7. Vulnerabilities in Sino Track GPS Devices Allow Remote Control and Tracking

Timestamp: [07:20]

The Cybersecurity and Infrastructure Security Agency (CISA) has issued warnings about vulnerabilities in Sino Track GPS devices, which could have dire consequences for vehicle security and privacy.

• Vulnerabilities Identified:

  • CVE Scores: 8.3 and 8.6
  • Potential Exploits:
    • Accessing a vehicle's device profile
    • Tracking its location
    • Cutting power to the fuel pump

• Security Lapses:

  • Default Credentials: Sino Track devices utilize a universal default password and do not mandate password changes during setup.
  • Device ID Exposure: Usernames are easily obtainable from the device label, making unauthorized access straightforward.

• CISA's Recommendation:

  "CISA is urging users to change their default passwords and hide the device IDs." – Steve Prentiss [07:35]

Currently, there have been no public records of these vulnerabilities being exploited, but the potential risks necessitate immediate action from device owners.

8. Innovative Data Exfiltration via Smartwatches in Air-Gapped Systems

Timestamp: [07:45]

Introducing a novel threat vector, a researcher from Ben Gurion University of the Negev has developed a method named Smart Attack for exfiltrating data from air-gapped systems using smartwatches.

• Attack Process:

  • Technique: Utilizes the smartwatch's built-in microphone to capture ultrasonic signals ranging from 18 to 22 kHz.
  • Prerequisite: Requires prior infiltration to install malware that can transmit data via the infected machine's speakers at inaudible frequencies.

• Researcher Insight:

  "Smart Attack uses a smartwatch's built-in microphone to capture covert ultrasonic signals within range of 18 to 22kHz." – Mordechai Guri [07:50]

While the method is sophisticated, its practicality depends on specific environmental conditions and the initial breach, highlighting the evolving nature of cyber threats.

These are the cybersecurity headlines for Friday, June 13, 2025. I'm Steve Prentiss. Hackers attacks target Microsoft Entra ID accounts using pen testing tool Researchers at Proofpoint are describing a hacking campaign that is using the Team Filtration Pen testing framework to target more than 80 Microsoft Entra ID accounts at hundreds of organizations worldwide. Blame is being placed on a threat actor called UnksneakyStrike. The attacks occurred from December of last year through to March. Team Filtration is a legitimate pen testing tool first published in 2022 by trusted SEC Red Team researcher Melvin Langvick. It is thought that for this attack, the gang quote used AWS servers across multiple regions and used a sacrificial office365 account with a Business Basic license to abuse Microsoft Teams API for account enumeration. Google Cloud and Cloudflare outages reported yesterday. These outages affected services such as Google Home, Nest, Snapchat, Discord, Shopify and Spotify, as well as creating Access authentication failures and Cloudflare Zero Trust warp connectivity issues. DownDetector received tens of thousands of reports with impacted users experiencing Cloudflare and Google Cloud server connection, website and hosting problems. The issue started around 1:15pm Eastern Time and was being resolved throughout the afternoon. House Homeland Chairman Mark Green Announces His Departure the Tennessee Republican who chairs the House Homeland Security Committee has announced his pending retirement from Congress, which could place additional pressures on the fate of cyber legislation, cyberscoop said, quote. As head of the committee, Green championed cyber workforce legislation as his top priority and recently and he called for a vote on the measure on the House floor. He has supported reauthorizing a cybersecurity 2015 information sharing law that expires in September, end quote. Green said he would leave for an unspecified job in the private sector following a final vote on the President's big beautiful bill. Fog ransomware attack uses employee monitoring software and a pen testing tool. This attack on a financial institution in Asia in May deployed the Fog ransomware tool by using a legitimate, legitimate employee monitoring software called Sciteca paired with the GC2 penetration testing tool. A report from Symantec says the GC2 allows an attacker to execute commands on target machines using Google sheets or Microsoft SharePoint list and exfiltrate files using Google Drive or Microsoft SharePoint documents. Although the researchers are not sure of the role played by sciteca, James Maud, who is field CTO at Beyond Trust, said threat actors typically use legitimate commercial software during attacks to reduce the chances that their intrusions are detected by security tools.

The update is a revised version of the Windows 11 cumulative update released during this month's patch Tuesday. Graphite spyware used in Apple iOS zero click attacks on journalists A forensic investigation by Citizen Lab has confirmed that Paragon's graphite spyware was used in zero click attacks targeting iPhones of at least two journalists in Europe. The attacks exploited a then unknown vulnerability with a CVE number in iOS 18.1.1, which allowed malicious photographs or videos shared via icloud links to compromised devices. Apple notified the victims on April 29, identifying the spyware as advanced. The graphite platform is believed to be part of Paragon's mercenary spyware operations. The flaw has since been patched by Apple. Sino Track GPS device flaws lead to remote vehicle control and location tracking CISA is warning of two vulnerabilities in SinoTrack GPS Track GPS devices that can be exploited to access a vehicle's device profile, track its location, or even cut power to the fuel pump, depending on the model. The two vulnerabilities have CVE numbers and have CVSS scores of 8.3 and 8.6. SinoTrack apparently uses the same default password for all units and does not require changing it during setup. Since the username is simply the device ID printed on the label, someone could easily gain access either by physically seeing the device or even spotting it in online photos, such as on ebay. CISA is urging users to change their default passwords and hide the device IDs no public exploitation of the vulnerabilities has yet been recorded. Air gapped data could be stolen via smartwatches, says researcher A new technique for exfiltrating data from air gapped systems through a smartwatch is being developed by a researcher from the Ben Gurion University of the Negev. Mordechai Guri says the technique, called Smart Attack, uses a smartwatch's built in microphone to capture covert ultrasonic signals within range of 18 to 22kHz, successfully enabling data theft based on certain environmental conditions. It must be said, however, that to succeed, a previous infiltration is required to implant malware that would transmit information using the infected machine's speakers in a frequency range that makes sounds inaudible to humans.
