In this week's Cybersecurity Current Events, we examine critical developments ranging from car hacking and healthcare security to high-profile vulnerabilities in Microsoft Windows and Apache Solr. With more topics this week than usual, and a news cycle constantly filled with new breaches and tech announcements, staying informed and proactive in addressing cybersecurity challenges remains a priority for any IT professional, tech-savvy enthusiast, or concerned citizen. Let’s dive into the key events shaping the week.
1. Cybersecurity Threats to Modern Cars
Summary: Hackers are increasingly targeting modern vehicles, exploiting vulnerabilities in their connected systems, posing severe safety risks. With the automotive industry’s rapid shift toward connected and autonomous vehicles, cybersecurity has become a pressing concern. Security researchers have uncovered a significant vulnerability in Subaru's Starlink service, which could have allowed attackers to seize control of vehicles and access sensitive customer data.By leveraging basic information such as a license plate and the owner’s last name or email address, hackers could exploit the system in multiple ways. This includes remotely starting or stopping the car, locking and unlocking doors, and tracking the vehicle’s real-time location. Furthermore, they could retrieve personally identifiable information (PII), such as emergency contacts, billing details, and the vehicle’s PIN. Most alarmingly, attackers could access over a year’s worth of highly accurate location data—within five meters—enabling them to create a detailed profile of the victim’s movements. Similar incidents have occured with other car brands such as Kia.
Timeline: Reported on January 25, 2025
Threat Actors: Unspecified cybercriminal groups specializing in IoT and automotive exploits. The vulnerability originated from flaws in the Starlink admin portal, including an unsecured password reset API endpoint and inadequate safeguards against bypassing two-factor authentication (2FA).
Key Implications:
- Endangerment of driver and passenger safety.
- Financial and reputational risks for automobile manufacturers.
- Increased regulatory scrutiny on connected vehicle security.
Actionable Steps:
- Regularly update vehicle software to patch known vulnerabilities.
- Avoid connecting cars to untrusted networks or devices.
- Encourage manufacturers to adopt rigorous cybersecurity protocols during vehicle development.

5. Ivanti Connect Secure Backdoors
Summary: Security researchers uncovered 379 backdoors in Ivanti Connect Secure, a popular VPN solution. These vulnerabilities could allow attackers to execute remote code, access sensitive data, and move laterally within compromised networks. As of Friday, Censys identified nearly 33,000 Ivanti Connect Secure devices that were publicly exposed to the internet.
Timeline: Disclosed January 8, 2025, with most recent update January, 24, 2025.
Threat Actors: Advanced persistent threat (APT) groups exploiting VPN vulnerabilities.
Key Implications:
- Heightened risks for organizations relying on Ivanti for secure connectivity.
- Potential for data theft and ransomware deployment.
- Damage to Ivanti’s reputation and user trust.
Actionable Steps:
- Immediately apply patches released by Ivanti.

6. TalkTalk Investigates Data Breach
Summary: TalkTalk is investigating claims of a data breach after a hacker alleged the theft of customer information, including names, addresses, and payment details. The company is working to determine the legitimacy of the claims and secure its systems. It is good to take note that TalkTalk was fined £400,000 following a 2015 data breach in which hackers stole the personal data of 157,000 customers, including sensitive financial information.
Timeline: TalkTalk representation made a statement on January 21, 2025. The investigation is still on-going.
Threat Actors: A person operating under the pseudonym “b0nd” has claimed responsibility for stealing the personal data of over 18.8 million current and former TalkTalk subscribers. TalkTalk continues to investigate but confidently states 18.8 million is an extremely exaggerated number. Screenshots shared by b0nd indicate that the data was stolen from CSG’s Ascendon platform.
