Inside the World of Malware: A Global Journey Through Cyber Threats

Welcome, seekers of cyber wisdom, to Inside the World of Malware. In this journey, we’ll explore how malicious software operates, uncover its various forms, and witness its real-world consequences.

The Anatomy of Malware

Malware—short for malicious software—is an intrusive software designed to infiltrate, damage, or gain unauthorized access to computer systems. Within this broad category, several distinct types emerge:

Malware in the Wild—Real-World Catastrophes

TAG-110

A Russia-aligned threat group known as TAG-110 recently launched a spear-phishing campaign targeting Tajikistan using macro-enabled Word templates (.dotm). These malicious documents mimic official government files and, once opened, execute VBA macros that embed themselves in the Word startup folder for automatic execution on future launches. This shift in tactic marks a departure from their previous use of HTA-based malware (HATVIBE), highlighting an evolution in persistence techniques. The campaign likely aims to gather intelligence from government, educational, and research institutions, consistent with TAG-110’s espionage history.

ILOVEYOU Worm

The ILOVEYOU virus, released on May 4, 2000, is one of the most destructive computer viruses ever, infecting millions of systems within hours. It spread via email as a fake "love letter" attachment, exploiting Microsoft Outlook to replicate itself rapidly. Once opened, it would send copies to all contacts, causing massive disruptions across governments and corporations. The virus caused $3–15 billion in damages, mainly from cleanup and recovery efforts. Its impact led to global changes in cybersecurity practices, public awareness, and legal reforms in the Philippines, where it originated.

SpyMax

A new variant of the Android-based Remote Access Trojan (RAT) SpyMax is being spread through social engineering attacks, particularly via fake apps like Telegram or wedding invitation apps. Cybercriminals are distributing these malicious APKs through messaging platforms such as WhatsApp and phishing links. Once installed, the fake app tricks users into granting dangerous permissions that give attackers full control over the device. The malware then steals sensitive data such as contacts, SMS, OTPs, and notifications, which it sends to a remote server. This campaign relies heavily on user trust and deception to bypass security and infect mobile devices.

Graphite

In early 2025, WhatsApp revealed that nearly 100 journalists and civil society members were targeted by Graphite, a powerful spyware developed by Israeli firm Paragon Solutions. The spyware was delivered via malicious PDF files in group chats and used zero-click techniques, meaning users were infected without clicking anything. Once installed, Graphite granted attackers full access to devices, including encrypted messages from apps like WhatsApp and Signal. This covert surveillance campaign fits the definition of spyware, as it secretly monitored and reported sensitive user data to remote operators. WhatsApp has since disrupted the campaign and is notifying affected users.

Kaleidoscope

Kaleidoscope is a 2025 Android adware campaign that creates two versions of the same app: a harmless “decoy” on Google Play and an “evil twin” distributed through third-party app stores. The malicious version generates intrusive full-screen ads without user interaction, degrading device performance and fraudulently earning ad revenue. It evolved from a previous adware scheme called Konfety and now uses disguised SDKs like Raccoon and Adsclub. The adware is most prevalent in regions like India, Türkiye, Egypt, and Latin America, where third-party app stores are popular. The operation tricks advertisers by serving fake ad impressions under the name of the legitimate app.

SafePay Ransomware Attack

In July 2025, tech giant Ingram Micro suffered a major ransomware attack by the SafePay cyber gang, causing widespread system outages and halting operations across its global network. The attack forced the company to take systems offline, disrupted online ordering, and triggered an ongoing investigation involving law enforcement and cyber forensics teams. SafePay, known for its double extortion tactics, typically encrypts systems and steals data, threatening public leaks if ransoms are not paid. While Ingram Micro hasn’t confirmed data theft, experts warn it may soon appear on SafePay’s leak site. This incident highlights the growing threat posed by centralized ransomware groups targeting major corporations worldwide.

PowerShell-based Remcos RAT attack

In May 2025, researchers at Qualys uncovered a fileless malware campaign that used a PowerShell-based shellcode loader to execute the Remcos RAT entirely in memory. Delivered via malicious LNK files disguised as Office documents, the malware used Windows tools like mshta.exe and PowerShell to load code directly into RAM without writing executable files to disk. It leveraged advanced techniques such as dynamic API resolution, PEB walking, and process hollowing, making it extremely hard to detect with traditional antivirus tools. Once active, Remcos provided full remote access, enabling spying, keylogging, and data theft.

The Evolving Malware Battlefield

While historic incidents like ILOVEYOU and recent cases such as SafePay ransomware highlight malware’s destructive potential, the threat landscape is constantly shifting. Here are details of some of the malware families that are currently making the biggest impact and how they’re breaching systems.

For a long time now, SocGholish leads the pack, responsible for 48% of detections. Spread via malicious browser update prompts on compromised websites, SocGholish often acts as a gateway to more dangerous payloads like NetSupport, AsyncRAT, and even ransomware. Other prevalent threats include:

• ZPHP – Downloader delivering tools like Lumma Stealer.

• CoinMiner – Cryptocurrency miner spreading via WMI and malspam.

• TeleGrab – Telegram-specific infostealer that hijacks chats and steals history.

• VenomRAT – Open-source Remote Access Trojan with keylogging and data exfiltration features.

• Agent Tesla – A long-running .NET-based RAT sold as malware-as-a-service, used for stealing data, keylogging, and screenshots, often delivered via phishing emails.

• Arechclient2 – Remote access tool (RAT) that also contains information stealer capabilities

• LandUpdate808 – A JavaScript downloader spread via fake browser updates, installing tools like NetSupport RAT after execution.

• DarkGate – A multifunctional, evasive malware capable of data theft, remote access, and persistence, distributed through phishing and other deceptive methods.

• Ratenjay – A RAT dropped by other malware, enabling remote command execution and keylogging.

Initial Infection Vectors observed in 2025 are:

• Malvertisement – The leading vector, used by SocGholish, ZPHP, and LandUpdate808.

• Malspam – Unsolicited emails carrying malicious attachments or links, common for Agent Tesla.

• Dropped – Malware installed by other malware or via exploit kits.

• Multiple vectors – Sophisticated campaigns using two or more delivery methods.

In addition to this, several notorious malware families continue to evolve:

• Lumma Stealer – Sold on the Dark Web since 2022, capable of extracting credentials, crypto-wallet data, and installing other malware. Often spread via fake CAPTCHA pages and phishing.

• XWorm – Remote access tool with spying, clipboard hijacking, and credential theft capabilities; frequently delivered via phishing emails with malicious archives.

• AsyncRAT – RAT known for screen recording, keylogging, and persistence; often disguised as pirated software or dropped by other malware.

• Remcos RAT – Initially marketed as legitimate software, now a common espionage tool using VBScript and PowerShell-based attacks.

• LockBit Ransomware – One of the most active ransomware families, leveraging a Ransomware-as-a-Service (RaaS) model and responsible for high-profile global attacks.

Why this matters:
This real-time snapshot shows how old attack techniques keep resurfacing in new forms, making layered defenses, user education, and rapid incident response more critical than ever.
