今天,clamAV 扫描了我的 AWS 实例并检测到每个实例上都有受感染的文件。由于以下几个原因,它看起来像是误报:
所有这些文件都是在 2021 年创建的(为什么现在才被发现?)
每个实例的 SSH 端口都受到 MFA + 密码 + VPN 的保护。
所有这些文件都在 Conda 环境中,并且只有 exe 文件被感染(我的 AWS 实例是 Ubuntu 操作系统)。
这可能是同样的问题这里?

答案1
根据 Virustotal 引擎的最新问题,我发现一些防病毒引擎将其检测为恶意软件。我能给出的最佳建议是暂停对这些文件的所有操作几天。并在一周后重复检查。然后,如果您看到更多 AV 引擎确认它已被感染,您可以采取相应的措施。您也可以向 Clamav 提交案例(以前从未这样做过)并要求进行更深入的调查。
如果只有少数不太知名的 AV 名称提出警告,那么您可以高度肯定地确认文件没有问题并恢复操作。
