New Flaws in Microsoft macOS Apps Could Allow Hackers to Gain Unrestricted Access

New Flaws in Microsoft macOS Apps Could Allow Hackers to Gain Unrestricted Access

Sep 03, 2024 Endpoint Security / Cyber Threat
Eight vulnerabilities have been uncovered in Microsoft applications for macOS that an adversary could exploit to gain elevated privileges or access sensitive data by circumventing the operating system's permissions-based model, which revolves around the Transparency, Consent, and Control ( TCC ) framework. "If successful, the adversary could gain any privileges already granted to the affected Microsoft applications," Cisco Talos said . "For example, the attacker could send emails from the user account without the user noticing, record audio clips, take pictures, or record videos without any user interaction." The shortcomings span various applications such as Outlook, Teams, Word, Excel PowerPoint, and OneNote. The cybersecurity company said malicious libraries could be injected into these applications and gain their entitlements and user-granted permissions, which could then be weaponized for extracting sensitive information depending on the access granted

North Korean Hackers Deploy FudModule Rootkit via Chrome Zero-Day Exploit

Aug 31, 2024 Rootkit / Threat Intelligence
A recently patched security flaw in Google Chrome and other Chromium web browsers was exploited as a zero-day by North Korean actors in a campaign designed to deliver the FudModule rootkit. The development is indicative of the persistent efforts made by the nation-state adversary, which had made a habit of incorporating rafts of Windows zero-day exploits into its arsenal in recent months. Microsoft, which detected the activity on August 19, 2024, attributed it to a threat actor it tracks as Citrine Sleet (formerly DEV-0139 and DEV-1222), which is also known as AppleJeus, Labyrinth Chollima, Nickel Academy, and UNC4736 . It's assessed to be a sub-cluster within the Lazarus Group (aka Diamond Sleet and Hidden Cobra). It's worth mentioning that the use of the AppleJeus malware has been previously also attributed by Kaspersky to another Lazarus subgroup called BlueNoroff (aka APT38, Nickel Gladstone, and Stardust Chollima), indicative of the infrastructure and toolset sharin

New QR Code Phishing Campaign Exploits Microsoft Sway to Steal Credentials

Aug 28, 2024 Phishing Attack / Data Breach
Cybersecurity researchers are calling attention to a new QR code phishing (aka quishing) campaign that leverages Microsoft Sway infrastructure to host fake pages, once again highlighting the abuse of legitimate cloud offerings for malicious purposes. "By using legitimate cloud applications, attackers provide credibility to victims, helping them to trust the content it serves," Netskope Threat Labs researcher Jan Michael Alcantara said . "Additionally, a victim uses their Microsoft 365 account that they're already logged-into when they open a Sway page, that can help persuade them about its legitimacy as well. Sway can also be shared through either a link (URL link or visual link) or embedded on a website using an iframe." The attacks have primarily singled out users in Asia and North America, with technology, manufacturing, and finance sectors being the most sought-after sectors. Microsoft Sway is a cloud-based tool for creating newsletters, presentations

Researchers Uncover Flaws in Windows Smart App Control and SmartScreen

Aug 05, 2024 Threat Intelligence / Vulnerability
Cybersecurity researchers have uncovered design weaknesses in Microsoft's Windows Smart App Control and SmartScreen that could enable threat actors to gain initial access to target environments without raising any warnings. Smart App Control ( SAC ) is a cloud-powered security feature introduced by Microsoft in Windows 11 to block malicious, untrusted, and potentially unwanted apps from being run on the system. In cases where the service is unable to make a prediction about the app, it checks if it's signed or has a valid signature so as to be executed. SmartScreen, which was released alongside Windows 10, is a similar security feature that determines whether a site or a downloaded app is potentially malicious. It also leverages a reputation-based approach for URL and app protection. "Microsoft Defender SmartScreen evaluates a website's URLs to determine if they're known to distribute or host unsafe content," Redmond notes in its documentation. "I
