<p><strong>What is Ransomware?</strong><br />
Ransomware is a form of malicious software that encrypts files or locks systems, demanding payment (ransom) to restore access. It&rsquo;s one of the most damaging forms of cyberattacks globally.</p>

<hr />
<p><strong>Types of Ransomware</strong></p>

<ul>
	<li>
	<p><strong>Crypto Ransomware</strong>: Encrypts files and demands a decryption key in exchange for ransom.</p>
	</li>
	<li>
	<p><strong>Locker Ransomware</strong>: Locks users out of systems without encrypting files.</p>
	</li>
	<li>
	<p><strong>Double Extortion</strong>: Threatens to leak sensitive data if ransom isn&rsquo;t paid.</p>
	</li>
	<li>
	<p><strong>Ransomware-as-a-Service (RaaS)</strong>: Allows cybercriminals to rent ransomware tools.</p>
	</li>
</ul>

<hr />
<p><strong>Ransomware Delivery Lifecycle</strong></p>

<ol>
	<li>
	<p><strong>Reconnaissance</strong>: Identify weak entry points</p>
	</li>
	<li>

	</li>
	<li>
	<p><strong>Payload Delivery</strong>: Deploy ransomware</p>
	</li>
	<li>
	<p><strong>Encryption</strong>: Lock or steal data</p>
	</li>
	<li>
	<p><strong>Demand</strong>: Present ransom note</p>
	</li>
	<li>
	<p><strong>Optional Leak</strong>: Threaten data exposure</p>
	</li>
</ol>

<hr />
<p><strong>The Cost of Ransomware Attacks</strong></p>

<ul>
	<li>
	<p>Global ransomware damages expected to exceed <strong>$30 billion in 2025</strong></p>
	</li>
	<li>
	<p>Average ransom demand in 2024: <strong>$1.5 million</strong></p>
	</li>
	<li>
	<p>Recovery costs (downtime, lost data, IT services) are <strong>5&ndash;10x the ransom</strong></p>
	</li>
	<li>
	<p>Organizations that pay often get hit again</p>
	</li>
</ul>

<hr />
<p><strong>Should You Pay the Ransom?</strong></p>

<ul>
	<li>
	<p><strong>Experts advise against paying</strong>, as it encourages more attacks</p>
	</li>
	<li>
	<p>Paying doesn&rsquo;t guarantee data recovery</p>
	</li>
	<li>
	<p>Legal implications depending on the country (e.g., paying sanctioned groups)</p>
	</li>
	<li>
	<p>Better to focus on <strong>prevention, detection, and recovery</strong></p>
	</li>
</ul>
