What Is A BotNet?

A botnet is a network of compromised computers or devices, often referred to as “bots” or “zombies,” which are controlled remotely by a cybercriminal or attacker. These bots are typically infected with malicious software (malware) that allows the attacker to take control of the infected devices without the owners’ knowledge.

Botnets can be used for various malicious activities, including:

1. Distributed Denial-of-Service (DDoS) Attacks: The botnet can be used to flood a target server or website with traffic, overwhelming its resources and causing it to crash or become unavailable.
2. Spam and Phishing Campaigns: Botnets can send out massive volumes of spam emails or phishing messages, often to steal sensitive information such as usernames, passwords, or financial data.
3. Data Theft: Attackers can use botnets to steal personal or financial data from infected devices, often through keylogging or other forms of surveillance.
4. Cryptocurrency Mining: Cybercriminals can hijack the processing power of infected devices to mine cryptocurrencies, which can be highly profitable.
5. Credential Stuffing: Botnets can automate the process of trying stolen usernames and passwords on various websites, attempting to gain unauthorized access to accounts.

Botnets can consist of hundreds, thousands, or even millions of infected devices, which makes them particularly powerful and difficult to combat. These devices can include computers, smartphones, IoT devices (such as cameras, smart thermostats, etc.), and more.
In some cases, botnet operators rent out or sell access to their botnets, allowing other criminals to carry out attacks for profit.

Botnets are illegal, and organizations and individuals need to protect their devices from becoming part of a botnet by using up-to-date antivirus software, firewalls, and practicing good cybersecurity hygiene.

What Is A BotNet?

A botnet works by infecting multiple devices (often referred to as “zombies” or “bots”) with malicious software (malware) and then allowing a central controller, known as the botmaster, to remotely command and control these devices. Here’s a step-by-step breakdown of how a botnet typically operates:

1. Infection:

The process begins when a device is infected with malware that allows it to be controlled remotely. This malware can be spread through various methods:

• Phishing emails: Malicious links or attachments that, when clicked, install the malware.
• Exploiting software vulnerabilities: Malware can take advantage of unpatched security holes in operating systems, software, or applications.
• Malicious websites: Visiting a compromised website or one that hosts exploit kits can result in automatic malware downloads.
• Trojan horses: Software that pretends to be legitimate but secretly installs malware when executed.
• Social engineering: Convincing a user to download and install the malicious software themselves.

Once the malware is installed on the device, it connects back to the command-and-control (C&C) server controlled by the attacker.

2. Connection to the Command-and-Control (C&C) Server:

After infection, the bot establishes a connection to a central server (or a set of servers) controlled by the attacker. The C&C server sends commands to the infected devices, and the bots report back on their status.

• Centralized C&C: In a centralized botnet, all infected devices communicate with a single server controlled by the botmaster. The server sends commands and updates to the bots.
• Decentralized (P2P) C&C: Some advanced botnets use a peer-to-peer (P2P) architecture, where infected devices communicate directly with each other and distribute commands, making it harder to shut down the botnet.

3. Botnet Command Execution:

Once the bots are connected to the C&C server, the botmaster can issue commands that will be executed by all or selected infected devices. Some common commands include:

• DDoS (Distributed Denial-of-Service): Directing all infected bots to flood a target website or server with massive amounts of traffic, overwhelming it and causing it to go offline.
• Data theft: Commands to capture sensitive information, such as login credentials, financial data, or personal information.
• Spamming: Directing infected devices to send out large volumes of spam emails, often for the purpose of spreading malware or conducting phishing attacks.
• Cryptocurrency Mining: Instructing infected devices to perform resource-intensive mining operations for cryptocurrency like Bitcoin or Monero.
• Credential stuffing: Using the bots to automatically try stolen login credentials on various websites in an attempt to gain unauthorized access to accounts.

4. Scalability:

Botnets can consist of hundreds, thousands, or even millions of compromised devices, making them highly scalable and difficult to stop. The botmaster can issue commands to any number of infected devices at once.
The scale and reach of the botnet often depend on how many devices it has infected, as well as the geographical distribution of those devices.

5. Obfuscation and Persistence:

Botnets are designed to be stealthy and persistent. They often use several techniques to avoid detection and removal:

• Encryption: Communications between the bots and the C&C server are often encrypted to prevent detection by network monitoring tools.
• Self-replication: Some botnets can spread themselves further, infecting new devices automatically and adding them to the botnet.
• Anti-analysis techniques: Botnet malware might check whether it’s running in a virtual machine or being analyzed by antivirus software before activating itself.
• Periodic updates: The botnet malware can be updated remotely to improve its stealth or add new capabilities.

6. Monetization:

The botmaster typically uses the botnet to carry out illegal activities for financial gain.
Some common monetization strategies include:

• Renting out the botnet: Cybercriminals may rent out the botnet to others for malicious purposes, such as launching DDoS attacks, spamming, or stealing data.
• Selling stolen data: If the botnet is stealing sensitive information, it can be sold on the dark web.
• Cryptocurrency mining: The botmaster may use the infected devices’ processing power to mine cryptocurrencies, which can be highly profitable.
• Ransomware delivery: The botnet can be used to distribute ransomware, which locks the victim’s data and demands a ransom for its release.

7. Challenges in Detection and Mitigation:

Botnets are difficult to detect and neutralize because:

• Distributed nature: Botnets rely on a large number of devices spread across many different networks, making it hard to target them all at once.
• Fast-flux: Some botnets use dynamic DNS techniques like “fast-flux” to constantly change their C&C servers’ IP addresses, making it hard for security researchers and authorities to track them down.
• Encryption: Botnet traffic is often encrypted, making it difficult for network monitoring tools to identify malicious activity.
• Diverse infected devices: Botnets can infect a wide variety of devices, including computers, smartphones, and IoT devices (such as smart cameras or routers), many of which may not have robust security protections.

8. Botnet Disruption and Defense:

Efforts to dismantle or disrupt a botnet generally include:

• Identifying and shutting down C&C servers: Law enforcement and security organizations can take down or seize the botmaster’s C&C infrastructure, disrupting the botnet’s operations.
• Botnet takedown operations: Organizations like Google, Microsoft, and cybersecurity firms sometimes work together to disrupt botnets by pushing out updates to the infected devices or issuing “sinkhole” commands.
• Botnet detection tools: Security solutions that identify botnet traffic, use machine learning models to spot anomalies, or look for common indicators of botnet activity.

9. Preventing Botnet Infections:

To avoid becoming part of a botnet:

• Keep software updated: Regularly update your operating system, software, and devices to fix security vulnerabilities.
• Use antivirus software: Use reliable antivirus or anti-malware programs to detect and block malicious software.
• Avoid suspicious links and attachments: Be cautious when opening unsolicited emails or clicking on suspicious links.
• Implement network security: Use firewalls and intrusion detection systems to monitor network traffic for signs of botnet activity.
• Enable two-factor authentication (2FA): This adds an extra layer of protection to your accounts, making them harder to hijack even if your credentials are compromised.

A botnet operates by infecting many devices with malware and using them for malicious purposes, typically controlled by a botmaster. The botnet can be used for a variety of criminal activities, and its decentralized nature makes it a significant challenge for cybersecurity professionals to dismantle and stop.

Part 1: BotNets – What Are They and What Is Their Purpose?

What Are Botnets?

A botnet is a network of compromised computers or devices, known as “bots” or “zombies,” which are controlled remotely by an attacker, often referred to as a “botmaster” or “bot herder.” These botnets can be used to perform a variety of malicious activities, typically without the knowledge of the device owners.

Evolution of Botnets

1. Early Days:
   • IRC-Based Botnets (1990s): The earliest botnets used Internet Relay Chat (IRC) to command infected machines. These bots were often created for fun or minor pranks but set the stage for more serious threats.
   • Example: The “Sub 7” and “Back Orifice” trojans were among the first to create such networks.
2. 2000s – Rise of Complexity:
   • Peer-to-Peer (P2P) Networks: Botnets evolved to use P2P networks to avoid centralized control and improve resilience.
   • Example: The “Storm Worm” utilized a P2P architecture to distribute commands.
3. 2010s – Advanced Botnets:
   • Botnets as a Service: The commercialization of botnets turned them into a service for hire.
   • Example: The “Mirai” botnet, which primarily targeted IoT devices, became infamous for its scale and impact.
4. 2020s – Sophisticated and Distributed Attacks:
   • Targeted Attacks and Cryptojacking: Modern botnets often focus on specific targets or exploit devices for cryptojacking.
   • Example: “Emotet” and “TrickBot” are known for their sophisticated modularity and targeted attacks.

Common Uses of Botnets

1. Distributed Denial of Service (DDoS) Attacks:
   • Overwhelm a target server or network with traffic to make it inaccessible.
2. Spam and Phishing:
   • Distribute large volumes of spam emails or phishing attempts to harvest personal information.
3. Data Theft:
   • Steal sensitive information from compromised systems.
4. Cryptojacking:
   • Utilize infected devices to mine cryptocurrency without the user’s consent.
5. Click Fraud:
   • Automate clicks on online ads to generate fraudulent revenue.

Key Terminology

• Botmaster/Bot Herder: The individual who controls the botnet.

Part 2: A Basic Example of a Botnet

Overview

Let’s look at a simple Python script example to demonstrate the concept of a botnet. This example is for educational purposes only and should not be used for any malicious activities.

Basic Botnet Example in Python

# Example BotNet In Python:

import socket
import threading

# This is the bot (client) code.

def connect_to_server():
    server_ip = "127.0.0.1"  # IP of the command and control server (for demonstration)
    server_port = 12345      # Port of the command and control server

    s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    try:
        s.connect((server_ip, server_port))
        print("Connected to server")
        
        while True:
            command = s.recv(1024).decode('utf-8')
            if command == "shutdown":
                print("Shutting down...")
                break
            else:
                # Execute command
                print(f"Received command: {command}")
                # For security reasons, this part is left out in this example.
                # You could use os.system(command) to execute commands.
        
    except Exception as e:
        print(f"Error: {e}")
    finally:
        s.close()

def main():
    # Create multiple threads to simulate multiple bots
    for i in range(5):  # Simulating 5 bots
        t = threading.Thread(target=connect_to_server)
        t.start()

if __name__ == "__main__":
    main()

Explanation

1. Socket Setup:
   • The socket library is used to create a network connection. The bot connects to a predefined IP address and port number of the command and control (C2) server.
2. Connection Handling:
   • The connect_to_server() function establishes a connection to the C2 server and listens for commands.
3. Command Execution:
   • The bot waits for commands from the C2 server. If it receives a command (e.g., “shutdown”), it performs the action. In a real-world scenario, commands could be anything, including executing system commands or sending data.
4. Multithreading:
   • Multiple threads are created to simulate multiple bots connecting to the C2 server concurrently. Each thread represents an individual bot.
5. Error Handling:
   • Basic error handling is in place to catch and display any exceptions that occur during the connection or execution process.

Note

This example demonstrates a simplified version of a botnet client. In real-world scenarios, botnets are more complex and include additional features such as encryption, obfuscation, and advanced command structures. This script is provided for educational purposes to understand the basic principles of how botnets operate.

I collect a lot of data and data mining is just one of those things that I enjoy.
I build Web Crawlers and Web Scrapers often, but I really love tracking other
bots, some of which I’ve “known” for decades now.

With the ever expanding Facebook Empire, I’ve been catching a lot of the
hits from FacebookExternalHit,
[ facebookexternalhit/1.1 (+http://www.facebook.com/externalhit_uatext.php) ]
and while Facebook it’self is being overrun by nefarious bots and hacked accounts,
their problem is my solution.

The majority of the hits from FacebookExternalHit have preceded an attack, which tells me several things.
1: Facebook For Developers has given nefarious actors an edge on the Facebook user and I won’t go into detail on that, but I can make better informed security decisions based on what can be done from that side of the platform.

2: I can test my security software on both Facebook and my websites by simply posting a link to Facebook and this is really handy in my line of work. I get to see which Data Center the bot is coming from (GeoLocation), how many bots that particular Data Center has (Interesting Data There) and how fast the reaction time is, which helps determine the software being used and in which manner it’s being used.

3: Most Importantly, it gives me reasons to build new software.

So, I built this database for such purpose as to collect more data on the situation and there’s some interesting patterns developing. While it’s not exactly something I feel the urge to release, it’s worth sharing.

FBDC uses Php and MySQL, a pretty simple database and small file sizes (I like small files).
The User Input Form Works.. Ikr, a form that works??
It has a few things left to work out on the user input; I’m a big fan of getting my hands dirty,
so Updating the Data Center / BotInfo is being done via phpmyadmin until I build a better form.
Here’s a few screenshots:

 

 

 

 

Russian Hackers breached Microsoft to find out what Microsoft knows about them..

Maybe Microsoft should use Linux?

Original Article: TechCrunch

Wouldn’t you want to know what tech giants know about you?
That’s exactly what Russian government hackers want, too.

On Friday, Microsoft disclosed that the hacking group it calls Midnight Blizzard, also known as APT29 or Cozy Bear — and widely believed to be sponsored by the Russian government — hacked some corporate email accounts, including those of the company’s “senior leadership team and employees in our cybersecurity, legal, and other functions.”

Curiously, the hackers didn’t go after customer data or the traditional corporate information they may have normally gone after. They wanted to know more about themselves, or more specifically, they wanted to know what Microsoft knows about them, according to the company.

“The investigation indicates they were initially targeting email accounts for information related to Midnight Blizzard itself,” the company wrote in a blog post and SEC disclosure.

According to Microsoft, the hackers used a “password spray attack” — essentially brute forcing — against a legacy account, then used that account’s permissions “to access a very small percentage of Microsoft corporate email accounts.”

Microsoft did not disclose how many email accounts were breached, nor exactly what information the hackers accessed or stole.

Company spokespeople did not immediately respond to a request for comment.

Microsoft took advantage of news of this hack to talk about how they are going to move forward to make itself more secure.

“For Microsoft, this incident has highlighted the urgent need to move even faster. We will act immediately to apply our current security standards to Microsoft-owned legacy systems and internal business processes, even when these changes might cause disruption to existing business processes,” the company wrote. “This will likely cause some level of disruption while we adapt to this new reality, but this is a necessary step, and only the first of several we will be taking to embrace this philosophy.”

APT29, or Cozy Bear, is widely believed to be a Russian hacking group working responsible for a series of high-profile attacks, such as those against SolarWinds in 2019, the Democratic National Committee in 2015, and many more.

The Clown Show Must Go On!

SSH-Snake, a self-modifying worm that leverages SSH credentials.

Original Article : The Hacker News

A recently open-sourced network mapping tool called SSH-Snake has been repurposed by threat actors to conduct malicious activities.

“SSH-Snake is a self-modifying worm that leverages SSH credentials discovered on a compromised system to start spreading itself throughout the network,” Sysdig researcher Miguel Hernández said.

“The worm automatically searches through known credential locations and shell history files to determine its next move.”

SSH-Snake was first released on GitHub in early January 2024, and is described by its developer as a “powerful tool” to carry out automatic network traversal using SSH private keys discovered on systems.

In doing so, it creates a comprehensive map of a network and its dependencies, helping determine the extent to which a network can be compromised using SSH and SSH private keys starting from a particular host. It also supports resolution of domains which have multiple IPv4 addresses.

“It’s completely self-replicating and self-propagating – and completely fileless,” according to the project’s description. “In many ways, SSH-Snake is actually a worm: It replicates itself and spreads itself from one system to another as far as it can.”

Sysdig said the shell script not only facilitates lateral movement, but also provides additional stealth and flexibility than other typical SSH worms.

The cloud security company said it observed threat actors deploying SSH-Snake in real-world attacks to harvest credentials, the IP addresses of the targets, and the bash command history following the discovery of a command-and-control (C2) server hosting the data.

How Does It Work?

These attacks involve active exploitation of known security vulnerabilities in Apache ActiveMQ and Atlassian Confluence instances in order to gain initial access and deploy SSH-Snake.
“The usage of SSH keys is a recommended practice that SSH-Snake tries to take advantage of in order to spread,” Hernández said. “It is smarter and more reliable which will allow threat actors to reach farther into a network once they gain a foothold.”

When reached for comment, Joshua Rogers, the developer of SSH-Snake, told The Hacker News that the tool offers legitimate system owners a way to identify weaknesses in their infrastructure before attackers do, urging companies to use SSH-Snake to “discover the attack paths that exist – and fix them.”

“It seems to be commonly believed that cyber terrorism ‘just happens’ all of a sudden to systems, which solely requires a reactive approach to security,” Rogers said. “Instead, in my experience, systems should be designed and maintained with comprehensive security measures.”

“If a cyber terrorist is able to run SSH-Snake on your infrastructure and access thousands of servers, focus should be put on the people that are in charge of the infrastructure, with a goal of revitalizing the infrastructure such that the compromise of a single host can’t be replicated across thousands of others.”

Rogers also called attention to the “negligent operations” by companies that design and implement insecure infrastructure, which can be easily taken over by a simple shell script.

“If systems were designed and maintained in a sane manner and system owners/companies actually cared about security, the fallout from such a script being executed would be minimized – as well as if the actions taken by SSH-Snake were manually performed by an attacker,” Rogers added.

“Instead of reading privacy policies and performing data entry, security teams of companies worried about this type of script taking over their entire infrastructure should be performing total re-architecture of their systems by trained security specialists – not those that created the architecture in the first place.”

The disclosure comes as Aqua uncovered a new botnet campaign named Lucifer that exploits misconfigurations and existing flaws in Apache Hadoop and Apache Druid to corral them into a network for mining cryptocurrency and staging distributed denial-of-service (DDoS) attacks.

The hybrid cryptojacking malware was first documented by Palo Alto Networks Unit 42 in June 2020, calling attention to its ability to exploit known security flaws to compromise Windows endpoints.
As many as 3,000 distinct attacks aimed at the Apache big data stack have been detected over the past month, the cloud security firm said. This also comprises those that single out susceptible Apache Flink instances to deploy miners and rootkits.

“The attacker implements the attack by exploiting existing misconfigurations and vulnerabilities in those services,” security researcher Nitzan Yaakov said.

“Apache open-source solutions are widely used by many users and contributors. Attackers may view this extensive use as an opportunity to have inexhaustible resources for implementing their attacks on them.”

Hacker News:
Russian Hackers Have Infiltrated U.S. Household and Small Business Routers, FBI Warns
Original Article: MSN News

The FBI has recently thwarted a large-scale cyberattack orchestrated by Russian operatives, targeting hundreds of routers in home offices and small businesses, including those in the United States.

These compromised routers were used to form “botnets”, which were then employed in cyber operations worldwide.

The United States Department of Justice has attributed this cyberattack to the Russian GRU Military Unit 26165. Countermeasures undertaken by authorities ensured that the GRU operators were expelled from the routers and denied further access, ABC News reported.

The GRU deployed a specialized malware called “Moobot,” associated with a known criminal group, to seize control of susceptible home and small office routers, converting them into “botnets” — a network of remotely controlled systems.

The Justice Department, in an official statement, explained, “Non-GRU cybercriminals installed the Moobot malware on Ubiquiti Edge OS routers that still used publicly known default administrator passwords. GRU hackers then used the Moobot malware to install their own bespoke scripts and files that repurposed the botnet, turning it into a global cyber espionage platform.”

Utilizing this botnet, Russian hackers engaged in various illicit activities, including extensive “spearphishing” campaigns and credential harvesting campaigns against targets of intelligence interest to the Russian government, such as governmental, military, security and corporate entities in the United States and abroad.

Botnets pose a significant challenge for intelligence agencies, hindering their ability to detect foreign intrusions into their computer networks, Reuters notes.

In January 2024, the FBI executed a court-approved operation dubbed “Operation Dying Ember” to disrupt the hacking campaign. According to the Department of Justice, the FBI employed malware to copy and erase the malicious data from the routers, restoring full access to the owners while preventing further unauthorized access by GRU hackers.
