Do Not Open This PDF On A Microsoft Windows PC

Microsoft has warned about the increasing use of PDF attachments in cyberattacks, particularly during the U.S. tax season. Attackers have been using PDFs with embedded links that redirect users to counterfeit pages, such as a fake DocuSign site. TrustWave SpiderLabs has identified a new campaign involving a fake payment SWIFT copy that leads to a malicious PDF containing obfuscated JavaScript, which downloads a script that conceals the RemcosRAT payload using steganography. This technique involves hiding links within images, making them difficult to detect. The latest attacks begin with phishing emails containing malicious PDFs that direct victims to harmful webpages, facilitating the delivery of RemcosRAT, a trojan that allows remote control of compromised systems. Users are advised to be cautious of emails labeled “SWIFT Copy” and to delete suspicious emails immediately.

Pentagon issued Signal warning before Trump war group chat leak: Report

Pentagon officials issued a warning about the Signal messaging application after The Atlantic Editor-in-Chief Jeffrey Goldberg was inadvertently included in a group chat with high-ranking Trump administration officials discussing sensitive military strategies, including potential airstrikes in Yemen. An email disclosed a "vulnerability" in Signal, stating that the app is a target for Russian hacking groups that exploit its "linked devices" feature to monitor conversations. The email advised against using Signal for storing nonpublic unclassified information, although it can be used for "unclassified accountability/recall exercises." President Trump and Senators Mark Warner and Angus King commented on the situation, with concerns raised about the potential risks to national security. The administration is reviewing the incident, but no officials have indicated plans to resign.

This dangerous new Windows malware hides from your antivirus while impersonating a popular PC brand

A new strain of malware called CoffeeLoader targets Windows users by pretending to be an ASUS utility, specifically imitating ASUS's Armoury Crate. It has sophisticated evasion techniques that allow it to bypass antivirus software. Once installed, it deploys infostealers like Rhadamanthys Infostealer to extract sensitive information. CoffeeLoader operates undetected by executing code on the GPU instead of the CPU, using Call Stack Spoofing to disguise its activities, and employing Sleep Obfuscation to encrypt itself in memory when inactive. It also exploits Windows Fibers to evade detection. To protect against CoffeeLoader, users should download Armoury Crate only from the official ASUS website and be cautious of deceptive links and ads that may lead to malware installation.

Malicious Android Apps Hide in Plain Sight, Target Millions of Devices

A malicious Android app campaign called “Vapor” has been discovered, designed to trick users into revealing sensitive information through misleading ads. This campaign includes various apps posing as utilities, such as QR code scanners and health trackers, with over 60 million downloads collectively. It primarily targets users in Brazil, the United States, and Mexico. Some apps have evaded detection by not showing harmful behavior immediately after installation and by disguising themselves. They use tactics like inundating users with full-screen ads and employing scare tactics to prompt downloads of additional harmful apps. The campaign may be run by a single cybercriminal group or a coalition, utilizing shared malware development tools. Despite Google removing many harmful apps, new variants continue to emerge, highlighting the evolving nature of mobile malware.

Get Rid of These 12 Android Apps That Secretly Record Your Conversations

Security researchers have identified malicious Android applications that invade user privacy by recording audio, intercepting messages, and stealing sensitive data without user consent. A cybersecurity firm, ESET, uncovered a cyber espionage operation that infiltrated Android devices through the Google Play Store and alternative app sources, initially involving six apps on the Play Store with over 1,400 downloads each before their removal. These deceptive apps, which masquerade as messaging services, embed malware capable of tracking user locations and harvesting personal information. Hackers employ tactics like “romance baiting” to trick users into downloading infected apps, such as those containing VajraSpy malware. Experts categorize these malicious apps into three groups: fake messaging apps that steal data, apps exploiting Android’s accessibility features, and a fake news app that harvests user data. A list of twelve flagged apps includes Rafaqat, Privee Talk, MeetMe, Let’s Chat, Quick Chat, Chit Chat, YohooTalk, TikTalk, Hello Chat, Nidus, GlowChat, and Wave Chat, which should be removed immediately. To protect against spyware apps, users are advised to uninstall suspicious apps, change passwords, enable two-factor authentication, run security scans, and stay informed about cybersecurity updates. Caution is recommended when downloading apps, including verifying developers, checking reviews, and avoiding third-party app stores.

Nation-state groups hit hundreds of organizations with Microsoft Windows zero-day

Trend Micro has identified a zero-day vulnerability in Microsoft Windows, tracked as ZDI-CAN-25373, which allows attackers to execute hidden malicious commands through .lnk files. This vulnerability has been exploited since 2017, primarily by state-sponsored groups, affecting at least 300 organizations and thousands of devices. North Korean groups APT43 and APT37 are mainly responsible for these exploits, with nearly half of the attacks linked to them. Other state-backed groups from Iran, Russia, and China account for about 20% of the attacks. Microsoft has advised users to be cautious with files from unverified sources but does not classify the issue as severe enough for immediate action. Trend Micro's research shows that attackers disguise malicious .lnk files as different file types, using hidden command line arguments. Microsoft acknowledges the research but downplays the implications, while experts suggest that addressing the vulnerability may require significant changes to .lnk file functionality.
