Google Adds New Pixel Security Features to Block 2G Exploits and Baseband Attacks

Oct 03, 2024 Mobile Security / Technology
Google has revealed the various security guardrails that have been incorporated into its latest Pixel devices to counter the rising threat posed by baseband security attacks. The cellular baseband (i.e., modem) refers to a processor on the device that's responsible for handling all connectivity, such as LTE, 4G, and 5G, with a mobile phone cell tower or base station over a radio interface. "This function inherently involves processing external inputs, which may originate from untrusted sources," Sherk Chung and Stephan Chen from the Pixel team, and Roger Piqueras Jover and Ivan Lozano from the company's Android team said in a blog post shared with The Hacker News. "For instance, malicious actors can employ false base stations to inject fabricated or manipulated network packets. In certain protocols like IMS (IP Multimedia Subsystem), this can be executed remotely from any global location using an IMS client." What's more, the firmware powering the

5 Must-Have Tools for Effective Dynamic Malware Analysis

Oct 02, 2024 Malware Analysis / Threat Detection
Dynamic malware analysis is a key part of any threat investigation. It involves executing a sample of a malicious program in the isolated environment of a malware sandbox to monitor its behavior and gather actionable indicators. Effective analysis must be fast, in-depth, and precise. These five tools will help you achieve it with ease. 1. Interactivity Having the ability to interact with the malware and the system in real-time is a great advantage when it comes to dynamic analysis. This way, you can not only observe its execution but also see how it responds to your inputs and triggers specific behaviors.  Plus, it saves time by allowing you to download samples hosted on file-sharing websites or open those packed inside an archive, which is a common way to deliver payloads to victims. The initial phishing email containing the malicious pdf and password for the archive Check out this sandbox session in the ANY.RUN sandbox that shows how interactivity is used for analyzing the en

Critical Flaws in Tank Gauge Systems Expose Gas Stations to Remote Attacks

Critical Flaws in Tank Gauge Systems Expose Gas Stations to Remote Attacks

Sep 30, 2024 Operational Technology / Network Security
Critical security vulnerabilities have been disclosed in six different Automatic Tank Gauge (ATG) systems from five manufacturers that could expose them to remote attacks. "These vulnerabilities pose significant real-world risks, as they could be exploited by malicious actors to cause widespread damage, including physical damage, environmental hazards, and economic losses," Bitsight researcher Pedro Umbelino said in a report published last week. Making matters worse, the analysis found that thousands of ATGs are exposed to the internet, making them a lucrative target for malicious actors looking to stage disruptive and destructive attacks against gas stations, hospitals, airports, military bases, and other critical infrastructure facilities. ATGs are sensor systems designed to monitor the level of a storage tank (e.g., fuel tank) over a period of time with the goal of determining leakage and parameters. Exploitation of security flaws in such systems could therefore have

Chinese Hackers Infiltrate U.S. Internet Providers in Cyber Espionage Campaign

Chinese Hackers Infiltrate U.S. Internet Providers in Cyber Espionage Campaign

Sep 26, 2024 Cyber Espionage / Hacking
Nation-state threat actors backed by Beijing broke into a "handful" of U.S. internet service providers (ISPs) as part of a cyber espionage campaign orchestrated to glean sensitive information, The Wall Street Journal reported Wednesday. The activity has been attributed to a threat actor that Microsoft tracks as Salt Typhoon, which is also known as FamousSparrow and GhostEmperor. "Investigators are exploring whether the intruders gained access to Cisco Systems routers, core network components that route much of the traffic on the internet," the publication was quoted as saying, citing people familiar with the matter. The end goal of the attacks is to gain a persistent foothold within target networks, allowing the threat actors to harvest sensitive data or launch a damaging cyber attack. GhostEmperor first came to light in October 2021, when Russian cybersecurity company Kasperksy detailed a long-standing evasive operation targeting Southeast Asian targets in
Expert Tips on How to Spot a Phishing Link

Expert Tips on How to Spot a Phishing Link

Sep 25, 2024 Cyber Awareness / Threat Detection
Phishing attacks are becoming more advanced and harder to detect, but there are still telltale signs that can help you spot them before it's too late. See these key indicators that security experts use to identify phishing links: 1. Check Suspicious URLs  Phishing URLs are often long, confusing, or filled with random characters. Attackers use these to disguise the link's true destination and mislead users.  The first step in protecting yourself is to inspect the URL carefully. Always ensure it begins with "HTTPS," as the "s" indicates a secure connection using an SSL certificate.  However, keep in mind that SSL certificates alone are not enough. Cyber attackers have increasingly used legitimate-looking HTTPS links to distribute malicious content. This is why you should be suspicious of links that are overly complex or look like a jumble of characters.  Tools like ANY.RUN's Safebrowsing allow users to check suspicious links in a secure and isolated environment w
