Latest coverage for Backdoor

TrendAI™ Research breaks down Quasar Linux (QLNX), a previously undocumented sophisticated Linux RAT with low detection rates. In this blog, we examine a full-featured Linux threat incorporating a rootkit, a PAM backdoor, credential harvesting, and more, revealing how this malware enables stealthy access, persistence, and potential supply-chain attacks.

TeamPCP orchestrated one of the most sophisticated multi-ecosystem supply chain campaigns publicly documented to date that cascaded through developer tooling and compromised LiteLLM, exposing how AI proxy services that concentrate API keys and cloud credentials become high-value collateral when supply chain attacks compromise upstream dependencies.

The BoryptGrab campaign uses fake SEO‑optimized GitHub repositories and deceptive download pages to distribute a data‑stealing malware family that delivers multiple payloads, including a reverse SSH backdoor, to Windows users.

In this blog entry, Trend™ Research provides a comprehensive breakdown of GhostPenguin, a previously undocumented Linux backdoor with low detection rates that was discovered through AI-powered threat hunting and in-depth malware analysis.

In this post of THE AI BREACH, learn how your Chatbot can become a backdoor.

A controller linked to BPF backdoor can open a reverse shell, enabling deeper infiltration into compromised networks. Recent attacks have been observed targeting the telecommunications, finance, and retail sectors across South Korea, Hong Kong, Myanmar, Malaysia, and Egypt.

Trend Micro’s monitoring of the MOONSHINE exploit kit revealed how it’s used by the threat actor Earth Minotaur to exploit Android messaging app vulnerabilities and install the DarkNimbus backdoor for surveillance.

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.

While monitoring Earth Lusca, we discovered the threat group’s use of KTLVdoor, a highly obfuscated multiplatform backdoor, as part of a large-scale attack campaign.

Trend Micro discovered that old Atlassian Confluence versions that were affected by CVE-2023-22527 are being exploited using a new in-memory fileless backdoor.

This blog entry provides an analysis of the Noodle RAT backdoor, which is likely being used by multiple Chinese-speaking groups engaged in espionage and other types of cybercrime.

Almost a year after Void Rabisu shifted its targeting from opportunistic ransomware attacks with an emphasis on cyberespionage, the threat actor is still developing its main malware, the ROMCOM backdoor.

We observed and tracked the advanced persistent threat (APT) APT34 group with a new malware variant accompanying a phishing attack comparatively similar to the SideTwist backdoor malware. Following the campaign, the group abused a fake license registration form of an African government agency to target a victim in Saudi Arabia.

While monitoring Earth Lusca, we discovered an intriguing, encrypted file on the threat actor's server — a Linux-based malware, which appears to originate from the open-source Windows backdoor Trochilus, which we've dubbed SprySOCKS due to its swift behavior and SOCKS implementation

An analysis of advanced persistent threat (APT) group Red Menshen’s different variants of backdoor BPFDoor as it evolves since it was first documented in 2021.

Void Rabisu, a malicious actor believed to be associated with the RomCom backdoor, was thought to be driven by financial gain because of its ransomware attacks. But in this blog entry, we discuss how the use of the RomCom backdoor in recent attacks shows how Void Rabisu's motives seem to have changed since at least October 2022.

We discovered a new backdoor which we have attributed to the advanced persistent threat actor known as Earth Kitsune, which we have covered before. Since 2019, Earth Kitsune has been distributing variants of self-developed backdoors to targets, primarily individuals who are interested in North Korea.

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 March 2021, we investigated a backdoor with a unique modular architecture and called it BumbleBee due to a string embedded in the malware. However, in our recent investigations, we have discovered a controller application that expands its capabilities.
