If no attack (payload) is configured, it will return 0.0.0. Once created, the DNS beacon listener will act as a DNS server, waiting for requests. Since Cobalt Strike Beacon is not saved on the filesystem, whether a device is infected cannot be confirmed just by looking for the file itself.

This will download a payload (Cobalt Strike Beacon), which will be executed within the memory.

Your Cobalt Strike team server system must be authoritative for this domain as well. Cobalt Strike is delivered via a decoy MS Word document embedding a downloader. This stager is only used with Cobalt Strike features that require an explicit stager. Can be IPv4 ( 1.2.3.4), IPv6 ( ), or domains ( abcdef.tld) DNS Host (Stager) Configures the DNS Beacon's TXT record stager.

Create NS records that point to the FQDN of the Cobalt Strike Team serverĭNS Hosts List of hosts, separated by a coma.

Create an A record for the Cobalt strike server.

You'll need to publish specific DNS entries: There is no HTTP communication mode in this payload. In Cobalt Strike 4.0 and later, the DNS Beacon is a DNS-only payload. b5igmaTuTmfvK/TJEgK5ZaPt95GBqVSo1JnWFtgds2yUyoDjGxGFmts+ ZAESfWt9MG0kdx1jm0U40uloy1vGYqTpVFTiq5mmHGuO5oo7pOUQMlIE mxX6o/7guxr9p1m/Q33rOmVVcrCmh3tJn34d4Q7cwCUsQ/6zlj4pYfeC ZfYcqThW圎f6aDW+JWaspv2EhpxLANYaD2DhvZ63rzwcew=

The DNS response will also tell the Beacon how to download tasks from your team server. The DNS response tells Beacon to go to sleep or to connect to you to download tasks. These DNS requests are lookups against domains that your Cobalt Strike team server is authoritative for.

Finally we create a thread in the remote process which calls LoadLibrary with the dll path as a argument.This payload uses DNS requests to beacon back to you.

From here, a page of memory is allocated in the remote process writing the full dll path into the newly allocated buffer. Then we get the address of LoadLibrary in memory, via GetProcAddress. This module works by opening a handle to the process we're going to inject into.

We'll start with the simpler of the two modules, dllload. There are two modules in particular i'd like to take a look at: dllinject Inject a Reflective DLL into a processĭllload Load DLL into a process with LoadLibrary() DLL Load It has become possible, with the recent addition of beacon object files, to implement a custom version of a pre-existing module. As well as implementing a wide array of post exploitation modules which can allow a red teamer to traverse around while remaining relatively OPSEC safe. It can be extremely powerful allowing with key features such as malleable C2 profiles, essentially making traffic look more legitimate when going across a network (i.e.
