Phishing Tops 2023’s Most Common Cyber Attack Initial Access Method

Phishing Tops 2023's Most Common Cyber AttackNew analysis shows that the combination of phishing, email, remote access, and compromised accounts are the focus for most threat actors.

Data across the industry corroborates new findings in cyber risk advisory and response firm Kroll’s just-released Q4 2023 Cyber Threat Landscape Report. But what’s interesting in this report is how the data tells a story of where organizations are falling short in their preventative efforts.

First, let’s jump into the findings of where each of the common initial access methods rank. As shown below, while phishing decreased between 2022 and 2023, it still dominates as the most-used method.

Interesting to note is the massive jump in the use of Valid Accounts whereby initial access brokers compromise accounts and sell them to threat actors who leverage the accounts as a means of gaining access to an organization. Since we all know how most of those valid accounts were obtained, I’m going to point out that phishing is an even bigger problem.

If we “zoom out” a bit and look at the most common incident threat types, we see ransomware taking a back seat last year to email compromise – again, likely using credential harvesting to obtain credentials.

The underlying story here is clear – phishing is the problem. Whether we’re talking about phishing with the intent of compromising credentials to be used later, or phishing used to infect systems and gain access, cybercriminals are leveraging phishing more now than ever. 

Your layered defense against these attacks must include a vigilant user; one who has undergone continual security awareness training, who knows what to look for and how to spot a suspicious email.
