What is Sapphire ransomware? And how does it execute its attack?


Sapphire ransomware is a data-Sapphireypting malware design to corrupt important data in a computer, making them inaccessible. According to security experts, this new ransomware threat is based on the Stupid ransomware group. It uses an extension of “.sapphire” in marking the data it encrypts, hence the name.

Once it enters a targeted computer, Sapphire ransomware will drop its malicious payload and connects the system to a remote server. From this remote server, it downloads several malicious components and places them in system folders. After establishing a connection, it employs a data gathering module to collect information about the system and its user. The information gathered, along with the added malicious files are then used for the stealth protection module which protects the crypto-malware from and prevents any program installed in the system from interrupting its attack.

Moreover, it also makes changes in the Windows Registry by modifying some registry entries and keys as well as create new ones – this is done to make sure that Sapphire ransomware can run on every system boot automatically. Following system modification, Sapphire ransomware will start encrypting files using a sophisticated encryption algorithm. After the encryption, it appends the “.sapphire” extension to each one of the encrypted files and opens a program window that contains its ransom note stating:

“Sapphire Ransomware

been Sapphireypted by Sapphire! I’m in a good mood today and
