Arrival Details
This Backdoor arrives on a system as a file dropped by other malware or as a file downloaded unknowingly by users when visiting malicious sites.
Installation
This Backdoor drops the following files:
- /{malware path}/Dest.cfg
- /{malware path}/appq.log
- /{malware path}/conf.n
- /user/bin/bsd-port/knerl.conf
- /user/bin/bsd-port/udevd.conf
- /usr/lib/libamplify.so - list of IP addresses used for its DDoS capabilities
- /tmp/notify.file
- /proc/net/pktgen/kpktgend_{number}
- /proc/net/pktgen/eth_{number}
- /proc/net/pktgen/pgctrl
It drops the following copies of itself into the affected system:
- /usr/bin/lsof
- /usr/bin/.sshd
- /user/bin/bsd-port/knerl
- /user/bin/bsd-port/udevd
It creates the following folders:
- /usr/bin/dpkgd
