🚨Substack Confirms Data Breach

Exposing Emails and Phone Numbers


Substack discovered an attacker accessed user information by exploiting a system weakness in October 2025.


The exposed data includes email addresses, phone numbers, and internal account metadata, though passwords, credit card numbers, and financial information were not affected.


The breach went undetected for up to four months, with Substack identifying evidence of unauthorized access on February 3, 2026.


The company has notified affected users by email and says it has fixed the underlying issue and launched a full investigation.


What You Should Do


  • Be cautious with unexpected emails or texts, especially those asking for personal information.
  • Watch for phishing attempts that use your email or phone number.
  • Review your Substack account for unusual activity and enable multifactor authentication if you haven’t already.

Today's Cool Tip

Lock Down Your Chats with WhatsApp’s Strict Account Settings


WhatsApp has introduced new Strict Account Settings designed to strengthen privacy and reduce unwanted contact. Here’s how the feature works, who gets it, and how to configure it for maximum control.


How many times have you been added to a random group chat or received a suspicious message from an unknown number? 


Messaging apps are essential for business and personal communication, but convenience often comes at the cost of privacy.


Here's a Cool Tip:  Set WhatsApp's Strict Account Settings.


WhatsApp’s latest privacy update, called Strict Account Settings, aims to rebalance that equation. 


These new controls give users stronger defenses against spam, unwanted group adds, and visibility exposure while preserving end-to-end encryption.


If you use WhatsApp for business coordination, family communication, or client outreach, this is a feature worth enabling.


Feature Explanation


Strict Account Settings adds an extra layer of privacy controls inside WhatsApp. 


It builds on existing settings such as Last Seen, Profile Photo, and Groups, but shifts your account toward a more restrictive posture by default.


In practical terms, it:

  • Limits who can add you to groups.
  • Reduces visibility of your profile details to unknown contacts.
  • Strengthens controls around messaging requests.
  • Helps prevent mass-add spam behaviors.


The feature is designed to provide stronger privacy protection while maintaining encrypted messaging.


Why it matters: 


  • Spam and phishing increasingly originate inside messaging platforms. Reducing unsolicited contact lowers social engineering risk for both home users and business professionals.


What You’ll Gain


With Strict Account Settings enabled, you can expect:

  • Fewer unwanted group chat invitations
  • Reduced exposure of your profile information
  • Lower risk of messaging-based scams
  • More control over who can reach you


Step-by-Step Instructions


Here's how to do it.


iOS


  1. Open WhatsApp.
  2. Tap Settings in the bottom-right corner.
  3. Select Privacy.
  4. Select Advanced.
  5. Locate the new Strict Account Settings option.
  6. Enable the toggle.

  6. Enable Strict Account Settings or enhanced restrictions.


If you do not see the feature yet, it may still be rolling out.


Please note that these settings can only be managed from your primary mobile device


You cannot enable or disable Strict Account Settings from WhatsApp Web or the Desktop app.


Pros and Cons


Pros


  • Stronger spam protection that reduces unsolicited group invites for professionals.
  • Better client privacy for consultants, educators, and business owners.
  • Low-friction activation with simple toggle-based setup.
  • Preserves encryption while improving exposure control.


Cons


  • May limit networking if strict filtering blocks legitimate outreach.
  • Rollout timing varies, so some users may not see it yet.
  • Requires periodic review if your communication needs change.


Feature Access


  • Strict Account Settings is currently rolling out globally across iOS, and Android. 
  • Availability may vary by version and region.
  • No subscription is required. WhatsApp remains free to use.
