It was 100% smoke, but it caught thousands of cryptocurrency investors making up using an AI algorithm: they ended up in the hot seat

In recent years, cryptocurrencies have gained popularity not only as an alternative means of saving and payment, but also as a form of investment… and, with it, an option to obtain substantial profits. This, of course, has attracted all kinds of cyber-swindlers who have jumped on the wave of ‘crypto’.

One of the most prominent cases of this in recent times, at least in Spain, is that of arbistara cryptocurrency investment platform that promised great benefits (8%-15% per month) thanks to the use of an artificial intelligence algorithm called ‘Community Bot’.

Thus, the only condition for investors was that they could not withdraw their money in the first two months, but now we know that, during a period of just over a year (between May 2019 and September 2020), the platform only dedicated itself to defrauding more than 92 million euros from more than 32,000 investors (of which so far it has been possible to identify just over 5,000).


Curiosity: the Arbistar app is still available in the Google Play Store, although it hasn’t been updated for three years.

This is how the ‘shepherd’ was set up

Therefore, yesterday the judge of the National Court José Luis Calama prosecuted seven alleged members of Arbistar for crimes of criminal organization and massive fraud, imposing a joint and several bail of €123 million (on suspicion that the amount defrauded could greatly exceed the 92 million found so far).

However, the most notable thing about the judge’s order is that it establishes that ‘Community Bot’ never existed and that the platform only sold smoke.

55 of Arbistar’s investors invested more than €50,000, and 17 invested more than €250,000

All those unfulfillable profits were actually coming out of a classic pyramid scheme., in which part of the money from new investors was used to pay off previous investors and build trust in the system. Of course, the ‘shack’ would only work as long as the rate of entry of new investors was greater than the mass of pre-existing investors.


For a time they focused on creating a powerful acquisition network, with which they were able to generate an image of profitability and implement a referral plan in which investors received compensation for attracting new clients.

They added to this an effective presence on social networks and the holding of public promotional events in hotels and conference rooms to attract more people.

According to the judge, the undisputed leader of the plot was Santiago Fuentes Jover: he has also determined that Jover was the one who designed the fraudulent strategy and gave instructions to keep it going both to the employees of the company and to the rest of those involved.

This open-source tool allows you to scale any image and video for free with AI: this is how Video2X works

if what you are looking for a free and easy to use tool for scaling images and videos, you have come to the right place. And it is that the app that we are going to talk about next is open source and it makes use of your computer’s hardware to increase the resolution of any image or video, very useful for those occasions in which we have photos or videos of better quality.

Video2X makes use of the capabilities of our graphics card to scale images and videos in poor quality. Besides, supports multiple formats, so it will be very useful to also scale GIFs or videos in MP4, MKV and more formats. Under these lines we show you how it works.

A free tool to scale images and videos

To use this tool, all you have to do is go to its official Github page and download its latest version. Once the ZIP file is obtained, we unzip and we will have a folder with two executable files and other dependencies. In our case we will choose the file ‘video2x_gui.exe‘, since it has a graphical interface to proceed with the scaling.

If you look closely, you will find a lot of options. However, the tool works without applying any initial configuration. Just select the file from your computer via the ‘Select File’ option and then select the output path of the file from the ‘Output’ section. You can also modify the output name in the bottom text box.

After having configured the previous steps, we select ‘Start’ and the process will start automatically. You should know that the scaling process will be long, especially for videos, since it makes use of our graphics card for it. Even if you have a decent graphics card (in our case we used an RTX 3080), depending on the size of the video it could take several hours.

To testify to the qualities of this tool, its creators have uploaded several videos on YouTube that show the quality of the scaling, like this trailer for ‘Spirited Away’, which goes from 360p to 4K.

To scale the files, Video2X makes use of various techniques and algorithms. Through its documentation we can obtain information about which technique to use when scaling a file. For example, if we use ‘Anime4K’, the process will be faster than if we select ‘Waifu2x’, although the quality will be lower. However, if we use ‘realsr-ncnn-vulkan’, the process will be extremely slow, but the quality will be much better.

This powerful AI can restore any photo for free and scale its resolution: that's how it works


The techniques described above rely on frame interpolation processes, machine learning and artificial intelligence, which is why good hardware is required to complete the scaling efficiently. However, in case we do not have a decent graphics card, we can always make use of Google Colab and use a powerful graphics through the cloud to carry out the process.

Although we have mentioned before that the tool works without the need to enter the configuration section at any time, it is worth taking a look at all the options, since we will find sections to modify the level of noise applied, the size, quality and cropping of the file and much more. These options can be modified for each driver used.

This app beeps every time your browser sends data to Google. And it’s non-stop

Bert Hubert —developer, creator of PowerDNS and online privacy activist— has presented an application with which he intends to show how much data our computer sends to Google throughout a browsing session. And, so that we keep it in mind at all times, and we can relate what kind of actions trigger said shipments, alerts us by beeping every time this happens.

That e-mail that has come to you asking for a quote is the first step in a cyberattack

The Central Information Security Brigade of the National Police has issued an alert about a recent wave of cyberattacks directed against Spanish architecture companies (but which “may expand to other sectors in the future”) through a ransomware campaign that they describe as “of high sophistication”.

This attack, which resorts to spoofing, is using Scam emails posing as Fotoprix companya well-known photographic company.

Cyber ​​criminals send messages from a fake domain, “”, requesting budgets for reforms in their facilities. The sophistication of this strategy lies in the fact that the messages are extremely consistent and appear to be legitimate, which reduces the suspicions of the victims.

After several email exchanges, the attackers propose to set up a meeting to finalize the budget. However, before the meeting, they send the victims an attachment containing details about the alleged reform.

By downloading and running this file In their systems, company terminals are automatically encrypted, leaving victims without access to their files and data.

Once the files are encrypted, cybercriminals demand a rescue to unlock the data. Instructions for making the ransom payment are included in a text file that is copied to affected systems.

This extortion tactic is characteristic of other ransomware attacks, where attackers seek financial gain in exchange for restoring access to victims’ files.

The high level of sophistication of the campaign makes it difficult for victims to suspect the hoax until they have already been affected.



Tips to consider

The Central Cybercrime Unit of the National Police continues to work to track and contain this threat, but it is essential that companies remain vigilant and take proactive measures to protect themselves against these types of increasingly sophisticated cyberattacks.

Faced with this situation, the Police have developed the following basic recommendations to avoid being a victim of these attacks:

  1. Beware of unknown emails: Do not open e-mails from unknown senders or those that have not been previously requested.
  2. Avoid suspicious downloads: Do not download email attachments from unknown senders.
  3. Keep systems up to date: Always keep the operating system and antivirus software updated to mitigate possible vulnerabilities.
  4. Make backups: Make backup copies periodically and in independent systems, so that in the event of an attack the data can be recovered without the need to accept the payment of any ransom.
