007 First Light рискует оказаться на торрентах до официального релиза

The game 007 First Light is set to launch on May 27, but there are concerns about it being leaked onto torrent sites before its release. Players who pre-order the game can start playing 24 hours earlier than the general public, increasing the risk of piracy. Recent trends show an increase in fully functional pirated versions of major games appearing before their official launches, including titles like Pragmata and Death Stranding 2. There is no confirmed information about the use of the anti-piracy system Denuvo on Steam, and even with such protections, hackers have been able to bypass them. Factors contributing to early availability of game builds to hackers include failures in pre-loading systems and actions by reviewers. Even if a game avoids leaks initially, it is likely to be pirated eventually.

MSHTA abuse helps malware hide in Windows processes

Bitdefender's research highlights the use of Microsoft's MSHTA utility in malware attacks, noting its default activation in Windows systems. Cybercriminals exploit MSHTA to execute malicious scripts under the guise of legitimate processes, linking it to various malware families like LummaStealer and PurpleFox. The study reports a rise in MSHTA-related detections, indicating a shift towards "living-off-the-land" tactics that utilize legitimate tools to evade security alerts. Social engineering is identified as a common entry point for attacks, employing deceptive methods such as fake software downloads and phishing links. MSHTA can retrieve and execute additional payloads through multi-stage chains, complicating detection efforts. The attacks target sensitive information, including credentials and financial data, and the continued presence of MSHTA poses risks as it allows threat actors to conceal malicious actions. To mitigate these threats, organizations are advised to restrict or disable legacy scripting tools and exercise caution with untrusted downloads. The report emphasizes the challenge of detecting unusual behaviors associated with legitimate utilities in the context of cyber threats.

Trapdoor Android Ad Fraud Scheme Hit 659 Million Daily Bid Requests Using 455 Apps

Cybersecurity researchers have identified an ad fraud and malvertising operation called Trapdoor, targeting Android users with 455 malicious applications and 183 command-and-control domains. Users often download these disguised apps, which initiate malvertising campaigns and lead to further downloads of malicious applications. At its peak, Trapdoor generated 659 million bid requests daily, with over 24 million downloads of the associated apps, primarily from the United States. The operation exploits install attribution tools to activate malicious activities only for users acquired through fraudulent ad campaigns, while suppressing such behavior for organic downloads. Trapdoor employs advanced evasion techniques, including obfuscation and impersonation of legitimate software, to avoid detection. Google has removed the identified malicious apps from the Play Store in response to the threat.

20-Year-Old PostgreSQL Flaw Gets Public PoC Exploit for Remote Code Execution

A proof-of-concept exploit for CVE-2026-2005 has been released, highlighting a significant vulnerability in the PostgreSQL pgcrypto extension that allows for remote code execution (RCE). This flaw, rooted in legacy code for nearly 20 years, enables attackers to escalate privileges and execute arbitrary commands on compromised servers. The vulnerability is found in the PGP session key parsing logic of the pgcrypto module and involves a heap-based buffer overflow, granting attackers arbitrary read and write access to memory. The exploit, shared by researcher “var77” on GitHub, demonstrates a multi-stage process that bypasses modern security measures like Address Space Layout Randomization (ASLR) using specially crafted PGP messages. The attack involves several steps, including heap pointer leakage, arbitrary memory read, identification of executable memory regions, and privilege escalation to the PostgreSQL superuser level, ultimately allowing the execution of OS-level commands. The vulnerability affects PostgreSQL deployments with the pgcrypto extension enabled, particularly those using vulnerable code versions. Successful exploitation can lead to full database compromise, unauthorized data access or modification, and potential lateral movement within networks. Organizations are advised to update PostgreSQL, restrict pgcrypto usage, limit user privileges, and monitor for unusual activity to mitigate risks.

Windows CE Ported to Nintendo 64

Throaty Mumbo successfully ran Windows CE 2.11 on the Nintendo 64 by leveraging the shared architecture of both systems, which are based on the MIPS R4000 processor family. The project involved a month of reverse engineering, using Microsoft toolchains, custom hardware modifications, and debugging techniques. An EverDrive flash cartridge was used to load custom ROMs, and a USB connection facilitated uploads from a PC. Challenges included crashes with the initial EverDrive cartridge, which were resolved by upgrading to the EverDrive-64 X7. A custom kernel clone was created to troubleshoot issues with the stock Windows CE kernel, ultimately allowing the project to revert to the unmodified version. The Nintendo 64 controller was repurposed as a mouse, and standard Windows CE applications could be launched from the desktop. Comprehensive build details are available on GitHub.
