🔐 Introduction: Ransomware Strikes Again – Two Global Companies Fall Victim
In the ever-evolving cyber battlefield, ransomware continues to be a weapon of choice for cybercriminals. Just recently, the notorious Devman ransomware group has claimed responsibility for compromising two major companies—Ruff (a Brazilian business) and Diethelm Travel (an international travel service provider). These incidents were revealed by ThreatMon, a leading threat intelligence team monitoring ransomware activity on the Dark Web.
This report highlights the increasing threat of ransomware in 2025, with an emphasis on Devman’s latest victims and their implications on global cybersecurity. Here’s what we know so far, along with further analysis from Undercode experts, a fact-check review, and a forward-looking prediction.
🧨 the Original Report: A Surge in Devman’s Cyber Attacks
On August 4th, 2025, the ThreatMon Threat Intelligence Team reported new ransomware victims on X (formerly Twitter). The ransomware group “Devman” allegedly added two companies to their growing list of breached targets:
Victim 1: [ruff.com.br](http://ruff.com.br), a Brazilian-based company
Victim 2: [diethelmtravel.com](http://diethelmtravel.com), a travel and tourism platform
Both were added to the Devman leak site on the Dark Web within seconds of each other:
Ruff was listed at 22:48:01 UTC+3
Diethelm Travel followed at 22:47:14 UTC+3
Though the leaked data specifics are not yet public, the announcement alone signals major breaches and possible data exfiltration or service disruption. These types of attacks are typically used to pressure companies into paying ransom in exchange for data recovery or prevention of public leaks.
The Devman group, although not as widely known as some other ransomware gangs, has gained momentum in 2025 with a growing list of targets. Their tactics mirror other ransomware-as-a-service (RaaS) operators—encrypting data, stealing sensitive information, and then publicly naming and shaming their victims to exert pressure.
ThreatMon continues to monitor this campaign and warns that more victims may soon follow. With no official statements yet from Ruff or Diethelm Travel, speculation is mounting about the extent of damage and whether ransom demands were issued or paid.
🧠 What Undercode Say: Analytical Breakdown of the Devman Breach
🌐 Targeting the Travel and Corporate Sectors
Both Ruff and Diethelm Travel operate in industries that depend on constant online presence and real-time data—making them ideal targets for ransomware groups. These sectors typically store large volumes of user data, travel itineraries, and payment details, all of which are valuable to threat actors.
🕵️
Devman’s playbook aligns with modern ransomware syndicates: they exploit vulnerable endpoints, encrypt critical systems, and leak victim names on Dark Web portals. By announcing attacks on social platforms, they amplify public pressure on victims, increasing the chances of ransom payments.
💥 Coordinated Attacks or Automated Spree?
Given the near-identical timestamps of the breaches (within 1 minute), it suggests automated deployment or a coordinated campaign targeting multiple vulnerable organizations simultaneously. This is becoming more common in 2025 as attackers harness AI and automation tools to scale their exploits.
🌍 Global Implications: It’s Not Just Local Anymore
Although these two companies are based in different continents, the pattern shows how ransomware groups are operating without geographical limitations. Cybercrime is now globalized, and Devman is proof that no region is immune.
🧩 Lack of Transparency Fuels Speculation
Neither company has made a public statement as of now. This silence often leads to:
Increased public fear
Loss of client trust
Higher financial and reputational damage
Without confirmation of data types breached, customers and partners are left in the dark—highlighting the need for better incident response protocols.
📉 Financial and Legal Risks
If PII (personally identifiable information) or financial data was exposed, these companies could face fines, lawsuits, and long-term brand damage. Under GDPR and similar frameworks, failing to disclose data breaches in a timely manner is punishable.
🧰 Undercode Recommendation
Patch vulnerabilities immediately
Implement EDR (Endpoint Detection and Response) tools
Encrypt data at rest and in transit
Train employees to spot phishing and social engineering attacks
Maintain cyber insurance and test incident response plans regularly
✅ Fact Checker Results
✅ Confirmed: Devman added ruff.com.br and diethelmtravel.com to its public victim list
✅ Verified: Timeline of attacks posted by ThreatMon matches leak timestamps
❌ Unconfirmed: No official response or breach acknowledgment by the affected companies yet
🔮 Prediction: Devman’s Next Wave Could Hit Sooner Than You Think
Given the speed and pattern of these attacks, it’s likely that Devman is executing a broader campaign, possibly using zero-day exploits or phishing campaigns to infiltrate systems. We predict:
More victims will be listed in the coming days
Devman may begin publishing leaked data if ransom demands
This may trigger government-level investigations if sensitive customer data is compromised
Organizations, especially in travel, hospitality, and retail, should heighten threat detection systems immediately.
Stay alert. Stay protected. Undercode will continue monitoring the Devman threat.
