Defend Against Ransomware

Sponsored Content provided by Marty Cayton - President & Owner, TeamLogic IT of Wilmington & Fayetteville

Ransomware is malicious software that blocks access to your data and threatens to publish or delete it until you pay a ransom. Simple ransomware can make your system inaccessible in such a way that an experienced IT security person can often reverse the effects.

Recently, we have seen the rise of more sophisticated malware that encrypts files and demands a ransom payment to decrypt them in difficult-to0trace digital currencies, such as Bitcoin. 


Recent Attacks

The ransomware attack Petwrap first occurred in December 2016 as a variant of the GoldenEye malware. While this specific ransomware started in Europe, it has quickly spread to the United States and requests a ransom equivalent to $300 (USD) in Bitcoin.
 
The Petya component of Petwrap allows the malware to remain viable on infected systems and attack the master boot record, while the EternalBlue component allows it to proliferate through a business. This malicious software is particularly aggressive and can spread rapidly throughout an organization, crippling the business.
 
As your managed IT service provider, TeamLogic is committed to helping your business stay secure.


Impacts

Ransomware can cost a lot more than the requested ransom in terms of business disruption, downtime and recovery, unavailable data, inoperable devices and damaged reputation.


Safeguards

In addition to the security practices outlined in Protect Yourself With Basic Network Security Practices, ensure you have the following safeguards and employee education training in place:
 
  • Increase the frequency of complete system backups and always follow data back-up best practices to avoid paying ransoms, and to ensure you can recover using your backed-up data.
  • Check system and network email security protocols more often than in the past, as no one knows the day or hour an attack will take place.
  • Consider restricting peer-to-peer file sharing – a common way infections spread - on your network.
  • Include ransomware in general planning for data breaches and add specifics for incident response.
  • Decide in advance if, and how, your firm would pay ransom.


Employee Education

Ransomware attacks are typically carried out using a Trojan, which is a legitimate-looking file users are tricked into downloading or opening when it arrives as an email attachment.
 
A good defense strategy is to launch a Ransomware Employee Education Program that:
  • Identifies suspicious email, which is often the main channel for attacks.
  • Provides samples of ransom popups.
  • Shows warning signs, such as missing file extensions or extensions such as “.crypted” or “.cryptor”.
  • Directs employees not to "trust" a web page, access Facebook, or use messaging applications, such as WhatsApp, from a business device.
  • Trains users to be aware of fraudulent e-mail messages that use names similar to popular services - for example, "PayePal" (instead of PayPal) or “LinkedEn” (instead of LinkedIn) - or use popular service names without commas or excessive characters.
  • Teaches that when a PC is attacked, employees should disconnect from the internet, turn the computer off and notify the IT Backup Team.
If you find yourself the victim of a ransomware attack, do not pay the ransom. Call TeamLogic IT first, as there is often no evidence that hackers give files back even after a ransom is paid. As your technology advisor, TeamLogic IT is always available to discuss any concerns you have around your network security and computing environment.
