Alert on malware protection

There is a reported increase in malicious activity by fraudsters in the telecommunication world. Complex malware, such as bot-nets may infect your systems and cause interruption or data-leak. Please keep your anti-virus updated and run frequent scans to prevent such infection. Click here for more details from CERT-in.


We would like to issue a general advisory to caution Indian telecom customers who are being arbitrarily targeted by calls fraudulently claiming the recipient customer as being a Prize/Lottery Winner.


In these types of phone frauds, the customer returns a missed call to a +92 or +375 country code and inadvertently reaches a fraudster pretending to be representative of airtel or another Indian mobile operator and informs the customer of having won some lottery/prize money. The fraudster then attempts to trick the customer into divulging sensitive personal information and to pay a commission to receive the winnings. Such commission is usually asked to be paid via an international DTH operator's recharge vouchers.


To protect all our mobile subscribers from such malicious activities which may result in substantial increase in your phone bill, airtel would like to advise the following:

  • Do not respond to any unexpected calls from a number with the +92 or +375 country code. Click here for more details
  • Do not respond to any suspicious missed calls from unknown numbers. In case of such suspicious calls, please report the same to us immediately.
  • Do not get lured into any financial transactions or divulge any personal information like IMEI, Bank Account number and other information to callers offering prize money or lottery winnings. Also do not respond to any instructions to dial an international number to get the prize money.
  • This luring may also be done through SMS messages offering prize money and seeking personal details on a specified email ID. Please do not respond to these.
  • Do not respond to any SMS/Email from unknown sources prompting you to call on a number or go to a site offering free download of content/movie clips/pictures.
