The cryptojacking operation known as TeamTNT has likely resurfaced as part of a new campaign targeting Virtual Private Server (VPS) infrastructures based on the CentOS operating system. “The initial access was accomplished via a Secure Shell (SSH) brute force attack on the victim’s assets, during which the threat actor uploaded a malicious script,” Group-IB researchers…
Critical security vulnerabilities have been disclosed in six different Automatic Tank Gauge (ATG) systems from five manufacturers that could expose them to remote attacks. “These vulnerabilities pose significant real-world risks, as they could be exploited by malicious actors to cause widespread damage, including physical damage, environmental hazards, and economic losses,” Bitsight researcher
Threat actors are likely employing a tool designated for red teaming exercises to serve malware, according to new findings from Cisco Talos. The program in question is a payload generation framework called MacroPack, which is used to generate Office documents, Visual Basic scripts, Windows shortcuts, and other formats for penetration testing and social engineering assessments….
The Council of the European Union has sanctioned three individuals for allegedly carrying out “malicious cyber activities” against Estonia. The three Russian nationals – Nikolay Alexandrovich Korchagin, Vitaly Shevchenko, and Yuriy Fedorovich Denisov – are officers of the General Staff of the Armed Forces of the Russian Federation (GRU) Unit 29155, it said.

Cybersecurity researchers have flagged a “critical” security vulnerability in Microsoft’s multi-factor authentication (MFA) implementation that allows an attacker to trivially sidestep the protection and gain unauthorized access to a victim’s account. “The bypass was simple: it took around an hour to execute, required no user interaction and did not generate any notification or provide the
Threat hunters have detailed an ongoing campaign that leverages a malware loader called MintsLoader to distribute secondary payloads such as the StealC information stealer and a legitimate open-source network computing platform called BOINC. “MintsLoader is a PowerShell based malware loader that has been seen delivered via spam emails with a link to Kongtuke/ClickFix pages or…
This morning, I came across some interesting news about Google’s updated site reputation abuse policies. Apparently, they’ve revised their main guidelines with some fresh updates.
Introduction As the cybersecurity landscape evolves, service providers play an increasingly vital role in safeguarding sensitive data and maintaining compliance with industry regulations. The National Institute of Standards and Technology (NIST) offers a comprehensive set of frameworks that provide a clear path to achieving robust cybersecurity practices. For service providers, adhering to NIST
Cybersecurity researchers have detailed the activities of an initial access broker (IAB) dubbed ToyMaker that has been observed handing over access to double extortion ransomware gangs like CACTUS. The IAB has been assessed with medium confidence to be a financially motivated threat actor, scanning for vulnerable systems and deploying a custom malware called LAGTOY (aka…
Cybersecurity researchers have warned of a new large-scale campaign that exploits security flaws in AVTECH IP cameras and Huawei HG532 routers to rope the devices into a Mirai botnet variant dubbed Murdoc_Botnet. The ongoing activity “demonstrates enhanced capabilities, exploiting vulnerabilities to compromise devices and establish expansive botnet networks,” Qualys security researcher Shilpesh
