Sophos, a global leader in next-generation cybersecurity, has published an article, “The Top 10 Ways Ransomware Operators Ramp Up the Pressure to Pay,” detailing how ransomware attackers are implementing a wide range of ruthless pressure tactics to persuade victims to pay the ransom. The article is based on evidence and insight from Sophos’ Rapid Response team of 24/7 incident responders who help organizations under active cyberattack. It highlights the shift in ransomware pressure techniques from solely encrypting data to including other pain points, such as harassing employees.
“Since organizations have become better at backing up their data and restoring encrypted files from backups, attackers are supplementing their ransom demands with additional extortion measures that increase the pressure to pay,” said Peter Mackenzie, director, Incident Response at Sophos. “For example, the Sophos Rapid Response team has seen cases where attackers email or phone a victim’s employees, calling them by their name and sharing personal details they’ve stolen – such as any disciplinary actions or passport information – with the aim of scaring them into demanding their employer pays the ransom. This kind of behavior shows how ransomware has shifted from a purely technical attack targeting systems and data into one that also targets people.”

How Attackers Ramp up the Pressure to Pay
Below are the top 10 ways attackers are increasing pressure on their ransomware victims to get them to pay the ransom:
- Stealing data and threatening to publish or auction it online
- Emailing and calling employees, including senior executives, threatening to reveal their personal information
- Notifying or threatening to notify business partners, customers, the media, and more of the data breach and exfiltration
- Silencing victims by warning them not to contact the authorities
- Recruiting insiders to help them breach networks
- Resetting passwords
- Phishing attacks targeting victim email accounts
- Deleting online backups and shadow volume copies
- Printing physical copies of the ransom note on all connected devices, including point of sale terminals
- Launching distributed denial-of-service attacks against the target’s website
The article explains each tactic in more detail, with examples of ransomware groups that have deployed that tactic. The article also includes advice on what defenders can do to protect their organization and employees from attacker behaviors and cyberthreats in general.
