In a story reported by Brian Krebs we have yet another mainstream ransomware virus outbreak affecting a large medical facility.
It just goes to show how vulnerable both large and small organizations can be if they are unprepared for such an emergency. So far it sounds like only 1 of the 3 victims was fully prepared to deal with the outbreak (Ottawa), which means they probably has a good Backup and Disaster Recovery Plan (DR).
In the past few months there have been three notable outbreaks in hospitals:
- California Hospital ($17,000 Ransom)
- Ottawa Canada Hospital (Restored from Backup)
- Kentucky Hospital ($1,600 Ransom)
What is the Locky Ransomware Virus?
The Kentucky Methodist Hospital declared an “internal state of emergency” in order to deal with the infection caused by the “Locky Crypto-Ransomware Virus” (Symantec: Trojan.Cryptolocker.AF).
Locky “has been spreading quickly since it first appeared on Tuesday (February 16). The attackers behind Locky have pushed the malware aggressively, using massive spam campaigns and compromised websites.
One of the main routes of infection has been through spam email campaigns, many of which are disguised as invoices. Word documents containing a malicious macro are attached to these emails.”
“If this macro is allowed to run, it will install Locky onto the victim’s computer”
