5 Common Cyber Threat Actors and Their Motivations

In today’s digital landscape, cyber threats don’t just come from one direction. Organisations face risks from both inside and outside their networks – and understanding who’s behind the attacks can help you take proactive steps to protect your systems, data, and people.

At Optimising IT, we help businesses build smarter security strategies by identifying the key players behind today’s most common cyber threats. Here are five types of threat actors you should be aware of – and what drives their attacks.

1. Cybercriminals – Financial Gain

Who are they?

Organised crime groups or independent hackers focused on making money.

Typical tactics:

• Ransomware
• Phishing scams
• Data theft and resale
• Business Email Compromise (BEC)

Motivation:

Pure profit. These attackers aim for the lowest-risk, highest-reward opportunities, and SMEs are often seen as easier targets.

Example:

Ransomware groups like LockBit or Clop, which target organisations of all sizes with data-encrypting malware and demands for cryptocurrency payments.

2. Third-Party Vendors & Supply Chain Threats – Trust Gaps in Your Network

Who are they?

Attackers exploiting vulnerabilities in your suppliers, partners, or software vendors.

Typical tactics:

• Compromising managed service providers (MSPs)
• Infiltrating software updates (e.g. trojanised patches)
• Exploiting cloud or SaaS misconfigurations
• Lateral movement through connected systems

Motivation:

To gain access to a larger pool of victims, especially if a vendor supports many clients. These attacks often go unnoticed – until the damage is done.

Example:

The SolarWinds breach, where attackers compromised a trusted IT management platform to access thousands of customer environments.

3. Hacktivists – Hacking for a Cause

Who are they?

Ideologically motivated individuals or collectives.

Typical tactics:

• Website defacements
• DDoS attacks
• Public data leaks

Motivation:

To make a political or social statement. While hacktivists may not always be after your data or money, they can cause serious disruption and reputational damage.

Example:

Campaigns by groups like Anonymous targeting organisations they view as unethical or unjust.

4. Insiders – The Threat From Within

Who are they?

Employees, contractors, or trusted partners with authorised access.

Typical tactics:

• Credential misuse
• Data leaks
• Unauthorised changes or sabotage

Motivation:

Ranging from personal grievances or financial incentives to accidental negligence. Insider threats are among the hardest to detect – and most damaging.

Example:

A staff member copying sensitive files before leaving a company, or accidentally sharing confidential information via unsecured platforms.

5. Script Kiddies – Low Skill, High Disruption

Who are they?

Amateur hackers using off-the-shelf tools with minimal technical know-how.

Typical tactics:

• Website defacement
• Password brute-force attacks
• Scanning for open ports or known vulnerabilities

Motivation:

For bragging rights, curiosity, or boredom. Despite limited expertise, their attacks can still take systems offline or expose data – especially for underprotected businesses.

Example:

The TalkTalk breach involved teenage hackers who leveraged publicly available tools to access millions of customer records.
