Mid-Year Threat Report Shows Massive Increase in Ransomware Attacks
Last month, SonicWall published a mid-year update of its Cyber Threat Report which confirmed there has been a major increase in cyberattacks since 2020. In the first 6 months of 2021, cryptojacking attacks increased by 23%, encrypted threats rose by 26%, IoT attacks rose by 59%, and there was a 151% increase in ransomware attacks compared to the corresponding period last year. Ransomware attacks have been steadily increasing since Q1, 2020, but the rate of increase jumped considerably between Q1 and Q2, 2021, rising to a Q2 total of 188.9 million attempted attacks: an increase of 63.1% from the previous quarter. In June alone there were 78.4 million attempted ransomware attacks, which is more than the total number of attacks in the second quarter of 2020 and almost half of the total number of attempted ransomware attacks in all of 2019. In total, there were 304.7 million attempted ransomware attacks in the first half of 2021. “Even if we don’t record a single ransomware attempt in the entire second half (which is irrationally optimistic), 2021 will already go down as the worst year...
Contact Tracing Survey Data of 750,000 Hoosiers Exposed Online
The personal information of 750,000 Hoosiers collected as part of a COVID-19 contact tracing survey conducted by the Indiana Department of Health has been exposed online and downloaded by a company not authorized to access the data. The survey included information such as names, addresses, dates of birth, emails, and information on gender, ethnicity and race. The Indiana Department of Health was notified about the unauthorized access on July 2, 2021 and immediately took steps to secure the data to prevent further unauthorized access. According to Tracy Barnes, the Chief Information Officer of the state of Indiana, the company that accessed and downloaded the data was a firm “that intentionally looks for software vulnerabilities, then reaches out to seek business.” Last week, the Indiana Department of Health obtained a signed “certificate of destruction” from the company confirming the downloaded data had been permanently destroyed and that no further copies of the data had been retained. The company also confirmed the downloaded data had not been disclosed to any other company or...
1.4 Million Individuals Affected by St. Joseph’s/Candler Ransomware Attack
Around 4 a.m. on Thursday June 17, 2021, St. Joseph’s/Candler (SJ/C) hospital system in Savannah, GA suffered a ransomware attack. Upon detection of suspicious network activity, SJ/C immediately took steps to isolate and secure its systems. The attack prevented access to computer systems and emergency protocols were implemented, with staff reverting to pen and paper to record patient data. SJ/C notified law enforcement about the security breach and launched an investigation. Assisted by third party cybersecurity firms, SJ/C determined the hackers first gained access to its systems on December 18, 2020 and continued to have access to those systems until June 17, 2021, when the ransomware was deployed. “Patient care operations continue at our facilities using established back-up processes and other downtime procedures,” explained SJ/C in a statement shortly after the attack was detected. “Our physicians, nurses and staff are trained to provide care in these types of situations and are committed to doing everything they can to mitigate disruption and provide uninterrupted care to our...
Scripps Health Ransomware Attack Cost Increases to Almost $113 Million
Ransomware attacks on hospitals can cause huge financial losses, as the Ryuk ransomware attack on Universal Health Services showed. UHS is one of the largest healthcare providers in the United States, and operates 26 acute care hospitals, 330 behavioral health facilities, and 41 outpatient facilities. UHS said in March 2021 that the September 2020 ransomware attack resulted in $67 million in pre-tax losses due the cost of remediation, loss of acute care services, and other expenses incurred due to the attack. While the losses suffered by UHS were significant, the ransomware attack on Scripps Health has proven to be far more expensive. Scripps Health is a California-based nonprofit operator of 5 hospitals and 19 outpatient facilities in the state. In the May 2021 ransomware attack, Scripps Health lost access to information systems at two of its hospitals, staff couldn’t access the electronic medical record system, and its offsite backup servers were also affected. Without access to critical IT systems, Scripps Health was forced to re-route stroke and heart attack patients from four...
CISA Issues Warning About Blackberry’s QNX Vulnerability Affecting Critical Infrastructure
The DHS’ Cybersecurity and Infrastructure Security Agency (CISA) has issued a security alert warning about a vulnerability affecting Blackberry’s QNX Real Time Operating System (RTOS), which is extensively used by critical infrastructure organizations and affects multiple consumer, medical, and industrial networks. The vulnerability is one of 25 that are collectively known as BadAlloc, which affect multiple IoT and OT systems. The flaws are memory allocation integer overflow or wraparound issues in memory allocation functions used in real-time operating systems (RTOS), embedded software development kits (SDKs), and C standard library (libc) implementations. On August 17, 2021, Blackberry announced that its QNX products were affected by one of the BadAlloc vulnerabilities – CVE-2021-22156. The flaw could be exploited by a remote attacker to cause a denial-of-service condition, or even achieve remote code execution, with the latter potentially allowing an attacker to take control of highly sensitive systems. The flaw affects the calloc() function in the C runtime library of...
