I hope this question is on-topic here. I am completely puzzled at this. On 26-Feb-2020 at 4.24 PM IST an unknown SMS has been sent from my Redmi 7A Android Phone without my consent to a completely unknown number.
See the attached screenshot for the message contents (it starts with
ACTA and then contains some encoded data). It's all either encrypted or garbage. I have no clue what this is and I can not infer anything from this.
All apps before installation are scanned by built in security check. I have run security scan on my phone and nothing suspicious found except need to update MIUI. No app was installed on that day and I do not download any unknown apk's from unknown sites. All apps have always been installed from Google Play Store.
The number does not exist in my contact list and has never ever been dialed from or any call received on this phone. Could someone explain this? Any clarification on what this could have been would be great to know.
Truecaller site reports that number as a spam number from India.
