Ransomware attack: Recovery after falling victim

hacker-smallPaying unlikely to be an option as cybercriminals refine strategy

Ransomware is a form of cybercrime that has been around for a number of years; however, the threat level is increasing and there are signs that the cybercriminals’ strategy is becoming more refined.

In year-on-year figures for 2014-15 and 2015-16 from IT security experts Kaspersky, crypto ransomware attacks, which locks up data and renders it inaccessible without the cryptographic key, were shown to have increased more than five-fold. Data analysis also show the rate at which UK companies are falling victim is almost 20% higher than the global average.

This indicates UK businesses are either being more closely targeted by internet criminal gangs or have insufficient IT security capability. Whatever, the reason, UK companies face a greater likelihood of falling victim to an attack. Consequently, it is essential your company has the capability to recover from a ransomware attack without having to pay cybercriminals to provide the cryptographic key to unlock the data.

Recovery from a ransomware attack

Although prevention is better than cure, prevention doesn’t always work, especially when it comes to defending criminal enterprise. Having the right prevention countermeasures in place is essential because the disruption to business following an attack may be severe.

To be clear, Paralogic doesn’t endorse paying ransomware demands. However, many have opted to pay cybercriminal ransom demands, especially when the sum in question doesn’t break the bank and can be explained away as incidental minor expenses without a cost centre. However, criminals are now being more targeted in their approach and demanding larger amounts. It may be impossible to pay without damaging company finances and/or being able to lose it on the P&L.

Clearly, the best policy is to be in a position to refuse to pay and then invoke a Disaster Recovery (DR) and Business Continuity (BC) plan.

How to be in a position to recover from a ransomware attack

The ransomware attack renders data and systems unusable because it cryptographically encodes data. It is unfeasible to crack the codes and the only way to return to normal business operations with as little damage as possible is to restore systems and data from backups quickly.

Designing a backup scheme and choosing an appropriate solution for executing your DR and BC plan means you need to understand:

  • Recovery Point Objective (RPO)
    • How much work (or changed data) you can afford to lose
  • Recovery Time Objective (RTO)
    • How long you can tolerate systems and data being offline
