🚀 CloudSEK has raised $19M Series B1 Round – Powering the Future of Predictive Cybersecurity
Read More
In July 2025, CloudSEK analyzed how misinformation and recycled breach data—from forums, media, and researchers—flood threat intel teams with false alarms. High-profile cases like the “16 Billion Credential Leak” and ICMR breach were inflated using old or fake data. This noise wastes up to 25% of security teams’ time. The report offers a clear framework to verify breach legitimacy, reduce alert fatigue, and focus on real, high-priority cyber threats.
Proactively monitor and defend your organization against threats from the dark web with CloudSEK XVigil.
Schedule a DemoIt’s 9 AM on a Monday. Your threat intel dashboard lights up. Headlines flood your feed: “16 Billion Credential Leak Shocks the Internet!” Is this a critical threat or just noise? Cybersecurity professionals, executives, and researchers face this flood of “urgent” alerts daily, often chasing distractions instead of real threats. Noise isn’t just from underground forums it can stem from marketing campaigns, researchers exaggerating findings, or social media amplifying unverified claims. This report unravels the ecosystem fueling this noise and offers a framework to prioritize genuine threats.
What is "Noise"?
Noise in threat intelligence refers to overhyped or misleading data misreported as new breaches. The three main types are:
Not all reported breaches are noise, some are genuine and demand urgent action. Distinguishing these saves resources and time for security teams.
Noise often originates in underground forums but is amplified by sensationalized media, marketing-driven reports, or researchers seeking attention. Understanding this ecosystem is key to filtering signals from noise.
The Forum Takedown Effect
When law enforcement shuts down major underground forums, like BreachForums in May 2024, a power vacuum forms. Rival forums compete to attract displaced users by releasing “new” datasets, often recycled breaches offered for free to boost sign-ups. This flood of old data creates noise that spreads beyond forums. In June 2025, French authorities arrested five key BreachForums operators, including “ShinyHunters” and “IntelBroker,” in coordinated raids across Paris, Normandy, and Réunion. These arrests, targeting administrators linked to high-profile data leaks, further disrupted the forum’s operations, intensifying the scramble among rival platforms to fill the void.
Source Credibility and Misinformation
Threat actors build credibility by curating data compilations, but not all sources are reliable. For instance, the Chinese dark web forum Chang’an is known for recycling old data and fabricating breaches with random organization names, creating a unique type of noise. Sensationalized headlines, vendor marketing, or researchers exaggerating findings (e.g., claiming an “184 Million Credential Breach”) further amplify this noise, often lacking context and fueling panic. Assessing the credibility and reliability of the source whether a forum, researcher, or media outlet should be the first question asked to filter noise.
Initial Headline (Oct 2024): “Free.fr Breached – 19.2 Million Customer Records for Sale”
Reality: French ISP Free.fr confirmed a breach affecting 19.2 million accounts. Threat actor “drussellx” offered a 43.6GB dataset on BreachForums, including names, addresses, emails, phone numbers, and 5.11 million IBANs, exfiltrated via a management tool vulnerability on October 17, 2024.No passwords or card details were compromised.
Fallout (2024–2025): The dataset, initially priced at $175,000, was a ruse to extort Free.fr, with no sale occurring. It was reposted on dark web forums and Telegram with inflated claims of “20 million accounts” and fake credentials added to boost value. The repackaged data fueled phishing and fraud, eroding trust and prompting GDPR scrutiny over delayed notifications.
Intel Insight: Low-skill actors can exploit simple vulnerabilities, creating noise via repackaged data. Monitor dark web forums with SOCRadar, verify leaks with HIBP, and fingerprint datasets (e.g., IBANs) to identify fakes.
Initial Headline (Sep 2024): “Boulanger Hacked – 27 Million Records Exposed”
Reality: French retailer Boulanger faced a ransomware attack, exposing 27.5 million data rows (1 million unique records) with emails, names, addresses, phone numbers, and geolocation. Threat actor “horrormar44” sold the 16GB JSON dataset for €2,000 on BreachForums. No payment data was compromised.
Fallout (2024–2025): By April 2025, the dataset was leaked for free on BreachForums, dropping to $2 in forum credits. Reposts with fake payment details and claims of “30 million records” surfaced, inflating the breach’s scope. These fueled phishing campaigns posing as Boulanger promotions, amplifying noise and scam risks.
Intel Insight: Ransomware leaks create noise when freely shared with padded data. Fingerprint unique data (e.g., geolocation) and use HIBP to verify leaks. Monitor dark web forums to detect repackaged dumps.
Initial Headline (Oct 2023): “ICMR Hacked – 850 Million Indian Citizens’ Data Exposed”Reality: The Indian Council of Medical Research (ICMR) confirmed a breach of 81.5 million unique records via a misconfigured API. Threat actor “pwn0001” offered a 90GB dataset on BreachForums with names, Aadhaar numbers, addresses, and health data.
Fallout (2023–2025): Initially sold for $80,000, the dataset was later freely shared on dark web forums and Telegram. Repackaged versions with fake banking details claimed “1 billion records,” inflating the breach’s scope. These fueled phishing and loan scams, triggering lawsuits under India’s DPDPA.
Intel Insight: Unsecured APIs create significant breaches, amplified by repackaged data. Use HIBP and fingerprinting (e.g., Aadhaar numbers) to verify leaks. Monitor dark web forums to track scam campaigns.
Wasted Time and Resources
Chasing false positives creates a significant resource drain, consuming up to 25% of a security team's time. For a mid-sized SOC, this means 100 hours a week are lost investigating non-threats instead of focusing on active dangers like ransomware or insider attacks.
Loss of Trust
Frequent false alarms erode leadership confidence, making them skeptical of genuine incidents. This can delay critical responses to real threats.
Misguided Priorities
Hyped “breaches,” amplified by sensationalized headlines or vendor reports lacking context, shift attention from less sensational but more damaging threats like Business Email Compromise (BEC), social engineering, or insider risks, which often cause greater harm.
The "Is It Real?" Checklist
To spot noisy breaches, ask:
Our external threat monitoring platform, Xvigil, cross-references breach claims against historical data points, reducing false positives . This sharpens focus on high-priority threats.
The cybersecurity world faces a context problem, not just a data breach problem. Noise from underground forums, exaggerated researcher claims, or sensationalized media reports—like those from forums such as Chang’an—fuels panic and wastes resources. By scrutinizing source credibility, de-duplicating data, and using robust filtering systems, security teams can focus on genuine threats. For CEOs, this ensures resources are allocated to strategic priorities, not false alarms. Emerging trends, like AI-generated fake breach data, could amplify noise, making these systems even more critical. Journalists can help by verifying claims with primary sources, reducing public panic.
