New Android Malware 'FluHorse' Targeting East Asian Markets with Deceptive Tactics

-

 

Various sectors in East Asian markets have been subjected to a new email phishing campaign that distributes a previously undocumented strain of Android malware called FluHorse that abuses the Flutter software development framework.

"The malware features several malicious Android applications that mimic legitimate applications, most of which have more than 1,000,000 installs," Check Point said in a technical report. "These malicious apps steal the victims' credentials and two-factor authentication (2FA) codes."

The malicious apps have been found to imitate apps like ETC and VPBank Neo, which are used in Taiwan and Vietnam. Evidence gathered so far shows that the activity has been active since at least May 2022.

The threat actors also abuse their access to SMS messages to intercept all incoming 2FA codes and redirect them to the command-and-control server.

Interestingly, the malicious functionality is implemented with Flutter, an open source UI software development kit that can be used to develop cross-platform apps from a single codebase.

While threat actors are known to use a variety of tricks like evasion techniques, obfuscation, and long delays before execution to resist analysis and get around virtual environments, the use of Flutter marks a new level of sophistication.

"The malware developers did not put much effort into the programming, instead relying on Flutter as a developing platform," the researchers concluded.

"This approach allowed them to create dangerous and mostly undetected malicious applications. One of the benefits of using Flutter is that its hard-to-analyze nature renders many contemporary security solutions worthless."

The Hidden Lag Killing Your SIEM Efficiency

-

  If your security tools feel slower than they should, you’re not imagining it. Many IT teams blame their sluggish SIEM performance on query complexity or alert volume. But sometimes the real issue is much simpler: oversized input files quietly dragging your system down. Think about the last time you had to sift through a bloated PDF or an unoptimised log dump. Every unnecessary megabyte adds strain. Every redundant line eats up cycles. Your SIEM doesn’t just react to threats—it processes all incoming data, relevant or not. When it starts lagging, detection gets delayed, triage slows, and in the high-stakes world of threat response, even seconds count. We often focus on analytics and rule tuning, but upstream efficiency—what you feed into your system—deserves just as much attention. This article looks at how optimising your inputs unlocks downstream performance. Why Oversized Files Clog the Pipeline As data volumes grow, organisations face esca lating  data storage costs ,...

Critical Vulnerability in Veeam Backup & Replication Exposes Enterprises to Remote Code Execution By : Rei Ibraima A newly discovered critical vulnerability in Veeam’s Backup & Replication software, designated as CVE-2025-23120, poses a significant security risk to enterprise environments. The flaw allows authenticated domain users to execute arbitrary code remotely, potentially leading to full compromise of backup infrastructures. About CVE-2025-23120 The vulnerability arises from an insecure deserialization issue within Veeam Backup & Replication components—particularly in the .NET classes Veeam.Backup.EsxManager.xmlFrameworkDs and Veeam.Backup.Core.BackupSummary. Improper input validation in these components allows attackers to inject malicious serialized objects that are executed on the server side, resulting in Remote Code Execution (RCE). This issue affects systems where Veeam Backup & Replication is deployed in a domain-joined configuration, which—while common—is...

The China-linked cyber espionage group tracked as Lotus Panda has been attributed to a campaign that compromised multiple organizations in an unnamed Southeast Asian country between August 2024 and February 2025. "Targets included a government ministry, an air traffic control organization, a telecoms operator, and a construction company," the Symantec Threat Hunter Team said in a new report shared with The Hacker News. "The attacks involved the use of multiple new custom tools, including loaders, credential stealers, and a reverse SSH tool." The intrusion set is also said to have targeted a news agency located in another country in Southeast Asia and an air freight organization located in another neighboring country. The threat cluster, per Broadcom's cybersecurity division, is assessed to be a continuation of a campaign that was disclosed by the company in December 2024 as a high-profile organization in Southeast Asia since at least October 2023. ...
