A new malware called EternalRocks was discovered in late May that uses not only EternalBlue and DoublePulsar—the two National Security Agency (NSA) exploits leaked by the ShadowBrokers hacking group and used by the notorious WannaCry ransomware—but five other exploits and tools similarly leaked by the same group: EternalChampion, EternalRomance, EternalSynergy, ArchiTouch and SMBTouch. Most of these exploits target the MicrosoftServer Message Block (SMB), which handles access sharing between nodes on a network.
