The U.S. Federal Bureau of Investigation (FBI) has warned of social engineering attacks mounted by a criminal extortion actor known as Luna Moth targeting law firms over the past two years. The campaign leverages "information technology (IT) themed social engineering calls, and callback phishing emails, to gain remote access to systems or devices and steal sensitive data to extort the victims," the FBI said in an advisory. Luna Moth, also called Chatty Spider, Silent Ransom Group (SRG), Storm-0252, and UNC3753, is known to be active since at least 2022 , primarily employing a tactic called callback phishing or telephone-oriented attack delivery (TOAD) to trick unsuspecting users into calling phone numbers listed in benign-looking phishing emails related to invoices and subscription payments. It's worth mentioning here that Luna Moth refers to the same hacking crew that previously carried out BazarCall (aka BazaCall) campaigns to deploy ransomware like Conti . The ...

PCI DSS 4.0 encourages the implementation of anti-phishing controls like DMARC! This highlights and reinforces the importance of preventative measures against email fraud, domain spoofing, and phishing in the financial space. While not a mandate or a requirement for PCI DSS compliance, DMARC and supporting email authentication technologies like SPF and DKIM play a pivotal role in protecting domain names against misuse.  Organizations can sign up for a DMARC analyzer trial to simplify their DMARC implementation, without the need for technical expertise. With more than 94% of organizations falling victim to phishing, this is the cue for businesses of all sizes to strengthen domain security and prevent the next big cyber attack. Many organizations turn to email authentication management solutions like PowerDMARC to simplify implementation, monitor authentication, and ensure continuous protection. On the flip side, it also presents a golden opportunity for MSPs to sell DMARC to th...

A new exploitation technique called Simple Mail Transfer Protocol ( SMTP ) smuggling can be weaponized by threat actors to send spoofed emails with fake sender addresses while bypassing security measures. "Threat actors could abuse vulnerable SMTP servers worldwide to send malicious emails from arbitrary email addresses, allowing targeted phishing attacks," Timo Longin, a senior security consultant at SEC Consult,  said  in an analysis published last month. SMTP is a TCP/IP protocol used to send and receive email messages over a network. To relay a message from an email client (aka mail user agent), an SMTP connection is established between the client and server in order to transmit the actual content of the email. The server then relies on what's called a mail transfer agent (MTA) to check the domain of the recipient's email address, and if it's different from that of the sender, it queries the domain name system (DNS) to look up the  MX (mail exchanger) rec...
