A new State of Ransomware in Retail 2022 report from Sophos found that retail had the second highest rate of ransomware attacks last year of all sectors surveyed after the media, leisure, and entertainment industry. Globally, 77 percent of retail organizations surveyed were hit—a 75 percent increase from 2020. This is also 11 percent more than the cross-sector average attack rate of 66 percent.
“Retailers continue to suffer one of the highest rates of ransomware attacks of any industry,” said Chester Wisniewski, principal research scientist at Sophos. “With more than three in four suffering an attack in 2021, it certainly brings a ransomware incident into the category of when, not if. In Sophos’ experience, the organizations that are successfully defending against these attacks are not just using layered defenses, they are augmenting security with humans trained to monitor for breaches and actively hunting down threats that bypass the perimeter before they can detonate into even bigger problems. This year’s survey shows that only 28 percent of retail organizations targeted were able to stop their data from being encrypted, suggesting that a large portion of the industry needs to improve their security posture with the right tools and appropriately trained security experts to help manage their efforts.”
As the percentage of retail organizations attacked by ransomware increased, so did the average ransom payment. In 2021, the average ransom payment was $226,044, a 53 percent increase when compared to 2020 ($147,811). However, this was less than one-third the cross-sector average ($812K).
“It’s likely that different threat groups are hitting different industries,” Wisniewski said. “Some of the low-skill ransomware groups ask for $50,000 to $200,000 in ransom payments, whereas the larger, more sophisticated attackers with increased visibility demand $1 million or more. With Initial Access Brokers (IABs) and Ransomware-as-a-Service (RaaS), it’s unfortunately easy for bottom-rung cybercriminals to buy network access and a ransomware kit to launch an attack without much effort. Individual retail stores and small chains are more likely to be targeted by these smaller opportunistic attackers.”
Additional findings include:
- While the retail sector was the second most targeted industry, the perceived increase in the volume and complexity of cyberattacks against the industry were slightly below the cross-sector average (55 percent and 55 percent respectively)
- 92 percent of retail organizations hit by ransomware said the attack impacted their ability to operate and 89 percent said the attack caused their organization to lose business/revenue
- In 2021, the overall cost to retail organizations to remediate a ransomware attack was $1.27M, down from $1.97M in 2020
- When compared to 2020, the amount of data recovered after paying the ransom decreased (from 67 percent to 62 percent), as did the percentage of retail organizations that got all their data back (from 9 percent to 5 percent)
In the light of the survey findings, Sophos experts recommend the following best practices for all organizations across all sectors:
- Install and maintain high-quality defenses across all points in the environment. Review security controls regularly and make sure they continue to meet the organization’s needs
- Proactively hunt for threats to identify and stop adversaries before they can execute attacks. If the team lacks the time or skills to do this in-house, outsource to a Managed Detection and Response (MDR) team
- Harden the IT environment by searching for and closing key security gaps: unpatched devices, unprotected machines and open RDP ports, for example. Extended Detection and Response (XDR) solutions are ideal for this purpose
- Prepare for the worst, and have an updated plan in place of a worst case incident scenario
- Make backups, and practice restoring them to ensure minimal disruption and recovery time
