snmp-smtp=smb扫描
小編覺得挺不錯(cuò)的,現(xiàn)在分享給大家,幫大家做個(gè)參考.
一、SNMP掃描
SNMP（簡(jiǎn)單網(wǎng)絡(luò)管理協(xié)議）明文
基于SNMP，進(jìn)行網(wǎng)絡(luò)設(shè)備監(jiān)控，如：交換機(jī)、防火墻、服務(wù)器，CPU等其系統(tǒng)內(nèi)部信息，基本都可以監(jiān)控到。 信息的金礦，經(jīng)常被管理員配置錯(cuò)誤 community：登錄證書，默認(rèn)值為public。容易被管理員遺忘修改其特征字符。兩個(gè)默認(rèn)的community strings，一個(gè)是public（可讀），另一個(gè)是private（可寫） 服務(wù)器：161端口，客戶端：162端口（UDP） MIB Tree：
SNMP Management Information Base（MIB） 樹形的網(wǎng)絡(luò)設(shè)備管理功能數(shù)據(jù)庫(kù) 在目標(biāo)主機(jī)上安裝SNMP服務(wù)，并查看服務(wù)的狀態(tài)、團(tuán)隊(duì)信息等。
控制面板——添加或刪除程序，出現(xiàn)下圖所示界面：
1、onesixtyone

如果沒有掃除查詢結(jié)果，有可能目標(biāo)主機(jī)已經(jīng)改變了它的默認(rèn)community，我們可以結(jié)合字典對(duì)其進(jìn)行掃描。 root@kali:~ /. /usr /usr/bin /usr/bin/onesixtyone /usr/share /usr/share/doc /usr/share/doc/onesixtyone /usr/share/doc/onesixtyone/README /usr/share/doc/onesixtyone/changelog.Debian.amd64.gz /usr/share/doc/onesixtyone/changelog.Debian.gz /usr/share/doc/onesixtyone/changelog.gz /usr/share/doc/onesixtyone/copyright /usr/share/doc/onesixtyone/dict.txt //默認(rèn)字典 /usr/share/man /usr/share/man/man1 /usr/share/man/man1/onesixtyone.1.gz root@kali:~ Logging to file my.log Scanning 1 hosts, 49 communities [ ] ,-./0123456789:;<=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_`abcdefghijklmnopqrstuvwxyz{|}~���������������������������������������
2、snmpwalk
能查出更多的信息，-c 指定community， -v指定使用的SNMP版本，2c版本使用比較廣泛，但可讀性不是很好。 root@kali:~ Created directory: /var/lib/snmp/mib_indexes iso.3.6.1.2.1.1.1.0 = STRING: "Hardware: x86 Family 6 Model 142 Stepping 9 AT/AT COMPATIBLE - Software: Windows Version 5.2 (Build 3790 Uniprocessor Free)" iso.3.6.1.2.1.1.2.0 = OID: iso.3.6.1.4.1.311.1.1.3.1.2 iso.3.6.1.2.1.1.3.0 = Timeticks: (176845) 0:29:28.45 iso.3.6.1.2.1.1.4.0 = "" iso.3.6.1.2.1.1.5.0 = STRING: "CHENGQIA-852040" iso.3.6.1.2.1.1.6.0 = "" iso.3.6.1.2.1.1.7.0 = INTEGER: 76 iso.3.6.1.2.1.2.1.0 = INTEGER: 2 iso.3.6.1.2.1.2.2.1.1.1 = INTEGER: 1 iso.3.6.1.2.1.2.2.1.1.327683 = INTEGER: 327683 iso.3.6.1.2.1.2.2.1.2.1 = Hex-STRING: 4D 53 20 54 43 50 20 4C 6F 6F 70 62 61 63 6B 20 69 6E 74 65 72 66 61 63 65 00 ...... iso.3.6.1.2.1.25.6.3.1.4.3 = INTEGER: 4 iso.3.6.1.2.1.25.6.3.1.5.1 = Hex-STRING: 07 E2 0B 19 11 32 2A 00 iso.3.6.1.2.1.25.6.3.1.5.2 = Hex-STRING: 07 E3 04 18 17 1A 16 00 iso.3.6.1.2.1.25.6.3.1.5.3 = Hex-STRING: 07 E2 0B 19 11 34 2E 00

3、snmp-check
相比snmpwalk，增強(qiáng)了可讀性

二、SMB掃描
SMB協(xié)議（Server Message Block）
微軟歷史上出現(xiàn)問題最多的協(xié)議； 實(shí)現(xiàn)復(fù)雜，默認(rèn)在Windows上是開放的，也是最常用的協(xié)議，用于實(shí)現(xiàn)文件的共享。 空會(huì)話未身份認(rèn)證訪問（SMB1）——Windows 2000/XP/Windows 2003
不用建立連接也可以獲取密碼，用戶名，組名，機(jī)器名，用戶、組ID 1、nmap

SMTP：Simple Mail Transfer Protocol，簡(jiǎn)單郵件傳輸協(xié)議。
