What to do if a colleague's account is hacked: an action plan for the team

A familiar situation: an urgent message arrives in a work chat from a colleague asking you to grant access to a file or follow a link. We often act automatically, trusting the sender’s familiar name. Yet modern phishing is built on precisely this trust. Here’s how to spot the danger in time and protect your team’s data without turning communication into paranoia.

To avoid becoming a link in a data-leak chain, use this checklist before clicking any suspicious link:

• Sender: Does the profile definitely belong to your colleague? Check the number or ID if you have doubts.
• Context: Is the request expected? Had we discussed this file before?
• Format: Why was the link or file sent here instead of through the work system?
• Permissions: Why is access needed right now, and why so urgently?

Colleagues’ accounts can be hacked or impersonated. If a message looks familiar, that does not mean your actual teammate is behind the keyboard. Phishing often reveals itself through unusual wording, strange shortened links, or requests that violate internal processes. If a colleague suddenly pressures you to act urgently and demands an immediate response, treat it as a reason to be cautious.

If a colleague asks for access to a file in the chat, verify the sender’s identity. The best way is to call or write through another independent messenger. Ask a project-related question that only this person would know how to answer. If you have already clicked the link, close the tabs, revoke the granted access in the file settings, and notify the IT department immediately. Screenshots will help with the investigation.

Introduce a two-confirmation rule: grant any access rights only after verification through another communication channel. Limit document permissions to the minimum necessary and share experiences of suspicious incidents so everyone knows what a typical trick looks like. In PING, we emphasize a clear signal: users should quickly understand what is happening in a conversation. This makes communication transparent, with requests supported by context and any anomalies immediately standing out as deviations from the norm.

Returning from vacation often comes with an uneasy feeling: dozens of missed notifications and hundreds of messages. How can you summarize a chat discussion to restore the context without spending hours reading? AI tools can now quickly turn a jumble of words into a structured project map.

AI systems can produce a summary in just a few steps. You will learn which decisions were made, which tasks were assigned, and who is responsible for them. This is not a replacement for thoughtful work, but a way to get oriented in the context after a long break.

Work correspondence is a living process. Important agreements are often mixed with spontaneous ideas, detail clarifications, and information noise. Without proper documentation, finding the truth turns into a lengthy investigation.

To effectively reconstruct the discussion, do the following: select the period you were away, copy the relevant text, and give the AI a specific role. For example, ask it to act as a “project manager.” State the goal: extract decisions, a task list with deadlines, and open questions.

The main mistakes when working with AI are uploading excessively large volumes of text, mixing different topics, and blindly trusting the conclusions. An AI system may interpret irony or a polite refusal as agreement. Never publish a summary without checking it against the original: always verify that the responsible person confirmed the task in the chat.

Before uploading text to an AI system, remove all confidential information: passwords, financial data, customers’ personal details, or internal company documents. Always follow your organization’s security policies.

Once you understand the situation, write a brief update to your colleagues. For more on structuring these summaries, read how to document agreements after a chat discussion. Clear documentation helps ensure the next summary will not be necessary.

Using analysis is one response to overloaded channels. At PING, we focus on a clear signal: users should quickly understand what is happening in a conversation. When everyone sticks to the point, the need to search for a needle in a haystack disappears on its own, supporting a healthy communication rhythm.

Mesh Wi‑Fi or a standard router for your apartment — a question that arises when the internet is fast in one room, but video calls and streams keep dropping in another. Often, the problem isn't your ISP plan, but the coverage: the signal weakens due to walls, furniture, and appliances.

Check your speed in different areas of your apartment. If everything works fine near the router, but pages load slowly, video quality drops, or the connection cuts out in a distant room, your coverage zone is insufficient. Interruptions while moving around also indicate a weak signal: your device is struggling to hold the connection at the edge of the range.

First, rule out simple causes: reboot your router, check the speed via a wired cable, update the firmware, and make sure the network isn't overloaded with too many connected devices.

A standard router is a single access point. A mesh system consists of several nodes that create a unified network and distribute coverage across the apartment. Your device automatically connects to the optimal node — this is known as seamless roaming.

Mesh does not increase your internet speed. If the nodes are connected via Wi‑Fi, part of the bandwidth is used to exchange data between them. Therefore, the speed in a distant room might be lower than near the main node.

Place your router closer to the center of the apartment; do not hide it in a closet or put it on the floor. Keep it away from metal surfaces and sources of interference. Try a different radio channel and re-measure your speed. Sometimes this is all it takes.

Place the main node where the internet is already stable, and the additional one between it and the problematic room, but not in a "dead zone." Do not place nodes behind large furniture or directly against a wall. After installation, check the speed, latency, and connection stability in different rooms. If possible, connect the nodes with a cable: this usually reduces speed loss.

For a small apartment, a modern router is usually sufficient. Mesh is justified for complex layouts, thick walls, or when you need a stable connection in different ends of the home. Measure the issue and try adjusting the router's position first before buying new equipment. At PING, we focus on a clear signal: the user should quickly understand what is happening in a chat. A stable home network helps ensure such communication stays uninterrupted.
