"Cyberattacks that meet upper severity thresholds set by the UK government's cyber agents have risen 50 percent in the last year, despite almost zero change in the volume of cases handled. GCHQ's cyber arm, the National Cyber Security Centre's (NCSC), said in its annual review published today that its incident management team handled 429 cyberattacks on organizations in the past 12 months, one fewer than the same reporting period in last year's review."
"Category 4 - Substantial incident: Attacks that have a serious impact on a medium-sized organization, or those that pose a considerable risk to a large one. NCSC or law enforcement leads the response. Category 5 - Moderate incident: An attack on a small organization that could impact a larger one. Law enforcement leads the response. Category 6 - Localized incident: An attack on an individual, or one that could shape into an attack on an SMB. Local police lead the response."
The National Cyber Security Centre's incident management team handled 429 cyberattacks in the past 12 months, one fewer than the previous reporting period. Nationally significant attacks increased to 204, a 48 percent rise year-on-year, and highly significant attacks rose to 18, a 50 percent increase, marking a third consecutive annual rise in severity. The NCSC classifies incidents into six categories from Category 1 national cyber emergency to Category 6 localized incidents, with different leadership and response responsibilities allocated to NCSC, law enforcement, cross-government teams, senior ministers and local police. The data shows increasing impact despite stable overall incident counts.
