying satellite constellations, and the number of satellites could grow to 100 in the next decade. The rapid development of these cosmic armadas of satellites can lead to contamination of the Earth's plasma environment with dangerous debris and a threat to the stability of the magnetosphere. Metal debris from used rockets can disrupt the ionosphere and magnetosphere. Both of these systems play a key role in protecting the atmosphere and maintaining ... >>

Solidification of bulk substances 30.04.2024

There are quite a few mysteries in the world of science, and one of them is the strange behavior of bulk materials. They may behave like a solid but suddenly turn into a flowing liquid. This phenomenon has attracted the attention of many researchers, and we may finally be getting closer to solving this mystery. Imagine sand in an hourglass. It usually flows freely, but in some cases its particles begin to get stuck, turning from a liquid to a solid. This transition has important implications for many areas, from drug production to construction. Researchers from the USA have attempted to describe this phenomenon and come closer to understanding it. In the study, the scientists conducted simulations in the laboratory using data from bags of polystyrene beads. They found that the vibrations within these sets had specific frequencies, meaning that only certain types of vibrations could travel through the material. Received ... >>

Panasonic Lumix DMC-FZ70 60x optical zoom camera 05.08.2013

Panasonic has announced the addition of the DMC-FZ70 to its Lumix range of digital cameras. Equipped with a 20mm to 1200mm equivalent focal length lens, this camera's 60x optical zoom is more than double that of its predecessor, the Lumix DMC-FZ60. The optical scheme of the lens includes 14 elements in 12 groups, among them six are aspherical, and three are made of low dispersion glass. As for the maximum aperture of the lens, it varies from F / 2,8 to F / 5,9.

It goes without saying that with this optical zoom, the camera is equipped with an optical stabilization system that also works when shooting video. The Panasonic Lumix DMC-FZ70 uses a 1/2,3-inch CMOS image sensor with a resolution of 16,8 MP and a Venus Engine image processor. The camera allows continuous shooting at 9 frames per second in maximum resolution and Full HD video recording at 30 frames per second.

The novelty supports iA intelligent shooting mode, and also allows you to apply 15 different effects to photographs. It also supports saving pictures in RAW format.

The Panasonic Lumix DMC-FZ70 is equipped with a 3-inch display with a resolution of 460 dots, the amount of integrated flash memory of the product is 000 MB. It is supposed to use SD, SDHC or SDXC cards as the main data storage. The camera is equipped with a USB port and a Mini HDMI video output.

Overall dimensions of new items - 130 x 97 x 118 mm, weight - 606 grams. The battery life of the camera, measured according to the CIPA standard, is 400 shots.

The Panasonic Lumix DMC-FZ70 is priced at $399 in the US.
