Cybercriminals aren’t always on the outside—some are already inside your organization. Disguised as employees or contractors, fake IT workers can slip through security gaps, leading to costly breaches.
The impact? Massive financial loss and high-risk exposure. For example:
- $4.99 million: The average cost of an insider breach.
- 90% of global credit card transactions rely on mainframes—prime targets for cybercrime.
5 red flags you can’t ignore
- Credentials that don’t add up—Weak passwords and shared logins create an open door for cybercriminals.
- Suspicious payroll activity—Fake workers funnel money through ghost accounts.
- AI-enabled scams—Attackers use deepfake profiles and phishing to gain access.
- Insider threats—Disgruntled employees or contractors can do serious damage.
- Compliance gaps—Failing to meet GDPR and DORA regulations can be costly.
How to protect your mainframe
- Secure access—Prevent unauthorized logins with multi-factor authentication.
- Monitor activity—Track system access to detect suspicious behavior early.
- Leverage IAM—Control who gets access to critical systems with ease.
