Imagine using your trusty computer while beating a deadline, and suddenly your files become inaccessible. Thereafter, you receive an anonymous email saying you have to deposit money or your files are gone for good. You google the situation and find that you’ve just been hit by hacker- more specifically, by a ransomware.

Now what on earth is a ransomware?

Ransomware is a variation of malware (malicious software) that encrypts files and documents. It can infect a single unit of computer or even an entire network- including servers. From the word itself, the perpetrator demands a ransom from the victim in exchange for a “decryption key” to regain access.

Another method is “malspam” or malicious spam which usually pops up in your email. In most cases these malspam emails comes with malware-laced attachments, enticing graphics, and too-good-to-be-true promos that infects your system once interacted with.

Ransomware attacks can gravely injure your economic stability- especially if you are an organization.

But this does not mean that non-networked computers are safe. In fact, it was reported that in the first ten months of the 2020 pandemic, the significant 75% increase in Singapore’s ransomware attack incidents are attributed to work-from-home set-ups. Regardless, the damage done is ludicrous. A study of CrowdStrike reveals that out of 46% of firms hit, more than 28% chose to pay the ransom, costing them an average of $1.47 Million USD!

  • Isolate the infected computer units
  • Notify your IT security team, if you have one. Otherwise, contact an IT service
  • Identify the type of malware by backtracking your computer log/activities
  • Inform your employees of the attack to mitigate the possibility of heavier damage
  • Change your login credentials
  • Take a photo of the ransom note
  • Notify the authorities and present your evidence: your computer log/activities and the ransom note

Finally, you need to raise awareness on your organization; what a ransomware is, how it works, and how to always be on the lookout for suspicious malvertisements, malspams, and online shop plugins.

5. Do I have to pay the “ransom”?

In the event that you have been infected, paying for the decryption key is highly discouraged. It does not guarantee that your filed will be returned at once. Instead, you should disconnect the infected unit from
your network immediately. This should prevent the spread and will work like a ransomware kill switch. To reiterate, use an updated anti-virus software or an antimalware program, if you have any, before initiating data restoration from your backup.
