Medical Centers impacted by ransomware around the U.S.
Medical Centers around the United States are becoming victims on ransomware. Now, during a time of COVID it’s causing more hardship than ever before. We’ve selected three briefs to share with you about the results and difficulties these circumstances have created for medical facilities.
Greater Baltimore Medical Center Hit by Ransomware Attack
BY MIKE LENNON
The Greater Baltimore Medical Center in Towson, Maryland was hit by a ransomware attack that impacted computer systems and medical procedures, the healthcare provider said Sunday. In late October, the U.S. government warned hospitals and healthcare providers of an “increased and imminent” ransomware threat. The alert warned that threat actors are targeting the healthcare sector with the TrickBot malware in attacks that often lead to ransomware infections, data theft and disruption of healthcare services.
The ransomware attack is the latest of many that have impacted healthcare providers over recent months. In September, a ransomware attack forced the shutdown of more than 250 locations operated by Universal Health Services (UHS). Also in September, an attack shutdown IT systems at a hospital in Duesseldorf, Germany, resulting in the death of a woman after she had to be taken to another city for urgent treatment.
TrickBot has been updated with functionality that allows it to scan the UEFI/BIOS firmwareof targeted system for vulnerabilities, security researchers recently discovered. READ MORE…
UHS Shuts Down Systems in U.S. Hospitals Following Cyberattack
BY IONUT ARGHIRE
In the end of September, 2020, Universal Health Services (UHS) shut down IT networks at multiple hospitals in the United States, after being hit with a cyberattack. A Fortune 500 company operating more than 400 facilities in the United States, Puerto Rico, and the United Kingdom, the healthcare services provider has approximately 90,000 employees and claimed an annual revenue of $11.4 billion for 2019. While many said that patient care wasn’t critically affected, others detailed difficulties in receiving lab results or performing other types of investigations in a timely manner. There was also one unconfirmed report of patients dying due to such delays. Furthermore, Bleeping Computer and TechCrunch report that information from people with knowledge of the incident leads to the conclusion that the Ryuk ransomware was used. READ MORE HERE…
As Hospitals Cope With a COVID-19 Surge, Cyber Threats Loom
BY ASSOCIATED PRESS
The (University of Vermont Medical Center) Vermont hospital had fallen prey to a cyberattack, becoming one of the most recent and visible examples of a wave of digital assaults taking U.S. health care providers hostage as COVID-19 cases surge nationwide.
The same day as UVM’s attack, the FBI and two federal agencies warned cybercriminals were ramping up efforts to steal data and disrupt services across the health care sector.
By targeting providers with attacks that scramble and lock up data until victims pay a ransom, hackers can demand thousands or millions of dollars and wreak havoc until they’re paid.
Ransomware is also partly to blame for some of the nearly 700 private health information breaches, affecting about 46.6 million people and currently being investigated by the federal government. In the hands of a criminal, a single patient record — rich with details about a person’s finances, insurance and medical history — can sell for upward of $1,000 on the black market, experts say.

A True Tale of Two Ransomware Attacks
Read a true tale about two different schools and how they each recovered from a ransomware attack. As you read, you’ll learn how an effective backup plan and a well-thought-out business continuity strategy is a critical part of your cyber security efforts. The similarities between the schools is that both ransomware attacks were thought to be started by the click of a phishing emails. The difference is in their disaster recovery plans.
RANSOMWARE PREVENTION
A TALE OF TWO SCHOOLS
Imagine a world where ransomware didn’t exist. Now, snap back to reality and read a tale about two different schools and how they each recovered from a ransomware attack. As you read, you’ll learn how an effective backup plan and a well-thought-out business continuity strategy is a critical part of your cyber security efforts. The similarities between the schools is that both ransomware attacks were thought to be started by the click of a phishing email. The difference is in their disaster recovery plans.
The Allegheny Intermediate Unit School System, Pennsylvania, U.S.A.
School A, The Allegheny Intermediate Unit school system, DID NOT have to engage with the criminals and were able to use the services of a third-party to get their critical data recovered quickly. When you read the wording on various articles related to this incident, it appears that the school system quickly engaged with their cyber insurance carrier. Their insurance carrier mobilized resources quickly to identify and remediate the attack and then restored from existing backs of critical data. THIS is how the process is supposed to work.
The University of Maastricht, The Netherlands
School B, The University of Maastricht, did not have an adequate plan in place and had to completely shut down information systems and pay the ransom in order to decrypt their computers and servers. The timeline on this attack is interesting; the original compromise occurred a little over two months before their networks were ransomed. Had they had an extra layer of defense like the RealTime Cyber Defense package, they could have potentially caught the attack during this phase.
LESSONS LEARNED?
The lessons that a school [or any business] that has been through an event like this one will make them better at risk-based decisions going forward. Now they know that they are vulnerable to an attack like this and will take positive steps to introduce better prevention and detection processes.
Todd Swartzman, RealTime CISO
TODD’S TAKE ON THE RECOVERY:
After paying the ransom, it was pretty fast to decrypt that many systems and perhaps most were using the same decryption keys – some victims aren’t that lucky and have to juggle hundreds or thousands of decryption keys that really slows down recovery. Part of the decision to pay was based on how much quicker it can be to decrypt machines rather than reloading from scratch. The statement by the university indicates that they may not have had backups of some of their critical data.
summary:
Be sure to have a good backup in place;
Cyber insurance is a great idea;
Adding a cyber security plan could have helped detect the internal attack during the months they “inside” the system rather than waiting.
