Top Highlights A new malware campaign, SORVEPOTEL, targets Brazilian WhatsApp users, spreading via phishing emails and malicious ZIP files, primarily aiming at enterprises rather than consumers. Upon opening a malicious attachment, it silently executes a PowerShell script that downloads and installs additional payloads, establishing persistence on Windows systems. The malware propagates automatically through WhatsApp Web, sending spam to contacts and groups, leading to account bans without data theft or ransomware activity. The campaign exemplifies how cybercriminals exploit popular messaging platforms for rapid, large-scale malware spread with minimal user engagement. What’s the Problem? The story reports that in Brazil, a new…
USB Devices: Hidden Cybersecurity Threats to Critical Systems and How to Protect Against Them
Quick Takeaways NIST’s guide emphasizes implementing procedural, physical, and technical controls to securely manage the use of portable storage devices like USBs in industrial control systems, minimizing cybersecurity risks. Organizations should enforce strict policies on device procurement, authorization, and sanitization, including asset management, access control, logging, and staff training. Physical controls include secure storage and labeling of devices, while technical controls involve malware scanning, encryption, disabling unnecessary ports, and restricting device functions to prevent malware spread. Transportation and sanitization procedures, such as encryption during transit and thorough device sanitization before disposal, are critical to reducing risks associated with portable media…
