Static analyses are simplistic, fast, and resource friendly. Behavioral analyses are more thorough but also more resource intensive. There will be more failed connection attempts for the same reason and those connection attempts are more likely to involve numerical IP addresses than server names. And, of course, port-scanning the local network for new infiltration opportunities is classic behavior for a bot. One slightly newer wrinkle for botnets is a P2P management architecture.
Such a botnet is harder to detect, though infected bots will usually act in much the same ways otherwise because the bot herder has the same goals. As botnets have evolved, so have the tools to detect and eradicate them. Today, focused open-source solutions like Snort and more comprehensive, integrated security intelligence offerings from providers like AlienVault are available to:.
And going forward, such solutions are only getting smarter — fast. This is happening in a variety of ways, some tech-centric such as machine learning as implemented for botnet pattern recognition , some human-centric and some that combine the two.

Botnet detection: Ferreting out one or more bots on your network Initial signs and symptoms There are several symptoms which often manifest shortly after botnet infiltration as the compromised machine begins executing its instructions.
Botnet detection at the endpoint Host-based botnet detection begins with client-side anti-viral solutions, since the infiltration itself nearly always happens via malware. Botnet detection on the network Network-based botnet detection is a bit more complex. Botnet detection via honeypot Especially ambitious security professionals may consider creating a honeypot false infiltration opportunity and seeing if it, indeed, becomes infiltrated — and if so, how.
In , the crooks repurposed this botnet so that it mainly acts as a loader for other malicious applications. For instance, Emotet often operates in tandem with the notorious enterprise-targeting ransomware called Ryuk.
In , researchers unveiled a new feature of Emotet: it exhibits worm-like characteristics by hacking poorly secured Wi-Fi networks and self-replicating inside them. As far as the propagation geography goes, the hardest-hit countries are Germany, the U.
Emotet is still going strong in , and so the big picture is constantly changing. This one represents the cluster of click fraud botnets. Of course, this activity was covert, and the user was not likely to notice anything fishy going on. The malicious code also included complex AV evasion mechanisms to stay undetected and bring its proprietors a maximum profit.
The criminals slipped up in when they started faking Border Gateway Protocol BGP communications and tried to obfuscate fraudulent activity by using ranges of IP addresses that belonged to real clients. The foul play was attributed to eight individuals, with 13 criminal cases opened during the investigation.
Mirai is the king of botnets that zero in on IoT devices. Although it came to a standstill a while ago, its numerous spin-offs continue to give white hats a hard time.
First spotted in , it rapidly subdued an army of smart home appliances and other connected devices that used weak passwords. This botnet was masterminded by students who probably bore a grudge against their university and decided to shell it with DDoS attacks.
However, their plot got out of hand at some point, and now Mirai is the largest IoT botnet out there, considering all of its clones. The number of botnets based on it - and its near replicas - has exceeded a hundred and keeps growing. Criminals swamped multiple servers around the world, which temporarily disrupted such services as Twitter, GitHub, and Spotify. Although the attack weaponized only about , thousand IoT devices, it generated an impressive traffic flood exceeding 1Tbps. Powerful botnets come and go.
As soon as information security professionals and law enforcement agencies shut down a botnet, it is superseded by a new, possibly much more dangerous one. For the average user, the main takeaway from this wicked trend is that password hygiene and timely operating system updates are now more important than ever. These simple precautions can prevent a computer, a router, or smart devices from joining a network operated by cybercrooks.
