Recent cybersecurity investigations have uncovered several sophisticated attack vectors threatening organizations worldwide. Here’s an analysis of the most significant current threats:
Zero-day Attack Using Corrupted Files
– Attackers are utilizing corrupted Word documents and ZIP archives to bypass security systems
– Files show zero detections on VirusTotal
– When opened with native applications, files self-restore and release malicious content
– ANY.RUN sandbox successfully detects and analyzes these threats through interactive cloud VM
Fileless Malware Campaign
– New attack utilizing Psloramyra loader to distribute Quasar RAT
– Employs LoLBaS technique with PowerShell scripts
– Operates entirely in system memory, leaving no disk traces
– Maintains persistence through scheduled tasks running every two minutes
Azure Blob Storage Exploitation
– Phishing campaigns hosted on Azure cloud storage
– Utilizes *.blob[.]core[.]windows[.]net subdomain
– Collects victim’s system information to appear legitimate
– Targets user credentials through fake login forms
Emmenhtal Loader Operations
– Multi-stage attack chain using various scripts
– Process includes:
– LNK file initialization
– PowerShell execution
– AES encryption/decryption
– Delivers various malware including Lumma, Amadey, and others
These emerging threats demonstrate the evolving sophistication of cyber attacks, emphasizing the importance of advanced security measures and continuous monitoring.
