Resiliency must be priority as ransomware attacks increase - report

Organisations of all sizes are increasingly falling victim to ransomware attacks and inadequately protecting against this rising cyber threat.

According to new data in the Veeam 2023 Ransomware Trends Report, one in seven organisations will see almost all (>80%) data affected as a result of a ransomware attack pointing to a significant gap in protection. 

Veeam found that attackers almost always (93%+) target backups during cyber attacks and are successful in debilitating their victims ability to recover in 75% of those events, reinforcing the criticality of immutability and air gapping to ensure backup repositories are protected. 

The 2023 Ransomware Trends Report shares insights from 1,200 impacted organisations and nearly 3,000 cyber attacks. The survey examines key takeaways from these incidents, their impact on IT environments and the steps taken, or needed, to implement data protection strategies that ensure business resiliency.

This research report encompasses four different roles involved in cyber-preparedness and/or mitigation including, security professionals, CISOs or similar IT executives, IT Operations generalists, and backup administrators. 

Danny Allan, CTO at Veeam, comments, "The report shows that today it's not about IF your organisation will be the target of a cyber attack, but how often.

"Although security and prevention remain important, its critical that every organisation focuses on how rapidly they can recover by making their organisation more resilient.

"We need to focus on effective ransomware preparedness by focusing on the basics, including strong security measures and testing both original data and backups, ensuring survivability of the backup solutions, and ensuring alignment across the backup and cyber teams for a unified stance."

Paying the ransom does not ensure recoverability 

For the second year in a row, the majority (80%) of the organisations surveyed paid the ransom to end an attack and recover data now up 4% compared to the year prior despite 41% of organisations having a Do-Not-Pay policy on ransomware.

Still, while 59% paid the ransom and were able to recover data, 21% paid the ransom yet still didn't get their data back from the cyber criminals.

Additionally, the report found only 16% of organisations avoided paying ransom because they were able to recover from backups. The global statistic of organisations able to recover data themselves without paying ransom is down from 19% in last years survey. 

To avoid paying ransom, your backups must survive 

Following a ransomware attack, IT leaders have two choices: pay the ransom or restore-from-backup. As far as recovery goes, the research reveals that in almost all (93%) cyber-events, criminals attempt to attack the backup repositories, resulting in 75% losing at least some of their backup repositories during the attack, and more than one-third (39%) of backup repositories being completely lost. 

By attacking the backup solution, attackers remove the option of recovery and essentially force paying the ransom. While best practices such as securing backup credentials, automating cyber detection scans of backups, and auto verifying that backups are restorable are beneficial to protect against attacks, the key tactic is to ensure that the backup repositories cannot be deleted or corrupted, Veeam states.

To do so, organisations must focus on immutability. The good news is that based on lessons learned from those who had been victims 82% use immutable clouds, 64% use immutable disks, and only 2% of organisations do not have immutability in at least one tier of their backup solution. 

Do not re-infect during recovery 

When respondents were asked how they ensure that data is clean during restoration, 44% of respondents complete some form of isolated-staging to re-scan data from backup repositories prior to reintroduction into the production environment.

Unfortunately, that means that the majority (56%) of organisations run the risk of re-infecting the production environment by not having a means to ensure clean data during recovery. This is why it is important to thoroughly scan data during the recovery process, according to Veeam.

Other key findings from the Veeam 2023 Ransomware Trends Report include: 

• Cyber-insurance is becoming too expensive: 21% of organisations stated that ransomware is now specifically excluded from their policies, and those with cyber insurance saw changes in their last policy renewals: 74% saw increased premiums, 43% saw increased deductibles, 10% saw coverage benefits reduced. 
• Incident response playbooks depend on backup: 87% of organisations have a risk management program that drives their security roadmap, yet only 35% believe their program is working well, while 52% are seeking to improve their situation, and 13% do not yet have an established program. Findings reveal the most common elements of the playbook in preparation against a cyberattack are clean backup copies and recurring verification that the backups are recoverable. 
• Organisational alignment continues to suffer: While many organisations may deem ransomware to be a disaster and therefore include cyberattacks within their Business Continuity or Disaster Recovery (BC/DR) planning, 60% of organisations say they still need significant improvement or complete overhauls between their backup and cyber teams to be prepared for this scenario.
