Latest coverage for Infection

Our research on Void Dokkaebi’s operations uncovered a campaign that turns infected developer repositories into malware delivery channels. By spreading through trusted workflows, organizational codebases, and open-source projects, the threat can scale from a single compromise to a broader supply chain risk.

This blog entry provides an in-depth analysis of the multistage delivery of the Evelyn information stealer, which was used in a campaign targeting software developers.

Through AI-driven code conversion and a layered infection chain involving different file formats and scripting languages, the threat actors behind Water Saci are quickly upgrading their malware delivery and propagation methods across WhatsApp in Brazil.

Continuous investigation on the Water Saci campaign reveals innovative email-based C&C system, multi-vector persistence, and real-time command capabilities that allow attackers to orchestrate coordinated botnet operations, gather detailed campaign intelligence, and dynamically control malware activity across multiple infected machines.

Trend Research discusses the delivery methods, custom payloads, and techniques used by Water Gamayun, the suspected Russian threat actor abusing a zero-day vulnerability in the Microsoft Management Console framework (CVE-2025-26633) to execute malicious code on infected machines.

Trend Micro MDR (Managed Detection and Response) team promptly mitigated a more_eggs infection. Using Vision One, MDR illustrated how Custom Filters/Models and Security Playbook can be used to automate the response to more_eggs and similar threats.

We analyze the multi-stage loading technique used by Water Sigbin to deliver the PureCrypter loader and XMRIG crypto miner.

This blog entry delves into MxDR's unraveling of the AsyncRAT infection chain across multiple cases, shedding light on the misuse of aspnet_compiler.exe, a legitimate Microsoft process originally designed for precompiling ASP.NET web applications.

This entry delves into threat actors' intricate methods to implant malicious payloads within seemingly legitimate applications and codebases.

In this blog entry, we will provide details on Rhysida, including its targets and what we know about its infection chain.

We found that malicious actors used malvertising to distribute malware via cloned webpages of legitimate organizations. The distribution involved a webpage of the well-known application WinSCP, an open-source Windows application for file transfer. We were able to identify that this activity led to a BlackCat (aka ALPHV) infection, and actors also used SpyBoy, a terminator that tampers with protection provided by agents.

Water Orthrus has been active recently with two new campaigns. CopperStealth uses a rootkit to install malware on infected systems, while CopperPhish steals credit card information. This blog will provide the structure of the campaign and how they work.

After months of dormancy, Earth Longzhi, a subgroup of advanced persistent threat (APT) group APT41, has reemerged using new techniques in its infection routine. This blog entry forewarns readers of Earth Longzhi’s resilience as a noteworthy threat.

We analyze an infection campaign targeting organizations in the Middle East for cyberespionage in December 2022 using a new backdoor malware. The campaign abuses legitimate but compromised email accounts to send stolen data to external mail accounts controlled by the attackers.

In this blog entry, we’d like to highlight our findings on Vice Society, which includes an end-to-end infection diagram that we were able to create using Trend Micro internal telemetry.

We analyzed the infection routine used in recent Gootkit loader attacks on the Australian healthcare industry and found that Gootkit leveraged SEO poisoning for its initial access and abused legitimate tools like VLC Media Player.

This report examines the infection chain and the pieces of malware used by malicious actors in supply-chain attacks that leveraged trojanized installers of chat-based customer engagement platforms.

We break down the cyberespionage activities of advanced persistent threat (APT) group Earth Preta, observed in large-scale attack deployments that began in March. We also show the infection routines of the malware families they use to infect multiple sectors worldwide: TONEINS, TONESHELL, and PUBLOAD.

Open-source applications are a practical way to save money while keeping up with your productivity. However, this can be abused by threat actors to steal your data. Find out how one app was used to gather information of Apple users.

We analyzed cases of a Log4Shell vulnerability being exploited in certain versions of the software VMware Horizon. Many of these attacks resulted in data being exfiltrated from the infected systems. However, we also found that some of the victims were infected with ransomware days after the data exfiltration.
