Psychological Attack Scenario
When a hacker enters the correct password for your email or marketplace account, the security system triggers a second factor and sends an SMS. Immediately afterward, scammers often call pretending to be security or carrier support, claiming your account is under attack and demanding you read out the digits to cancel the operation.
Immediate Actions When Receiving an Unfamiliar Code
- decline incoming calls from any unknown numbers and under no circumstances read out the digits
- open the official app of the service yourself and quickly change your main password to a new one
- terminate all external active sessions in the account security settings
- set up two-factor authentication via a mobile authenticator app instead of insecure SMS
