Quid pro quo attack definition
A quid pro quo attack is a type of social engineering tactic where a cybercriminal promises a victim to deliver a helpful service or provide a benefit in exchange for sensitive information, such as login credentials or personal details. The phrase “quid pro quo” comes from Latin and means “something for something.”
Quid pro quo attack scheme
When launching a quid pro quo attack, the attacker offers the victim some benefit. It could be a service, such as removing malware and potential viruses from the victim's computer.
To receive this supposed benefit, the victim must first do what the attacker asks — for example, give them access to their computer or system or send them their login credentials. The main goal of the attack is to obtain sensitive data, like passwords, credit card details, or system access.
Some quid pro quo attacks might appear innocuous. Attackers may only ask for phone numbers or email addresses, but these can be used in future malicious campaigns, such as for phishing.
Common quid pro quo scenarios include phishing emails, fake tech support calls claiming to fix non-existent issues, or attackers posing as company representatives to gather personal information for future malicious campaigns.
Quid pro quo attack prevention
You can avoid most quid pro quo attacks by simply staying alert. Be cautious with unsolicited offers, like receiving unexpected emails or phone calls offering free services. Always verify requests for information before sharing personal details — check if a tech support call is legitimate or confirm an email request with the sender. The best protection is not engaging in any exchange unless you initiated the communication.
If you encounter suspicious activity, report it to your IT department immediately. For example, don’t provide login credentials or personal information to someone offering help with a computer issue you didn’t request.
