Overview

Have you watched Netflix's Black Mirror? It's an anthology series where each episode tells a standalone story, often exploring the darker aspects of our nature intertwined with technological innovations.

The first episode, 'The National Anthem,' deals with a shocking scenario where a Prime Minister faces a dilemma after he's blackmailed when Princess Susannah, heir to the royal family, is kidnapped. Undeniably, when a nation's leader is compromised, the consequences can be severe and far-reaching!

While this was a national threat, there are various kinds of security threats that take place in a digital space. One of them is Advanced Persistent Threats (APTs), sophisticated cyber-attacks backed by criminal organizations. These attacks aim to gain an unauthorized and persistent presence within a network, posing significant risks to organizations and governments.

While the subject is sensitive, it's crucial to raise awareness about APTs and their potential impact on security and privacy. By understanding these threats, we can better prepare and protect ourselves from their consequences.

That’s why this article will outline everything about Advanced Persistent Threats – its definition, types and examples. Dive in!

What is your worst nightmare?

If you are a cybersecurity professional, it would definitely be a cyber-attack on your organization, right? After all, nowadays, attackers have become more advanced than organizations with their meticulous planning and execution of cyber-attacks!

Coming to the theme of this article, as the name suggests, Advanced Persistent Threats are sophisticated, multi-layered attacks that are often executed over an extended period, with the sole purpose of stealing valuable information from targeted organizations.

As per reports by PurpleSec, 34% of companies have suffered reputation damage because of such attacks. Even more alarming, 68% of companies have experienced targeted network attacks and have suffered subsequent data loss as a result.

These numbers highlight the sensitivity of these advanced attacks. You see, they are not mere one-off attacks but rather calculated ones. Ignoring or underestimating them can lead to some irreparable damage, be it financially or in terms of reputation.

We’ll try to understand them closely by exploring their types and examples. However, before that, let’s find out what Advanced Persistent Threats are.
 

What Is An Advanced Persistent Threat?


An Advanced Persistent Threat (APT) is a sophisticated cyber-attack carried out by highly skilled hackers, usually targeting prominent organizations. While APTs are often sponsored by criminal groups, they are not ‘hit and run’ attacks, you see. They can remain undetected within the victim's network for a long time, sometimes months or even years.

Their mission? The primary goal of an APT attack is to gain unauthorized access to a network and maintain a persistent presence, allowing the attackers to collect valuable data or compromise critical systems. These attacks pose significant risks to organizations and governments, potentially leading to substantial financial losses, damage to reputation and theft of sensitive information.
 
Now that we understand what an Advanced Persistent Threat is, let’s understand its types.
 

Types Of Advanced Persistent Threats


Advanced Persistent Threats (APTs) come in various forms, each with their unique approach and consequences. Here are some common types of APTs that organizations should be aware of :
 
  • Account Take Over

    In this type of attack, cybercriminals gain unauthorized access to an individual's or organization's account, such as email, social media or banking accounts. Once inside, they can steal sensitive information, initiate fraudulent transactions or spread malware.

  • Ransomware

    This is a form of malware that encrypts the victim's data, rendering it inaccessible until a ransom is paid. Ransomware attacks can cripple an organization's operations and lead to significant financial losses.

  • Data Breach

    APTs may infiltrate a network with the sole purpose of stealing sensitive data, such as customer information, trade secrets or intellectual property. Data breaches can have severe consequences, including regulatory fines, legal liabilities and loss of customer trust.

  • Social Engineering

    Social engineering involves manipulating or deceiving individuals into revealing sensitive information or performing actions that compromise security. APTs may use tactics like phishing emails, pretexting or baiting to gain a foothold within an organization.

  • Business Email Compromise

    In this scam, cybercriminals impersonate executives or trusted parties to trick employees into transferring funds or revealing sensitive information. This can result in substantial financial losses and damage to an organization's reputation. Next time you find a strange email from your boss, beware!


While the types of APTs may sound intimidating, being aware of such tactics is the first step in defending against them. By implementing robust cybersecurity measures, providing employee training and staying vigilant, organizations can reduce their risk of falling victim to these persistent threats.

On that note, let’s go to the next segment of this article – examples of APT that will help us understand it more closely.
   

Examples Of Advanced Persistent Threats


Here are some real-world examples of APTs that illustrate their complexity and impact:
 
  • Hafnium

    Discovered by Microsoft, this Chinese state-sponsored APT group exploited vulnerabilities in Microsoft Exchange Server to gain access to email accounts and steal sensitive data. Hafnium has targeted various industries and sectors, including defense, healthcare and education.

  • Stuxnet

    A highly sophisticated worm designed to target and disrupt Iran's nuclear program, it was delivered via an infected USB device. Stuxnet inflicted damage on centrifuges used for uranium enrichment by attacking the industrial control systems (SCADA).

  • GhostNet

    Based in China, this APT used spear-phishing emails with malware to compromise computers in over 100 countries. The group focused on gaining access to government ministries and embassy networks, turning compromised machines into surveillance devices by activating their cameras and microphones.


These examples highlight the global reach and the potential consequences of APTs. They serve as a reminder about the importance of robust cybersecurity measures and the need for organizations to stay vigilant against these advanced and persistent threats. On that aspiring note, let’s have some final words!
 

Final Words


“The National Anthem" episode of Black Mirror serves as a stark reminder of the far-reaching consequences of an APT attack. When critical systems and individuals are compromised, the ripple effects can be devastating. To mitigate these risks, organizations must stay vigilant, implement multi-layered security measures and foster a culture of cybersecurity awareness.

As Robert Mueller wisely stated, "There are only two types of companies: those that have been hacked and those that will be."

Hope this explainer on Advanced Persistent Threats helps you battle such cyber threats!
