Some HammerDuke\r\nvariants only contain a hardcoded C\u0026C server address from which they will retrieve commands, but other\r\nHammerDuke variants will first use a custom algorithm to generate a Twitter account name based on the current\r\ndate. If the account exists, HammerDuke will then search for tweets from that account with links to image files\r\nthat contain embedded commands for the toolset to execute.\r\nReferences\r\nThere is no Yara-Signature yet.\r\nSource: https://malpedia.caad.fkie.fraunhofer.de/details/win.tdiscoverer\r\nhttps://malpedia.caad.fkie.fraunhofer.de/details/win.tdiscoverer\r\nPage 1 of 1",
