Cyber criminals have increased spamming with malware-laced emails. Malicious servers are spewing out malicious emails at the rate of hundreds of millions of emails per day. Cyber experts state that the spam volume has reached never before levels. When more spam emails are sent, the chances of hits are better, and considering the reports received, cyber criminals are achieving what they desire – malware infection has considerably increased.
And it is not just any ordinary malware that is currently being spread – it is the “Locky” ransomware – and it is considered to be the top most malware doing the rounds these days. Cyber security analysts monitoring the prevalence of malware have reported that the Locky is spreading very rapidly and is successfully infecting scores of devices and computers.
Cyber security experts also warn that the phishing and spear-phishing emails have also become sophisticated – they look pretty legitimate which would convince nearly any user that the email is authentic and the attachment could be opened safely.
In the second quarter of 2016, the Necurs botnet, the Nuclear exploit kit and the Angles exploit kit shut down which led to a decrease in spam emails and infections. However, the Necurs came back with more vigour and sophistication that cyber security experts feel could have more drastic consequences.
The Necurs botnet had pushed Locky to the No.1 position in infections even before it shut down for the brief period. But, the Necurs botnet has come back and is spewing massive spam that is promising more infections – be ready to face significant system downtime and loss of data.
Locky targets Android OS
Nowadays, cyber criminals are targeting mobile devices running on the Android operating system. More malware is being discovered against the Android operating system than against the iOS.
Stay protected against Ransomware
In order to stay protected from ransomware, users have to be careful when opening any attachments from doubtful sources. And regular and systematic backups of data have to be performed. Nevertheless, a robust antivirus that proactively protects against zero-day exploits and removes malware by using default-deny technology, auto-sandboxing , spam filtering and real-time file scanning is essential for any enterprise and also for users.
