Record High Ransomware Hit the U.S. Healthcare Entities

A new report discovered that cybercriminals are slamming healthcare with treacherous ransomware. The 2nd quarter of the year was plagued with ransomware, CryptoWall being the most common type of malware identified.

In the 2nd quarter of 2016, a research study by the Security Engineering Research Team Quarterly Threat Report reviewed various U.S. industries including healthcare, retail, finance, education and technology. The report concludes that healthcare organizations took an enormous 88 percent of all ransomware infections.
The SERT report for Q2 2016 has observed that there was a decrease of ransomware detections between January and February but grew substantially in the following the months of March, April and May.

After the incident that occurred at the Hollywood Presbyterian in California a substantial spike of ransomware attacks (11 percent) was seen.

The most common detected ransomware of the quarter is known as CryptoWall. It uses a military-grade encryption to lock its victim’s files then demands a ransom in return for the decryption keys.

Ransomware was first detected in 1989 and has been evolving since. According to the SERT report, cybercriminals are excited by the return on investment that ransomware offers.

Ransomware attacks in healthcare seem to have no signs of decline, especially when these institutions often pay the demanded ransom. The probability of continued attack is without question.
