In February 2024, a 'digital storm' swept through UnitedHealth Group (parent company of Change Healthcare). Ransomware attacks are like a heavy bomb, instantly exploding in the online world, mercilessly exposing the personal information of nearly 100 million people to risks, and the scope of their impact is astonishing.
The attacker cleverly used the leaked credentials to bypass the "security barrier" of multi factor authentication and successfully infiltrated the Citrix portal account. With the help of horizontal mobility technology, they stole and leaked massive amounts of data like "Night Ghosts", and finally deployed file encryption ransomware, causing the entire system to crash and panic.
This attack is like a huge storm triggered by a 'butterfly effect', not only causing more than 100 applications under Change Healthcare to fall into difficulties, but also affecting many key areas such as clinical, dental, medical records, patient interaction, pharmacy, and payment services like dominoes. Thousands of pharmacies and medical service providers have been "recruited" one after another, and their businesses have suffered varying degrees of impact and interference.
In the era of surging digital waves, enterprises and individuals are like lonely boats sailing in the ocean of information, constantly facing the surging waves of network security. Among them, the precise grasp of default safety concepts is as crucial as ing a navigation compass. After all, data security is like air, closely intertwined and intertwined with each of our lives.
We should become the "security guardians" of the digital age, continuously learn about data security knowledge, hone our own security awareness, integrate security concepts into every click and data interaction, and work together to build a secure, harmonious, and stable network environment, guarding our digital home.
