Regardless of elevated consciousness amongst organizations about cybersecurity, ransomware assaults are going up. Cyber extortionists are concentrating on organizations and governments with impunity, holding their information hostage and demanding ransom within the vary of hundreds of thousands of {dollars}.
Such is the severity that international ransomware damages are anticipated to cross $30 billion by 2023. And as per the most recent Value of a Information Breach Report by IBM, information breach prices have surged 13% from 2020 to 2022, with the common information breach value reaching a file excessive in 2022 at $4.35 million USD.
That will help you be taught extra about ransomware assaults—how they occur, what they appear to be, and the way (or whether or not) firms are capable of get better afterwards, here’s a survey of some latest examples of real-life ransomware assaults.
However first, let’s check out the state of the ransomware “business.”
Ransomware by the numbers
Detailed analysis on ransomware developments by cybersecurity firm NordLocker on 5,212 firms between January 2020 and July 2022 reveals that:
- The collective income of focused firms was $4.15 trillion.
- The USA was the primary nation most affected by ransomware.
- The highest 5 industries most impacted by ransomware had been manufacturing, development, transportation, IT, and healthcare.
- Greater than 12 million staff had been affected.
- Organizations with annual income between $10 and $25 million USD are focused extra by ransomware, however that doesn’t imply smaller firms are protected.
Ransomware gangs are creating havoc, forcing governments to take motion. One working example is the infamous Conti ransomware gang, accountable for a number of high-profile assaults over the previous two years.
Given the seriousness of the scenario, the U.S. Division of State even provided a grand reward of $15 million to determine co-conspirators of the Conti ransomware gang and supply details about any particular person planning or trying to take part in a Conti ransomware assault.
Nevertheless, the consequences of ransomware are vital regardless of the scale of a enterprise, says Kenneth Henao, founder and president of BCA IT. In spite of everything, paying the ransom cash isn’t the one factor enterprise house owners have to fret about.
“It’s the price of downtime, the harm to their status, and the pricey penalties and fines for non-compliance that always damage a enterprise essentially the most,” mentioned Henao. “In some instances, the losses will be so damaging that small companies, specifically, may not have the ability to get better from the assault.”
4 cautionary examples of ransomware assaults
Ransomware assaults can are available many sorts, shapes, and sizes—and so they can goal nearly anyone, from a single particular person to the biggest firms. (In fact, the larger the corporate, the more cash the criminals are capable of attempt extorting.) Among the greatest and most high-profile ransomware assaults in latest reminiscence have been the assaults on Colonial Pipeline, Travelex, Nvidia, and the federal government of Costa Rica.
Colonial Pipeline assault brought on a gasoline scarcity
Ransom demanded: $5 million {dollars}
On Might 7, 2021, Colonial Pipeline was hit by a ransomware assault that crippled the pipeline’s IT programs for days. Fearing that the malware would unfold to the operational know-how community that controls pipeline operations, the corporate determined to close down the complete pipeline of 5,500 miles in an effort to stop additional harm.
However doing so created chaos and panic. Frightened a few gasoline scarcity, East Coast residents began panic-buying gasoline, with some hoarding it in plastic baggage. Lengthy strains had been reported at many shops, gasoline costs shot up, and even the airline business was affected.
The Russian-based DarkSide gang behind the assault gained entry to the system by a compromised digital non-public community (VPN) password and requested for a ransom of $5 million {dollars}. Given the escalating scenario and the panic throughout, Colonial Pipeline agreed to pay the ransom quantity. Fortuitously, U.S. legislation enforcement brokers managed to get better $2.3 million in Bitcoin of the ransom cash.
Following the assault and different related assaults like SolarWinds and Microsoft Change, the Biden administration issued an government order that features utilizing a software program invoice of supplies (SBOMs), sharing risk info between the federal government and personal sector, implementing sturdy cybersecurity requirements within the federal authorities, amongst different measures supposed to curb the specter of ransomware assaults.
Travelex pressured to shut following ransomware assault
Ransom demanded: £4.6 million ($5.53 million USD)
In January 2020, a ransomware gang known as Sodinokibi (also called REvil) attacked journey insurance coverage model Travelex, demanding £4.6 million ($5.53 million USD) in ransom cash.

After about two weeks of disruption and at last paying $2.3 million in Bitcoin, Travelex managed to revive its on-line providers. Nonetheless, COVID-19 and the ransomware assault took its toll, and the corporate went bankrupt in August 2020.
Nvidia chip information stolen and worker passwords leaked
No financial ransom demanded
On Feb. 25, 2022, Nvidia, the biggest microchip firm on this planet, was attacked by the ransomware group LAPSUS$, which stole proprietary info and worker private information totaling 1TB and commenced leaking it on-line.
In an untypical transfer, the group didn’t demand any ransom cash however as a substitute wished Nvidia to disable the lite hast price (LHR) characteristic that places limits on the efficiency of GPUs—particularly, stopping customers from utilizing them for cryptocurrency mining. The group additionally wished the corporate to open-source its GPU drivers for Linux, Home windows, and Mac units.
Though a comparatively new entrant, the LAPSUS$ group shot to fame by concentrating on large firms like Impresa (Portugal’s largest media channel), Brazilian telecommunications firm Claro, Brazil’s Ministry of Well being, Microsoft, Samsung, and Okta.
The group makes use of a wide range of methods like redline password-stealing malware to entry confidential data, paying firm insiders for credential entry, social engineering, and SIM swapping to efficiently goal victims.
What’s fascinating is that a lot of the masterminds behind the LAPSUS$ group are youngsters. The group is mendacity low after the U.Ok. police arrested seven folks aged 16 to 21 in April 2022 for alleged connections to the LAPSUS$ group. Nevertheless, how lengthy this lasts is open to hypothesis.
Costa Rican authorities pressured to declare state of emergency

The scenario was so dire that newly elected President Rodrigo Chaves needed to declare a state of emergency. Contemplating that it was the primary time a rustic declared a nationwide emergency in response to a ransomware assault, this incident obtained a variety of media protection.
Way forward for ransomware assaults
Sadly, ransomware assaults aren’t stopping anytime quickly. Quite, we’re going to see more and more extra developed and complicated types of ransomware assaults. In actual fact, in its newest Rising Dangers Monitor Report, Gartner lists “new ransomware fashions” as the highest concern going through executives.
“We’re particularly seeing ransomware as a service (RaaS) changing into extra frequent,” mentioned Henao.
Much like different as-a-service fashions, RaaS is a subscription-based mannequin that allows hackers to purchase already-built ransomware instruments to orchestrate assaults.
“Absolutely conscious of how worthwhile ransom assaults are, cybercriminals are promoting their ransomware kits by the darkish internet to attackers who may not have the required technical abilities to launch ransomware assaults themselves,” mentioned Henao.
This makes RaaS all of the extra harmful as a result of even hackers with restricted abilities can now launch assaults.
Along with RaaS, double extortion ransomware and triple extortion ransomware are the newer types of ransomware cybercriminals are utilizing. In a double extortion assault, criminals enter the sufferer’s community, transfer laterally, encrypt the info, after which demand a ransom. In triple extortion, the ransom is directed not solely towards the corporate but in addition its clients. Collectively, these methods, together with RaaS, have the aptitude to deliver a corporation to its knees.

- Disable Distant Desktop Protocol (RDP) if it’s not wanted to cut back the chance of unauthorized system entry.
Within the phrases of Ali Allage, CEO of BlueSteel Cybersecurity: “It’s all about doing the basics persistently earlier than you bounce too far into the deep finish of complication. Fundamentals are: fundamental entry management plan (who, what, the place, and why), gadget administration (antivirus, backups, distant wiping), classifying the info you maintain as delicate and non-sensitive, incident response plan (if one thing had been to occur, who would you name, and the way will you deal with it?), and backing up every thing.”
Backside line: Combating ransomware assaults
These examples present that ransomware has the potential to trigger huge harm to organizations, deliver down essential establishments, and compromise nationwide safety.
