Banking, government, and transportation industries as big game targets

Our sensors showed that the banking, government, and transportation (BGT) sectors ranked as ransomware operators¡¯ most targeted industries in the first half of 2021. While ?such as dormant WannaCry variants were still highly tracked by our sensors, modern ransomware has made its way into this report's list of ransomware families with most detections. REvil (also known as Sodinokibi) has been consistently detected in BGT. Threat actors have been known to use this ransomware in modern ransomware attacks, which are targeted or advanced persistent threat (APT)-like in nature. These attacks also often use double extortion techniques that threaten victims with publicizing stolen sensitive data if they don¡¯t pay the ransom.

Even prior to the drastic business shifts caused by the pandemic, these groups inherently have unique business characteristics that make for a wide attack surface: the in locally, the number of and , of , that inhibit cybersecurity measures¡¯ implementation, the of they offer the public, and the likelihood of these industries paying the ransom to protect their customers¡¯ data and restore systems at the soonest.

Banking

Banks are attractive targets for ransomware operators because apart from offering various financial services, the types of information that can be stolen from the banking industry (such as credit card and bank account details) are highly sensitive and profitable. live casino online sensors detected over 130,000 ransomware attack attempts in the sector, with banks in the Americas as having the highest number of ransomware counts recorded in the first half of the year.

The lucrative business of banks makes it a prized target for sophisticated attackers who have been known for profiling and conducting financial health studies of organizations to determine the next potential targets. The most recent attack against the industry was reported in June, where a was allegedly hit by Avaddon, another modern ransomware family. The active modern ransomware families we found in this sector for the first half of the year are REvil and (aka Dharma).

Potential impact of attacks on the banking sector:

• On average, a consumer is estimated to own ; an attack on one ¡¯²õ or infrastructure could affect at least 9,090 adults and more than 45,000 accounts.
• Small- and mid-sized banks to attack more organizations within and outside the financial industry via different service platforms. Stoppage or closure of these local branches can affect communities and other critical sectors significantly.
• Attacks and ransom payments could potentially violate other such as Know Your Customer (KYC), Anti-Money Laundering (AML), and Combatting Financing of Terrorism (CFT) laws in the US.

Government

The Center for Internet Security¡¯²õ (CIS) Multi-State Information Sharing & Analysis Center () cited that its 11,000 members 75 ransomware attacks across the US between January to June. Meanwhile, a conducted in early 2021 showed that entities in the central government and non-departmental public body (NDPB) are more likely to experience ransomware double extortion attacks.

Government agencies make attractive ransomware targets for various reasons. Stored , such as social security numbers and voters¡¯ information, serve as low-hanging fruit for data . Modern ransomware operators capable of stealing information prior to ransomware implementation could make additional profit by selling the stolen data somewhere else. live casino online recorded more than 82,000 ransomware attack attempts, with the most counts in the African region¡¯²õ government systems, followed by those in Asia and the Middle East.

Potential impact of attacks on the government sector:

• Largest paid ransom: $592,000 (2019, Florida) (Source: )
• Largest amount paid for recovery post-ransomware attack: $18 million (2019, Baltimore) (Source: )
• Local governments serve as and reflection of a wider . An attack on a local government office¡¯²õ infrastructure or individual affects local, national, and digital security such as taxes, financials, identification, investments, and public services, among others.
• Fiscal and audit mandates the potential development of resources and capabilities of agencies to prepare, respond, and recover from ransomware attacks on their own. This can prolong service downtimes, without local or municipal functions such as traffic, sanitation, and healthcare.

Transportation

Weekly ransomware attacks in the transportation industry have increased by from 2019 to 2020. Given the interconnected nature of aviation, maritime, logistics, and ground shipping and transport, an abrupt disruption of normal functions ensures on businesses, people¡¯²õ welfare, and national security, and a potentially hefty payday for attackers. While vehicles¡¯ own IT systems can be infected and attacked, it is their land/shore-based systems that remain vulnerable: systems and devices in data centers and offices used to manage details for operations are viable targets. live casino online sensors detected over 32,000 ransomware attack attempts in this sector, with the most counts observed in Asia and the Middle East.

Ransomware attack attempts against the transportation industry by region

The first publicly known ransomware attack in the US freight rail sector was . OmniTRAX, a US-based railroad transportation company, confirmed that it was hit by the Conti ransomware gang. The attackers reportedly published stolen data on a leak site ¨C a common double extortion tactic used by modern ransomware operators. Meanwhile, one of the most recent attacks against the transportation industry involved Death Kitty ransomware, nearly causing the operations of to a complete halt.

With the high number of modern ransomware families targeting the transportation sector, it is highly likely that threat actors banked on organizations becoming desperate for operations to resume in the event of a disruption. As the priority is on minimizing potential downtime during incidents, transportation companies are more likely to pay the ransom to resume operations as soon as possible. The modern ransomware families highly observed in this sector are REvil, Ryuk, Conti, and DarkSide.

Potential impact of attacks on the transportation sector:

• The transportation sector ties together all supply chains worldwide, making it a tempting target for all kinds of malicious profiteering activities. A ransomware attack on one of the major transit systems could give attackers valuable information encompassing the Eastern and Western hemispheres, potentially crippling economies and supply chains.
• The sector lies at the heart of businesses¡¯ and economies¡¯ supplier-consumer delivery interdependence, making it a significant point of infection after infiltration.
• The sudden interruption of public transportation and its related services can cause real threats to life such as those for emergency services, road accidents, and infrastructure damage (e.g., trains¡¯ schedules and direction mishaps).

The real costs of a ransomware attack

Apart from the running costs of downtime and ransom paid, recovery via decryption keys a return to normal operations. However, the true of a ransomware attack becomes apparent during recovery.

Financial: Operations downtime, fines, and recovery

Considering that not all companies report attacks, the number of victims and accumulated amounts of ransom paid may be higher than what official reports show. But according to Coveware, the average ransomware payments for organizations reached US$136,576 in Q2 2021. While large enterprises can afford cyber insurance, a single attack on an SMB may be enough to put them altogether. Reports that the average ransom demanded from modern ransomware attacks reached over $5 million. In addition, potential regulatory fines and litigation settlements also add up to the costs of payments and recovery. The average downtime for every ransomware attack has increased to compared to 16 days in 2020,?compared to 12 days in 2019, and initial system, file, and (in some instances) infrastructure recovery adds to downtime expenses.

Reputation damage

In a study of ransomware attack impact on businesses, who participated in the study said ransomware attacks not only included losses in revenue, but also unplanned employee layoffs and damage to the brand due to the diversion of allocations for recovery. From a consumer perspective, loyal subscribers can also redirect their attention to the competition when cyber incidents arise. In a study analyzing customers¡¯ loyalty to brands, are able to retract their loyalty to brands compared to prior years, and 61% are able to switch some or all of their business to another provider within a year.

Modern ransomware¡¯²õ extortion methods come in different phases and has progressed over time. Aside from locking systems and files, these are some of the other techniques ransomware operators employ to threaten victims and inflict reputational damage on organizations:

• Posting data in leak sites
• Posting data in underground forums and blogs
• Distributed denial of service (DDoS)
• Direct contact of customers, victim¡¯²õ business partners, and the media
• Auction of stolen data

Cyber insurance sector¡¯²õ maturity

Cyber insurance companies are also noting that premiums have gone up and requirements for coverage should have a security baseline. that for payments are causing attacks, an adapting industry is beginning to agree that companies should comply with security prerequisites before giving ransomware coverage claims. technologies, practices, and have to be in place, acknowledging that investments in prevention and recovery is still cheaper and better than dealing with attack costs and the aftermath.

Overview of 2021 1H Ransomware Detections Across Industries

Other critical sectors did not go unscathed. We observed the total ransomware attack attempts against enterprises were at 3,600,439, with BGT closely followed by other critical sectors that experienced major adjustments in the past months for business continuity. Moreover, live casino online observed the addition of 49 new ransomware families during the first half of the year.

As ransomware operates on a global scale, the inclusion of these countries as the most targeted countries in 1H can be attributed to the number of multinational companies and business interests stationed in them.

Top ransomware families in 1H 2021

The dominant presence of premodern ransomware families such as WannaCry point to the latency of its components in systems, implicating the longevity and persistence of worm-based network variants due to unpatched devices.?While this is expected to continue decreasing as more systems are replaced with better technologies and solutions, industries are strongly advised to pay attention to detecting and blocking the growing numbers of modern ransomware deployed.

How to deter ransomware and minimize its impact

Persistent ransomware groups will find ways to attack organizations and industries, and a ransomware compromise is no longer a matter of ¡°if¡± but ¡°when.¡± Organizations can mitigate the risks of ransomware with these best practices:

1. Continuous education and awareness programs. Implement a consistent learning and awareness program for all the employees and partners of the organization. Get IT, development, security, and incident response (IR) teams to spearhead security programs so everyone recognizes their roles in maintaining the systems¡¯ security.
2. Invest in cross-layered detection and response solutions. Enable technical improvement and technological solutions that can anticipate and respond to ransomware activities, techniques, and movements before it can launch an attack. An integrated and cohesive solution enables simultaneous monitoring and tracking of all the potential entry points. Emails, servers, networks, endpoints, mobile, cloud storage, and workloads should have multilayered protection systems that can keep and prevent ransomware from running. A cybersecurity platform that provides visibility into the early activities of modern ransomware attacks, such as live casino online Vision One?? with Managed XDR, helps detect and block ransomware components to stop attacks before threat actors are able to exfiltrate sensitive data.
3. Create an incident response (IR) team and playbook for prevention and recovery. Invest in IR teams, as well as a playbook applicable to the company¡¯²õ make-up and covers a broad base. IR allow an organization to plan and prepare for attacks such as ransomware and breaches. Constantly update the security and incident playbook as a guide that everyone can follow when the need arises.
   
   A cyber incident implies that all preventive measures and enabled defenses have been exhausted and have failed. If properly structured and implemented, an included in the playbook activates the team to prioritize, contain, and stop a cyberattack even without identifying the actors behind the compromise. By qualifying and identifying the gap or threats that breached the defenses, an IR team and playbook can ensure that:
   1. Procedures are in place to enable a business to run again after an attack.
   2. Forensics can look into the incident in-depth after the threat has been terminated.
   3. The same incident or threat will not happen again.
4. Practice attack simulations. Include a for cyberattacks that everyone in the workplace can use. A swift response strategy from everyone can minimize the impact and damage at crucial points. These can give decision-makers, security, and IR teams an idea of what to anticipate and prepare for, such as the potential gaps for abuse and pressure points in systems and with people.
