Growing Ransomware Woes Are Swamping These 3 Sectors
3 Sectors Are the Hardest Hit But No Sector is Safe
Ransomware is an unwelcome visitor to any business. The bane of every IT professional, it’s a dominant threat in the security ecosystem that just keeps growing. In a recent survey, 90% of IT pros had clients that suffered ransomware attacks in the past year. IT prof and business owners have to confront the fact that ransomware is headed their way no matter what size their organization is –50% of ransomware attacks hit SMBs with less than 100 employees – or what industry they’re in. But there are a few industries that are at the top of the cybercriminal hit list, and companies in those fields have a higher risk of attack than others.

The Financial Sector is Rich with Ransomware Risk
The most beleaguered sector of late 2021 was Banking and Finance. Supplying a constant stream of breathless headlines, almost one-quarter (22%) of ransomware attacks in the last part of 2021 were directed at organizations in the money business. For the banking industry, the entire year was a dangerous time to do business. Banking and Finance targets saw a 1,318% increase in the number of ransomware attacks waged against it in the first half of 2021.
This trend is easy to see in action in other parts of the financial ecosystem as well. Bad actors are laying siege to anything that even touches finance including cryptocurrency exchanges and De Fi targets. DeFi fraud and hacks combined for a total of $474 million lost just in the first half of 2021, with at least one De Fi platform in trouble every week. DeFi-related cybercrime made up 76% of all major hacks in 2021 as cybercriminals flocked to snatch their piece of the cryptocurrency pie.

Infrastructure is Squarely in Cybercriminals’ Sights
Next up, one-fifth of ransomware attacks (20%) in the last half of the year were aimed at utility companies. Over 1,300 organizations in the Utilities sector including critical services, infrastructure, and supporting industrial targets were impacted by ransomware in 2021. This growing trend sent shockwaves around the world as people outside the tech industry began realizing that cyberattacks can be used as weapons against key strategic targets. Cyber-physical systems (CPS) company Claroty announced in a recent report that 80% of critical infrastructure organizations experienced a ransomware attack in last year.
That is a grave concern for governments around the world. Last year’s incident with Colonial Pipeline brought the danger of infrastructure attacks home to politicians and average citizens alike. Ransomware threats against infrastructure targets have become such an acute problem that they were called out specifically in a joint advisory released by Cybersecurity and Infrastructure Security Agency (CISA), Federal Bureau of Investigation (FBI), the National Security Agency (NSA), the United Kingdom’s National Cyber Security Centre (NCSC-UK) and the Australian Cyber Security Centre (ACSC) on Wednesday, February 9, 2022. In that release, officials disclosed that ransomware attacks targeted 14 of the 16 critical infrastructure sectors in 2021.

No Industry is Above the Fray
Retailers take third place on the target list with organizations in that sector enduring 16% of ransomware attacks in late 2021. That beleaguered industry also took a monumental beating in 2020, with retail cyberattacks soaring by increasing by 1280% during the pandemic. The pressure eased in 2021 but cybercriminals were all gunning for retailers, an excellent source of valuable PII and financial data. Retailers that were hit with ransomware were left with big bills to pay in uncertain economic times. The average bill for cleaning up a ransomware attack in the retail sector was an estimated $1.97 million.
Other sectors didn’t get off easy though. Altogether, The US has incurred a 127% year-to-date increase in the number of ransomware attacks while the UK has seen a 233% surge. IT professionals struggled to contain the ransomware flood that swamped businesses in every sector in 2021 and it doesn’t look like their job is going to get any easier in 2022. A study from Unitrends MSP of more than 200 IT professionals from MSP organizations worldwide detailed their experiences, and it wasn’t pretty. The vast majority of IT pros were aware of the epic growth of ransomware and it’s impact on their clients all too well.
In the Last 24 Months, Ransomware Has…
- Become a significant risk 89%
- Stayed the same 5%
- Diminished 2%
- Not Sure 5%
How are cybercriminals delivering all of this ransomware to businesses? IBM’s Cyber Resilient Organization Study offers a breakdown of the most likely ways that ransomware gets to targeted organizations. When considering organizations that sustained at least one ransomware attack in 2021, researchers determined that four major causes represented the catalyst for ransomware events.
How Organizations Encountered Ransomware
- Phishing or Social Engineering 45%
- Insecure or Spoofed Websites 22%
- Social Media 19%
- Malvertisements 13%
When digging deeper into the origin point of ransomware for organizations in every industry, a few interesting findings pop up that really illustrate the variety of ways that a business can come into contact with ransomware. In a recent study on cybersecurity trends, researchers determined that most ransomware infections are self-inflicted, with 8 out of 10 ransomware incidents spawned by the victim interacting with a zipped file containing malicious code. More than 90% of those attacks were geared towards Microsoft O365 users while Google Workspace users got off relatively lightly at 1% of attacks. Other origin stories included abuse of third-party access at 3% and exploiting software vulnerabilities at 4% of all ransomware incidents.

The Aftermath of a Ransomware Incident is Brutal

Unitrends MSP researchers determined that for companies that have faced ransomware head-on, data loss (22.34%) and downtime (22.13%) were and reputation damage (15.24%), were the top three consequences reported. Expanding on that, lost profits (13.57%) and compliance failures (9.39%) round out the top five.
Consequences of a Ransomware Attack for Clients

- Lost Data 22%
- Lost Profits 14%
- Data Recovered (Paid Ransom) 5%
- Data Lost (Paid Ransom) 6%
