Security researchers are warning users about the increase in a particular phishing technique that tricks unsuspecting employees into performing malicious activities. This can include installing malware, transferring money or handing over their login credentials.
What’s new about the phishing technique?
What is the success rate of such attacks?
According to new research from Barracuda Networks, analysis of 500,000 emails show that conversation hijacking attacks have risen by over 400% between July and November last year.
“These attacks are highly personalized, including the content, and therefore a lot more effective. They have the potential of a very large payout, especially when organizations are preparing to make a large payment, purchase or an acquisition,” Olesia Klevchuk, senior product manager for email security at Barracuda Networks, told ZDNet.
How to combat the risk?
Conversation-hijacking attacks are more sophisticated than regular phishing attacks. Hence they are impossible to spot. Therefore, users should pay attention to the email address thread to understand whether a message is suspicious or not.
Users should also be wary of sudden demands for payments or transfers and if there’s a doubt about the origin of the request, they should contact the person requesting it.
