Learn about common defense evasion techniques used in malicious shell scripts and how Uptycs detects them. . Attackers use malicious shell scripts as an initial vector to download malicious payloads to the victim system. In the earlier days, base64 and other common encoding schemes were used to evade defensive parameters. But nowadays, threat actors are adopting newer techniques that include commands to disable firewalls, monitoring agents etc. The link for this article located at Uptycs Blog is no longer available. . Threat actors leverage command-line scripts to undermine security measures, gaining insights into novel evasion strategies and Uptycs monitoring capabilities..

Security researchers at the Black Hat show in Las Vegas are debating whether rootkits that mimic virtual machines can ever be detected. I have heard about virtual machine rootkits before but I did not think that they were undetectable. What do you think, are these rootkit really invisible? . She returned to Black Hat this year to acknowledge that researcher Edgar Barbosa has come closest to devising a method for detecting Blue Pill. "Congratulations to Edgar," she said, during the highly technical presentation she made with her colleague, researcher Alexander Tereshkin. Rutkowska said they hadn't yet found a way to evade Barbosa's so-called counter-based detection method, which he presented during July's SyScan conference.

Last year I wrote a two-part paper about SQL Injection and Oracle. That paper explored which SQL injection techniques are possible with Oracle, gave some simple examples on how SQL injection works and some suggestions on how to prevent attackers and malicious employees using these methods. This paper takes the subject further and investigates the possibilities for the Oracle Database Administrator (DBA) to detect SQL injection in the wild against her Oracle database. Is it possible to detect SQL injection happening? If so what tools and techniques can be employed to achieve this? The main focus of this paper is to explore some simple techniques in extracting logging and trace data that could be employed for monitoring. The aim is to show the reader what data is readily available so they can make their own mind up about what can be useful. The paper will not cover commercial solutions. Because a true SQL injection tool would involve writing a parser or filter to analyse the SQL statements a fully featured tool is unfortunately beyond the scope of a short paper - I leave the implementation of such a tool to interested readers.

Key approaches include enabling logging, monitoring logs, and analyzing user activity.. SQL Injection Detection, Oracle Security, Monitoring Techniques. . LinuxSecurity.com Team
