This ‘classic’ decades-old SQL injection flaw could let hackers take over entire Windows servers, thanks to a nifty database trick

Security researchers from Huntress discovered a sophisticated SQL Injection (SQLi) attack that led to the deployment of a rare toolkit called Khunt. The attackers exploited a public-facing application backed by an Oracle database by failing to validate user input, allowing malicious SQL commands to be executed. The Khunt toolkit enabled activities such as executing operating system commands, stealing credentials, and exfiltrating registry hive data. Experts recommend robust defense mechanisms, including input sanitation, regular security audits, and the implementation of web application firewalls to protect against such attacks.

Hackers are hiding malware behind AI agents that antivirus cannot see

Sergey Lozhkin, head of Kaspersky’s global research and analysis team for the Asia-Pacific, Middle East, Turkey, and Africa, reported an increase in malware injection attacks targeting AI agents, particularly from outside an organization’s network. He noted that traditional signature-based analysis is becoming ineffective as AI skills operate in the cloud, connecting to external resources. Dmitry Galov, leading Kaspersky’s research for Russia and the CIS, emphasized the importance of behavioral analysis and sandboxing AI applications to combat these threats. Lozhkin warned that the rapid growth of skills and plugins requires organizations to adopt innovative security measures, as old models are no longer sufficient.

ThreatsDay: Android Spyware, PLC Attacks, AI Image Prompt Injection + 12 More Stories

GitHub will reject command-line support bundle uploads from outdated versions of GitHub Enterprise Server lacking security patches starting August 18, 2026. The npm package @copilot-mcp/apex has been identified as a post-install dropper that installs a macOS infostealer, phishing for sensitive information and maintaining a connection to an attacker's server. A rogue extension on the Microsoft Visual Studio Code marketplace, "Markdown All Pro," impersonates a legitimate tool and opens a backdoor after installation. A phishing campaign targeting Portuguese users delivers the Lampion banking malware, which has been active since 2019. DoubleVerify reports a rise in "AfterCall" apps that exploit user permissions for ad fraud. The GhostCommit attack method hides malicious instructions within PNG images in pull requests. The U.S. government has updated its advisory on Iranian-affiliated cyber activity targeting operational technology devices. An Android app posing as a civil defense alert system has been found to contain malware for data harvesting. An Iranian threat actor is distributing MarkiRAT malware through fake applications. An analysis of 28 AI-coded applications revealed 434 vulnerabilities, prompting Cisco to introduce Antares to identify vulnerabilities in codebases. A Russian-speaking threat actor is dismantling guardrails on AI models to create offensive tools.

Hundreds of GitHub repos found posing as real software to push malware

Cybersecurity firm ArcticWolf has identified 292 malicious GitHub repositories that impersonate legitimate software tools, part of a campaign to deliver a new variant of the BoryptGrab infostealer. This malware can extract sensitive information from 19 web browsers, 32 cryptocurrency wallets, messaging applications like Telegram and Discord, gaming platforms such as Steam, and Windows Credential Manager. It can also exfiltrate files from users' Desktop and Documents folders and capture screenshots. This variant bypasses Chrome’s App-Bound Encryption using direct code injection and does not include an anti-analysis layer or conceal itself, aiming to harvest data quickly without persistence. The malicious activity began in late June, with most repositories removed from GitHub, though several dozen remain active. GitHub's status as a key platform in the open-source community makes it a target for cybercriminals, emphasizing the need for developers to thoroughly vet code before integration.

Hackers Use Fake VLC Executable and Malicious libvlc.dll to Deploy ValleyRAT

Cybercriminals are exploiting the VLC media player to install ValleyRAT, a remote access trojan, by embedding malware in a seemingly harmless file linked in phishing emails. The attack starts with an email that prompts the victim to download a ZIP archive containing a fake VLC executable and a malicious DLL named libvlc.dll. This method uses DLL sideloading to execute the malware under the guise of a legitimate application. Once executed, the malware establishes persistence by creating a registry entry and connects to a remote server to retrieve the final payload. ValleyRAT employs evasion tactics to avoid detection, including assessing system characteristics before executing harmful actions and using a fileless approach to deliver the payload directly into memory. Researchers have identified indicators of compromise, including specific SHA1 hashes and URLs associated with the malicious campaign.

Critical PHP PDO Driver Bugs Expose Firebird SQL Injection and PostgreSQL DoS Risks

A recent examination of PHP's database driver layer revealed two significant vulnerabilities in PHP Data Objects (PDO) affecting the pdo_firebird and pdo_pgsql drivers. The first vulnerability, CVE-2026-25289, allows SQL injection attacks through NUL byte manipulation in quoted strings, compromising the safety of SQL statements. The second vulnerability, CVE-2026-25290, can cause application crashes due to null pointer dereferencing when invalid multibyte character sequences are processed. Both vulnerabilities stem from assumptions about C string handling and have been addressed in a security release. Researchers recommend treating binary input as untrustworthy and encapsulating financial workflows within atomic transactions.

PDO PostgreSQL Bug Triggers NULL Pointer Dereference and Crashes PHP Worker Processes

Researchers at Positive Technologies have identified two significant vulnerabilities in the PHP Data Objects (PDO) extension layer, both posing high severity risks. The first vulnerability (CVE-2025-14180) leads to a NULL pointer dereference, causing PHP worker processes to crash. It affects PHP versions 8.1.x prior to 8.1.34, 8.2.x before 8.2.30, 8.3.x before 8.3.29, 8.4.x before 8.4.16, and 8.5.x before 8.5.1. This issue occurs when the pdo_pgsql driver operates with PDO::ATTR_EMULATE_PREPARES enabled, allowing a remote attacker to exploit it without authentication by submitting malformed character sequences. The second vulnerability (CVE-2025-14179) allows for SQL injection and affects PHP versions 8.2.x before 8.2.31, 8.3.x before 8.3.31, 8.4.x before 8.4.21, and 8.5.x before 8.5.6. It arises from a mishandling of NUL bytes in the Firebird driver during the PDO::prepare() process, despite the quoting routine functioning correctly. Additionally, the audit revealed an integer overflow in PostgreSQL’s libpq client library and an information disclosure flaw in Firebird 3’s fbclient.

Hackers Use Fake VLC Executable and Malicious libvlc.dll to Deploy ValleyRAT

Cybercriminals are using a sophisticated method to bypass security measures by embedding malware within the VLC media player. This campaign exploits VLC to install ValleyRAT, a remote access trojan, through phishing emails that contain links to download a seemingly harmless file. Once the file is opened, it activates a hidden backdoor that evades detection by antivirus solutions. The malware has been active since 2023, with a significant increase in activity noted through 2025 and into 2026, particularly targeting Chinese and Japanese-speaking users. The infection process begins when a victim clicks a link in a phishing email, leading to a ZIP archive containing a disguised executable and a malicious DLL (libvlc.dll). The executable mimics a legitimate VLC file, and when executed, it loads the DLL, allowing the malware to run under the guise of VLC. The malware establishes persistence by creating a registry entry and connects to a remote server to retrieve the final payload. ValleyRAT employs evasion tactics to avoid detection, such as performing checks on system behavior and using a fileless approach to inject its payload directly into memory, avoiding storage on disk. Researchers recommend training employees to recognize suspicious filenames and deploying endpoint detection tools to identify DLL sideloading behavior. For organizations affected by this campaign, isolating compromised systems and reviewing security logs are critical initial steps. Indicators of compromise include a malicious email domain, a ZIP archive containing a fake VLC executable, and a download URL for ValleyRAT.
