A now-patched security flaw in the Opera web browser could have enabled a malicious extension to gain unauthorized, full access to private APIs. The attack, codenamed CrossBarking , could have made it possible to conduct actions such as capturing screenshots, modifying browser settings, and account hijacking, Guardio Labs said. To demonstrate the issue, the company said it managed to publish a seemingly harmless browser extension to the Chrome Web Store that could then exploit the flaw when installed on Opera, making it an instance of a cross-browser-store attack. "This case study not only highlights the perennial clash between productivity and security but also provides a fascinating glimpse into the tactics used by modern threat actors operating just below the radar," Nati Tal, head of Guardio Labs, said in a report shared with The Hacker News. The issue has been addressed by Opera as of September 24, 2024, following responsible disclosure. That said, this is not th...

Cybersecurity researchers have uncovered an ongoing malvertising campaign that abuses Meta's advertising platform and hijacked Facebook accounts to distribute an information stealer known as SYS01stealer. "The hackers behind the campaign use trusted brands to expand their reach," Bitdefender Labs said in a report shared with The Hacker News. "The malvertising campaign leverages nearly a hundred malicious domains, utilized not only for distributing the malware but also for live command and control (C2) operations, allowing threat actors to manage the attack in real-time." SYS01stealer was first documented by Morphisec in early 2023, describing attack campaigns targeting Facebook business accounts using Google ads and fake Facebook profiles that promote games, adult content, and cracked software. Like other stealer malware, the end goal is to steal login credentials, browsing history, and cookies. But it's also focused on obtaining Facebook ad and busin...

Cybersecurity researchers have discovered a new malicious Python package that masquerades as a cryptocurrency trading tool but harbors functionality designed to steal sensitive data and drain assets from victims' crypto wallets. The package, named "CryptoAITools," is said to have been distributed via both Python Package Index (PyPI) and bogus GitHub repositories. It was downloaded over 1,300 times before being taken down from PyPI. "The malware activated automatically upon installation, targeting both Windows and macOS operating systems," Checkmarx said in a new report shared with The Hacker News. "A deceptive graphical user interface (GUI) was used to distract vic4ms while the malware performed its malicious ac4vi4es in the background." The package is designed to unleash its malicious behavior immediately after installation through code injected into its "__init__.py" file that first determines if the target system is Windows or macOS ...

A little over three dozen security vulnerabilities have been disclosed in various open-source artificial intelligence (AI) and machine learning (ML) models, some of which could lead to remote code execution and information theft. The flaws, identified in tools like ChuanhuChatGPT, Lunary, and LocalAI, have been reported as part of Protect AI's Huntr bug bounty platform. The most severe of the flaws are two shortcomings impacting Lunary, a production toolkit for large language models (LLMs) - CVE-2024-7474 (CVSS score: 9.1) - An Insecure Direct Object Reference (IDOR) vulnerability that could allow an authenticated user to view or delete external users, resulting in unauthorized data access and potential data loss CVE-2024-7475 (CVSS score: 9.1) - An improper access control vulnerability that allows an attacker to update the SAML configuration, thereby making it possible to log in as an unauthorized user and access sensitive information Also discovered in Lunary is anot...

Sherlock Holmes is famous for his incredible ability to sort through mounds of information; he removes the irrelevant and exposes the hidden truth. His philosophy is plain yet brilliant: "When you have eliminated the impossible, whatever remains, however improbable, must be the truth." Rather than following every lead, Holmes focuses on the details that are needed to move him to the solution. In cybersecurity, exposure validation mirrors Holmes' approach: Security teams are usually presented with an overwhelming list of vulnerabilities, yet not every vulnerability presents a real threat. Just as Holmes discards irrelevant clues, security teams must eliminate exposures that are unlikely to be exploited or do not pose significant risks. Exposure validation (sometimes called Adversarial Exposure Validation) enables teams to concentrate on the most significant issues and minimize distractions. Similar to Holmes' deductive reasoning, validation of exposures directs organizations towa...

The Dutch National Police, along with international partners, have announced the disruption of the infrastructure powering two information stealers tracked as RedLine and MetaStealer . The takedown, which took place on October 28, 2024, is the result of an international law enforcement task force codenamed Operation Magnus that involved authorities from the U.S., the U.K., Belgium, Portugal, and Australia. Eurojust, in a statement published today, said the operation led to the shut down of three servers in the Netherlands and the confiscation of two domains (fivto[.]online and spasshik[.]xyz). In total, over 1,200 servers in dozens of countries are estimated to have been used to run the malware. As part of the efforts, one administrator has been charged by the U.S. authorities and two people have been arrested by the Belgian police, the Politie said , adding one of them has since been released, while the other remains in custody. The U.S. Department of Justice (DoJ) has charge...

The U.S. government (USG) has issued new guidance governing the use of the Traffic Light Protocol ( TLP ) to handle threat intelligence information shared between the private sector, individual researchers, and Federal Departments and Agencies. "The USG follows TLP markings on cybersecurity information voluntarily shared by an individual, company, or other any organization, when not in conflict with existing law or policy," it said . "We adhere to these markings because trust in data handling is a key component of collaboration with our partners." In using these designations, the idea is to foster trust and collaboration in the cybersecurity community while ensuring that the information is shared in a controlled manner, the government added. TLP is a standardized framework for classifying and sharing sensitive information. It comprises four colors -- Red, Amber, Green, and White -- that determine how it can be distributed further and only to those who need to...

More than six years after the Spectre security flaw impacting modern CPU processors came to light, new research has found that the latest AMD and Intel processors are still susceptible to speculative execution attacks. The attack, disclosed by ETH Zürich researchers Johannes Wikner and Kaveh Razavi, aims to undermine the Indirect Branch Predictor Barrier ( IBPB ) on x86 chips, a crucial mitigation against speculative execution attacks. Speculative execution refers to a performance optimization feature wherein modern CPUs execute certain instructions out-of-order by predicting the branch a program will take beforehand, thus speeding up the task if the speculatively used value was correct. If it results in a misprediction, the instructions, called transient, are declared invalid and squashed, before the processor can resume execution with the correct value. While the execution results of transient instructions are not committed to the architectural program state, it's still ...
