MUMBAI, MAY 20
Over 80% of Indian organizations had experienced a significant ransomware attack in the previous 12 months, compared to 67% in 2017, cybersecurity firm Sophos has said in its global report – The State of Ransomware 2020. Data was encrypted in 91% of attacks that successfully breached an organization in India. The average cost of addressing the impact of such an attack in India, including business downtime, lost orders, operational costs, and more, was ₹8 crores. Two out of three (66%) organizations hit by ransomware in India admitted paying the ransom, a company report said.
“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.
Nearly 30% of the IT managers surveyed in India were able to recover their data from backups without paying the ransom. Every organization in India that paid the ransom got their data back, although this was not always the case elsewhere. Globally, nearly 5% of public sector organizations paid the ransom but didn’t get their data back. 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 globally, 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.
Attackers increase pressure to pay
SophosLabs researchers have published a new 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,” added 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.”
