Security researchers: criminals use discord to spread malware

The content delivery network (CDN) of voice and text chat platform Discord is increasingly being abused by criminals to spread malware, according to security researchers. Security firm Sophos writes that four percent of its malware downloads studied came from Discord in the second quarter of this year. Discord allows users to upload and exchange files. This has some advantages for cybercriminals, according to Sophos.

In total, Sophos found 14.000 malicious files on the Discord CDN and sees an upward trend. For criminals to place their malware there, all they need is a chat room that anyone can create for free. As soon as a file is uploaded, it ends up on cdn.discordapp.com. In this Google Cloud Storage, Trojans are then accessible from all over the world via a fast CDN.

Files can be accessed directly

Security researchers: criminals use discord to spread malware

Discord uploads files to its CDN, but no longer looses them.

The special feature: No login is required to retrieve the file. If the URL of the uploaded file is retrieved, the browser will directly ask if the file should be downloaded. If this URL is linked in an email, there is no warning message or anything else that could distract from the download.

Semiconductor supplier asml: production backlog worth 17.5 billion euros

The high global demand for semiconductor components is leading to a sustained high level of sales at the Dutch outfitter ASML: the company took in a good 4 billion euros in the second quarter of 2021, leaving just over 1 billion euros as profit.

ASML sold 69 newly built imaging machines in three months – four fewer than in the first quarter of 2021, when sales were nearly 4.4 billion euros. In both quarters, the manufacturer refurbished three repurchased systems, only to sell them again.

EUV monopoly

ASML is the only supplier offering lithography systems with extreme ultraviolet (EUV) wavelengths of 13.5 nanometers. The world’s largest manufacturers TSMC, Samsung and Intel, as well as memory manufacturers such as Samsung and SK Hynix, rely on the imagesetters.

Ex-vw ceo winterkorn also in court for market manipulation

Former VW CEO Martin Winterkorn must also stand trial on charges of market manipulation. This was announced by the competent chamber of the Regional Court of Braunschweig on Thursday (24 September). Sept. 2020). This means that there will be a criminal trial against the ex-manager not only in a parallel fraud case, but also due to allegedly informing investors too late.

Winterkorn allegedly failed to inform investors in time

The court declared that Winterkorn was to have "despite knowledge of the installation of an inadmissible defeat device (…) and of the considerable financial risk that had been looming since spring 2015 (…), Winterkorn is alleged to have failed to inform the capital market in good time". The Braunschweig public prosecutor’s office’s indictment was therefore admitted to the main hearing without being changed.

Diess and Potsch also accused of market manipulation

The prosecutors had also accused the current Volkswagen Group CEO Herbert Diess and the Chairman of the Supervisory Board, Hans Dieter Potsch, of market manipulation. In their case, however, the proceedings were dropped in return for monetary payments of 4.5 million euros each. Potsch was the carmaker’s CFO at the time the emissions scandal came to light.

Until 1990, so-called aerial flights required a special permit from the authorities. Even though the corresponding regulation no longer exists, it is not allowed to take pictures of everything that comes in front of your lens from above. With a photographic drone in particular, it is easy to get a glimpse of areas that are actually protected from public view. Just as you shouldn’t try to take a snapshot of your neighbor over the fence equipped with a ladder and telephoto lens, you shouldn’t use a multicopter to get around a privacy screen either.

The legal asset that is easily violated in this way is the general right to privacy protected by the General right to privacy. It is divided into intimate sphere, private sphere and social sphere.

Encroachments on the privacy sphere are always illegal. For example, if I fly my multicopter to the third floor of a house and take a picture of a person in the window, the person concerned will be entitled to damages and compensation. In addition, I may even be liable to prosecution. According to Section 201a of the German Criminal Code, the so-called "paparazzi paragraph", The mere taking of a picture that violates the highly personal sphere of the person depicted is prohibited and is punishable by up to two years’ imprisonment or a fine.

India: using internet blocks and twitter blockades against farmers' protests' protests

In the face of weeks of protests by farmers on the outskirts of the Indian capital, local authorities have not only blocked the Internet, but in the meantime have also had hundreds of Twitter accounts suspended. Several districts directly bordering India’s capital territory of Delhi are affected by the internet blackouts, various media outlets report in unison. The Twitter suspensions affected more than 200 accounts accused of inciting violence in connection with the protests, according to the Guardian. Affected accounts include those of news sites, journalists and celebrities.

Peasants vs. Modi

As the British BBC explains, tens of thousands of Indian farmers have been camping outside the Indian capital for weeks. According to the report, they are protesting new laws that have weakened rules on the sale, pricing and storage of agricultural products. Farmers fear for their economic security and their protests represent the biggest crisis of Prime Minister Narendra Modi’s tenure. After all, half the population of the billion-strong nation works in agriculture. But while Modi has offered a suspension of the laws, protesters are demanding their complete repeal.

In India, the authorities always respond to protests with Internet blocks, even if they are then overturned by the courts. Currently, the closures are affecting several districts of the state of Haryana, which directly borders Delhi and where the protesters have gathered. Recently, they were extended by the day, a political solution to the crisis does not seem to be in sight. This is also evident from the immense fortifications with which the security authorities have secured the roads on the Delhi border. The farmers speak of “warlike” Fortifications and photos show immense barricades that appear to be built to last.

Databases: mariadb platform x5 distributes data more flexibly

MariaDB Corporation, the company behind the database of the same name that evolved from MySQL, releases MariaDB Platform X5, a new product version. In addition to a new XPand Smart Engine, the development team behind the MariaDB platform is updating the InnoDB standard engine.

Version X5 of the database platform introduces the Xpand Smart Engine, which is based on a distributed SQL architecture. Xpand is designed to provide more flexibility for horizontal scaling (scale-out). The Xpand engine also distributes table data and indexes across database instances, allowing users to perform distributed queries across all data or individual tables.

Updating the InnoDB Component

The MariaDB platform uses InnoDB as the default engine for transactions. The update provides some updates for this component: Key tuning parameters such as the redo log size and the number of purge threads can apparently now be changed at runtime without requiring a reboot.

Astronomers have found gravitational waves that indicate a collision of a black hole with a still unclear celestial body that does not fit into current theories. The gravitational wave detectors Ligo and Virgo have detected the signals on 14. August 2019 measured, explains the research team, which was coordinated by Vicky Kalogera of Northwestern University. The gravitational waves GW190814 originate from the collision of a black hole of 23 times the mass of our sun and an object of 2.6 times the mass of the sun. This is actually too massive for a neutron star and not massive enough for a black hole.

Neutron star or black hole?

As the researchers now explain, the most massive stars collapse into black holes, while lighter ones explode in supernovae, leaving compact neutron stars behind. But there is a gap between the most massive neutron stars of just over 2 solar masses and the smallest black holes of 5 solar masses. Until now, it was not clear whether there were objects in this gap. However, the amount of mass of the smaller object in the now observed collision is very robust and quite a challenge for astrophysical models. Researchers present their work in the Astrophysical Journal Letters.

The collision was also unusual in that the mass of the two objects differed by a factor of 9. More than any before. According to the report, it occurred at a distance of 780 million light years, too far away for visible traces to reach us. Moreover, the rather massive black hole probably swallowed the smaller object completely, so not much light was emitted anyway. We will probably not learn anything more about the nature of this collision, but astronomers hope for similar collisions in the future.

Data analysis: apache superset 1.0 has reached maturity as a top-level project

The Apache Software Foundation (ASF) has released version 1.0 of Apache Superset. The open source project is designed as a modern business intelligence software that provides comprehensive data exploration and visualization capabilities. With the achievement of the first major release, Apache Superset also appears to have matured to the point where it has joined the ranks of ASF’s top-level projects, of which the organization currently maintains about 200.

Data Science and Business Intelligence

Superset is based on a data science and BI project launched at Airbnb in 2015 that was designed to provide users with the ability to easily explore data from a wide variety of sources and databases and graphically prepare it for analysis. For this purpose, the software provides a comprehensive SQL editor as well as a no-code visualization builder. The data integrated from common SQL or cloud-native databases can thus be displayed via a variety of graphic templates, tracked in interactive dashboards and examined with the integrated SQL Lab.

Apache Superset was accepted into the Foundation’s incubator in 2017. During the preservation phase of the project, the software was already being used by numerous users in various industries – including, in addition to Airbnb, for example, American Express, Dropbox, Lyft, Netflix, Twitter and Udemy.

Oceanbird cargo glider for 7000 cars: first tests

In 2024, the Swedish shipbuilder Wallenius Marine plans to launch the "Oceanbird" Launch a cargo sailer that can transport 7000 cars. The announcement in September of this year was followed by a first practical test on a small scale.

An experiment with a 7-meter boat and a sail was successful, writes Wallenius Marine. Five 80-meter-high sails are to be installed on the ship, which is ultimately planned to be 200 meters long. It will be able to make an Atlantic crossing in twelve days, with emissions savings of 90 percent compared with conventional car transports.

Students from the Swedish Royal Institute of Technology (KTH) love to launch the test boat at the Viggbyholm Boat Club north of Stockholm to study the structure of the wing-like sail, whether its remote-controlled orientation works, and to prepare for rough tests in November. In future prototypes, instead of radio control, a computer will use data from wind sensors, GPS and a compass to decide independently how to adjust the sails and rudder.

Lukas Gawenda has been learning since he was 10 years old. He was able to see the unique interplay of light, time, shapes, and colors through photography before the age of six. From America’s national parks and the Sahara to Iceland’s volcanic landscapes, glaciers and rivers, his images are imprinted with stunning natural landscapes. With his photographs he wanted not only to show the beauty of nature, but also to draw attention to its vulnerability. Lisa Rossbach from seen spoke with Lukas Gawenda.by.

Lukas, you started taking pictures at the age of ten and thus pursued a rather rare hobby in your youth – what got you into photography??

Lukas Gawenda: Strictly speaking, I started taking pictures earlier – I only put the ten years as a rough guide, because I really started at ten years old "consciously" to be photographed. My first experience with analog photography was when I was about three years old, influenced by my father Roland Schweizer, who has been an avid photographer for over 30 years, traveling with his camera, publishing calendars and photo books, and presenting his pictures in multivision shows. My father’s cameras, which were still analog at the time, were practically at my fingertips – I practically grew up with photography.
