SolarWinds Cyber Intel Analysis Part 2: A Look at Additional CISA-Published IoCs

A few weeks back, we added unpublicized artifacts to the list of indicators of compromise (IoCs) published by both FireEye and Open Source Context back in December 2020. Some would have thought that would put a stop to the havoc the SolarWinds threat actors have been wreaking, but the group targeted Malwarebytes just recently according to a company report. more

How to Monitor IP Netblocks for Possible Targeted Attacks

A couple of weeks back, a security researcher alerted his LinkedIn contacts about possibly ongoing targeted attacks stemming from the Iranian subnet 194[.]147[.]140[.]x.

Enriching Intrusion Detection and Prevention Systems with IP and Domain Intelligence

Intrusion detection systems (IDSs) and intrusion prevention systems (IPSs), collectively called "intrusion detection and prevention systems (IDPSs)," monitor network traffic to stave off unauthorized access. Roughly speaking, an IDS detects possible malicious network activities, while an IPS stops malicious traffic from entering and possibly damaging a network. more
