Training Steps

A Suspicious Phone Call

It's a typical Monday morning at Nexlify Solutions, and Alice is settling into her office desk. As she organizes her tasks, her mobile phone rings, displaying 'Unknown' on the caller ID.
Urgent Request

Curious, Alice answers the call. The caller introduces himself as Bob from IT. 'Hello, Alice. We're rolling out a critical security update today. You'll receive an email with instructions to install it immediately. Please follow them promptly.' Alice thanks the caller and hangs up, feeling a sense of urgency to comply.
Checking the Email

After the call, Alice opens her email client to check for the promised message. Among her inbox, she notices an email from 'IT Support' with the subject line 'Urgent: Security Update Required.' The email stands out due to its urgent tone, and Alice recalls the phone call, believing it's the legitimate update she was told about.
Reading the Email

Alice opens the and reads the email. The email appears professional, and the attachment seems consistent with the phone call. Alice, trusting the source, decides to proceed.
Antivirus Warning

Alice clicks to download the attachment, and 'security_update.exe' appears in her file manager. A brief antivirus warning pops up, suggesting the file might be suspicious. Reassured by the phone call and email's urgency, Alice dismisses the warning, thinking it's a routine update from Nexlify Solutions' IT team.
The Ransomware Attack

As soon as Alice runs the file, her screen flickers, and a menacing message appears: 'All your files have been encrypted. To regain access, pay 1 BTC. Do not attempt to remove this software, or you will lose your files forever.' Alice's heart sinks as she realizes she's fallen victim to a ransomware attack. Her critical work files are now inaccessible, and she feels panic and regret.
Resisting the Ransom

Alice takes a moment to collect herself. She recalls a Nexlify Solutions training session advising against paying ransoms, as it doesn't guarantee file recovery and funds cybercriminals. Determined not to give in to Bob's demands, she decides to follow proper protocol to address the situation.
Disconnecting from the Network

To prevent the ransomware from spreading to other Nexlify Solutions systems, Alice immediately turns off her PC and disconnects it from the network. She knows ransomware can propagate across shared drives, potentially causing more damage. By isolating her device, she limits the attack's impact.
Recognizing the Fake Email Address

Still shaken, Alice uses her second PC and reopens the malicious email to understand what went wrong. She notices the sender's address, 'itsupport@nexlifysolution.com', is slightly off from the legitimate Nexlify Solutions domain, 'itsupport@nexlifysolutions.com'.
Internal Support System

Alice knows she must inform Nexlify Solutions' IT department promptly. She uses the web browser to open the company's internal IT support ticketing system and signs into her account.
