What is EMBARGO Ransomware?
EMBARGO is a form of ransomware, a malicious software designed to encrypt files on an infected device. This particular ransomware changes file names by appending a random extension and creates a ransom note named "HOW_TO_RECOVER_FILES.txt". For instance, it might rename "1.jpg" to "1.jpg.564ba1" and "2.png" to "2.png.564ba1".

The Ransom Note
The ransom note from the EMBARGO ransomware claims that the attackers have infiltrated the network, downloaded sensitive documents, and encrypted the system. It instructs the victim to contact the attackers before a specified deadline to decrypt the system and prevent the disclosure of sensitive information. The note includes a link to download the Tor browser and register an account, and warns against modifying files. It provides instructions for contacting the attackers and promises a decryption tool upon payment.
The EMBARGO Ransomware note reads like the following:

Understanding Ransomware
Ransomware encrypts files on a computer, making them inaccessible until a decryption tool is used. Typically, only the attackers can provide this tool. Paying the ransom is risky because there is no guarantee that the attackers will deliver the decryption tool. Sometimes, free decryption tools are available online, and files can be restored from backups, avoiding the need for payment. Removing the ransomware is crucial to prevent it from spreading to other computers on the network or encrypting more files on the same system.
General Ransomware Characteristics
In ransomware attacks, files are encrypted using strong cryptographic algorithms, and attackers demand payment in cryptocurrency for the decryption tools. Victims receive instructions on how to communicate with the attackers and make the payment. Various ransomware variants exist, such as ZHO, OCEANS, and GhosHacker. Regularly backing up files to remote servers or disconnected storage devices is essential to recover data without paying a ransom in case of an attack.
Infection Vectors
Ransomware spreads through various methods, including malicious emails with attachments or links, vulnerabilities in outdated operating systems or software, pirated software, and infected cracking tools or key generators. Users might also infect their computers through malicious online advertisements, fake system updates, downloads from peer-to-peer networks, third-party download platforms, technical support scams, and compromised USB drives. Cybercriminals use diverse file formats for deploying malware, such as malicious PDFs, executable files, MS Office documents, script files, archives, and ISO files.
Protecting Against Ransomware
To protect against ransomware infections, keep your operating system, web browsers, and software up to date. Use trusted antivirus and anti-malware software, and avoid opening email attachments or links from unknown or suspicious sources. Download software only from official websites or app stores, and avoid peer-to-peer networks, shady websites, third-party downloaders, and pirated software. If your computer is already infected with EMBARGO, run a scan with an anti-malware program to remove the ransomware.
