X-Agent or XAgent is a spyware and malware program designed to collect and transmit hacked files from machines running Windows, Linux, iOS, or Android, to servers operated by hackers. It employs phishing attacks and the program is designed to "hop" from device to device.[2][3][4] In 2016, CrowdStrike identified an Android variant of the malware for the first time, and claimed that the malware targeted members of the Ukrainian military by distributing an infected version of an app to control D-30 Howitzer artillery.[1] The Ukrainian army denied CrowdStrike's report and stated that losses of Howitzer artillery pieces had "nothing to do with the stated cause".[5]

Slovak computer security company ESET obtained the X-Agent source code in 2015 and described its inner workings in a report released in October 2016.[6]

A Washington, DC grand jury indictment (resulting from Robert Mueller's investigation into Russian election interference) charges that agents of the Russian GRU in Moscow "developed, customized and monitored X-Agent malware used to hack the DCCC [Democratic Congressional Campaign Committee] and DNC [Democratic National Committee] networks beginning in or around April 2016" (item 15, at the end of page 4 and the beginning of page 5).[7]
