In April 2025, the Global Threat Hunting system of NSFOCUS Fuying Lab detected a significant increase in the activity of a new Botnet Trojan developed based on Go language. Given that many of its built-in DDoS attack methods are HTTP-based, Fuying Lab named it HTTPBot. The HTTPBot Botnet family first came into our monitoring scope in August 2024. Over the past few months, it has expanded aggressively, continuously leveraging infected devices to launch external attacks. Monitoring data indicates that its attack targets are primarily concentrated in the domestic gaming industry. Additionally, some technology companies and educational institutions have also been affected. The attack of this Botnet family is highly targeted, with attackers employing a periodical and multi-stage attack strategy to conduct continuous saturation attacks on selected targets.
In terms of technical implementation, the HTTPBot Botnet Trojan uses an “attack ID” to precisely initiate and terminate the attack process. It also incorporates a variety of innovative DDoS attack methods. By employing highly simulated HTTP Flood attacks and dynamic feature obfuscation techniques, it circumvents traditional rule-based detection mechanisms, including but not limited to the following detection bypass mechanisms:
Malicious actors are using SourceForge to distribute a miner and the ClipBanker Trojan while utilizing unconventional persistence techniques.
Kaspersky experts discover iOS and Android apps infected with the SparkCat crypto stealer in Google Play and the App Store. It steals crypto wallet data using an OCR model.

Antivirus firm Dr.Web has flagged a type of Android malware known as Android.Vo1d that has infected about 1.3 million TV boxes across 197 countries.
The malware effectively enables a backdoor into the TV box's system that allows an attacker to download and install malicious third-party software. The R4 TV box model running Android 7.1.2, a TV Box running Android 12.1, and the KJ-SMART4KVIP TV box running Android 10.1 were the types of devices reportedly impacted.
Kaspersky experts discovered a macOS version of the HZ Rat backdoor, which collects user data from WeChat and DingTalk messengers.

Group-IB, a leading creator of cybersecurity technologies to investigate, prevent, and fight digital crime, has uncovered a new iOS Trojan designed to steal users’ facial recognition data, identity documents, and intercept SMS. The Trojan, dubbed GoldPickaxe.iOS by Group-IB’s Threat Intelligence unit, has been attributed to a Chinese-speaking threat actor codenamed GoldFactory, responsible for developing a suite of highly sophisticated banking Trojans that also includes the earlier discovered GoldDigger and newly identified GoldDiggerPlus, GoldKefu, and GoldPickaxe for Android. To exploit the stolen biometric data, the threat actor utilizes AI face-swapping services to create deepfakes by replacing their faces with those of the victims. This method could be used by cybercriminals to gain unauthorized access to the victim’s banking account – a new fraud technique, previously unseen by Group-IB researchers. The GoldFactory Trojans target the Asia-Pacific region, specifically — Thailand and Vietnam impersonating local banks and government organizations.
Group-IB’s discovery also marks a rare instance of malware targeting Apple’s mobile operating system. The detailed technical description of the Trojans, analysis of their technical capabilities, and the list of relevant indicators of compromise can be found in Group-IB’s latest blog post.

Illegally distributed software historically has served as a way to sneak malware onto victims’ devices. Oftentimes, users are not willing to pay for software tools they need, so they go searching the Web for a “free lunch”. They are an excellent target for cybercriminals who realize that an individual looking for a cracked app will be willing to download an installer from a questionable website and disable security on their machine, and so they will be fairly easy to trick into installing malware as well.
