arashitranslationAttention to “Ransom” Virus
During cyber attack in order not get infected by virus
what measures should be taken.
Ransomware which requests ransom.
In fact damage caused by this method is rapidly increasing in Japan.
In Japan personal computers detected with randomware
in 2015 there were around 6,700
in 2016 there were around 65,400, there is a nearly 10 times of increase.
Furthermore the target is not only personal computer
As shown in the visual here the attack also extends to smartphone.
It is said that the photos and videos cannot be opened.
In fact, the Information-technology Promotion Agency announced in January 2017
among “10 Major Security Threats”
damage caused by randomware requesting ransom
is at second place after “Unauthorized use of information such as credit card information”.
In other words, it is an anticipated threat.
As for the mechanism of infection,
I shall introduce a specific method using mail.
For instance the mail here.
The sender is a corporate in actual existence
the subject line of the mail writes “An invoice is sent through”.
While there is an attachment that looks like an invoice
in fact when you open it the device will be infected with the virus.
Next would be here, a mail from a major delivery service.
“In order to confirm the delivery address please click this URL”
is written in the mail.
Thinking that he may have forgotten such order, one unintentionally clicks the URL
the device will also be infected.
One more case,
in the mail here it is said that the sender is a famous corporate
but the mail address is free mail which anyone can obtain.
This may also cause infection if one opens the attachment.
Tokyo Metropolitan Police Department’s Crime Prevention Task Force mentioned about “Rurubu Travel” today
spam mails requesting confirmation of fake accommodation reservation appear
attention is called upon.
Opening the PDF attachment may cause infection by virus
there is such danger.
Then in order not to be affected what should be done.
According to the National Police Agency
please do not carelessly click the attachment or link.
Window version and antivirus software
should be kept up-to-date all the time.
Important files should be backed up in advance
such preservation task is said to be important.
In case your device get infected…
When the ransomware requests for ransom
please never pay ransom.
Even ransom is paid there is no guarantee that the criminal will decrypt the files.
In office etc in order not to spread the infection to other personal computers
please turn off the power.
The restore the computer you may format it
then put back the back up files.
The National Police Agency states that, in case you notice a damage
please consult the police.
