nmap: smb enumeration

Enumeration, in the context of cybersecurity, refers to the process of discovering information about a target system or network. This can include identifying users, groups, shares, services, and other resources.

Therefore, SMB enumeration would likely involve using tools and techniques to gather information about SMB shares and resources on a target system. This information could then be used by an attacker to identify potential vulnerabilities or targets for further exploitation.

How add a Tenable Vulnerability Management (formerly Tenable.io) Scanner to Tenable Security Center

https://docs.tenable.com/security-center/6_2/Content/AddTenableioScanner.htm?Highlight=Add%20Tenable%20Scanner

 *Note: By default, Tenable Vulnerability Management selects the regional scanner that corresponds with the location of your Tenable Vulnerability Management user account. For example, if you run a scan from a user account located in the United States, Tenable Vulnerability Management selects the United States scanner. If you run a scan from a user account in Germany, Tenable Vulnerability Management selects the Germany scanner.

How to send a command line mail by mutt with a gmail account?

Mutt is an open-source, text-based email client used in command-line interfaces. Known for its simplicity, flexibility, and powerful features, it supports various email protocols like IMAP and POP3.

Sending emails is an indispensable requirement for an application developer or system administrator. After Google disabled the less secure mail setting, the scripts I used to send emails using Gmail accounts stopped working.

By activating the 2FA (Two-Factor Authentication) feature in your Gmail account and defining an App, you can still use your scripts to send emails by using the password you set for this app.

The steps you need to follow for this solution are outlined below.

Steps:

--

1. Enable MFA

2. Define App Password

3. Install Mutt

4. Example Config:

set from = "aliokan@gmail.com"
set realname = "KALE - Server"
#set imap_user = "aliokan@gmail.com"
#set imap_pass = "myverysecretpassword"

set smtp_url = "smtp://aliokan@smtp.gmail.com:587/"
set smtp_pass = "myverysecretpassword"
set folder = "imaps://imap.gmail.com:993"
set spoolfile = "+INBOX"
set ssl_starttls = yes
set ssl_force_tls = yes

## Opsiyonel: E-postaları yerel olarak saklamak için
#set header_cache = ~/.mutt/cache/headers
#set message_cachedir = ~/.mutt/cache/bodies
#set certificate_file = ~/.mutt/certificates 

Test:

# echo "Bu bir test mesajıdır." | mutt -s "Test Konusu" targetmail@gmail.com

Possible error message:

No authenticators available
Could not send the message.

Solution:

# yum -y install cyrus-sasl-plain
