Massive Cyber Attack and What You Need to Know
On Friday, May 12, 2017, the world was alarmed to discover that Cyber Crime had achieved a new record. In a widespread ransomware attack that hit organizations in more than 100 countries within the span of 48 hours, the operators of malware known as WannaCry/WanaCrypt0r 2.0 are believed to have caused the biggest attack of its kind ever recorded.
What is WannaCry?
WannaCry, WanaCrypt, or Wcry for short, is ransomware that works like other malware of its type, with a few intricacies that highlight the sophistication of its operators.
Malware spreads like a worm, crawling from one computer to all other devices connected to it. This particular malware comes with an encryption package attached to it which automatically downloads itself locking up all data and demands a ransom. WannaCry deletes all copies, disables Windows startup recovery, and clears the Windows Server Backup history to prevent victims from restoring their files without paying the ransom. All it takes is one computer to be infected to shut down and an entire network within your organization.
Perhaps more than anything else, this ransomware onslaught is a resounding reminder of security basics, especially when it comes to Microsoft product patching. Those who applied critical Microsoft Windows patches released in March were protected against this attack.
In addressing whether ransomware attacks are generally considered reportable breaches, “Under HIPAA, a breach is defined as the acquisition, access, use or disclosure of PHI in a manner not permitted under the HIPAA Privacy Rule which compromises the security or privacy of the PHI”. In a significant statement that aims to clarify reporting requirements, the guidance also points out: “When electronic PHI is encrypted as the result of a ransomware attack, a breach has occurred because the ePHI encrypted by the ransomware was acquired by unauthorized individuals [who] have taken possession or control of the information, and thus is a ‘disclosure’ not permitted under the HIPAA Privacy Rule”.
