An ever-evolving and rampant form of cybercrime that targets emails as the potential medium to conduct fraud is known as Business Email Compromise. Targeting commercial, government as well as non-profit organizations, BEC can lead to huge amounts of data loss, security breach, and compromised financial assets. It is a common misconception that cybercriminals usually lay their focus on MNCs and enterprise-level organizations. SMEs these days are just as much a target to email fraud as the larger industry players. How Can BEC Affect Organizations?  Examples of BEC include sophisticated social engineering attacks like phishing, CEO fraud, fake invoices, and email spoofing, to name a few. It can also be termed an impersonation attack wherein an attacker aims to defraud a company by posing people in authoritarian positions. Impersonating people like the CFO or CEO, a business partner, or anyone you will blindly place your trust in is what drives these attacks' success. February of...

In 1982, when SMTP was first specified, it did not contain any mechanism for providing security at the transport level to secure communications between mail transfer agents. Later, in 1999, the STARTTLS command was added to SMTP that in turn supported the encryption of emails in between the servers, providing the ability to convert a non-secure connection into a secure one that is encrypted using TLS protocol. However, encryption is optional in SMTP, which implies that emails can be sent in plaintext.  Mail Transfer Agent-Strict Transport Security (MTA-STS)  is a relatively new standard that enables mail service providers the ability to enforce Transport Layer Security (TLS) to secure SMTP connections and to specify whether the sending SMTP servers should refuse to deliver emails to MX hosts that that does not offer TLS with a reliable server certificate. It has been proven to successfully mitigate TLS downgrade attacks and Man-in-the-Middle (MitM) attacks. SMTP TLS Report...

Vulnerability Management (VM) has long been a cornerstone of organizational cybersecurity. Nearly as old as the discipline of cybersecurity itself, it aims to help organizations identify and address potential security issues before they become serious problems. Yet, in recent years, the limitations of this approach have become increasingly evident.  At its core, Vulnerability Management processes remain essential for identifying and addressing weaknesses. But as time marches on and attack avenues evolve, this approach is beginning to show its age. In a recent report, How to Grow Vulnerability Management into Exposure Management (Gartner, How to Grow Vulnerability Management Into Exposure Management, 8 November 2024, Mitchell Schneider Et Al.), we believe Gartner® addresses this point precisely and demonstrates how organizations can – and must – shift from a vulnerability-centric strategy to a broader Exposure Management (EM) framework. We feel it's more than a worthwhile read an...
