Malware and Vulnerabilities The main module spreads on the network under various names ("xsvc.exe," "zsvc.exe") and uses a different packer that depends on an external file to be properly unpacked. Download Cyware Social App worm-like infection that keeps spreading itself requires little effort for multiplying returns SMB also enables computers to share printers and serial ports from other computers within the same network.In 2017, the WannaCry ransomware attack exploited a vulnerability in SMB version 1.0 to install malware on vulnerable clients and propagate it across networks.The U.S. National Security Agency discovered the vulnerability in the Windows implementation of the SMB protocol.

Apart from organizing the tools by their purpose in the attack, it also features anti-detection and analysis evasion attributes.Its author added layers of obfuscation from early versions of the bot, which grew more complex in later variants. "In addition to making manual analysis more difficult, this anti-analysis technique also avoids detection in dynamic automated analysis systems" - Furthermore, Prometei can communicate with the C2 server using TOR or I2P proxies, too, to get instructions and send out stolen data.The researcher says that the main module can also double as a remote access trojan, although the main functionality is Monero mining and possibly stealing Bitcoin wallets.Prometei victims are located in the United States, Brazil, Pakistan, China, Mexico, and Chile. There have been a couple different versions of SMB/CIFS over the years. In four months, they earned the threat actor less than $5,000, or an average of $1,250 a month.Based on the methods used to spread across the network and the modules employes, Svajcer believes that behind Prometei may be a professional developer likely from Eastern Europe.Bleeping always used to reference the original article. The EternalBlue exploit kit was however stolen by the Shadow Brokers hacking group who later leaked the exploit kit … Server Message Block (SMB) is a file sharing protocol that allows Windows systems connected to the same network or domain to share files. In domain security mode, the Samba server has a machine account (domain security trust account) and causes all authentication requests to be passed through to the domain controllers.

However, instead of reporting the vulnerability to Microsoft, it developed an exploit kit dubbed ‘EternalBlue’ to exploit the vulnerability.The EternalBlue exploit kit was however stolen by the Shadow Brokers hacking group who later leaked the exploit kit on April 08, 2017. EternalBlue exploits the SMB vulnerability. Run the following command to use the smb2-security-mode script against port 445/tcp of the target host: nmap –script smb2-security-mode.nse -p445 It will then provide information about the service. The discovered passwords are sent to the C2 and then reused by other modules that attempt to verify the validity of the passwords on other systems using SMB and RDP protocols”Tracking the botnet’s activity, the researchers noticed that its modules fall into two categories that have fairly distinct purposes: mining-related operations (dropping the miner, spreading on the network) and gaining access by brute-forcing logins using SMB and RDP.Cisco Talos malware researcher Vanja Svajcer says that while the distinct functions and programming language (C++ and .NET) for these modules may indicate that another party is taking advantage of this botnet, it’s more likely that a single actor is controlling all of them.Prometei is stealing passwords with a modified version of Mimikatz (miwalk.exe).
