One of the largest blood donation organizations in the U.S. is dealing with major disruptions after a ransomware attack. The New York Blood Center (NYBC), which supplies blood to over 200 hospitals in the Northeast, confirmed the cyberattack on Wednesday. The incident has led to canceled appointments and longer processing times for donations.

According to the NYBC, suspicious activity was spotted on their systems on January 26. They’ve since taken steps to contain the threat, including shutting down certain systems. While the organization is working to restore operations, they haven’t set a specific timeline for when things will be back to normal.

This couldn’t come at a worse time. Just last week, the NYBC declared a blood emergency, citing a 30% drop in donations. Supplies of all blood types are running low, with some in critically short supply. The ransomware attack has only added to the challenges, forcing rescheduled blood drives and delayed services.

The blood center assured the public that they’re prioritizing the health of the community and staying in close contact with hospital partners. They’re also implementing workarounds to keep services running as best as possible.

For now, it’s unclear who’s behind the attack or whether any sensitive data was accessed. No ransom demands have been publicly confirmed. As the situation unfolds, the NYBC is urging donors to remain patient and supportive during this critical time.

If you’re able to donate, now’s the time to step up. Blood supplies are desperately needed, and every donation counts.
