Internet-of-Things (IoT) based very dangerous Mirai Botnet attack rapidly raised again in South America and North Africa countries that were detected by increasing the huge Traffic on ports 2323 and 23.
Mirai is a malware that turns networked devices running Linux into remotely controlled “bots” that can be used as part of a botnet in large-scale network attacks. It primarily targets online consumer devices such as IP cameras and home routers.
The DDoS bots used in the attack were hiding behind different user-agents than the five hardcoded in the default Mirai version.This–and the size of the attack itself–led us to believe that we might be dealing with a new variant, which was modified to launch more elaborate application layer attacks.
This newly emerging Mirai Attack mainly targeting IP cameras, digital video recorders (DVRs), network video recorders (NVRs), as well as modems.
some of detected IoT attack attempt by this new ware of Mirai.

Recent of Series Mirai attempt Detected in Colombia, Ecuador, Panama, Egypt, and Tunisia, as well as more activity in Argentina.
Colombia is the main target for this Mirai bots and the second wave of attack attempts, with Ecuador, Argentina, Egypt, and Tunisia showing similar patterns.
End of the November 2017, it Rose the number of botnet counts raipdly and 371,640 attack attempts were detected coming from roughly 9,000 unique IP addresses.
This attempt frequently attempting the botnet attacks first wave (Argentina) and the second wave (Colombia and Panama):
First attempt started on November 22, as we see in the first graph shows Argentina was the first wave of targeting.
This attempt keeping running until hitting below 1000 attempt and the second wave of attack attempts started on November 29.
the second wave of attack in Colombia is, even more, higher than Argentina hits and the highest recorded single-hour attack attempts occurring in Colombia (80,825 at 19:00 UTC).
Mirai IP tracking report revealed that most of the attempt has been registered from same region and attacker mostly located in the same area.
Apart from this Attacker attempting this distribution into five primary countries that were the main focus of the second wave.
The first wave of attempt that was started on Nov 22 has peaked at 24,716 hits but the second wave of attempt peaked at 56,748 in a single hour on November 29.
According to Trend Micro Report, the attackers are still trying to exploit ZyXEL modems as entry points using Mirai Botnet, along with other devices that were not seen in the earlier attacks targeting Argentina – in particular, the Tenvis TH692 Outdoor P2P HD Waterproof IP Camera.
Security Expert still analyzing this two wave are connected or not continuously monitoring the attempt this Mirai Attack in the Different region.
