No one is a stranger to the notion of security. We protect our homes and physical assets with locks and cameras and are vigilant when we encounter abnormal behavior. But for some reason, the data entrusted to us is not always given the same type of protection. Your data has become a prime target for cybercriminals which is manifested in the form of ransomware attacks. Attacks which are becoming increasingly prevalent.
Your data cannot be secured simply by restricting access. The whole point is to make data usable and available for people who need to use it, contribute to it, and manage it. The key to protecting content from ransomware is to understand how it infiltrates files. To be effective, all attackers need is access to files, and this can be achieved through rudimentary tactics. But with purposeful, automated analysis and alerting, ransomware attempts can be quickly detected, shut down, and remediated.
Ransomware and the damage done
Ransomware can be spread through phishing emails that contain malicious attachments. Attackers can also use social engineering to gain access to account credentials, and from there, it is easy to plant ransomware anywhere that account has access. The most common form of ransomware is crypto ransomware, which is a malware variant that encrypts files. Once your files are encrypted, a ransom message will appear onscreen demanding payment, typically in the form of Bitcoin or another untraceable cryptocurrency.
The reality is that attackers often successfully extort their victims. And these financial successes have led to a rise of ransomware attacks and variants. In 2013, destructive and lucrative ransomware variants were introduced, including Xorist, CryptorBit, and CryptoLocker. Some variants encrypt not just the files on the infected device, but also the contents of shared or networked drives.
