Sophos Labs conducted a global cybersecurity survey, sharing the findings in a document dubbed The State of Ransomware 2020.
The report reveals that paying cybercriminals to restore data encrypted during a ransomware attack is not just an expensive mess, but also a hard path to recovery. In fact, it reports that the total cost of recovery almost doubles when organizations pay a ransom.
The survey polled 5,000 IT decision-makers in organizations in 26 countries across six continents, including Europe, the Americas, Asia-Pacific, and central Asia, the Middle East, and Africa.
“More than half (51%) of organizations had experienced a significant ransomware attack in the previous 12 months, compared to 54% in 2017. In the MEA region, 43% of the organizations surveyed mentioned a ransomware attack in the last year. Globally Data was encrypted in nearly three quarters (73%) of attacks that successfully breached an organization, while in the MEA region, it was 63%,” reads the report in part.
It continues that the average cost of addressing the impact of such attacks, including business downtime, lost orders, operational costs, and more, but not including the ransom, was more than US $730,000. This average cost, it notes, rose to US $1.4 million, almost twice as much, when organizations paid the ransom.
More than one quarter (27%) of organizations hit by ransomware admitted to paying the ransom. The survey also revealed 23% of the organizations that were attacked in the MEA region admitted to paying the ransom.
“Organizations may feel intense pressure to pay the ransom to avoid damaging downtime. On the face of it, paying the ransom appears to be an effective way of getting data restored, but this is illusory. Sophos’ findings show that paying the ransom makes little difference to the recovery burden in terms of time and cost. This could be because it is unlikely that a single magical decryption key is all that’s needed to recover. Often, the attackers may share several keys, and using them to restore data may be a complex and time-consuming affair,” said Chester Wisniewski, principal research scientist, Sophos.
More than half (56%) of the IT managers surveyed were able to recover their data from backups without paying the ransom compared to 60% in the MEA region. In a very small minority of cases (1%) globally and 3% in the MEA region, paying the ransom did not lead to the recovery of data. This figure rose to 5% for public sector organizations. In fact, 13% of the public sector organizations surveyed never managed to restore their encrypted data, compared to 6% overall.
However, contrary to popular belief, the public sector was least affected by ransomware, with just 45% of the organizations surveyed in this category saying they were hit by a significant attack in the previous year. At a global level, media, leisure, and entertainment businesses in the private sector were most affected by ransomware, with 60% of respondents reporting attacks.
Increased pressure to pay
SophosLabs researchers published another report, Maze Ransomware: Extorting Victims for 1 Year and Counting, which looks at the tools, techniques, and procedures used by this advanced threat, that combines data encryption with information theft and the threat of exposure.
This approach, which Sophos researchers have also observed being adopted by other ransomware families, like LockBit, is designed to increase pressure on the victim to pay the ransom. The new Sophos report will help security professionals better understand and anticipate the evolving behaviors of ransomware attackers and protect their organizations.
“An effective backup system that enables organizations to restore encrypted data without paying the attackers is business critical, but there are other important elements to consider if a company is to be truly resilient to ransomware,” avered Wisniewski.
Advanced adversaries like the operators behind the Maze ransomware don’t just encrypt files, they steal data for possible exposure or extortion purposes.
“We’ve recently reported on LockBit using this tactic. Some attackers also attempt to delete or otherwise sabotage backups to make it harder for victims to recover data and increase pressure on them to pay. The way to address these malicious maneuvers is to keep backups offline and use effective, multi-layered security solutions that detect and block attacks at different stages,” Wisniewski added.
The State of Ransomware 2020 survey was conducted by Vanson Bourne, an independent specialist in market research, in January and February 2020. The survey interviewed 5,000 IT decision-makers in 26 countries, in the US, Canada, Brazil, Colombia, Mexico, France, Germany, the UK, Italy, the Netherlands, Belgium, Spain, Sweden, Poland, the Czech Republic, Turkey, India, Nigeria, South Africa, Australia, China, Japan, Singapore, Malaysia, Philippines, and UAE. All respondents were from organizations with between 100 and 5,000 employees.
