Additionally, a pig-butchering scam resulted in a $73.6 million fraud, with the perpetrator sentenced to 20 years in prison. The report also highlights the rise of various malware, including LTX Stealer and Marco Stealer, which target sensitive data across multiple platforms.”, “insight”: “

The ThreatsDay Bulletin for February 12, 2026, outlines significant cybersecurity threats, including a critical vulnerability in Microsoft Notepad (CVE-2026-20841) that allows remote code execution through command injection. This flaw could enable attackers to execute arbitrary code by tricking users into clicking malicious links in Markdown files. Microsoft patched this vulnerability, which has a CVSS score of 8.8, as part of its monthly updates.

Another highlight is the sentencing of Daren Li, who was involved in a pig-butchering scam that defrauded victims of over $73.6 million. Li, who fled after cutting off his ankle monitor, was sentenced to 20 years in prison for his role in this international cryptocurrency investment scheme.

The bulletin also reports on the emergence of various new malware threats, such as LTX Stealer, which targets Windows systems for credential harvesting, and Marco Stealer, which focuses on stealing sensitive files from cloud services. These threats underscore the evolving tactics used by cybercriminals.
