Osdè, one of the largest prepaid in the country, suffered a cyber attack in the early hours of Saturday. The site stood idle for a few hours and did not allow its partners to carry out operations, but was soon restored.
While the attack lasted, the certificate SSL appeared crossed out in the address bar, giving an error due to an invalid problem or expiration date. This is a certification that guarantees that the connection between the user and the server is encrypted.
The situation was noticed by some users who wanted to manage the procedures from the web and could not access.
The attack It was confirmed on Monday, when the company issued a statement. There they say: “The corresponding protocol was activated immediately for these cases and for this some of our systems were affected.”
Because of these types of attacks, both of them the application such as the web may have trouble working. At the moment the systems are restored and can be accessed.
Some versions indicate this it’s about lockbit, one of the most prominent ransomware groups this year, which uses this type of program to encrypt information and demand a ransom in exchange. This group attacked Ingenios Ledesma this year, in March.
However, there is no information posted on the cybercriminals’ website. This may mean that they are uploading the information or negotiating with the company not to publish the stolen data.

What is ransomware
Ransomware is a type of program that encrypts information to extort money from users. Its name stands for “data ransomware”: ransom in English means ransom and ware is an abbreviation of the well-known word software: a data hijacking program. Ransomware is a sub-type of malware, which stands for “malicious software”.
Now, this type of program works by limiting access to parts of our personal information, or all of it. And in general, hackers use it to ask for something in return: money.
While some simple ransomware can lock down the system in an easy way, more advanced ransomware uses a technique called “cryptoviral” extortion, in which the victim’s files are encrypted, making them completely inaccessible.

In recent years, this form of extortion has become very popular with cybercriminals, putting business giants like Nvidia, Samsung, Capcom, Microsoft and Apple into trouble all over the world.
Locally, Mercado Libre, Globant and even Ingenio Ledesma fell prey to this type of extortion.
Even the Argentine state was not immune: in 2020, cybercriminals from a gang called Netwalker published sensitive data from Migrations of Argentina.
And in January of this year, the Senate of the Nation suffered a massive private data leak.
