Now, a security researcher has spotted another
hacking tool—this time a PHP script—which is freely available on multiple
popular underground hacking forums and allows anyone to find vulnerable
internet-connected IP Cameras running the vulnerable version of GoAhead
embedded web-server.
However, after closely analysing the scanning script, Newsky Security researcher Ankit Anubhav found that the tool also contains a secret backdoor, which essentially allows its creator to "hack the hacker."
"For an
attacker’s point of view, it can be very beneficial to hack a hacker,"
Anubhav said.
"For example,
if a script kiddie owns a botnet of 10,000 IoT and if he gets hacked, the
entire botnet is now in control of the attacker who got control of the system
of this script kiddie. Hence, by exploiting one device, he can add thousands of
botnets to his army."
The rise of IoT botnet and release of mirai’s
source code the biggest IoT Based malware threat that emerged last
year and took down dun DNS service has encouraged criminal hackers to create
their massive botnet either to launch DDoS attacks against their targets or to
rent them to earn money.
As shown in the self-explanatory flowchart, this IoT scanning script works in four steps:
·
First, it scans a
set of IP addresses to find GoAhead servers vulnerable to a previously
disclosed authentication bypass vulnerability in Wireless IP Camera (P2P) WIFI
CAM devices.
·
In the background,
it secretly creates a backdoor user account (username: VM | password:
Meme123) on the wannabe hacker's system, giving the attacker
same privilege as root.
·
Script also extracts
the IP address of the wannabe hacker, allowing script author to access the
compromised systems remotely.
·
Moreover, it also
runs another payload on the script kiddie’s system, eventually installing a
well-known botnet, dubbed Kaiten.
This tool is another example of backdoored hacking
tools increasingly being distributed at various underground forums to hack the
hacker.
In September, a backdoored Cobian RAT builder kit was spotted on multiple underground hacking forums for free but was caught containing a backdoored module that aimed to provide the kit's authors access to all of the victim's data.
