A report released today by PhishMe indicated employees can dramatically improve their ability to detect phishing emails with a little practice. The study, titled “Enterprise Phishing Susceptibility Analysis,” was based on the results of 8 million phishing simulations done by the company over a 13-month span. In total, 75 percent of the organizations were training more than 1,000 employees. They were largely located in the U.S. and were distributed across 23 industries.

Security Awareness Decreases Click Rates

The report showed that the average response rate to phishing emails is about 20 percent. However, employees who click on one phishing email are 67 percent more likely than average to click on another one; they have a click rate of 35 percent.

Across all companies, messages pretending to be regular office communications tend to hit the hardest, with a 22 percent click-through rate. Those alleged interoffice emails that claim to have “your scanned file” are even more effective, with a 36 percent open rate, according to PhishMe.

CSO Online noted that phishing may increase during the holidays. Common seasonal phishing emails include holiday e-cards, holiday sales and discount offers, travel notifications and package delivery notifications. Charity fraud is also a common endeavor for phishing cybercriminals.

However, the study did find that the click rate fell to 13 percent if employees went through just three simulation exercises; it dropped even lower — to 4 percent — after the fourth. After the fifth training exercise, the success rate of those phishing emails fell to 0.2 percent.

Warning Against Phishing Emails

The study asked whether phishing training works, and the results seem to support the notion that it does. From the analysis, PhishMe was able to develop views of reduction in scenario response rates, decreases in repeat offenses and increases in user reporting of suspicious emails, all of which help protect corporate information and prevent potential threats from becoming realized.

To ensure employees weren’t simply learning to avoid the simulated phishing emails, PhishMe created over 300 phishing templates based on actual phishing emails seen in the wild. Cybercriminals will likely be using the same diverse array of tactics to target users, further underscoring the effectiveness of security awareness programs and training.

This is just the latest in a line of research showing that training is an effective way to mitigate the effects of phishing. Such training may not only reduce the financial costs of phishing, but also limit the productivity hit that organizations experience due to the malicious emails and the damage control that follows.

IBM identifies zero-day vulnerability in Zyxel NAS devices

12 min read - While investigating CVE-2023-27992, a vulnerability affecting Zyxel network-attached storage (NAS) devices, the IBM X-Force uncovered two new flaws, which when used together, allow for pre-authenticated remote code execution. Zyxel NAS devices are typically used by consumers as cloud storage devices for homes or small to medium-sized businesses. When used together, the flaws X-Force discovered allow a remote attacker to execute arbitrary code on the device with superuser permissions and without requiring any credentials. This results in complete control over the…

What cybersecurity pros can learn from first responders
