In the digital era, our lives are increasingly intertwined with technology. From online banking to social media, we share and store vast amounts of personal and sensitive information on various platforms. While this technological advancement offers convenience, it also presents a lucrative opportunity for cybercriminals. These criminals are constantly on the lookout for valuable data they can exploit for financial gain or other malicious purposes. Understanding the types of data they target and how they steal it is crucial for protecting yourself and your assets.
This article delves into the various types of data that cybercriminals seek, the methods they use to obtain it, and the steps you can take to safeguard your information.
1. Why Cybercriminals Target Your Data
Cybercriminals are driven by various motives, most of which revolve around financial gain. The black market for stolen data is vast, with personal information, financial details, and business secrets fetching high prices on the dark web.
