I do like your use of a context manager with open Your code is neatly written. You are on a good path to learning Python. Good luck! Thanks for the reply, Jim!

When first observed back in January of , GandCrab spread through malicious ads aka malvertising and bogus pop-ups served up by compromised websites. Upon landing on a malicious site, victims would receive an on-screen alert prompting them to download a missing font.
Doing so would install the ransomware. At the same time as the font infection campaign, GandCrab also spread via malware-laden email attachments aka malspam spewed out from a botnet of hacked computers botnets are also used for DDoS attacks.
For most of its short yet destructive run, however, GandCrab typically spread from one computer to the next via something known as an exploit kit. Exploits are a form of cyberattack that takes advantage of weaknesses or vulnerabilities on a target system in order to gain unauthorized access to that system. An exploit kit is a plug-and-play package of various technologies designed to take advantage of one or more exploits.
The Malwarebytes Labs team reported on at least four different exploit kits being used to spread GandCrab, which you can read about here , here , and here. In February of , a month after GandCrab was first spotted in the wild, cybersecurity company Bitdefender released a free GandCrab decryption tool. As it stands the newest version of the decryption tool works on GandCrab versions 1, 4, 5. To this day, there is no free decryption tool available for GandCrab versions 2 and 3.
In response, the GandCrab crew released the decryption key for any GandCrab victims located in Syria and added Syria to the list of countries not targeted by the GandCrab ransomware. They want dollars to give me back my children, that's what they've done, they've taken my boys away from me for a some filthy money. How can I pay them dollars if I barely have enough money to put food on the table for me and my wife? With this kind of attack, the perpetrators scan a given network for systems that are set up for remote access; that is, a system that a user or administrator can log in to and control from another location.
Once the attackers find a system setup for remote access, they will attempt to guess the login credentials using a list of common usernames and passwords aka a brute force or dictionary attack. Thanks to its army of affiliates, diverse attack methodology, and regular code revisions, GandCrab quickly became the most common ransomware detection amongst business and consumer targets for , as reported in the Malwarebytes Labs State of Malware report.
In spite of its success, or perhaps because it, GandCrab called it quits in May of —a year and a half after launching. Best Bluetooth Headphones for Switch. Best Roku TV.
