Cosw Ransomware

The emergence of ransomware has posed a severe threat to the security of computer systems and user data. The Cosw Ransomware is exactly this threat type and it can cause significant damage to the files and data of its victims. Cosw belongs to the STOP/Djvu malware family, and its main objective is to run an encryption process on the affected devices. The threat renames the affected files by adding the '.cosw' extension to their original file names. Additionally, Cosw generates a file called '_readme.txt,' which provides the victim with instructions on how to pay a ransom to receive a decryption tool.

It is crucial to note the cybercriminal operators of Cosw may deploy additional types of malware to the infected systems. Indeed, STOP/Djvu threats have been observed to be accompanied by data-stealing malware such as RedLine or Vidar.

The Cosw Ransomware Seeks to Extort its Victims

Cosw Ransomware's ransom note includes detailed instructions on how to contact and pay the attackers within 72 hours to obtain the decryption tools needed to recover the encrypted files. The note highlights that without the decryption tools, restoring the encrypted files is impossible. The ransom amount is $490, which is half of the $980 fee that victims are warned they will have to pay if they fail to contact the attackers within the given time frame.

In addition to the payment and contact details, the ransom note also states that the threat actors offer to decrypt a single file for free as a way to demonstrate the validity of their claims. To communicate with the attackers and pay the ransom, the victims are provided with two email addresses: support@freshmail.top and datarestorehelp@airmail.cc.

Remember that paying the ransom is not a guaranteed method of recovering the encrypted files, as there have been cases where victims have paid the ransom, but the attackers failed to provide the decryption tool. Therefore, it is recommended that users remain vigilant and take proactive measures to protect their devices and data from ransomware attacks.

By taking these actions, users can help protect their devices and data from ransomware attacks and minimize the impact if an attack does occur.
