Cybercriminals Exploit Layoff Anxiety With Fake HR Messages to Deploy Remcos Malware

Amid ongoing global layoffs, hiring freezes, and organizational restructuring, cybercriminals are exploiting employee fear and uncertainty to breach corporate networks.

Researchers at Seqrite Labs have uncovered a new phishing campaign that disguises the Remcos Remote Access Trojan (RAT) in

fake HR-related emails, designed to appear as official company communications.

The deceptive messages exploit the sensitive topic of job cuts, preying on the emotions of curious or anxious recipients.

The email, masquerading as a “Staff Performance Report for October 2025,” appears to come from a company’s HR department and briefly mentions “employees to be terminated.”

The combination of a professional tone and an alarming subject line is designed to capture immediate attention.

Attached to the message is a file named “staff record pdf.rar,” which seems like a harmless HR report in PDF format.

However, this attachment is actually a compressed RAR archive containing an NSIS (Nullsoft Scriptable Install System) compiled executable file named “staff record pdf.exe.”

This double-extension naming convention is a classic deception tactic. By appending “.pdf” to the file extension, attackers trick users into mistaking the file for a genuine document.

Once executed, the file silently installs the Remcos RAT, a powerful remote access tool that grants attackers complete control over the infected system.

Seqrite’s analysts warn that this approach reflects a growing trend: cybercriminals are increasingly leveraging real-world social issues, such as layoffs and internal HR processes, to manipulate emotions and circumvent rational caution.

As a result, employees under stress are more likely to overlook verification procedures and open infected attachments.

Technical Breakdown: Remcos Setup and Persistence

Further analysis by Seqrite Labs revealed that upon execution, the Remcos payload performs several silent installations to anchor itself within the system.

It drops configuration files into the user’s roaming directory at *C:UsersadminAppDataRoamingMicrosoftWindowsStart Menu* and copies its primary executable to C:ProgramDataRemcosremcos. Exe. 

To achieve persistence, Remcos adds an entry under the Windows Registry key HKCUSOFTWAREMicrosoftWindowsCurrentVersionRun, ensuring the malware launches automatically at system startup.

In addition to establishing persistence, the malware stores encrypted configuration data in another registry location, HKCUSoftwareRmc-<VictimID>, including the installed executable path, cracked Remcos license details, the victim machine ID, and the installation timestamp.

Once fully deployed, the RAT begins spawning multiple operational threads. Each thread supports specific functions, including keylogging, clipboard content tracking, screen capture, and system reconnaissance.

Shortly after initialization, the malware establishes an outbound connection to its command-and-control infrastructure hosted at IP address 196.251.116.219.

This communication confirms that the victim system is compromised and is ready to receive remote instructions. Seqrite detects this variant as a Trojan.Remcos.S38451216.

The campaign aligns with several MITRE ATT&CK framework techniques, including phishing attachments for delivery, masquerading via double extensions, NSIS-based obfuscation for evasion, registry key persistence, and data collection via keylogging and screenshots.

The combination of technical sophistication and emotional manipulation illustrates the attackers’ evolving approach to initial access.

Seqrite concludes that this campaign highlights a growing pattern where psychologically driven themes amplify the success rate of cyberattacks.

Organizations are therefore urged to strengthen their email security measures, implement attachment scanning, and train employees to evaluate HR- or policy-related communications critically.

Maintaining healthy suspicion, especially during periods of organizational change, remains a crucial defense against socially engineered malware attacks.
