New Malware Hidden In Emails About Flu Protection
Fear is a fantastic way to spread malware, which is why hackers around the world are using the fear of a flu pandemic as a hook to install a nasty strain of ransomware.
Researchers at MyOnlineSecurity have detected a cunning email campaign which spoofs the Centers for Disease Control and bears headlines warning of a Flu Pandemic.
The message is short and to the point, explaining that a flu pandemic has been detected and urges recipients to read the attached document for further instructions to protect their families and help keep it from spreading. The instructions also helpfully include the note that in order to view the document properly you'll need to click the 'Enable Editing' button.
The attachment bears the name "Flu Pandemic Warning," which reinforces the message itself. It's an excellent choice from the perspective of the hackers, because they know that a relatively high percentage of those who receive this message from what appears to be a trusted agency will open it.
Unfortunately, the moment they open the file and click to enable editing, they doom themselves. The word document is poisoned and contains scripts that will install the GrandCrab v5.2 ransomware on the victim's machine, which will promptly lock their files and demand a hefty payment.
While this is a nasty and especially effective campaign, it's not the only one that the creators of Grand Crab are engaged in. Recently, the Chinese government issued their own alert, stating that beginning on March 11, various government departments were bombarded with phishing-style emails intent on installing ransomware on their servers.
All that to say, vigilance is more important now than ever. There's no telling how long this campaign will run, or what may come after it, but one thing you can be sure of. They're not going to stop.
