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...
Cyberattack Forces Memorial Health System to Divert Patients to Alternate Hospitals
Marietta, OH-based Memorial Health System has been forced to divert emergency care patients due to a suspected ransomware attack. The cyberattack was detected on August 14, 2021, and forced the health system to shut down IT systems to contain the attack. Emergency protocols were implemented due to the lack of access to essential IT systems, and the staff has been working with paper charts. Memorial Health System operates three hospitals in Ohio and West Virginia, all of which have been affected by the attack. Since electronic health records were not accessible, patient safety was potentially put at risk, so the decision was taken to divert emergency patents. “We will continue to accept: STEMI, STROKE and TRAUMA patients at Marietta Memorial Hospital. Belpre and Selby are on diversion for all patients due to radiology availability. It is in the best interest of all other patients to be taken to the nearest accepting facility,” according to an August 15 press release. “If all area hospitals on are diversion, patients will be transported to the emergency department closest to where...

Password Reuse is Rife and Security Awareness Training Has Little Effect
An overwhelming majority of employees are aware what constitutes a strong password, but 53% of employees do not always set a strong password to protect their accounts. When it comes to setting unique passwords for all accounts, even fewer employees adhere to the best practice, according to a survey recently conducted by My1login on 1,000 employees and 1,000 business leaders. 62% of employees said they reuse personal passwords for their business accounts or vice versa. Healthcare employees were the worst when it comes to password reuse, with 94% of surveyed healthcare employees admitting to reusing passwords across multiple accounts, with similarly high numbers of employees in education (91%) and the public sector (83%) reusing passwords. These three verticals also rated the highest for the use of personal passwords for business applications, with education coming top (75%) followed by healthcare (68%) and the public sector (61%). Across all industry sectors, 87% of employees said they reused passwords across business applications. Password reuse is a security risk. If a password is...
