Today's malware will use some clever technologies to circumvent the traditional signature-based anti-malware detection. Intrusion prevention systems, web page filtering, and Anti-Virus products are no longer able to defend against new categories of attackers. Such new categories combine complex malware with persistent remote access features, the objective is to s

Iv. synonyms(a) What are synonymsA synonym is essentially an alias for a specified schema object. Synonyms provide a degree of security by masking the names and owners of objects and providing location transparency for remote objects in a distributed database. At the same time, the use of synonyms is better, which reduces the complexity of SQL statements of database users. Synonyms allow a base object to be renamed or moved, at which point a

First, the Reverse debugging technology
Anti-debugging technology is a common kind of counter detection technique, because malware always attempts to monitor its own code to detect if it is being debugged. To do this, the malware can check whether its own code is set to break the point, or directly through the system to detect the debugger.
1. Breakpoint
In order to detect if its code is set to a breakpoint
CREATE VIEW statement, Oracle creates the view even if there is a series of cases.The query for a view definition references a table that does not exist.The query for the view definition references columns that are not valid in an existing table.The owner of the view does not have the required permissions.In these cases, Oracle only checks for syntax errors in the CREATE VIEW statement. If the syntax is correct, the view is created and the definition of the view exists in the data dictionary. H
