"Agent Tesla Malware Spreading via Old MS Excel Vulnerability: Hackers at Work"

Hackers are exploiting an old vulnerability in Microsoft Office, specifically in Excel, to distribute the Agent Tesla malware. The attackers use phishing campaigns with decoy Excel documents attached to trick users into opening them, activating the exploitation of the vulnerability. Once the attachment is opened, the malware initiates communication with a malicious destination and downloads additional files without user interaction. The malware, Agent Tesla, is a keylogger and remote access trojan that harvests sensitive information from compromised hosts. This highlights the importance of organizations staying updated on evolving cyber threats.
