The Good

Before we get ready to wrap up for the week, let’s glance through the weekly updates in the world of cybersecurity. We’ll begin with the positive developments. Twelve cybersecurity service and software providers have formed the Operational Technology Cyber Security Alliance (OTCSA) with the aim of protecting operational technology in critical and industrial infrastructure from cyberthreats. The Federal Bureau of Investigation (FBI) has expanded its tools and resources to assist in protecting the U.S. elections from cyber attacks. Meanwhile, researchers have developed an open-source tool called VisibleV8, which can detect malicious programs that evade existing malware detection systems.

  • Twelve cybersecurity service and software providers have come together to form a global alliance called Operational Technology Cyber Security Alliance (OTCSA). This alliance will focus on protecting the operational technology in critical and industrial infrastructure from cyber threats. The membership is said to be open to any company that works with OT systems or critical infrastructure.
  • The Federal Bureau of Investigation (FBI) has updated its resources and tools to help protect the U.S. elections from cyberattacks. The FBI along with the Department of Homeland Security (DHS) and the Director of National Intelligence (DNI) has released a number of short videos. These online tutorials highlight social engineering and foreign influence cybersecurity measures for political campaigns.
  • Researchers from North Carolina State University have developed an open-source tool called VisibleV8 that can track and record JavaScript program behavior without alerting websites that run the programs. This tool runs in the Chrome browser and can detect malicious programs, that may not be detected by malware detection systems. This tool is said to contain only 600 lines of code.
  • The Federal Trade Commission (FTC) has released an article promoting the International Charity Fraud Awareness Week (ICFAW). This year’s ICFAW is from October 21 to 25. Key participants of this coordinated campaign include the British Council, Chartered Accountants Worldwide, Australian Charities and Not-for-profits Commission, and New Zealand Charities Service, among others.

The Bad

With two cybersecurity firms disclosing the details of security compromises they fell victim to, this week has all of us on our toes. Cybersecurity software provider Avast disclosed a security breach that was similar to the 2017 CCleaner incident. In similar news, VPN service provider NordVPN disclosed a breach that affected one of its data centers in March 2018. Meanwhile, a distributed denial-of-service (DDoS) attack hit Amazon Web Services and lasted for almost 8 hours.

  • Internet security software provider Avast disclosed that a security breach was detected on September 23, 2019. The attackers compromised an employee’s VPN credentials to gain access to an account that was not protected using a multi-factor authentication solution. The attack is said to be similar in nature to the infamous CCleaner 2017 incident.
  • NordVPN disclosed a data breach that affected one of its data centers in March 2018. The company said that the breach happened because of poor configuration on a third-party data center. No other servers or user credentials are said to be impacted.
  • Amazon Web Services was hit by a distributed denial-of-service (DDoS) attack that lasted for around 8 hours. The attack primarily impacted the company's Router 53 DNS web service. This caused service outages for many websites and parts of AWS being taken off the internet.
  • Personal and travel information of thousands of users, including the U.S. government and military personnel, was exposed due to a leaky database belonging to reservations management system Autoclerk. This database was reportedly hosted by AWS in the U.S. with over 179GB of data. The exposed data includes full names, dates of birth, home addresses, phone numbers, unencrypted login credentials, dates and costs of travel, and masked credit card details.
  • A misconfigured MongoDB database with around 2.8 million records of customer data was found exposed. The database belongs to communications and IT services firm CenturyLink. Compromised information includes customer names, email addresses, phone numbers, and addresses.

  • Financial services provider Billtrust suffered a ransomware attack that impacted some of its computing systems. The company said that no customer data was compromised as a result of this attack. Billtrust is in the final stage of bringing all its systems online from backups.
  • Canada Post disclosed that some online customer accounts had recorded unauthorized access. Due to this, the company is resetting the passwords of all online accounts. The company said that there was no data breach, and the credentials were stolen from other data breaches, and customers were reusing the same credentials for their Canada Post account.
  • Kalispell Regional Healthcare (KRH) was the victim of a targeted phishing attack that compromised the login credentials of several employees. This may have potentially led to the exposure of personal information of the patients including name, date of birth, address, Social Security Number, medical record number, telephone number, and more. Although officials have not found any indication of the data misuse yet, notification letters were mailed to potentially impacted patients.
  • Johnson City in Tennessee suffered a ransomware attack that affected some of the municipality’s computer systems. The ransom note asked city officials to get in touch with an email address for payment instructions and claimed to have encrypted the government’s backups. The municipality has refused to pay the fine and is working on restoring the impacted systems.
  • A scripting error on the National Neurology Registry’s website is said to have made the private information of over 17,000 patients vulnerable to exposure. It may have potentially allowed unauthorized access to a confidential database that contains phone numbers and addresses. The Health Ministry, along with the National Cyber Security Agency (NACSA), Malaysia Communications and Multimedia Commission (MCMC), and Cybersecurity Malaysia are working on investigating this incident.
  • A new phishing campaign that has targeted various humanitarian organizations around the world, including the Red Cross, the United Nations, and UNICEF has been discovered.
