🚨 Q1 2025 Was a Wake-Up Call

The first quarter of 2025 saw cybercriminals ramp up their tactics across the board — from ransomware and cryptominers to macOS malware and IoT device exploits. Drawing on detailed telemetry from Kaspersky, we break down the most urgent threats and what they mean for business leaders, IT teams, and cybersecurity professionals.

📊 Global Threat Landscape: Q1 in Numbers

  • 629+ million attacks blocked by Kaspersky products
  • 88 million malicious URLs detected
  • 21.5 million+ harmful files intercepted
  • 11,733 new ransomware variants emerged
  • 85,000+ users hit by ransomware
  • 315,000+ users faced miner-related threats

🔐 Ransomware: Evolving Faster Than Defenses

Three ransomware gangs dominated in Q1:

  • RansomHub – 11.03% of public victim disclosures
  • Akira – 10.89%
  • Clop – 10.69%

📌 Notable Law Enforcement Wins

  • 8Base/Phobos takedown – Arrest of four members across Thailand, linked to 1,000+ attacks and $16M in extortion
  • LockBit developer extradited – Suspected actor brought to the US from Israel over $230K in ransom development work

🧰 Techniques Used by Attackers

  • BYOVD: Exploited vulnerabilities in Paragon Partition Manager for SYSTEM-level access
  • Akira: Used a vulnerable Linux webcam to run ransomware and bypass EDR
  • HellCat: Stole Jira credentials using infostealers like Lumma

🏆 Top 3 Ransomware Families by Detection

  1. Trojan-Ransom.Win32.Gen – 25.1%
  2. WannaCry – 8.19%
  3. Trojan-Ransom.Win32.Encoder – 6.7%

🪙 Cryptominers: Silent but Widespread

  • 5,467 new miner variants detected
  • 315,701 users affected

Top countries by infection rate included Senegal, Kazakhstan, Panama, and Belarus.

🍏 macOS: The Malware Front No One Talks About

Contrary to common belief, macOS is not immune. The first quarter saw major developments:

  • ReaderUpdate (Go variant): Loader used to push adware or more serious payloads
  • Ferret family: Spread via fake job interviews, deploying backdoors and stealers
  • Amos stealer: The most aggressive macOS Trojan in Q1 — targeting passwords, wallets, and browser data

📈 Top macOS Threats

  • Trojan.OSX.Agent.gen
  • Amos variants
  • Reverse proxies and fake system tools

📡 IoT Under Siege

IoT devices remained a prime target for botnets, crypto miners, and initial access brokers.

  • Mirai variants: Continued dominance in IoT attacks
  • NyaDrop: Accounted for 19% of IoT malware
  • BitcoinMiner: Still prevalent across compromised smart devices

🌍 IoT Attack Origins Shifting

Telnet and SSH-based attacks increased, with notable spikes from:

  • Brazil: 12.03% of Telnet-based attacks
  • Nigeria: Now at 3% of global Telnet-based attacks

🌐 Web-Based Attacks: Millions at Risk

629M+ web threats were blocked globally. Most came from infected legitimate websites, redirector scripts, or phishing kits.

🧨 Highest Risk Countries (Web Infections)

  1. North Macedonia – 10.17%
  2. Albania – 9.96%
  3. Algeria – 9.92%

💾 Local Threats: USBs and File-Borne Attacks

File Anti-Virus detected 21.5M+ objects. These include trojans on USB drives, infected installers, and malware hidden in compressed files.

🌍 Most Affected Regions (Local Infections)

  • Turkmenistan – 47.4%
  • Tajikistan – 37.2%
  • Afghanistan – 36.9%

🧠 What Your Business Should Be Doing Now

  • Patch legacy systems and connected devices
  • Implement a strong EDR solution
  • Secure IoT and isolate high-risk segments
  • Train staff on phishing, social engineering, and credential hygiene
  • Establish a ransomware playbook with recovery options

🔐 Final Word

Attackers are evolving — and fast. From endpoint bypasses to IoT botnets, no layer of your tech stack is immune. What used to be “big company” problems are now hitting SMBs and startups with equal force.

If you’re not actively monitoring, governing, and preparing for the new wave of threats — you’re operating on borrowed time.
