Hi, Often we find while analyzing malwares or binaries, some malicious domains become inactive after some period of time.
They may be active during initial period of activity, malwares when executed connecting to these domains, these domains then sending malicious files....binaries etc.....but just as soon as this information is being known or the behavior has been captured by IDS/IPS signatures blocking this domain, soon the domain itself become inactive. What do you feel should be the responsibility of IDS/IPS solution providers? I feel keeping track of such domains (live or down) in an automated manner may be one possibility, keeping a signature for some time as a measure of protection another. Also maintaining blacklists of these domains may be helpful. How should one handle such cases? Any ideas? Thanks & Regards, Mayank "DISCLAIMER: This message is proprietary to iPolicy Networks-Security Products division of Tech Mahindra Limited and is intended solely for the use of the individuals to whom it is addressed.
