North Korean hackers targeted ethnic Koreans in China with a malware disguised as a popular Android mobile game called BirdCall, allowing them to steal personal data from victims.
ScarCruft compromised a video game platform in a supply chain attack, trojanizing its components with a backdoor called BirdCall to target ethnic Koreans residing in China. The attack enabled the threat actors to target both Windows and Android devices, turning it into a multi-platform threat. The campaign targeted sqgame[.]net, a gaming platform used by ethnic Koreans in China, known as a transit point for North Korean defectors. BirdCall has features like screenshot capture, keystroke logging, and data gathering, and relies on legitimate cloud services for command-and-control. The Android variant collects various data and has seen active development.
A North Korean hacking group has targeted a digital gaming platform popular among the Korean ethnic enclave in China, using a sophisticated strategy to infiltrate Android applications. Researchers from Eset discovered that an app on the platform contained a backdoor known as BirdCall, linked to North Korea. The official website for the gaming platform hosted the same suspicious APK file. A second Android file associated with another game on the same site was also found to contain the BirdCall backdoor. This supply-chain attack was attributed to the threat actor ScarCruft (APT37), active in Asia and extending into Europe and the Middle East since late 2024. The hackers likely compromised the web server to recompile original APKs with the backdoor, which can collect sensitive information such as contacts, SMS messages, call logs, documents, media files, and private keys, and can take screenshots and record audio. The malware disguises its command and control traffic among regular internet traffic, primarily using Zoho WorkDrive for operations.
Cybersecurity researchers at Wiz’s ZeroDay.Cloud event in London exploited two significant vulnerabilities in PostgreSQL, tracked as CVE-2026-2005 and CVE-2026-2006, which were disclosed on May 4, 2026. The vulnerabilities were found in the pgcrypto extension, affecting public-key decryption and symmetric decryption functions. CVE-2026-2005 allows privilege escalation via a buffer overflow during public-key decryption, while CVE-2026-2006 enables attackers to corrupt memory through inadequate checks in symmetric decryption. PostgreSQL has released patches for these vulnerabilities across versions 14.21 to 18.2, and MariaDB addressed a related issue in versions 11.4.10 and 11.8.6. Database administrators are advised to apply updates and audit logs for suspicious activity.
Marlow became a notable figure in Minecraft's Crystal PvP scene, known for her montage videos and distinctive blue and white-haired skin, attracting a large following. However, concerns arose about the authenticity of her content, leading to a scandal involving allegations of deception regarding her identity, with claims that she might be a man using the alias "Danger Mario." Accusations included cheating in ranked matches, staging PvP recreations, and using AI-generated voice tools to maintain her female persona. A report by Dexerto in May 2026 brought the controversy to wider attention, resulting in significant upheaval within MC Tiers, including staff resignations and credibility issues. Prominent players began distancing themselves from Marlow, raising questions about trust and integrity in the competitive Minecraft community.
Square Glade Games has rescheduled the release of their game Outbound to May 11th, three days earlier than planned, to avoid competition with Subnautica 2, which launches on May 14th. The demo for Outbound will be taken offline on May 8th.
Minecraft players are being targeted by a deceptive hacking tool called “Slinky,” which is actually an infostealer known as LofyStealer linked to the Brazilian cybercrime group LofyGang. The malware uses a Node.js-based loader and a C++ payload to extract sensitive browser data, disguising itself as a Minecraft hack. It primarily targets younger players who may unknowingly execute it. The malware operates through a two-stage architecture, with a 53.5 MB loader binary that injects a smaller 1.4 MB payload into browser processes, bypassing detection methods. It collects sensitive information such as cookies, passwords, and credit card details, compressing and encoding the data for exfiltration. The command-and-control (C2) infrastructure is hosted in Brazil, and the malware's design reflects advanced compilation techniques. The campaign is attributed to LofyGang, which has evolved into a more professional entity, posing severe risks to players who download cheats and cracked tools. Indicators of compromise include a specific C2 IP address and associated endpoints.
A group of hackers has declared Denuvo, a digital rights management (DRM) software, as "fully useless" after successfully bypassing its protections, which have been in place since 2014. They achieved this through two main strategies: direct cracking, which removes Denuvo from games, and hypervisor bypass, which deceives Denuvo into functioning normally. These methods have been applied to games like Crimson Desert and Resident Evil Requiem. Recently, a prominent hacker announced the release of hypervisor bypasses for EA Sports games, confirming that all games using Denuvo can now be played for free.
Microsoft has identified an issue affecting the display of security warnings when users open Remote Desktop (.rdp) files across all supported versions of Windows, including Windows 11, Windows 10, and Windows Server. The security warning may not render correctly, making the text difficult to read and buttons misaligned, especially when multiple monitors with different display scaling settings are used. This issue often results in overlapping text or obscured buttons in the warning window. The problem is part of Microsoft's security enhancements introduced with the April 2026 cumulative updates, which aim to mitigate risks associated with malicious RDP connection files. Users receive a one-time educational prompt upon opening an RDP file for the first time, followed by a security dialog that provides information about the file's publisher and resource redirections. RDP files are commonly used in enterprise environments, but their exploitation in phishing campaigns has raised security concerns, particularly by groups like the Russian state-sponsored APT29.
Signal is experiencing a crisis of trust due to security breaches, including successful infiltrations by Russian hackers in Germany and the Netherlands. Senior EU officials have disbanded a Signal group due to hacking fears. Accessing Signal chat content on the dark web can cost between ,000 to ,000, while WhatsApp data is cheaper, ranging from ,000 to ,000. Personal information, such as travel histories, can be bought for 0 to 0, especially for individuals who have traveled to countries known for data leaks. Investigations revealed that Russian diplomats' medical records, banking information, and dating site usernames are available on the black market. Location tracking can be precise when certain applications are downloaded. A Kazakh refugee in Brussels faced high-definition surveillance, and local laws challenge private detectives' effectiveness. State actors have used Israeli spyware like Pegasus to target journalists and adversaries. The prospect of secure communication is diminishing, with online exchanges increasingly seen as vulnerable.
