Method and apparatus for mitigating the effects of security threat involving malicious code concealed in computer files (for example computer viruses, etc.). The method operates by inserting additional strings of arbitrary length within computer files of known type which may contain such security threats. The strings are chosen to have no substantial effect on the files in normal operation, but potentially disrupt attack code located in the file. Inserted sequences may incorporate a character sequence which, if interpreted as code, halts execution of that program. Alternatively, or in addition, character sequences may be deleted or reordered provided that they have no effect on normal interpretation of the file. As a result, the effect of malicious code operating successfully as intended by an attacker may be mitigated. The methods do not require prior knowledge of the nature of a specific threat and so provide threat mitigation for previously unidentified threats.
