勒索软件攻击和防御
勒索软件是一种恶意软件，它会阻止用户访问计算机系统，直到他们向攻击者支付赎金。勒索软件不断增加：2021 年，全球有 68.5% 的组织遭受勒索软件的攻击。
没有任何迹象表明勒索软件攻击会减缓。2022 年 4 月，能源公司 Oil India 遭到攻击，黑客要求以 750 万美元换回其 IT 系统的控制权。Oil 公司没有立即支付赎金，而是向当地和国际官员寻求援助——在此期间遭受了巨大的经济损失。
为什么企业需要防范勒索软件？
组织需要采取防护措施来让自己免受勒索软件的侵害，因为如果没有这些防护，网络犯罪分子就会劫持您的系统，使您的运营陷入停顿，直到您支付赎金或使用广泛的缓解策略来收回您的数据。
