Google's cybersecurity teams, including Mandiant and the Google Threat Intelligence Group, have reported a new extortion email scam targeting companies in the USA. The group behind this campaign is identified as UNC3753, also known as 'Luna Moth' or 'Silent Ransom Group.' They employ social engineering tactics, such as voice phishing and benign invoice-themed emails, to gain unauthorized access to corporate networks. Once inside, they search for sensitive data and threaten to leak it unless a financial agreement is reached. The emails typically contain generic messages, claiming access to the victim's database and threatening severe consequences if the demands are ignored. The attackers promise to delete the data from their servers in exchange for payment, while also warning that failure to comply could lead to significant reputational damage, legal claims, and financial losses for the victim company. This scam highlights the increasing sophistication of cyber threats and the urgent need for businesses to strengthen their cybersecurity measures.
