The team in IDS have put together some key information on how to identify and protect yourself from ransomware.

What is ransomware?

Ransomware is malware (malicious software) that encrypts files or restricts system access and operations until a ransom is paid. The potential impacts of ransomware can be devastating, including financial and data loss, operational disruption and reputational damage to the University.

How can attackers gain access to our systems?

• Sending phishing emails and tricking recipients into clicking malicious links.
• Using stolen credentials or trying different passwords for different logins (credential stuffing).
• Attacking insecure software to find weaknesses. Particularly software which has not received the most recent security updates.
• Trojan software which appears legitimate at face value but hides malware inside.

What do attackers target once they’re inside our systems?

• Scanning for valuable data, extracting personal information and credentials.
• Accessing other areas inside breached systems.
• Encrypting files making them inaccessible to us and then demanding a ransom.

How can I protect myself and the University from Ransomware?

• Be cautious of phishing emails.
• Use strong, unique passwords.
• Keep software updated.
• Manage privileged access with IDS.

If you notice anything unusual, disconnect from the internet, contact the IDS Service Desk, and change your passwords from an uninfected computer.
