Let’s start by looking into the problem, a high-value target for cybercriminals is businesses in the financial services industry. Attacks on this industry have acceler Everything you need to know about Malicious Bots ated recently thanks to increasingly advanced botnets and other bot attack techniques used by hostile hackers. Credit card fraud, account takeover (ATO) attacks, distributed denial of service (DDoS) attacks, and content scraping from websites that provide financial services are the four most popular uses for botnets among hackers. These attack strategies each have quite distinct effects on the organization they target.
Let us learn about Bot and Botnet
A bot is a little piece of software that executes web requests automatically for various purposes. Bots are employed to complete activities without the involvement of a human, including everything from scanning website content to testing credit card numbers that have been obtained fraudulently to offering customer service support. A “bot attack” is usually a fraudulent attacker; a bot can be utilized both beneficially and detrimentally.
A bot attack uses automated online requests to trick, deceive, or interfere with a website, application, API, or end user. Beginning as straightforward spamming operations, bot attacks have developed into sophisticated, global criminal organizations with independent economies and infrastructures.
What Is a Botnet?
A huge group of computers and internet-connected devices that have been infected with malware and are under the control of a single operator is called a botnet (derived from the word “robot network”). Attackers launch massive attacks using these hacked devices to sabotage services, steal passwords, and gain illegal access to vital systems. The attacker(s) can take over these devices’ activities and control them remotely thanks to the botnet command and control model. The quantity of infected computers in a botnet determines its power. Attackers may remotely manage botnets and download software upgrades from them, which they can then use to instantly change the behavior of the bots.
What Is a Botnet attack?
An extensive cyberattack known as a botnet is one that involves remote control of malware-infected machines. For a botnet controller, it transforms infected machines into “zombie bots.” Botnets offer a bigger hazard than typical malware that replicates itself on a single computer or system because they allow a threat actor to carry out a lot of operations concurrently. In contrast to self-replicating malware, botnet attacks are more like having a threat actor operating within the network.
They can be scaled up or altered on the fly to cause even more harm, making them more complex than other malware attack types. Malware distributed through a botnet frequently includes network communication capabilities that enable attackers to utilize the botnet to communicate with other threat actors over the extensive network of infected machines. Attackers can infect computers, spread malware, and add additional devices to their network by using botnets. A botnet attack may aim to disrupt operations or pave the way for a subsequent attack.
Bot Attacks vs a Botnet Attack
Attacks using botnets might be viewed as a particular variety of the more general “bot assault.” Cyberattacks known as “bot attacks” use automated online requests to harm a website, application, or device.
Initially just spamming, bot assaults have developed into increasingly sophisticated operations meant to trick or control users. The accessibility of open-source botkits, or tools for constructing bots, is one of the causes of this.
These botkits, which are frequently offered for free online or on the Dark Web, can be utilized to carry out undesirable operations like scraping a website, hijacking an account, abusing form submissions, and creating botnet attacks, including DDoS attacks.
Data Targeted by Attackers in a Bot Attack?
Bots are a tool used to launch attacks on APIs and web applications with the goal of stealing or changing sensitive data. Below are typical bot attack scenarios:
Web Content Scraping
Fake Search Engine Bots vs. Real Search Engine Bots
Web scraping bots scrape and copy information from other websites automatically. These search bot imposters can pass for innocent search engine crawlers while they scan information, but they steal content without the knowledge or consent of the website owner.
Contrarily, legitimate search engine bots employ user agent strings to identify themselves (e.g., robots.txt, googlebot). In order to improve search engine results for users, Google and Bing deploy bot crawlers to index content.
Types of Scraped Web Content
The broad category of scraped web material includes text, graphics, HTML/CSS code, metadata, and e-commerce information. This content is repurposed by the attacker for exploitative purposes:
- republishing pay-wall news stories or copyrighted television programs
- Syndicating blog posts to steal organic traffic and SEO value
- collecting information on inventory or product prices to obtain a competitive edge
- assembling contact details to market to other companies as sales targets
- stealing HTML code in a phishing operation to create a phoney brand website
Account Takeover (ATO)
Large dumps of user credentials are frequently made accessible as a result of data breaches and sold to threat actors on the dark web. Then, hackers utilize automated bots to quickly test usernames and passwords in the authentication procedures for user accounts on commercial websites (a technique known as credential stuffing attacks).
Threat actors take control of website accounts after discovering valid user credentials and lock out legitimate users. Attackers access those accounts to steal personally identifiable information (PII) and saved payment methods, which they then use to carry out a variety of fraud schemes, including opening new credit card accounts and using the stored payment information to make transactions.
Form Submission Abuse
Why Does a Botnet Attack Happen?
More botnet assaults are possible due to the increase in connected devices. IoT devices are after all widely used. Globally, there are more than 31 billion IoT devices in use, including smart home and business gadgets. Home appliances, lighting, door locks, cameras, thermostats, smart plugs, digital assistants, and other gadgets can all be controlled by consumer IoT devices. Critical infrastructure and the healthcare industry both have their own collections of connected devices. Any internet-connected gadget has the potential to be used by zombie bots. Preventing an attack on these is the first step in defending against one.
Any device that uses the internet is vulnerable, after all. Increased IoT security exposes a larger attack surface by enabling quick access to lots of devices.
IoT device configuration errors and inadequate security configuration protocols are factors in the rising prevalence of botnets. Another contributing cause is the rise in employee remote access to business networks using their own devices and home networks.
What Are the Most Common Types of Botnet Attacks?
1. Brute Force Attack
When an attacker doesn’t know the target password, they will decide to perform a brute force attack (s). This attack technique takes advantage of a repetitive, quick password guessing technique. Malware directly communicates with the impacted service during a brute force attack to receive real-time feedback on password attempts. Leaked credentials or personally-identifying information may also be used in a brute force attack to try passwords.
2. Distributed Denial of Service (DDoS) Attacks
An extremely frequent botnet attack is a DDoS attack. DDoS in this instance floods a service with web traffic in order to bring it down and halt service. In 2016, the Mirai botnet shut down Dyn, a provider of domain name services, in two stages, degrading performance and resulting in outages of important client websites including Twitter and Soundcloud in some areas.
3. Spam and Phishing
Phishing attacks by attackers use email spam to deceive employees into disclosing sensitive data or login credentials. Phishing is also used to expand the botnet by gaining access to other devices.
4. Device Bricking
Attackers launch bots to brick devices throughout the course of several phases. When a device becomes bricked, malware that deletes its contents often does so to erase evidence of a main attack. A brick device is one that has stopped functioning and is therefore worthless.
