Substack Data Leak? Here’s What Actually Happened

February 2026 ke start me Substack ne officially confirm kiya ek security incident jisme limited user data expose hua. Social media par rumors aur exaggeration chal rahi thi, isliye yeh article simple language me batata hai — kya hua, kya nahi hua, aur users ko realistically kya karna chahiye.


What Was Exposed (Aur Kya Safe Raha)

Substack ke according, breach ke through kuch account-level metadata access hua — jaise email addresses, phone numbers (agar linked the), aur internal identifiers.

Important part ye hai ki passwords, payment details, aur financial data compromise nahi hua . Matlab direct account takeover ya payment fraud ka risk low hai, lekin zero nahi.


How This Breach Actually Happened

Reports ke according, attacker ne traditional “hack” nahi kiya. Instead, system-level weakness ka use karke large-scale scraping kiya gaya. Is wajah se incident ka detection delayed hua.

Real Risk: Phishing & Social Engineering

Sabse bada practical risk yahan phishing ka hai. Jab attacker ke paas verified email ya phone hota hai, to fake Substack emails ya SMS kaafi convincing lag sakte hain.

  • Unexpected login alerts
  • Fake account suspension emails
  • Malicious links disguised as Substack updates

What Substack Did After Detection

Company ne vulnerability patch kar di, internal audit start ki, aur affected users ko directly notify karna shuru kiya. Yeh response timeline industry standards ke according reasonable maana ja raha hai.


What Users Should Do (Practical Checklist)

  • Enable two-factor authentication immediately
  • Password reuse avoid karein
  • Suspicious emails ya SMS ignore karein
  • Links par click karne se pehle sender verify karein
