2022 in Review: 10 of the Year’s Biggest Cyberattacks
Written by Phil Muncaster, guest writer at ESET
The past year has seen the global economy lurch from one crisis to another. As COVID-19 finally began to recede in many regions, what replaced it has been rising energy bills, soaring inflation, and a resulting cost-of-living crisis – some of it spurred by Russia’s invasion of Ukraine. Ultimately, these developments have opened the door to new opportunities for financially-motivated and state-backed threat actors.
They have targeted governments, hospitals, cryptocurrency firms, and many other organisations with impunity. The cost of a data breach now stands at nearly $4.4 million – and as long as threat actors continue to achieve successes like those below, we can expect it to rise even higher for 2023.
Here are 10 of the worst cyber incidents of the year, be it for the damage they wrought, the level of sophistication, or geopolitical fallout. The list is in no particular order, but it makes sense to open it with malicious cyber operations that took aim at Ukraine and immediately raised concerns about their wider ramifications and associated cyber risks faced by the wider world.
Ukraine under (cyber)attack: Ukraine’s critical infrastructure has found itself, yet again, in the crosshairs of threat actors. Early into Russia’s invasion, ESET researchers worked closely with CERT-UA on remediating an attack that targeted the country’s grid and involved destructive malware that Sandworm had attempted to deploy against high-voltage electrical substations. The malware – which ESET named Industroyer2 after an infamous piece of malware used by the group to cut power in Ukraine in 2016 – was used in combination with a new version of the destructive CaddyWiper variant, most likely to hide the group’s tracks, slow down incident response and prevent operators of the energy company from regaining control of the ICS consoles.
More wipers: CaddyWiper was far from the only destructive data wiper discovered in Ukraine just before or in the first few weeks of Russia’s invasion. On February 23rd, ESET telemetry picked up HermeticWiper on hundreds of machines in several organizations in Ukraine. The following day, a second destructive, data-wiping attack against a Ukrainian governmental network started, this time delivering IsaacWiper.
Internet down: Barely an hour before the invasion, a major cyberattack against commercial satellite internet company Viasat disrupted broadband internet service for thousands of people in Ukraine and even elsewhere in Europe, leaving behind thousands of bricked modems. The attack, which exploited a misconfigured VPN device to gain access to the satellite network’s management section, is believed to have been intended to impair the communication capabilities of the Ukrainian command during the first hours of the invasion. Its effects were felt far beyond Ukraine’s borders, however.
Conti in Costa Rica: A major player in the cybercrime underground this year was the ransomware-as-a-service (RaaS) group Conti. One of its most audacious raids was against the small South American nation of Costa Rica, where a national emergency was declared after the government branded a crippling attack an act of “cyber-terrorism.” The group has since disappeared, although its members are likely to simply have moved on to other projects or rebranded wholesale, as RaaS outfits generally due to avoid scrutiny from law enforcers and governments.
Other ransomware actors: There were also in action in 2022. A CISA alert from September explained that Iran-affiliated threat actors compromised a US municipal government and an aerospace company, among other targets, by exploiting the infamous Log4Shell bug for ransomware campaigns, which isn’t all that common for state-backed entities. Also intriguing was a US government compromise in November that was also blamed on Iran. An unnamed Federal Civilian Executive Branch (FCEB) organization was breached and crypto mining malware was deployed.
Ronin Network: This was created by Vietnamese blockchain game developer Sky Mavis to function as an Ethereum sidechain for its Axie Infinity game. In March it emerged that hackers managed to use hijacked private keys to forge withdrawals to the tune of 173,600 Ethereum ($592 million) and $25.5 million from the Ronin bridge, in two transactions. The resulting $618 million theft, at March prices, was the largest ever from a crypto firm. Infamous North Korean group Lazarus has since been linked to the raid. The hermit nation has been traced in the past to thefts worth billions of dollars, used to fund its nuclear and missile programs.
Lapsus$: This burst onto the scene in 2022, as an extortion group using high-profile data thefts to force payment from its corporate victims. These have included Microsoft, Samsung, Nvidia, Ubisoft, Okta and Vodafone. Among its many methods are bribery of insiders at firms and their contractors. Although the group had been relatively silent for a while, it re-emerged at the end of the year after hacking Grand Theft Auto developer Rockstar Games. Several alleged members of the group have been arrested in the UK and Brazil.
International Red Cross (ICRC): In January, the ICRC reported a major breach that compromised the personal details of over 515,000 “highly vulnerable” victims. Stolen from a Swiss contractor, the data included details of individuals separated from their families due to conflict, migration, and disaster, missing persons and their families, and people in detention. It was subsequently blamed on an unnamed nation-state and occurred when an unpatched system was exploited.
Uber: The ride-hailing giant was famously breached back in 2016 when details on 57 million users were stolen. In September it was reported that a hacker, potentially a member of Lapsus$, had compromised email and cloud systems, code repositories, an internal Slack account, and HackerOne tickets. The actor targeted an Uber external contractor, most likely grabbing their corporate password from the dark web.
Medibank: All of the Australian health insurance giant’s four million customers have personal data accessed by ransomware actors in an attack that may end up costing the firm US$35 million. Those responsible are believed to be linked to the infamous ransomware-as-a-service (RaaS) outfit REvil (aka Sodinokibi) with compromised privileged credentials responsible for initial access. Those impacted now face a potential barrage of follow-on identity fraud attempts.
Whatever happens in 2023, some of the cautionary tales from these 10 major incidents should stand everybody, including CISOs, in good stead. Get your cybersecurity processes and operations right, organize cybersecurity awareness training for all employees, and partner with reputable security companies whose solutions can stand up to the complex methods deployed by threat actors.

Positive Technologies Reports 80% of Middle East Cyberattacks Compromise Confidential Data
A new study by cybersecurity firm Positive Technologies has shed light on the evolving cyber threat landscape in the Middle East, revealing that a staggering 80% of successful cyberattacks in the region lead to the breach of confidential information. The research, examining the impact of digital transformation, organized cybercrime, and the underground market, highlights the increasing exposure of Middle Eastern nations to sophisticated cyber threats.
The study found that one in three successful cyberattacks were attributed to Advanced Persistent Threat (APT) groups, which predominantly target government institutions and critical infrastructure. While the rapid adoption of new IT solutions is driving efficiency, it simultaneously expands the attack surface for malicious actors.
Cybercriminals in the region heavily utilize social engineering tactics (61% of cases) and malware (51%), often employing a combination of both. Remote Access Trojans (RATs) emerged as a primary weapon in 27% of malware-based attacks, indicating a common objective of gaining long-term access to compromised systems.
The analysis revealed that credentials and trade secrets (29% each) were the most sought-after data, followed by personal information (20%). This stolen data is frequently leveraged for blackmail or sold on the dark web. Beyond data theft, 38% of attacks resulted in the disruption of core business operations, posing significant risks to critical sectors like healthcare, transportation, and government services.
APT groups are identified as the most formidable threat actors due to their substantial resources and advanced technical capabilities. In 2024, they accounted for 32% of recorded attacks, with a clear focus on government and critical infrastructure. Their activities often extend beyond traditional cybercrime, encompassing cyberespionage and even cyberwarfare aimed at undermining trust and demonstrating digital dominance.
Dark web analysis further revealed that government organizations were the most frequently mentioned targets (34%), followed by the industrial sector (20%). Hacktivist activity was also prominent, with ideologically motivated actors often sharing stolen databases freely, exacerbating the cybercrime landscape.
The United Arab Emirates, Saudi Arabia, Israel, and Qatar, all leaders in digital transformation, were the most frequently cited countries on the dark web in connection with stolen data. Experts suggest that the prevalence of advertisements for selling data from these nations underscores the challenges of securing rapidly expanding digital environments, which cybercriminals are quick to exploit.
Positive Technologies analyst Alexey Lukash said, “In the near future, we expect cyberthreats in the Middle East to grow both in scale and sophistication. As digital transformation efforts expand, so does the attack surface, creating more opportunities for hackers of all skill levels. Governments in the region need to focus on protecting critical infrastructure, financial institutions, and government systems. The consequences of successful attacks in these areas could have far-reaching implications for national security and sovereignty.”
To help organizations build stronger defenses against cyberthreats, Positive Technologies recommends implementing modern security measures. These include vulnerability management systems to automate asset management, as well as identify, prioritize, and remediate vulnerabilities. Positive Technologies also suggests using network traffic analysis tools to monitor network activity and detect cyberattacks. Another critical layer of protection involves securing applications. Such solutions are designed to identify vulnerabilities in applications, detect suspicious activity, and take immediate action to prevent attacks.
Positive Technologies emphasizes the need for a comprehensive, result-driven approach to cybersecurity. This strategy is designed to prevent attackers from disrupting critical business processes. Scalable and flexible, it can be tailored to individual organizations, entire industries, or even large-scale digital ecosystems like nations or international alliances. The goal is to deliver clear, measurable results in cybersecurity—not just to meet compliance standards or rely on isolated technical fixes.

Axis Communications Sheds Light on Video Surveillance Industry Perspectives on AI
Axis Communications has published a new report that explores the state of AI in the global video surveillance industry. Titled The State of AI in Video Surveillance, the report examines the key opportunities, challenges and future trends, as well as the responsible practices that are becoming critical for organisations in their use of AI. The report draws insights from qualitative research as well as quantitative data sources, including in-depth interviews with carefully selected experts from the Axis global partner network.
A leading insight featured in the report is the unanimous view among interviewees that interest in the technology has surged over the past few years, with more and more business customers becoming curious and increasingly knowledgeable about its potential applications.

Mats Thulin, Director AI & Analytics Solutions at Axis Communications
“AI is a technology that has the potential to touch every corner and every function of the modern enterprise. That said, any implementations or integrations that aim to drive value come with serious financial and ethical considerations. These considerations should prompt organisations to scrutinise any initiative or investment. Axis’s new report not only shows how AI is transforming the video surveillance landscape, but also how that transformation should ideally be approached,” said Mats Thulin, Director AI & Analytics Solutions at Axis Communications.
According to the Axis report, the move by businesses from on-premise security server systems to hybrid cloud architectures continues at pace, driven by the need for faster processing, improved bandwidth usage and greater scalability. At the same time, cloud-based technology is being combined with edge AI solutions, which play a crucial role by enabling faster, local analytics with minimal latency, a prerequisite for real-time responsiveness in security-related situations.
By moving AI processing closer to the source using edge devices such as cameras, businesses can reduce bandwidth consumption and better support real-time applications like security monitoring. As a result, the hybrid approach is expected to continue to shape the role of AI in security and unlock new business intelligence and operational efficiencies.
A trend that is emerging among businesses is the integration of diverse data for a more comprehensive analysis, transforming safety and security. Experts predict that by integrating additional sensory data, such as audio and contextual environmental factors caught on camera, can lead to enhanced situational awareness and greater actionable insights, offering a more comprehensive understanding of events.
Combining multiple data streams can ultimately lead to improved detection and prediction of potential threats or incidents. For example, in emergency scenarios, pairing visual data with audio analysis can enable security teams to respond more quickly and precisely. This context-aware approach can potentially elevate safety, security and operational efficiency, and reflects how system operators can leverage and process multiple data inputs to make better-informed decisions.
According to the Axis report, interviewees emphasised that responsible AI and ethical considerations are critical priorities in the development and deployment of new systems, raising concerns about decisions potentially based on biased or unreliable AI. Other risks highlighted include those related to privacy violations and how facial and behavioural recognition could have ethical and legal repercussions.
As a result, a recurring theme among interviewees was the importance of embedding responsible AI practices early in the development process. Interviewees also pointed to regulatory frameworks, such as the EU AI Act, as pivotal in shaping responsible use of technology, particularly in high-risk areas. While regulation was broadly acknowledged as necessary to build trust and accountability, several interviewees also stressed the need for balance to safeguard innovation and address privacy and data security concerns.
“The findings of this report reflect how enterprises are viewing the trend of AI holistically, working to have a firm grasp of both how to use the technology effectively and understand the macro implications of its usage. Conversations surrounding privacy and responsibility will continue but so will the pace of innovation and the adoption of technologies that advance the video surveillance industry and lead to new and exciting possibilities,” Thulin added.
