In March 2017, Kasperksy released a report that compared DROPSHOT (which they call Stonedrill) with the most recent variant of SHAMOON (referred to as Shamoon 2.0). They stated that both wipers employ anti-emulation techniques and were used to target organizations in Saudi Arabia, but also mentioned several differences. For example, they stated DROPSHOT uses more advanced anti-emulation techniques, utilizes external scripts for self-deletion, and uses memory injection versus external drivers for deployment. Kaspersky also noted the difference in resource language sections: SHAMOON embeds Arabic-Yemen language resources while DROPSHOT embeds Farsi (Persian) language resources.
