Part 9/15:

Asia's recent ransomware incident involved a group that infiltrated a company's network, encrypted essential data, and demanded ransom payments. While the victim initially claimed no operational impact, such attacks can cause extensive delays, financial losses, and reputational damage.

Methods of Infection

Email remains a primary vector for ransomware delivery. For instance, malicious attachments or links in phishing emails—such as fake promotional offers (e.g., "free diamonds" in mobile games)—often deploy malware that propagates across networks. Once infected, systems display ransom notes, threatening to delete data unless a ransom is paid, often in cryptocurrencies like Bitcoin.
