Lethal Lock 勒索软件将加密您的文件

在分析新的恶意软件样本时，我们发现了一种名为 Lethal Lock 的勒索软件变种。该勒索软件会加密文件并将其扩展名（“.LethalLock”）添加到文件名中。此外，Lethal Lock 还会生成勒索信（“SOLUTION_NOTE.txt”）并更改受害者的桌面壁纸。

例如，被 Lethal Lock 加密的文件会重命名如下：“1.jpg”变为“1.jpg.LethalLock”，“2.png”变为“2.png.LethalLock”，等等。赎金通知首先承认网络实体“LETHAL LOCK”破坏了服务器安全。它称加密过程非常复杂，并警告说，如果没有解密密钥，几乎不可能恢复文件。它威胁说，如果 72 小时内不支付赎金，数据将永久丢失，并会立即采取行动。

其中包括通过 Telegram (@lethallock) 联系客户支持以及转移 25 比特币以获取解密密钥的说明。

如何保护您的数据免遭勒索软件攻击？

保护您的数据免受勒索软件攻击需要采取多层次的安全措施。您可以实施以下几种策略：

定期备份数据：确保定期备份重要文件，并将其存储在无法从主网络或系统直接访问的安全位置。这样，如果您成为勒索软件攻击的受害者，您可以从备份中恢复文件，而无需支付赎金。

保持软件更新：确保系统上的所有软件（包括操作系统、防病毒程序和应用程序）都已安装最新的安全补丁。过时软件中的漏洞可能会被勒索软件攻击者利用。

使用防病毒和反恶意软件：在所有设备上安装信誉良好的防病毒和反恶意软件并保持更新。这些程序可以帮助检测和阻止勒索软件威胁，防止其造成危害。

启用电子邮件过滤：实施电子邮件过滤解决方案以拦截可疑电子邮件并防止其进入您的收件箱。这有助于降低成为传播勒索软件的网络钓鱼攻击受害者的风险。
