FortiGuard Labs Reports Tenfold Increase in Ransomware

Published

on

Fortinet has announced the latest semiannual FortiGuard Labs Global Threat Landscape Report. Threat intelligence from the first half of 2021 demonstrates a significant increase in the volume and sophistication of attacks targeting individuals, organizations, and increasingly critical infrastructure. The expanding attack surface of hybrid workers and learners, in and out of the traditional network, continues to be a target. Timely collaboration and partnership momentum across law enforcement, as well as public and private sectors, is an opportunity to disrupt the cybercriminal ecosystem going into the second half of 2021.

Ransomware Is About Much More Than Just Money
FortiGuard Labs data shows average weekly ransomware activity in June 2021 was more than tenfold higher than levels from one year ago. This demonstrates a consistent and overall steady increase over a year period. Attacks crippled the supply chains of multiple organizations, in particular sectors of critical importance, and impacted daily life, productivity, and commerce more than ever before.

Organizations in the telecommunications sector were the most heavily targeted followed by government, managed security service providers, automotive, and manufacturing sectors. In addition, some ransomware operators shifted their strategy away from email-initiated payloads to focusing on gaining and selling initial access into corporate networks further showing the continued evolution of Ransomware-as-a-Service (RaaS) fueling cybercrime.

A key takeaway is that ransomware remains a clear and present danger for all organizations regardless of industry or size. Organizations need to take a proactive approach with real-time endpoint protection, detection, and automated response solutions to secure environments along with a zero-trust access approach, network segmentation, and encryption.

One in Four Organizations Detected Malvertising
Ranking the prevalence of top malware detections by malware families shows a rise in deceptive social engineering malvertising and scareware. More than one in four organizations detected malvertising or scareware attempts with Cryxos being a notable family. Although, a large volume of the detections is likely combined with other similar JavaScript campaigns that would be considered malvertising.

The hybrid work reality has undoubtedly encouraged this trend in tactics by cybercriminals as they attempt to exploit it, aiming for not just a scare but also extortion. Increased cybersecurity awareness is important as ever to provide timely training and education to help avoid falling victim to scareware and malvertising tactics.

Botnet Trends Show Attackers Push to the Edge
Tracking the prevalence of botnet detections showed a surge inactivity. At the beginning of the year, 35% of organizations detected botnet activity of one sort or another, and six months later it was 51%. A large bump in TrickBot activity is responsible for the overall spike in botnet activity during June.

TrickBot originally emerged on the cybercrime scene as a banking trojan but has since been developed into a sophisticated and multi-stage toolkit supporting a range of illicit activities. Mirai was the most prevalent overall; it overtook Gh0st in early 2020 and has reigned ever since well into 2021.

Mirai has continued adding new cyberweapons to its arsenal, but it is likely that Mirai’s dominance at least still partially stems from criminals seeking to exploit Internet-of-Things (IoT) devices used by work-from-home or learning-from-home individuals. Gh0st is also noticeably active, which is a remote access botnet that allows attackers to take full control of the infected system, capture live webcam and microphone feeds, or download files.

More than a year into remote work and learning shifts, cyber adversaries continue to target our evolving daily habits to exploit the opportunity. To protect networks and applications, organizations need zero-trust access approaches to provide the least access privileges to secure against IoT endpoints and devices entering the network.

Disruption of Cybercrime Shows Reduced Threat Volumes
In cybersecurity, not every action has an immediate or lasting effect, but several events in 2021 show positive developments specifically for defenders. The original developer of TrickBot was arraigned on multiple charges in June. Also, the coordinated takedown of Emotet, one of the most prolific malware operations in recent history, as well as actions to disrupt the Egregor, NetWalker, and Cl0p ransomware operations represent significant momentum by cyber defenders, including global governments and law enforcement to curb cybercrime.

In addition, the level of attention that some attacks garnered spooked a few ransomware operators to announce they were ceasing operations. FortiGuard Labs’ data showed a slowdown of threat activity following the Emotet takedown. Activity related to TrickBot and Ryuk variants persisted after the Emotet botnet was taken offline, but it was at a reduced volume. This is a reminder of how hard it is to eradicate cyber threats or adversary supply chains immediately, but these events are important achievements regardless.

Defensive Evasion and Privilege Escalation Techniques Favored by Cybercriminals
Studying higher resolution threat intelligence reveals valuable takeaways about how attack techniques are evolving currently. FortiGuard Labs analyzed the specific functionality inherent to detected malware by detonating the samples to observe what the intended outcome was for cyber adversaries.

The result was a list of negative things malware would have accomplished if the attack payloads had been executed in target environments. This shows cyber adversaries sought to escalate privileges, evade defenses, move laterally across internal systems, and exfiltrate compromised data, among other techniques. For example, 55% of observed privilege escalation functionality leveraged hooking, and 40% utilized process injection.

A takeaway is that there is an obvious focus on defense evasion and privilege escalation tactics. Although these techniques are not novel, defenders will be better positioned to secure against future attacks, armed with this timely knowledge. Integrated and artificial intelligence (AI)-driven platform approaches, powered by actionable threat intelligence, are essential to defend across all edges and to identify and remediate shifting threats organizations face today in real-time.

Derek Manky, Chief, Security Insights and Global Threat Alliances, FortiGuard Labs, said, “We are seeing an increase in effective and destructive cyberattacks affecting thousands of organizations in a single incident creating an important inflection point for the war on cybercrime. Now more than ever, everyone has an important role in strengthening the kill chain. Aligning forces through collaboration must be prioritized to disrupt cybercriminal supply chains. Shared data and partnership can enable more effective responses and better predict future techniques to deter adversary efforts. Continued cybersecurity awareness training, as well as AI-powered prevention, detection, and response technologies integrated across endpoints, networks, and the cloud, remain vital to counter cyber adversaries.”

While government and law enforcement agencies have taken actions relative to cybercrime in the past, the first half of 2021 could be a game-changer in terms of the momentum for the future. They are working with industry vendors, threat intelligence organizations, and other global partnership organizations to combine resources and real-time threat intelligence to take direct action against cyber adversaries.

Regardless, automated threat detection and AI remain essential to enable organizations to address attacks in real-time and to mitigate attacks at speed and scale across all edges. In addition, cybersecurity user awareness training is as important as ever with anyone being a target of cyberattacks. Everyone needs regular instruction on best practices to keep individual employees and the organization secure.

ESET Research Uncovers Iran-Aligned BladedFeline Spying on Iraqi, Kurdish Officials

Published

on

The Iran-aligned threat group BladedFeline has targeted Kurdish and Iraqi government officials in a recent cyber-espionage campaign, according to ESET researchers. The group deployed a range of malicious tools discovered within the compromised systems, indicating a continued effort to maintain and expand access to high-ranking officials and government organizations in Iraq and the Kurdish region. The latest campaign highlights BladedFeline’s evolving capabilities, featuring two tunneling tools (Laret and Pinar), various supplementary tools, and, most notably, a custom backdoor Whisper and a malicious Internet Information Services (IIS) module PrimeCache, both identified and named by ESET.

Whisper logs into a compromised webmail account on a Microsoft Exchange server and uses it to communicate with the attackers via email attachments. PrimeCache also serves as a backdoor: it is a malicious IIS module. PrimeCache also bears similarities to the RDAT backdoor used by OilRig Advanced Persistent Threat (APT) group.

Based on these code similarities, as well as on further evidence presented in this blogpost, ESET assesses that BladedFeline is a very likely subgroup of OilRig, an Iran-aligned APT group going after governments and businesses in the Middle East. The initial implants in the latest campaign can be traced back to OilRig. These tools reflect the group’s strategic focus on persistence and stealth within targeted networks.

BladedFeline has consistently worked to maintain illicit access to Kurdish diplomatic officials, while simultaneously exploiting a regional telecommunications provider in Uzbekistan, and developing and maintaining access to officials in the government of Iraq.

ESET Research assesses that BladedFeline is targeting the Kurdish and Iraqi governments for cyberespionage purposes, with an eye toward maintaining strategic access to the computers of high-ranking officials in both governmental entities. The Kurdish diplomatic relationship with Western nations, coupled with the oil reserves in the Kurdistan region, makes it an enticing target for Iran-aligned threat actors to spy on and potentially manipulate. In Iraq, these threat actors are most probably trying to counter the influence of Western governments following the US invasion and occupation of the country.

In 2023, ESET Research discovered that BladedFeline targeted Kurdish diplomatic officials with the Shahmaran backdoor, and previously reported on its activities in ESET APT Activity reports. The group has been active since at least 2017, when it compromised officials within the Kurdistan Regional Government, but is not the only subgroup of OilRig that ESET Research is monitoring. ESET has been tracking Lyceum, also known as HEXANE or Storm-0133, as another OilRig subgroup. Lyceum focuses on targeting various Israeli organizations, including governmental and local governmental entities and organizations in healthcare.

ESET expects that BladedFeline will persist with implant development in order to maintain and expand access within its compromised victim set for cyberespionage.

Cloud Security Trade-Offs Rise: 91% of Leaders Face AI Threats

Published

on

Gigamon has released its 2025 Hybrid Cloud Security Survey, revealing that hybrid cloud infrastructure is under mounting strain from the growing influence of artificial intelligence (AI). The annual study, now in its third year, surveyed over 1,000 global Security and IT leaders across the globe. As cyberthreats increase in both scale and sophistication, breach rates have surged to 55 percent during the past year, representing a 17 percent year-on-year (YoY) rise, with AI-generated attacks emerging as a key driver of this growth.

Security and IT teams are being pushed to a breaking point, with the economic cost of cybercrime now estimated at $3 trillion worldwide according to the World Economic Forum. As AI-enabled adversaries grow more agile, organizations are challenged with ineffective and inefficient tools, fragmented cloud environments, and limited intelligence.

Key findings highlight how ai is reshaping hybrid cloud security priorities:

  • AI’s role in escalating network complexity and accelerating risk is evident. The study reveals that 46 percent of Security and IT leaders say managing AI-generated threats is now their top security priority. One in three organizations report that network data volumes have more than doubled in the past two years due to AI workloads, while nearly half of all respondents (47 percent) are seeing a rise in attacks targeting their organization’s large language model (LLM) deployments. More than half (58 percent) say they’ve seen a surge in AI-powered ransomware—up from 41 percent in 2024 underscoring how adversaries are exploiting AI to outpace and outflank existing defenses.
  • Compromises highlight continued trade-offs in foundational areas of hybrid cloud security. Nine out of ten (91 percent) Security and IT leaders concede to making compromises in securing and managing their hybrid cloud infrastructure. The key challenges that create these compromises include the lack of clean, high-quality data to support secure AI workload deployment (46 percent) and lack of comprehensive insight and visibility across their environments, including lateral movement in East-West traffic (47 percent).
  • Public cloud risks prompt industry recalibration. Once considered an acceptable risk in the rush to scale post-COVID operations, the public cloud is now coming under increasingly intense scrutiny. Many organizations are rethinking their cloud strategies in the face of their growing exposure, with 70 percent of Security and IT leaders now viewing the public cloud as a greater risk than any other environment. As a result, 70 percent report their organization is actively considering repatriating data from public to private cloud due to security concerns and 54 percent are reluctant to use AI in public cloud environments, citing fears around intellectual property protection.
  • Visibility is top of mind for security leaders. As cyberattacks become more sophisticated, the limitations of existing security tools are coming sharply into focus. Organizations are shifting their priorities toward gaining complete visibility into their environments, a capability now seen as crucial for effective threat detection and response. More than half (55 percent) of respondents lack confidence in their current tools’ ability to detect breaches, citing limited visibility as the core issue. As a result, 64 percent say their number one focus for the next 12 months is achieving real-time threat monitoring delivered through having complete visibility into all data in motion.

With AI driving unprecedented traffic volumes, risk, and complexity, nearly nine in 10 (89 percent) Security and IT leaders cite deep observability as fundamental to securing and managing hybrid cloud infrastructure. Executive leadership is taking notice, as boards increasingly prioritize complete visibility into all data in motion, with 83 percent confirming that deep observability is now being discussed at the board level to better protect hybrid cloud environments.

“Security teams are struggling to keep pace with the speed of AI adoption and the growing complexity and vulnerability of public cloud environments,” said Mark Jow, technical evangelist, EMEA, at Gigamon. “Deep observability addresses this challenge by combining MELT data with network-derived telemetry such as packets, flows, and metadata, delivering increased visibility and amore informed view of risk. It enables teams to eliminate visibility gaps, regain control, and act proactively with increased confidence. With 88 percent of Security and IT leaders agreeing it is critical to securing AI deployments, deep observability is fast becoming a strategic imperative.”

“With nearly half of organizations saying attackers are already targeting their large language models, AI security can’t be an afterthought, it needs to be a top priority,” said Mark Walmsley, CISO at Freshfields. “The key to staying ahead? Visibility. When we can clearly see what’s happening across AI systems and data flows, we can cut through the noise and manage risk more effectively. Deep observability helps us spot vulnerabilities early and put the right protections in place before issues arise.”

Axis Communications Sheds Light on Video Surveillance Industry Perspectives on AI

Published

on

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.
