How to verify a colleague's identity in a messaging app: a security checklist for teams
We examine how to recognize social engineering in messaging apps, why urgent requests from colleagues should raise suspicion, and how to verify requests while maintaining a productive rhythm.
In the modern corporate environment, messaging apps have become the primary tool for real-time communication. However, this is exactly where risks hide: the habit of trusting a familiar name can lead to confidential data falling into the hands of bad actors. Social engineering exploits the human factor, forcing us to act on emotion and under the pressure of urgency.
When to be wary: signs of an unusual request
The first red flag is a change in tone. If a colleague who usually writes briefly and informally suddenly switches to dry, formal language or demands that you immediately send a file with passwords, this is a serious reason to pause. Other signs of a colleague's account being compromised include sudden persistence, strange abbreviations, uncharacteristic typos, or requests for actions that go beyond the employee's typical scope. Never send access credentials in response to a request that seems even slightly strange or suspicious.
Checklist: how to quickly verify a contact's identity
To protect your team, use this verification algorithm:
- Verify via a second channel. If in doubt, message the colleague in another corporate system or call them on an internal number.
- Clarify the context. Ask for a detail that only the two of you would know.
- Check the status. Ensure the account is not showing suspicious activity in other work groups.
- Request official confirmation. If you are asked for access to a resource, politely ask them to create a task in a tracker or send the request via corporate email.
These actions help to quickly verify a request from an employee in a chat without turning communication into paranoia.
How to politely clarify details and re-verify a request
Politely double-checking a contact's identity in work correspondence is a sign of professionalism, not distrust. Use simple phrases: "Hi! Let's log this request as a task so I don't miss anything in the current flow" or "Could you please tell me more about why this file is needed right now?" This approach allows you to maintain a professional rhythm without succumbing to manipulation.
How PING helps protect the team from social engineering
Team security is built on a culture of conscious communication. At PING, we focus on clear signals: a user should quickly understand what is happening in a conversation. PING tools help minimize noise and visually highlight important messages, which allows you to slow down and evaluate a request before making rash decisions. What to do if a colleague's account is compromised: an action plan for the team is a baseline every employee should know to stay calm in any situation.

Frequently asked questions
How do you avoid offending a colleague when asking them to verify their identity?
Security is a shared responsibility. Refer to company rules or internal guidelines: "We are currently following new security rules for all files, so I need task confirmation in the tracker." This sounds professional and does not offend anyone.
Which requests in a work chat should immediately raise suspicion?
Any requests for passwords, secret keys, access to financial accounts, or customer databases should be confirmed via an additional, secure communication channel.
Why do scammers use urgency in their messages so often?
Urgency suppresses critical thinking. When we are in a hurry, we stop verifying the sender. Slowing down is the primary defensive method that strips the attacker of their main advantage.
