Background for this topic.
Outage is a period when a system, network, application, or online service is unavailable or cannot perform its intended function. It may be planned maintenance or an unplanned disruption caused by equipment or software failure, misconfiguration, a dependency problem, natural hazards, or a denial-of-service attack. The tag generally concerns availability incidents, not every performance issue or security breach.
For security practitioners, an outage requires determining whether malicious activity contributed to the disruption while preserving relevant logs, network telemetry, and system state for investigation. Defenses include capacity planning, segmented and redundant architecture, tested failover and recovery procedures, and controls that limit the effect of DDoS traffic or compromised dependencies. Emergency changes made during recovery should be authorized and recorded, since they can create new vulnerabilities or affect data integrity. Clear incident ownership and communications help coordinate technical response without obscuring the cause or scope.
Researchers track the healthcare sector as experiencing the biggest financial losses, with banking and transportation following close behind.
'In the short term, they're going to have to do a lot of groveling' Analysis The great irony of the CrowdStrike fiasco is that a cybersecurity company caused the exact sort of massive global outage it was supposed to prevent. And it all started with an effort to make life more difficult for criminals and their malware, with an update to its endpoint detection and response tool Falcon.…
Concerns abound over why it has taken so long to recover compared to competitors The US Department of Transportation (DoT) is investigating Delta Air Lines over its handling of the global IT outage caused by CrowdStrike's content update.…
CrowdStrike has published a preliminary Post Incident Review into the global IT outage on July 19, revealing the issue came from a Rapid Response Content update
Cybersecurity firm CrowdStrike on Wednesday blamed an issue in its validation system for causing millions of Windows devices to crash as part of a widespread outage late last week
A painful recovery from arguably one of the worst IT outages ever continues, and the focus is shifting to what can be done to prevent something similar from happening again.
How could this happen to us? We were supposed to be two versions behind? If administrators have learned anything from the CrowdStrike chaos, it's to understand exactly what delayed updates mean – or don't mean – in the anti-malware world.…
Latest trend follows various malware campaigns that began just hours after IT calamity Thousands of typosquatting domains are now registered to exploit the desperation of IT admins still struggling to recover from last week's CrowdStrike outage, researchers say.…
More baddies go it alone as trust in big gangs withers, claims Europol A fresh report from Europol suggests that the recent disruption of ransomware-as-a-service (RaaS) groups is fragmenting the threat landscape, making it more difficult to track.…
Historic IT outage expected to spur regulatory scrutiny, soul-searching over "monoculture" of IT infrastructure - and cyberattack threats.
Cybercriminals have launched phishing campaigns purporting to support organizations impacted by the global IT outage, caused by a CrowdStrike Falcon issue
Rapid restore tool being tested as Microsoft estimates 8.5M machines went down Updated CrowdStrike's now-infamous Falcon Sensor software, which last week led to widespread outages of Windows-powered computers, has also been linked to crashes of Linux machines.…
