Ransomware: Financial institutions spent over $2m in recovery costs in 2020 — Sophos

The latest report from the next-generation cybersecurity company, Sophos on the state of Ransomware in the Financial Sector has revealed that mid-sized financial services organisations worldwide spent over $2 million on average in recovering from a ransomware attack.

According to the firm, the figure exceeds the global average of $1.85 million, even though the results also show the financial sector is among the most resilient against ransomware.

It also revealed that nearly two-thirds of victims surveyed in this sector were able to restore their encrypted data from backups. The survey studied the extent and impact of ransomware attacks during 2020.

Other findings include: 34 per cent of the financial services organisations surveyed were hit by ransomware in 2020.

Then 51 per cent of the organisations impacted said the attackers succeeded in encrypting their data and only 25 per cent paid the ransom demanded to get their encrypted data back. This is the second lowest payment rate of all industries surveyed. The global average was 32 per cent.

Financial services is among the most highly regulated industries in the world. Organisations must adhere to myriad regulations, including SOX, GDPR, and PCI DSS, that include pricey penalties for non-compliance and data breaches. Many of these organisations are also required to prepare business continuity and disaster recovery plans to minimize any potential damage from data breaches or operational disruptions stemming from a cyberattack.

Senior Security Advisor at Sophos, John Shier, said: “Strict guidelines in the financial services sector encourage strong defenses. “Unfortunately, they also mean that a direct hit with ransomware is likely to be very costly for targeted organisations.

If you add up the price of regulatory fines, rebuilding IT systems and stabilizing brand reputation, especially if customer data is lost, you can see why the survey found that recovery costs for mid-sized financial services organisations hit by ransomware in 2020 were in excess of $2 million.

“Two other slightly worrying data points are the fact that a small, but significant 8% of financial services organisations experienced what are known as ‘extortion’ attacks, where data is not encrypted, but stolen and victims are threatened with the online publication of their data unless they pay the ransom.

Backups cannot protect against this risk, so financial services organisations should not rely on them as an anti-extortion defense. Further, 11 per cent of the financial organisations surveyed believe they won’t get hit because they are ‘not a target.’ This is a dangerous perception because anyone can be a target. The best approach is to assume you will be a target and to build your defenses accordingly.”

Of the financial services organisations that believe they’ll be hit by ransomware in the future, 47% said this is because attacks are now so sophisticated they have become harder to stop. Forty-five percent feel they’ll become a target because other organizations in their industry have already been targeted with ransomware. Forty percent believe that since ransomware is so prevalent, it is inevitable they’ll get hit by the cybercrime.

“The financial sector has too much at stake to not set up an indepth defensive plan to protect, dectect and block cyberattackers,” said Shier. “While they should continue to invest in backups and their disaster recovery efforts to minimize the impact of an attack, they should also look to extend their anti-ransomware defenses by combining technology with human-led threat hunting to neutralize today’s advanced human-led cyberattacks.”

The State of Ransomware in Financial Services 2021 survey polled 5,400 IT decision makers, including 550 in financial services organizations, in 30 countries across Europe, the Americas, Asia-Pacific and Central Asia, the Middle East, and Africa.
