Background for this topic.
Investigation is the systematic examination of an event, claim, or suspected activity to establish what happened, when it happened, and who or what was involved. In information security, it commonly covers suspected intrusions, misuse of accounts, data exposure, fraud, and control failures. Investigators reconstruct an event from sources such as authentication records, endpoint artifacts, network telemetry, cloud logs, and disk or memory images, then determine the affected systems, data, and attack path.
Reliable investigations depend on preserving evidence without altering it, recording its provenance, and separating confirmed facts from assumptions. Findings can guide containment and recovery, reveal vulnerabilities that require remediation, and provide threat intelligence about tools or techniques used against an organization. Privacy and legal requirements may restrict what data can be collected or shared, while weak logging, short retention, or uncontrolled access can leave important questions unanswered and undermine any disciplinary, regulatory, or judicial action.

More than 20 Brazilian government websites were hijacked and turned into malware delivery channels in an active PhantomEnigma campaign uncovered by ANY.RUN, a leading provider of interactive malware analysis and threat intelligence solutions
Building a shortlist for an AI SOC evaluation can be tough. SIEM, SOAR, and pureplay AI SOC vendors are all saying the same thing. But behind the identical label sit very different products, from chat assistants bolted onto a legacy SIEM to agent platforms that run detection, triage, investigation, and response on their own data foundation
The Security Service of Ukraine (SSU) said it, together with the U.S. Federal Bureau of Investigation (FBI), uncovered a long-running campaign orchestrated by Russian intelligence services to break into the messaging accounts of government officials, military personnel, politicians, and activists in Ukraine, Europe, and the U.S
Despite the abundance of telemetry at analysts’ disposal, many security operations teams struggle to answer a few basic questions during incident investigation: What happened? What evidence do we have? How do we know we’re seeing it all, in context? Answering these questions requires teams to go beyond alerts, the most common basis for initial triage. But investigations (and their outcomes)

What is really slowing Tier 1 down: the threat itself or the process around it? In many SOCs, the biggest delays do not come from the threat alone. They come from fragmented workflows, manual triage steps, and limited visibility early in the investigation. Fixing those process gaps can help Tier 1 move faster, reduce unnecessary escalations, and improve how the entire SOC responds under pressure
Threat actors with ties to Iran successfully broke into the personal email account of Kash Patel, the director of the U.S. Federal Bureau of Investigation (FBI), and leaked a cache of photos and other documents to the internet
Threat actors affiliated with Russian Intelligence Services are conducting phishing campaigns to compromise commercial messaging applications (CMAs) like WhatsApp and Signal to seize control of accounts belonging to individuals with high intelligence value, the U.S. Cybersecurity and Infrastructure Security Agency (CISA) and Federal Bureau of Investigation (FBI) said Friday
The most dangerous phishing campaigns aren’t just designed to fool employees. Many are designed to exhaust the analysts investigating them. When a phishing investigation takes 12 hours instead of five minutes, the outcome can shift from a contained incident to a breach
