ZGrab is a stateful application-layer scanner. ZGrab is written in Go and supports HTTP, HTTPS, SSH, Telnet, FTP, SMTP, POP3, IMAP, Modbus, BACNET, Siemens S7, and Tridium Fox. For example, ZGrab can perform a TLS connection and collect the root HTTP page of all hosts ZMap finds on TCP/443.
ZMap operates on GNU/Linux, Mac OS, and BSD. ZMap currently has fully implemented probe modules for TCP SYN scans, ICMP, DNS queries, UPnP, BACNET, and can send a large number of UDP probes. If you are looking to do more involved scans, e.g., banner grab or TLS handshake, take a look at ZGrab, ZMap's sister project that performs stateful application-layer handshakes.
ZGrab – Application Layer Scanner For ZMap
For what you're doing, Zmap or Masscan are probably the fastest way. Zmap's about as fast as masscan, but it has way more functionality. Another cool thing about Zmap is that you can pipe the results from the fast scanner into a slower, more intensive scanner, such as application layer with Zgrab. You should first scan with those tools and then use Nmap. It's way faster that way, and even better if you can do it just-in-time.
If you do not know the scan rate that your network can support, you may want to experiment with different scan rates or bandwidth limits to find the fastest rate that your network can support before you see decreased results.By default, ZMap will output the list of distinct IP addresses that responded successfully (e.g. with a SYN-ACK packet) similar to the following. There are several additional formats (e.g. JSON and Redis) for outputting results. Additional output fields can be specified and the results can be filtered using an output filter.

By default, ZMap will utilize a simple blacklist file containing reserved and unallocated addresses located at /etc/zmap/blacklist.conf. [more information]If you find yourself specifying certain settings, such as your maximum bandwidth or blacklist file every time you run ZMap, you can specify these in /etc/zmap/zmap.conf or use a custom configuration file.If you are attempting to troubleshoot scan related issues, there are several options to help debug. First, it is possible can perform a dry run scan in order to see the packets that would be sent over the network by adding the --dryrun flag. As well, it is possible to change the logging verbosity by setting the --verbosity=n flag.ZMap Copyright 2017 Regents of the University of MichiganSource: github.comShareezoicSiteSpeed(jQuery,String(/documentReady/).substring(1).slice(0,-1),String(/jQuery-document-ready/).substring(1).slice(0,-1),function($)$('head').append($('',id:'hide-sharre-count',type:'text/css',html:'.sharrre-container.no-counter .box .count display:none;'));$('#twitter').sharrre(share:twitter:true,template:'',enableHover:false,enableTracking:true,buttons:twitter:via:'the_yellow_fall',click:function(api,options)api.simulateClick();api.openPopup('twitter'););$('#facebook').sharrre(share:facebook:true,template:'',enableHover:false,enableTracking:true,buttons:layout:'box_count',click:function(api,options)api.simulateClick();api.openPopup('facebook'););$('#pinterest').sharrre(share:pinterest:true,template:'',enableHover:false,enableTracking:true,buttons:pinterest:description:'zmap: fast single packet network scanner',media:' -content/uploads/2018/01/zmap.png',click:function(api,options)api.simulateClick();api.openPopup('pinterest'););$('#linkedin').sharrre(share:linkedin:true,template:'',enableHover:false,enableTracking:true,buttons:linkedin:description:'zmap: fast single packet network scanner',media:' -content/uploads/2018/01/zmap.png',click:function(api,options)api.simulateClick();api.openPopup('linkedin'););var $_shareContainer=$(".sharrre-container"),$_header=$('#header'),$_postEntry=$('.entry'),$window=$(window),startSharePosition=$_shareContainer.offset(),contentBottom=$_postEntry.offset().top+$_postEntry.outerHeight(),topOfTemplate=$_header.offset().top,topSpacing=_setTopSpacing();shareScroll=function()var scrollTop=$window.scrollTop()+topOfTemplate,stopLocation=contentBottom-($_shareContainer.outerHeight()+topSpacing);$_shareContainer.css(position:'fixed');if(scrollTop>stopLocation)$_shareContainer.css(position:'relative');$_shareContainer.offset(top:contentBottom-$_shareContainer.outerHeight(),left:startSharePosition.left,);else if(scrollTop>=$_postEntry.offset().top-topSpacing)$_shareContainer.css(position:'fixed',top:'100px');$_shareContainer.offset(left:startSharePosition.left,);else if(scrollTop1024)topSpacing=distanceFromTop+$('.nav-wrap').outerHeight();elsetopSpacing=distanceFromTop;return topSpacing;$window.on('scroll',ezoicSiteSpeed(objOrFunction:_.throttle,object:_,function:String(/throttle/).substring(1).slice(0,-1),String(/documentReady/).substring(1).slice(0,-1),String(/jQuery-document-ready/).substring(1).slice(0,-1),function()if($window.width()>719)shareScroll();else$_shareContainer.css(top:'',left:'',position:''),50));$window.on('resize',ezoicSiteSpeed(objOrFunction:_.debounce,object:_,function:String(/debounce/).substring(1).slice(0,-1),String(/documentReady/).substring(1).slice(0,-1),String(/jQuery-document-ready/).substring(1).slice(0,-1),function()if($window.width()>719)shareMove();else$_shareContainer.css(top:'',left:'',position:''),50)););if(typeof ez_ad_units!='undefined')ez_ad_units.push([[970,90],'securityonline_info-banner-1','ezslot_9',105,'0','0']);__ez_fad_position('div-gpt-ad-securityonline_info-banner-1-0');Tags: ZMapNext story Attackers installed Coinhive code to mine Monroe on the official BlackBerry Moblie websitePrevious story Intel: CPUs affected by the vulnerabilities will be fully repaired by the end of JanuaryezoicSiteSpeed(jQuery,String(/documentReady/).substring(1).slice(0,-1),String(/jQuery-document-ready/).substring(1).slice(0,-1),function($)var _fireWhenCzrAppReady=function()czrapp.proRelPostsRendered=$.Deferred();var waypoint=new Waypoint(element:document.getElementById('pro-related-posts-wrapper'),handler:function(direction)if('pending'==czrapp.proRelPostsRendered.state())var $wrap=$('#pro-related-posts-wrapper');$wrap.addClass('loading');czrapp.doAjax(action:"ha_inject_pro_related",related_post_id:19880,pro_related_posts_opt:"id":"pro_related_posts_czr_module","title":"","enable":true,"col_number":3,"display_heading":true,"heading_text":"You may also like...","freescroll":false,"ajax_enabled":true,"post_number":10,"order_by":"rand","related_by":"categories",free_related_posts_opt:"1",layout_class:"col-2cl").done(function(r)if(r&&r.data&&r.data.html)if('pending'==czrapp.proRelPostsRendered.state())$.when($('#pro-related-posts-wrapper').append(r.data.html)).done(function()czrapp.proRelPostsRendered.resolve();$wrap.find('.czr-css-loader').css('opacity',0);ezoicSiteSpeed(objOrFunction:_.delay,object:_,function:String(/delay/).substring(1).slice(0,-1),String(/documentReady/).substring(1).slice(0,-1),String(/jQuery-document-ready/).substring(1).slice(0,-1),function()$wrap.removeClass('loading').addClass('loaded');,800);););,offset:'110%');;if(window.czrapp&&czrapp.methods&&czrapp.methods.ProHeaderSlid)_fireWhenCzrAppReady()elsedocument.addEventListener('czrapp-is-ready',_fireWhenCzrAppReady););Follow:Search
