Visibility is key for #security in M&A - However, deals are often fast-moving, making due diligence difficult

"It's a big shift in the way you build systems and you know there's no perfect answer here. The best you can really do is have multiple people look at something in those situations because at the end of the day you are trusting people."

A threat actor targeted the legal/retail sectors in callback phishing attacks that cost victims thousands:

-Callback phishing attack requires significant investment, including setting up fake call centers/ unique infrastructure
-But the lack of malware in the original phishing email/ the abuse of legitimate tools make the attack harder to detect

“By design, this style of social engineering attack leaves very few artifacts because of the use of legit trusted tech tools to carry out attacks."
