The pattern
Nine days inside.
Four terabytes staged for theft. Only noticed when the ransomware fired.
In February 2024, attackers logged into Change Healthcare with stolen credentials, through a remote-access portal with no multi-factor authentication. For nine days they moved through the network, mapped it, and staged roughly four terabytes of data. Discovery came on day nine, when the ransomware deployed. Pharmacies and providers across the country felt it for months.
That is the pattern, not the exception. Mandiant’s M-Trends 2026 incident data puts the median intrusion at 14 days before discovery, and 25 days when the warning comes from outside the organization. Healthcare sits near the top of the target list, and in many ransomware cases the victim first hears about the breach from the attacker.
None of these environments were unmonitored. The tools logged the logins, the movement, the transfers. What was missing was a team trained to recognize the shape of an intrusion while it was still forming. That recognition is what Adversant teaches.
