There are two essential methods to get well encrypted knowledge in a ransomware assault: restoring from backups and paying the ransom. Compromising a company’s backups allows adversaries to limit their sufferer’s capacity to get well encrypted knowledge and dial-up the strain to pay the ransom.
This evaluation explores the influence of backup compromise on the enterprise and operational outcomes of a ransomware assault. It additionally shines gentle on the frequency of profitable backup compromise throughout a variety of industries.
The findings are based mostly on a vendor-agnostic survey commissioned by Sophos of two,974 IT/cybersecurity professionals whose organizations had been hit by ransomware within the final 12 months. Performed by impartial analysis company Vanson Bourne in early 2024, the research displays respondents’ experiences over the earlier 12 months.
Govt abstract
The evaluation makes clear that monetary and operational implications of getting backups compromised in a ransomware assault are immense. When attackers achieve compromising backups, a company is nearly twice as more likely to pay the ransom and incurs an general restoration invoice that’s eight instances increased than for these whose backups will not be impacted.
Detecting and stopping malicious actors earlier than your backups are compromised lets you scale back significantly the influence of a ransomware assault in your group. Investing in stopping backup compromise each elevates your ransomware resilience whereas additionally decreasing the general Complete Price of Possession (TCO) of cybersecurity.

Studying 1: Ransomware actors virtually all the time try to compromise your backups
94% of organizations hit by ransomware prior to now 12 months stated that the cybercriminals tried to compromise their backups throughout the assault. This rose to 99% in each state and native authorities, and the media, leisure and leisure sector. The bottom fee of tried compromise was reported by distribution and transport, nonetheless even right here greater than eight in ten (82%) organizations hit by ransomware stated the attackers tried to entry their backups.
Studying 2: Backup compromise success fee varies significantly by business
Throughout all sectors, 57% of backup compromise makes an attempt have been profitable, which means that adversaries have been in a position to influence the ransomware restoration operations of over half of their victims. Curiously, the evaluation revealed appreciable variation in adversary success fee by sector:
Attackers have been probably to efficiently compromise their victims’ backups within the vitality, oil/fuel, and utilities (79% success fee) and schooling (71% success fee) sectors
Conversely, IT, know-how and telecoms (30% success fee) and retail (47% success fee) reported the bottom charges of profitable backup compromise
There are a number of potential causes behind the differing success charges. It could be that IT, telecoms and know-how had stronger backup safety in place to begin with so was higher ready to withstand the assault. They could even be simpler at detecting and stopping tried compromise earlier than the attackers may succeed. Conversely, the vitality, oil/fuel and utilities sector could have skilled the next proportion of very superior assaults. Regardless of the trigger, the influence could be appreciable.
Studying 3: Ransom calls for and funds double when backups are compromised
Knowledge encryption
Organizations whose backups have been compromised have been 63% extra more likely to have knowledge encrypted than those who didn’t: 85% of organizations with compromised backups stated that the attackers have been in a position to encrypt their knowledge in contrast with 52% of these whose backups weren’t impacted. The upper encryption fee could also be indicative of weaker general cyber resilience which leaves organizations much less in a position to defend towards all phases of the ransomware assault.
Ransom demand
Victims whose backups have been compromised acquired ransom calls for that have been, on common, greater than double that of these whose backups weren’t impacted, with the median ransom calls for coming in at $2.3M (backups compromised) and $1M (backups not compromised) respectively. It’s seemingly that adversaries really feel that they’re in a stronger place in the event that they compromise backups and so are in a position to demand the next cost.
Ransom cost fee
Organizations whose backups have been compromised have been virtually twice as more likely to pay the ransom to get well encrypted knowledge than these whose backups weren’t impacted (67% vs. 36%).
Ransom cost quantity
The median ransom cost by organizations whose backups have been compromised was $2M, virtually double that of these whose backups remained intact ($1.062M). They have been additionally much less in a position to negotiate down the ransom cost, with these whose backups have been compromised paying, on common, 98% of the sum demanded. These whose backups weren’t compromised have been in a position to scale back the cost to 82% of the demand.
Studying 4: Ransomware restoration prices are 8X increased when backups are compromised
Not all ransomware assaults end in a ransom being paid. Even once they do, ransom funds are simply a part of the general restoration prices when coping with a ransomware assault. Ransomware-led outages continuously have a substantial influence on day-to-day enterprise transactions whereas the duty of restoring IT techniques is commonly complicated and costly.
The median general ransomware restoration prices for organizations whose backups have been compromised ($3M) got here in eight instances increased than that of organizations whose backups weren’t impacted ($375K). There are seemingly a number of causes behind this distinction, not least the extra work that’s sometimes wanted to revive from decrypted knowledge slightly than well-prepared backups. It could even be that weaker backup safety is indicative of much less sturdy defenses and better ensuing rebuilding work wanted.
These whose backups have been compromised additionally skilled significantly longer restoration time with simply 26% totally recovered inside per week in contrast with 46% of these whose backups weren’t impacted.
Suggestions
Backups are a key a part of a holistic cyber threat discount technique. In case your backups are accessible on-line, it’s best to assume that adversaries will discover them. Organizations can be clever to:
Take common backups and retailer in a number of places. Make sure you add MFA (multi-factor authentication) to your cloud backup accounts to assist stop attackers from gaining entry.
Apply recovering from backups. The extra fluent you’re within the restoration course of, the faster and simpler it will likely be to get well from an assault.
Safe your backups. Monitor for and reply to suspicious exercise round your backups as it could be an indicator that adversaries are trying to compromise them.
