Malware Alert: Mirai Alias Miori Is Being Dispensed Via RCE Exploits


To
add on to the latest list of raging malware, the cyber-cons decided on changing
names of some older ones.

Malware
Mirai, is now being dispensed by the name of Miori, by way of malicious remote
code execution exploits.
The Mirai Malware has a really solid history of wreaking
havoc by executing DDOS (Distributed Denial of Service) attacks on various
platforms among IoT devices.
The botnet in question has previously executed some truly jeopardizing
DDOS attacks and has been the culprit for computer fraud and abuse.
The malware would need to function equally well on different
architectures in order to run on cross-platforms.
Now, Miori can easily exploit internet connected devices by
abusing their vulnerabilities. The smart devices are always on the radar for
this malware.
The above-mentioned malware is being dispensed through
Remote Code Execution vulnerability in the PHP structure of the name ThinkPHP.
The exploit especially has targeted, versions previous to 5.0.23 and 5.1.31.
 The security
researchers who are on to the malware, have alluded that the rate of infection is
increasing in the case of ThinkPHP RCE in smart devices.
Numerous other Mirai malware which exploit the ThinkPHP RCE vulnerability
are also being dispensed.
Researchers also confirmed that a Linux device was made to
perform the DDOS attack because of the infection dispensed via other connected
devices as the default credentials got reset through a telnet.
Reportedly, Miori is merely a subdivision which the
cyber-cons use to fabricate vulnerable devices via Thinkpad RCE.
The malware variant could be downloaded from the following
command and control server. Hxxp://144[.]202[.]49[.]126/php
Once the malware is executed a console gets generated which switches
the Telnet on, to brute force other IP addresses.
On the port 42352 (TCP/UDP) the C&C server keeps a check
to receive further commands.
The configuration table, of the Miori malware was de-crypted
by researchers, which was instated in its binary strings.
The username passwords and other credentials which were used
by the malware were also found out by the researchers as they were fairly easy
to speculate.
A scrutinized look resulted in the discovery of two URLs
that were employed by the two variants of Mirai, namely APEP and IZIH9. Both were
employing the same string  anti-obfuscation procedure as Miarai and Miori.
APEP also spreads by exploiting CVE-2017-17215 which
encompasses of one other RCE vulnerability which can seriously affect router
devices.
