致命锁勒索软件

在检查潜在恶意软件威胁时，网络安全研究人员发现了一种名为 Lethal Lock 的勒索软件变种。此威胁会加密文件，并在其原始文件名中添加“.LethalLock”作为新扩展名。此外，Lethal Lock 还会在受感染的设备上创建勒索信，作为名为“SOLUTION_NOTE.txt”的文本文件。该威胁还会修改受害者的桌面壁纸。

例如，威胁会将受影响数据的文件名“1.png”更改为“1.png.LethalLock”，“2.pdf”更改为“2.pdf.LethalLock”，等等。

致命锁勒索软件向受害者勒索巨额款项

勒索信首先承认，一个名为“LETHAL LOCK”的网络实体破坏了服务器安全。随后，信中详细介绍了文件的加密过程，称其非常复杂，如果没有解密密钥，几乎不可能逆转。信中对违抗勒索要求的行为发出了严厉警告，强调如果在 72 小时内不支付赎金，将面临永久性数据丢失的风险，并会立即产生后果。

提供了通过 Telegram (@lethallock) 联系客户支持并转移 25 比特币以换取解密密钥的说明。

建议受害者不要满足赎金要求，因为攻击者在付款后提供必要的解密工具，不太可能履行承诺。同时，必须立即从受感染的计算机中删除勒索软件，以减轻进一步的数据丢失，并防止可能传播到同一网络内的其他设备。

采取有效措施保护你的设备免受恶意软件侵害

实施强大的网络安全措施对于保护设备免受恶意软件威胁至关重要。以下是用户应遵循的一些基本做法：

• 安装和更新安全软件：利用信誉良好的反恶意软件并保持其更新以检测和删除恶意软件。
• 启用防火墙保护：在任何设备上激活防火墙以观察和控制网络流量，防止未经授权的访问并阻止恶意软件。
• 保持操作系统和软件更新：始终更新您的操作系统、应用程序和软件，以修补潜在的安全漏洞并防范恶意软件使用的已知漏洞。
• 点击链接和下载文件时请谨慎：请务必小心处理未经请求的电子邮件、可疑链接和来自未指定来源的附件，因为它们可能包含恶意软件。在点击链接或下载文件之前，请验证发件人的真实性。

通过遵循这些网络安全最佳实践，用户可以降低恶意软件感染的风险，并显著保护他们的设备和数据免受恶意威胁。
