NSA Releases Guidance on Eliminating Weak Encryption Protocols
The National Security Agency (NSA) has released guidance to help organizations eliminate weak encryption protocols, which are currently being exploited by threat actors to decrypt sensitive data. Transport Layer Security (TLS) and Secure Sockets Layer (SSL) protocols were developed to create protected channels using encryption and authentication to ensure the security of sensitive data between a server and a client. The algorithms used by these protocols to encrypt data have since been updated to improve the strength of encryption, but obsolete protocol configurations are still in use. New attacks have been developed that exploit weak encryption and authentication protocols, which are being actively used by threat actors to decrypt and obtain sensitive data. The NSA explains that most products that use obsolete TLS versions, cipher suites, and key exchange methods have been updated, but implementations have often not kept up and continued use of these out-of-date TLS configurations carries an elevated risk of exploitation. Continued use of outdated protocols provides a false sense...
Healthcare Industry Cyberattacks Increase by 45%
In the fall of 2020, a warning was issued to the healthcare and public health sector following a spike in ransomware activity. The joint CISA, FBI, and HHS cybersecurity advisory explained that the healthcare industry was being actively targeted by threat actors with the aim of infecting systems with ransomware. Several ransomware gangs had stepped up attacks on the healthcare and public health sector, with the Ryuk and Conti operations the most active. A new report from Check Point shows attacks continued to increase in November and December 2020, when there was a 45% increase in cyber-attacks on healthcare organizations globally. The increase was more than double the percentage rise in attacks on all industry sectors worldwide over the same period. Globally, there was an average of 626 cyberattacks on healthcare organizations each week in November and December, compared to 430 attacks in October. The vectors used in the attacks have been varied, with Check Point researchers identifying an increase in ransomware, botnet, remote code execution, and DDoS attacks in November and...
Hidden Backdoor Identified in 100,000 Zyxel Devices
A vulnerability has been identified in Zyxel devices such as VPN gateways, firewalls, and access point (AP) controllers that could be exploited by threat actors to gain remote administrative access to the devices. By exploiting the vulnerability, threat actors would be able to make changes to firewall settings, allow/deny certain traffic, intercept traffic, create new VPN accounts, make internal services publicly accessible, and gain access to internal networks behind Zyxel devices. Around 100,000 Zyxel devices worldwide have the vulnerability. Zyxel manufacturers networking equipment and its devices are popular with small to medium sized businesses and are also used by large enterprises and government agencies. The vulnerability, tracked as CVE-2020-29583, was identified by Niels Teusink of the Dutch cybersecurity firm EYE, who discovered a hidden user account in the latest version of Zyxel firmware (4.60 patch 0). The user account, zyfwp, which was not visible in the user interface of the products, was discovered to have a hardcoded plain-text password which Teusink found in one...
Breaches Reported by Northwestern Memorial Hospital, Apex Laboratory, and Five Points Eye Care
Northwestern Memorial Hospital in Chicago discovered a former temporary worker may have inappropriately viewed the medical records of certain patients while employed at the hospital. The unauthorized access was detected on December 2, 2020. A review of access logs revealed the individual viewed patient records without a work-related purpose for doing so between October 27, 2020 and December 2, 2020. The information potentially viewed was limited to patient names, addresses, and treatment information. The worker did not have access to financial information or Social Security numbers. Northwestern Memorial Hospital issued a statement about the privacy breach confirming the records of 682 patients may have been viewed and confirmed that the temporary worker is no longer employed by the hospital. It is unclear why the records were accessed. All affected patients are being notified about the privacy breach by mail and the incident has been reported to appropriate authorities. The HHS’ Office for Civil Rights breach portal shows 682 patients were affected by the breach. Apex...
Largest Healthcare Data Breaches in 2020
2020 was the worst ever year for healthcare industry HIPAA compliance data breaches. Some 616 data breaches of 500 or more records were reported to the HHS’ Office for Civil Rights. 28,756,445 healthcare records were exposed, compromised, or impermissibly disclosed in those breaches, which makes 2020 the third worst year in terms of the number of breached healthcare records. The chart below clearly shows how healthcare industry data breaches have steadily increased over the past decade and the sharp rise in breaches in the past two years. The Largest Healthcare Data Breaches in 2020 When a breach occurs at a business associate of a HIPAA-covered entity, it is often the covered entity that reports the breach rather than the business associate. In 2020, a massive data breach was experienced by the cloud service provider Blackbaud Inc. Hackers gained access to its systems and stole customer fundraising databases before deploying ransomware. Blackbaud was issued with a ransom demand and a threat that the stolen data would be released publicly if the ransom was not paid. Blackbaud...
