Breach Database / AerServ

Yes — AerServ was breached.

What happened

In April 2018, the ad management platform known as AerServ suffered a data breach. Acquired by InMobi earlier in the year, the AerServ breach impacted over 66k unique email addresses and also included contact information and passwords stored as salted SHA-512 hashes. The data was publicly posted to Twitter later in 2018 after which InMobi was notified and advised they were aware of the incident.

What data was exposed

What to do right now

  1. Change your password for this service now. And change it anywhere you reused the same password — attackers try leaked passwords on other sites within hours ("credential stuffing").
  2. Turn on two-factor authentication. Even a leaked password is useless against an account protected by a second factor. Prefer an authenticator app over SMS.
  3. Be alert for smishing and SIM-swap attempts. Treat unexpected texts and "carrier" calls with suspicion; add a PIN/port-freeze with your mobile carrier.
  4. Watch for targeted phishing mail. A leaked home address makes postal and doorstep scams more convincing.
  5. Expect convincing phishing emails. Attackers use breached details to write personalized emails. Be suspicious of any message referencing this service.
  6. Check your other accounts on Have I Been Pwned. Your email address may appear in other breaches you don't know about yet.
  7. Monitor the apps you use going forward. Clearly watches the breach record for the companies behind your apps and alerts you the moment one appears.
