What is ACRStealer?

ACRStealer is an **info stealer malware** designed to **extract sensitive information** from infected systems, including:

– **Antivirus identification** – determining which security solutions are present to evade detection.
– **Crypto wallet theft** – targeting stored cryptocurrency assets.
– **Login credentials theft** – stealing usernames and passwords for financial services, corporate accounts, and personal data.
– **Browser information extraction** – harvesting stored passwords, cookies, and browsing history.
– **File Transfer Protocol (FTP) credential theft** – compromising access to cloud and remote servers.
– **Text file harvesting** – reading and extracting information from text documents.

While information stealers are not new, **ACRStealer stands out** due to its **stealth tactics, sophisticated distribution, and abuse of legitimate cloud platforms**.

SSRF-Vulnerabilities-KrishnaG-CEO

OWASP Top 10 API Security Risks – 2023: API7:2023 – Server-Side Request Forgery (SSRF)

by

SSRF vulnerabilities occur when an API fetches a remote resource using a user-supplied Uniform Resource Identifier (URI) without adequate validation. This oversight allows attackers to manipulate the request, coercing the server to interact with unintended destinations. These attacks bypass traditional network controls like firewalls and VPNs, making them particularly insidious.

M2: Insecure Data Storage – A Penetration Tester’s Guide

by

Insecure data storage refers to the practice of storing data in a manner that makes it vulnerable to unauthorised access, tampering, or theft. This can occur in various forms, such as improperly encrypted files, exposed databases, or unprotected cloud storage solutions. The consequences of insecure data storage can be far-reaching, ranging from financial losses to reputational damage and legal ramifications.

Penetration testers need to thoroughly evaluate an organisation’s data storage mechanisms to identify weaknesses and implement corrective measures before malicious actors can exploit them. This is particularly important as organisations increasingly store data in cloud environments, mobile applications, and third-party servers, each introducing unique security challenges.

PHP Web Shells: A Comprehensive Analysis for Penetration Testers

by

A PHP web shell is a script, written in PHP, that allows attackers to execute commands on a compromised web server remotely. These scripts act as a backdoor, providing attackers with access to sensitive data, server resources, and the capability to escalate their attack.

Multi-Stage Cyber Attacks: Understanding Their Sophistication and Building Robust Defences

by

Cyber attacks have evolved into intricate operations, often executed in multiple stages to achieve maximum impact while evading detection. Multi-stage cyber attacks leverage complex execution chains to mislead victims, bypass traditional defences, and deliver devastating outcomes. For organisations and individuals alike, understanding the mechanics of these attacks is essential for crafting effective defence strategies.

Multi-stage cyber attacks are a formidable challenge, but with offensive security techniques, organisations can move from reactive to proactive defence. By adopting vulnerability assessments, penetration testing, cyber forensics, malware analysis, and reverse engineering, businesses can detect and neutralise threats before they escalate.
