Background introduction
On August 26, 2019, our 360Netlab Unknown Threat Detection System highlighted a
suspicious ELF file (4cd7bcd0960a69500aa80f32762d72bc) and passed along to our
researchers to take a closer look, upon further analysis, we determined it is a
P2P bot program.

Fast forwarded to October 11, 2019, our Anglerfish honeypot captured another
suspicious ELF sample (4b98096736e94693e2dc5a1361e1a720), and it turned out to
be the Downloader of the previous suspicious ELF sample. The Do

Jetpack 7.9.1 contains a critical security update. You should update all sites that you administer as soon as possible.
