Businesses are losing the battle when it comes to defending against ransomware attacks, according to a Veeam report, which found that 72% of organizations had partial or complete attacks on their backup repositories, dramatically impacting the ability to recover data without paying the ransom.
80% of successful attacks targeted known vulnerabilities — reinforcing the importance of patching and upgrading software. Almost all attackers attempted to destroy backup repositories to disable the victim’s ability to recover without paying the ransom.
The report reveals the results of an independent research firm that surveyed 1,000 IT leaders whose organizations had been successfully attacked by ransomware at least once during the past 12 months.
“Ransomware has democratized data theft and requires a collaborative doubling down from organizations across every industry to maximize their ability to remediate and recover without paying the ransom,” said Danny Allan, CTO at Veeam. “Paying cybercriminals to restore data is not a data protection strategy. There is no guarantee of recovering data, the risks of reputational damage and loss of customer confidence are high, and most importantly, this feeds a self-fulfilling prophecy that rewards criminal activity.”
Paying the ransom doesn’t guarantee data recovery
Of the organizations surveyed, 76% of cyber-victims paid the ransom to end an attack and recover data. Unfortunately, while 52% paid the ransom and were able to recover data, 24% paid the ransom but were still not able to recover data — resulting in a one out of three chance that paying the ransom still leads to no data. It is notable that 19% of organizations did not pay the ransom because they were able to recover their own data. This is what the remaining 81% of cyber-victims must aspire to — recovering data without paying the ransom.
“One of the hallmarks of a strong Modern Data Protection strategy is a commitment to a clear policy that the organization will never pay the ransom, but do everything in its power to prevent, remediate and recover from attacks,” added Allan.
“Despite the pervasive and inevitable threat of ransomware, the narrative that businesses are helpless in the face of it is not an accurate one. Educate employees and ensure they practice impeccable digital hygiene; regularly conduct rigorous tests of your data protection solutions and protocols; and create detailed business continuity plans that prepare key stakeholders for worst-case scenarios.”
Prevention requires diligence from both IT and users
The “attack surface” for criminals is diverse. Cyber-villains most often first gained access to production environments through errant users clicking malicious links, visiting unsecure websites or engaging with phishing emails — again exposing the avoidable nature of many incidents. After having successfully gained access to the environment, there was very little difference in the infection rates between data center servers, remote office platforms and cloud-hosted servers.
In most cases, the intruders took advantage of known vulnerabilities, including common operating systems and hypervisors, as well as NAS platforms and database servers, leaving no stone unturned and exploiting any unpatched or outdated software that they can find. It is notable that significantly higher infection rates were reported by Security Professionals and Backup Administrators, compared with IT Operations or CISOs, implying that “those closer to the problem see even more of the issues.”
Remediation starts with immutability
Respondents to the survey confirmed that 94% of attackers attempted to destroy backup repositories and in 72% of cases this strategy was at least partially successful. This removal of an organization’s recovery lifeline is a popular attack strategy as it increases the likelihood that victims would have no other choice than to pay the ransom.
The only way to protect against this scenario is to have at least one immutable or air-gapped tier within the data protection framework — which 95% of those we surveyed stated they now have. In fact, many organizations reported having some level of immutability or air-gap media in more than one tier of their disk, cloud and tape strategy.
Other key findings
- Orchestration matters: To proactively ensure recoverability of their systems, one in six (16%) IT teams automate the validation and recoverability of their backups to ensure their servers are restorable. Then, during remediation of a ransomware attack, 46% of respondents use an isolated “sandbox” or staging/test area to ensure their restored data is clean prior to reintroducing the systems into production.
- Organization alignment must unify: 81% believe their organizations’ cyber and business continuity/disaster recovery strategies are aligned. However, 52% of respondents believe the interactions between these teams requires improvement.
- Diversifying the repositories holds the key: 95% of organizations have at least one immutable or air-gapped data protection tier, 74% use cloud repositories that offer immutability; 67% use on-premises disk repositories with immutability or locking; and 22% use tape that is air-gapped. Immutable or not, organizations noted that in addition to disk repositories, 45% of production data is still stored on tape and 62% goes into a cloud at some point in their data lifecycle.
