LinkedIn Phishing Campaign Delivers RAT via DLL Sideloading—2026 Incident Analysis

In January 2026, security researchers identified a sophisticated phishing campaign exploiting LinkedIn direct messages to deliver weaponized WinRAR self-extracting archives targeting high-value individuals. Attackers used social engineering to establish trust, convincing victims to download an archive containing a legitimate open-source PDF reader, a malicious DLL, the Python interpreter, and a decoy file. Upon execution, the PDF reader sideloaded the malicious DLL, which deployed the Python interpreter, created persistence via a Registry Run key, and executed Base64-encoded shellcode in memory. This led to covert remote access, data exfiltration, and enabled attackers to move laterally across networks. The incident underscores a broader trend of attackers abusing social media platforms for initial access, bypassing traditional email-centric defenses, and leveraging open-source tools with advanced evasion techniques like DLL sideloading. As social engineering campaigns diversify across communication channels, all business sectors face amplified risks of stealthy malware delivery and long-term compromise.

Information Technology/IT9 months ago

Pax8’s 2026 MSP Partner Data Exposure: Lessons from a Cloud Email Mishap

In January 2026, cloud marketplace giant Pax8 disclosed that it inadvertently exposed sensitive business information related to approximately 1,800 managed service provider (MSP) partners. The incident occurred when a Pax8 EMEA account manager mistakenly emailed a spreadsheet—intended for internal use—to under 40 UK-based partners. The file contained details such as partner and customer organization IDs, Microsoft product SKUs, license counts, renewal dates, booking data, and internal pricing. While the leaked data reportedly did not include personally identifiable information, it revealed confidential customer portfolios and licensing metrics, with over 56,000 entries potentially providing valuable intelligence to competitors or cybercriminals. Pax8 moved quickly to recall the emails, directly requested deletion, and launched an internal review to address the flaw. This breach highlights the persistent risks linked to accidental data disclosures, especially within cloud ecosystems and partner networks. Data leaks through misdirected emails are increasingly exploited by threat actors for social engineering, competitive maneuvering, and phased cyberattacks, driving renewed urgency for zero trust controls and robust data-handling processes.
