Organizational Preparedness will Help Protect Against Unorthodox Cyber Attack

Type of AI based attack vectors & organizational preparedness to Threat mitigation in 2026

AI based attacks is already there and what’s more, now organizations need to protect themselves against any unorthodox attack vector’s i.e AI based. Organizational readiness to thwart any unorthodox attack vectors like AI will determine organizational security from cyber threats are.

Any preparedness by organizations to protect and combat AI powered cyber Attacks will take lot of precession as AI based attack occur at scale and speed both. In backdrop of any cyber attack that is not common how do organization’s prepare and what does statistics from 2025 reveal.

Most of AI powered attacks are not conventional in nature and traditional cybersecurity tools often struggle to respond effectively to these threat.

AI-enabled attack that organizations need to prepare for in 2026

For organizations dealing with an attack vector which are unorthodox or AI in nature require man power or skilled cyber force and tools that are automated to detect and thwart the attack before they advance towards the institutions in advance.

AI’s has capacity to process and learn vast amounts of data and in cybersecurity this is termed as powerful and presents unique challenges as well as risks. Present attack scenario we have witnessed how AI take to automate and optimize malicious activity.

For defenders AI is boon and can detect, predict and mitigate threats in real time. However, the increasing sophistication of AI-powered threats is outpacing traditional defense mechanisms.

What are the types of AI powered Attack

Hacking which is Automated and AI algorithms based, can identify and exploit vulnerabilities faster than human capabilities.
Next in line is AI- Phishing and Cybercriminals use AI to create personal and convincing phishing emails. What AI does here is to analyze data from other sources to generate highly customized messages capable of influencing.
Deepfakes are growing in form of realistic fake videos or audio impersonating public figures in order to spread misinformation, manipulate public opinion, or conduct social engineering attacks. 
Corrupting AI Models via data fed into AI systems to manipulate outcomes and is particularly concerning in critical systems. This showcases the dangerous potential of AI-powered cyber attacks.

Key findings by Organizations – AI based cyber security findings.

The evolving nature of AI means that new attack vectors are constantly being developed, making detection difficult for organizations. These are below mentioned take aways from 2025 regarding AI driven cyber threats.

  • 51% of European IT and cybersecurity professionals feared AI-driven cyber threats and deepfakes will keep them up at night in 2026
  • Only 14% feel their organizations are ‘very prepared’ to manage the risks associated with generative AI
  • Other concerns for the year ahead include regulatory complexity, ransomware attacks, and the failure to detect and respond to a breach, causing irreparable harm to the business
  • Less than half of organizations plan to hire more talent to manage and mitigate these concerns
  • In the Cisco 2025 Cybersecurity Readiness Index: 86% of business leaders with cyber responsibilities reported at least one AI-related incident over the past 12 months.
  • IBM reports that 51% of enterprises now use security AI or automation, and those organizations experience $1.8 million lower average breach costs than those without it.
  • Trend Micro’s mid-2025 scans revealed over 200 unprotected Chroma servers and 3,000+ AI components publicly exposed online, allowing data theft or model poisoning.

What do cyber security leadership require most in 2026 is having clear actionable path regarding AI based attack and threat mitigation.

A mindset change is required by CEOs, CISO’s and CXOs where focus should be to start building resilience against intelligent AI attacks.

Cybersecurity has become integral part of lives and especially 2025 was the year of cybercrimes and data breaches across verticals. As the new year commences, starting the year on a positive note with cyber-security resolutions such as

Evolving Phishing Scams & Cost Incurred by Organization’s in 2025

Any phishing scams that occur, the purpose is to trick unsuspecting victims or organizations into taking a specific action and that can range from clicking on malicious links, downloading harmful files or sharing login credentials. Sometimes the effectiveness of phishing attacks stems from their use of social engineering techniques that have the ability to exploit human psychology or behavior. In 2025 we have witnessed the how evolving phishing scams that have affected organizations financially.

Often we see phishing scams create a sense of urgency, or curiosity thereby prompting victims to act quickly without verifying the authenticity of incoming request. Now with evolving technology, phishing tactics are also evolving making these attacks increasingly sophisticated, hard to detect. In coming years we will witness how AI will power more phishing attacks, including text-based impersonations to deepfake communications. These will be more cheap and popular with threat actors.

Cyber security researchers found that there is a link between ransomware, malware and form encryption and most were caused by.

14% Malicious websites

54% Phishing

27% Poor user pactices / gullibility

26% Lack of cybersecurity training

A survey by Statista found that ransomware infections were caused by:

  • 54% Phishing
  • 27% Poor user pactices / gullibility
  • 26% Lack of cybersecurity training
  • 14% Malicious websites

In this blog we will highlight latest phishing statistics that emerged in 2025 ,affecting organizations and phishing scams are changing.

As per APWG report found on Unique phishing sites. This is a primary measure of reported phishing across the globe. This is determined by the unique bases of phishing URLs found in phishing emails reported to APWG’s repository.

In the first quarter of 2025, APWG observed 1,003,924 phishing attacks. This was the largest quarterly
total since 1.07 million were observed in Q4 2023. The number has climbed steadily over the last year:
from 877,536 in Q2 2024, to 932,923 in Q3, to 989,123 in Q4. One of the reason cited being advancement in AI is also making it easier for criminals to create convincing and personalized phishing lures.

Hoxhunt find alarming statistics on phishing related attack of 2025

Business email compromise (BEC)A staggering 64% of businesses report facing BEC attacks in 2024, with a typical financial loss averaging $150,000 per incident​. These phishing attacks frequently target employees with access to financial systems, mimicking executives or trusted contacts.
Credential phishingAround 80% of phishing campaigns aim to steal credentials, particularly targeting cloud-based services like Microsoft 365 and Google Workspace. With the growing reliance on cloud platforms, cyber attackers leverage realistic fake login pages to deceive users.
HTTPS phishingAn increasing number of phishing sites now use HTTPS to appear legitimate. In 2024, approximately 80% of phishing websites feature HTTPS, complicating detection for users.
Voice phishing (vishing)Vishing attacks are growing in prevalence, with 30% of organizations reporting instances where threat actors used fake calls to impersonate officials or executives.
Quishing (QR code phishing)QR code phishing attacks (quishing) increased by 25% year-over-year, as attackers exploit physical spaces like posters or fake business cards to lure victims.
AI-driven attacksAI is powering phishing attacks, with deepfake impersonations increasing by 15% in the last year. These attacks often target high-value individuals in finance and HR.
Multi-channel phishingAttackers are increasingly exploiting platforms like Slack, Teams, and social media. Around 40% of phishing campaigns now extend beyond email, reflecting a shift to these channels.
Government agency impersonationPhishing emails mimicking government bodies such as the IRS or international tax agencies have increased by 35%. These often involve claims about overdue taxes or fines.
Phishing kitsThe availability of ready-to-use phishing kits on the dark web has risen by 50%, enabling less sophisticated attackers to deploy high-quality phishing schemes​.
Brand impersonationAttackers frequently impersonate well-known brands like Microsoft, Amazon, and Facebook, leveraging user trust. For example, over 44,750 phishing attacks specifically targeted Facebook by embedding its name in domains and subdomains​ over the past year.

Cost of Phishing attacks

According to the 2024 IBM / Ponemon Cost of a Data Breach study, the average annual cost of phishing rose by nearly 10% from 2024 to 2023, from $4.45m to $4.88m. That’s the biggest jump since the pandemic.

The IBM study reported the following costs:

  • Phishing breaches: $4.88M
  • Social engineering: $4.77M
  • BEC: $4.67M

The above-listed categories of cyber security breach costs are all related to people-targeted attacks. BEC, social engineering, and stolen credentials often contain a phishing element.

Barracuda research found that email remains the common attack vector for cyber threats and highlighted their key findings:

1 in 4 email messages are malicious or unwanted spam.

83% of malicious Microsoft 365 documents contain QR codes that lead to phishing websites.

20% of companies experience at least one account takeover (ATO) incident each month.

Nearly one-quarter of all HTML attachments are malicious and more than three-quarters of
companies are not actively preventing spoofed emails.

Bitcoin sextortion scams, an emerging trend, account for 12% of malicious PDF attachments.

Nearly half of all companies have not configured a DMARC policy, putting them at risk
of email spoofing, phishing attacks, and business email compromise.

The Barracuda research also found malicious one in four emails are either malicious or unwanted spam and malicious attachment is prevalent in various file.

An alarming 87% of binaries detected were malicious, highlighting the need for strict policies against executable files being sent via email, since they can directly install malware. Despite a relatively low total volume, HTML files have a high malicious rate of 23% and are often used for phishing and credential theft.

The research say that small businesses more vulnerable to email threats, due to limited cybersecurity resources, smaller IT teams and they rely on basic email security solutions. Small business may not have required solutions to handle sophisticated attacks, such as business email compromise (BEC), phishing and ransomware.

How Organizations can strengthen their defense

As organizations embark to strengthen their defenses, it’s crucial they don’t overlook the human element and Cybersecurity hygiene. That definitely starts by identifying security at every step starting from ensuring every user, machine or system that has right to access privileges.

Cybersecurity is as much a cultural issue as it is a technical one, as a single click can compromise an entire organization, behavior starts to shift from compliance to accountability 

Whenever there is a successful phishing attack, researchers emphasize that this attack succeeds by exploiting human trust and familiarity with corporate communication formats. Security awareness remains the most vigorous defense as the growing complexity of these campaigns indicates that phishing operations are increasingly automated, data-driven and adaptive.

Conclusion: As organizations move towards adopting AI, so as attackers to continuously refining their tactics, evade traditional security measures. In this scenario organizations must mitigate the risks by adopting a multi-layered approach to email security. This will include all from leveraging AI-driven threat detection, real-time monitoring and user awareness training.

Phishing Detection & DeepPhish

For organizations who reply on unlike traditional rule-based phishing detection, which relies on blacklists and predefined rules. DeepPhish is implemented, that continuously learns from new phishing attempts, making it highly adaptive and effective against evolving threats.

DeepPhish employs a multi-layered AI approach to detect phishing threats and theses include Email and Website Analysis,uses ML algorithms to analyze historical phishing attacks and identify new patterns and NLP helps DeepPhish analyze email content, message tone, and linguistic patterns that phishers use to trick users.

Unpatched Systems, Software’s Exposes Business to Cyber Threats

Remember when Qantas, Australia’s flagship airline confirmed a cyberattack exposing data from its frequent flyer program and customer accounts. The data was upto 6 million, which is staggering in number. This means any kind of exploits are malicious programs designed to take advantage of bugs or vulnerabilities in unpatched software or operating systems to gain unauthorised access. When left unpatched, these weak points act as open doors for cybercriminals.

Kaspersky research shows that the share of exploits targeting critical vulnerabilities in operating systems reached 64% in Q2 2025 (up from 48% in Q1 2025), with third-party apps (29%) and browsers (7%) following.

Unpatched Systems, Software’s exposes Business to Cyber Threats

The breach originated from a third-party customer service platform, proving that even indirect systems can expose millions of records we all knew. This was a clear case how unpatched software’s but Qantas denied any of its service platform was vulnerable and there was no sign the platform was compromised.

Similarly 1.5 billion records across 760 global companies record exposed to data breach when Salesforce was hit and the hacking group claimed to have breached Salesforce through compromised integrations with third-party tools like Drift and SalesLoft, stealing huge amounts of CRM data. And as recent Salesloft Drift cyberattack may have also compromised some Google Workspace accounts.

The above case are all about software vulnerabilities when left unpatched. Latest data from cybersecurity and privacy company Kaspersky revealed that existing vulnerabilities in business networks continue to leave Malaysian enterprises exposed to cyberattacks.

Globally, in Q2 2025, the most common exploits targeted vulnerable Microsoft Office products with unpatched security flaws, according to Kaspersky’s findings. Its solutions detected the most exploits on the Windows platform for the following vulnerabilities:

  • CVE-2018-0802: Remote code execution vulnerability in the Equation Editor component
  • CVE-2017-11882: Another remote code execution vulnerability in Equation Editor
  • CVE-2017-0199: Vulnerability in Microsoft Office and WordPad allowing attackers to gain control of the system

(Source: Kaspersky: Unpatched Systems Expose Malaysian Businesses To Exploits – TechTRP)

The report also revealed that the top 10 most exploited vulnerabilities included both new zero-day flaws and older unpatched issues that organisations continue to overlook. A zero-day vulnerability is a software flaw discovered by attackers before the vendor is aware of it. As no patch exists at the time, zero-day attacks often succeed.

Key findings from Kaspersky reports to secure your unpatched systems

  • Increased Exploitation: In the first half of 2025, more Windows and Linux users encountered vulnerability exploits compared to the previous year.
  • Targeted Vulnerabilities: Common exploits in Q2 2025 targeted Microsoft Office products with unpatched security flaws, such as those in the Equation Editor (CVE-2018-0802 and CVE-2017-11882).
  • End of Support: The end of free support for Windows 10 means millions of users will no longer receive critical security patches, leaving their systems vulnerable to new threats.
  • High volume of attacks: Kaspersky solutions blocked over 700,000 exploits targeting Indian organizations in the first half of 2025, averaging more than 4,000 per day

Attackers increasingly use methods to escalate privileges and exploit weaknesses in digital systems. As the number of vulnerabilities continues to grow, it is very important to constantly prioritize patching known vulnerabilities and use software that can mitigate post-exploitation actions. CISOs should counter the consequences of exploitation by searching for and neutralizing command and control implants that can be used by attackers on a compromised system,” says Alexander Kolesnikov, a security expert at Kaspersky.

What Businesses can do to remain Secure from Cyber threats when systems are unpatched?

For legacy systems and applications there is a lack ongoing vendor support, leaving remote code execution vulnerabilities open for exploitation. These attacks enable full system control with little user interaction.

How to Fix:

Apply host-based intrusion prevention and patch virtualization and replace or containerize legacy apps. It is important to isolate critical workloads in secure enclaves as being in legacy catagory they are prone to any kind of cyber threats and intrusion.

Follow more below recommendations

Conduct 24/7 monitoring of your infrastructure, focusing on perimeter defenses and using tools that can detect and block malicious software.

  • Utilize solutions for vulnerability assessment, patch management
  • Prioritize defense strategies & threat detection like phishing emails and web threats
  • Deploy comprehensive cybersecurity solutions that include incident response, employee training, and access to updated threat intelligence.
  • Implement a robust patch management process

Shai-Hulud NPM Supply Chain Attack Expands to 470+ Packages 

Summary: A large-scale malicious campaign, nicknamed the Shai-Hulud attack, has impacted the npm ecosystem with over 500 trojanized packages, including those packages maintained by CrowdStrike. The attack originated from a sophisticated phishing campaign that exploited the fundamental trust relationships within the npm ecosystem. 

The JavaScript ecosystem is under a massive threat following a major supply chain attack. Hence, millions of crypto users and developers are now at risk. With more than a billion of these packages downloaded already, thousands of blockchain wallets and applications could be suffer varying exploits.

  • Malicious NPM updates spread malware that steals and replaces crypto addresses.
  • Developers encouraged developer to cease on-chain operation and inspect HD wallets thoroughly.

The attackers injected malicious scripts that

  • Run secret-scanning tools on developer systems, 
  • Steal GitHub, npm and cloud credentials, 
  • Insert persistent GitHub Actions workflows for long-term access, and 
  • Exfiltrate sensitive data to attacker-controlled endpoints. 

This attack is ongoing and all users of npm packages should take immediate steps to secure tokens, audit their environments and verify package integrity. 

Issue Details

VoidProxy PhaaS Uses MFA Bypass, Hijacking Google & Microsoft Logins

Security Advisory

Security researchers from Okta have uncovered a stealthy and sophisticated Phishing-as-a-Service (PhaaS) framework known as VoidProxy.

This has been used to hijack Microsoft, Google and even integrated SSO accounts protected by providers like Okta. Unlike traditional phishing kits, VoidProxy employs Adversary-in-the-Middle (AiTM) tactics to capture real-time credentials, MFA tokens and bypassing several standard authentication protections.

VoidProxy’s infrastructure leverages disposable domains, Cloudflare protections, dynamic DNS which all of mimicking as legitimate enterprise setups becoming extremely difficult to detect, analyze. The attackers are running phishing campaigns with little technical effort, enabling wide-scale compromises that lead to email compromise, fraud and data breaches.

Its attack chain is built to evade modern email security, identity defenses, and analysis tools by leveraging the following:

  • CAPTCHA Filtering: Victims are first shown a CAPTCHA challenge before any phishing content loads. This helps block bots and automated security scanners.
  • Cloudflare Workers: Used to deliver customized phishing pages and smartly direct traffic to the attacker’s backend servers.
  • URL Redirection Chains: The phishing links in emails go through several redirects (often using shortened URLs) before landing on fake login pages. This helps bypass spam filters and security tools.
  • Dynamic DNS: These services let attackers quickly create domain names that point to specific IP addresses, making their infrastructure flexible and harder to track.    

Once a user enters their credentials and MFA tokens, the session is hijacked via a reverse proxy server, allowing the attacker to immediately access the legitimate account.

Here are some shortened url links

Attack Flow

StepDescription
1. DeliveryPhishing emails are sent from compromised accounts on email delivery services (like Postmarkapp or Constant Contact) increasing trust and shortening URL services for bypassing spam filters.
2. Redirecting & FilterClicking the phishing link redirects victims through several short URLs and presents a Cloudflare captcha to ensure human interaction.
3. PhishingVictims land on a fake Microsoft or Google login page using realistic subdomain patterns like “login.<phishing_domain>.<.com/.io>”. Additionally, integrated SSO accounts are redirected to additional fake SSO pages mimicking the login flows.
4. AiTM Session HijackThe backend proxy captures credentials, MFA tokens and session cookies, allowing attackers full account access.
5. ExfiltrationSession cookies and credentials are routed to the attacker’s admin panel in real-time. Integration with bots or webhooks enables instant alerts to the attackers.

Why It’s Effective

AiTM Infrastructure: Unlike static phishing kits, VoidProxy runs a live proxy in the middle of the authentication flow, stealing session tokens or mfa token immediately after login.

CAPTCHA & Cloudflare Layers: These challenges ensure only real human victims reach the phishing payload, filtering out scanners and sandboxes.

Integrated SSO Targeting: Accounts using Okta or other SSO providers are redirected to accurate second-stage phishing pages, increasing the likelihood of a full compromise.

Recommendations:

Here are some recommendations below

  • Harden the authentication by bind sessions to IP addresses (IP Session Binding) to block cookie replay attacks.
  • Block access from rarely used IP ranges or unmanaged devices.
  • Provide user awareness training to help recognize phishing links, suspicious email senders and fake login prompts.
  • Keep monitoring for any indications of suspicious activities.

Conclusion
VoidProxy’s layered architecture, real-time session hijacking and deep evasion mechanisms make it a potential threat even for environments with multi-factor authentication in place. We require a shift from traditional phishing detection toward real-time risk-based access controls, strong authenticators and persistent user education.

Vulnerability NameCVE IDProduct AffectedSeverityFixed Version
  Google Chromium Mojo Sandbox Escape Vulnerability  CVE-2025-2783  Google Chrome  High  134.0.6998.117/.118

Technical Summary

This high-severity vulnerability found in the Mojo framework of Chromium-based browsers including Google Chrome, Microsoft Edge, and Opera, Brave etc. The vulnerability originates from a logic error that results in an incorrect handle being provided under certain conditions. This flaw allows attackers to bypass Chrome’s sandbox protections and potentially execute arbitrary code on the affected system.

Security researchers from Kaspersky discovered this zero-day vulnerability as part of an advanced cyber-espionage campaign dubbed “Operation ForumTroll.” The attack campaign targeted media outlets, educational institutions, and government organizations in Russia through highly personalized phishing emails.

The exploit chain is particularly dangerous because it requires minimal user interaction. Victims only need to click on a malicious link in a phishing email, after which the attack executes automatically without any additional action from the user. Once triggered, the exploit allows attackers to escape Chrome’s sandbox environment, leading to remote code execution and possible system compromise.
