Stop Ransomware with Email Security
We are the weak link.
Hackers still exploiting the human factor to carry out ransomware attacks
Nearly 70 percent of successful ransomware attacks in 2017 were the result of hackers gaining access to enterprise networks by phishing via email or social media network. Around half of such attacks also took place due to the carelessness of employees and in some cases, employees paid ransom to hackers without the sanction of IT security departments.
New research by security firm SentinelOne has revealed several underlying causes behind a spurt in ransomware attacks on enterprises based in the UK. While known factors such as failure of anti-virus software to detect new malware, poor response to ransomware attacks, and lack of ability to decrypt encrypted files have continued to plague enterprises, the human factor continues to be the single largest factor behind the continuance of ransomware attacks on the UK's industries.
A survey of decision makers from IT and risk, fraud and compliance departments at various enterprises in the UK revealed that of those organisations who suffered ransomware attacks in the last 12 months, 69 percent were a result of hackers gaining access to enterprise networks by phishing via email or social media network.
While 44 percent of the decision makers said that ransomware attacks on their organisations took place due to employees clicking on compromised websites, 51 percent said that such attacks took place due to employee carelessness.
