Understanding the Anatomy of a Cyber Attack

Understanding the Anatomy of a Cyber Attack

You’re probably familiar with what it means to suffer a cyber attack. And you might feel confident in your ability to prevent an attack against your organization. But how well do you understand the anatomy of a cyber attack? Do you know what tools attackers use to target organizations, infiltrate their networks, and later cover their tracks?

In this article, we’ll delve into what goes on behind the scenes in a cyber attack. We’ll also offer tips on ways to prevent and respond to malicious intruders. 

Step 1: Reconnaissance

When it comes to the anatomy of a cyber attack, the first step is usually reconnaissance.

Attackers will often research a target organization and gather as much information as possible. This includes network information, IP addresses, domain names, and the personal information of employees within the company, like the CFO and members of the IT team.

Next, attackers search for vulnerabilities in the network that will allow them to gain entry. This process often takes months of planning and involves a lot of trial and error.

Once the hackers are able to gain access to the network, they can begin the attack.

Step 2: Attack

Every cyber attack will look different, depending on the circumstances and type of attack.

After entering the network, hackers will often use a rainbow table or other tools in order to steal credentials from higher-level employees. This grants them administrator privileges and allows them to easily access the entire network.

At this point, attackers will generally try to steal sensitive information in order to encrypt it or sell it on the Internet. They may also infect the organization’s network with a virus or inflict other damage for financial gain.

Step 3: Expansion

After the initial attack, hackers will often utilize malicious programs to maintain their control of the network.

They might expand to multiple systems within the organization or utilize programs to maintain control of the network, even after being detected.

At this stage within the anatomy of a cyber attack, hackers can often continue to infiltrate the network without administrator privileges.

Step 4: Obfuscation

Sometimes, hackers will attempt to mask the origins of the attack in order to avoid becoming detected. By covering their tracks, attackers also make it more difficult to determine how the attack started and how much information has been compromised. For successful obfuscation, hackers will use a variety of tools, including:
  • Spoofing
  • Log cleaning
  • Zombied accounts
  • Trojan commands
Cybersecurity experts generally consider obfuscation to be the final stage in the anatomy of a cyber attack.

Cyber Attack Prevention

Now that you understand the anatomy of a cyber attack, what can you do to prevent one from happening?

Understanding the Motive

One of the first steps is understanding the motive behind these kinds of attacks.

The most common motive for conducting a cyber attack is financial gain. Hackers will often encrypt or steal data in exchange for a ransom. Sometimes, they even try to sell the data online.

Other motives include damaging an organization’s reputation, spreading fear through cyber terrorism, and distracting the authorities from other, more dangerous attacks.

Protecting Your Organization

Having a skilled team of cybersecurity experts is critical in order to prevent a cyber attack. They’ve spent years researching and studying the anatomy of a cyber attack, and they can help you develop a plan to prevent a cyber attack and minimize its effects.

To help protect your business, your cybersecurity efforts should include:

  • Regularly testing your systems and network for vulnerabilities
  • Installing firewall and antivirus software to protect your network from malware and other viruses
  • Adopting multi-factor authentication for all employee accounts
  • Implementing intrusion prevention technology that can detect reconnaissance attempts
  • Encrypting your organization’s data
  • Setting up alerts for outgoing data
  • Conducting regular hardware and software audits to monitor the strength of your IT systems
  • Training employees to educate them on how to prevent and respond to cyber attacks

Responding to a Cyber Attack

Even after following the security protocols listed above, your organization might still fall prey to a cyber attack. That’s why it’s important to have a response plan in place for your team to follow. Utilizing techniques like encryption will help minimize the damage from a cyber attack, since it will take the attackers longer to try and access sensitive information. Additionally, a comprehensive backup and recovery plan will help you maintain access to your data in case of theft or other forms of data loss. In addition to protecting your data from attackers, here are several steps you should take following the attack:
  • Trace the attack to determine which device was initially infected.
  • Establish how much information was compromised during the breach.
  • Contact any customers whose information may have been affected.
  • Perform a total security update to ensure that no other devices are infected.
  • Update your security policies to prevent a similar attack from taking place in the future.

Applying Modern Technologies for Better Cybersecurity

Cyber attacks are evolving every year, making them more difficult to prevent and overcome.

However, technology is also improving, making it easier for businesses to withstand these attacks.

Through Artificial Intelligence (AI) and Machine Learning, cybersecurity experts are able to analyze the anatomy of a cyber attack and predict common attack strategies. These technologies are also making it easier for businesses to automate threat detection and data recovery.

And AI isn’t the only field making strides. Blockchain technology can help organizations detect data breaches by tracking any changes made to the blockchain. Blockchain also makes it easier to distribute data across a network, thus simplifying the process of data recovery.

Understanding the Anatomy of a Cyber Attack Will Help You Provide Greater Protection for Your Organization.

It’s impossible to prevent every cyber attack that might come your way, but understanding hackers and their motives can better prepare you to respond to these attacks.

By examining the anatomy of a cyber attack, you can learn the most common entry points and secure them against attacks. You’ll also be more prepared to identify data breaches early, thus providing greater protection to your organization.
