Background for this topic.
An exploit is code, data, or a sequence of actions that uses a software, hardware, or configuration vulnerability to produce unintended behavior. Depending on the flaw and the attacker’s access, it may enable unauthorized code execution, privilege escalation, information disclosure, or denial of service. Exploitation can occur remotely through exposed services, web applications, or client software, or locally after an attacker gains limited access.
Exploitation matters because a vulnerability becomes an active attack path when the required conditions are reachable and exploitable. Defenders should inventory affected assets, prioritize remediation when exploitation is known or credible, apply patches or vendor mitigations, and reduce exposure through access controls, segmentation, and secure configuration. Monitoring for exploit-specific indicators—such as abnormal requests, unexpected processes, or privilege changes—supports detection; systems suspected of successful exploitation require containment and investigation for follow-on access.
Researchers say tens of thousands of instances remain publicly reachable Security researchers have confirmed that threat actors have exploited the maximum-severity vulnerability affecting Fortra's GoAnywhere managed file transfer (MFT), and chastised the vendor for a lack of transparency.…
An attack campaign has been identified which exploits vulnerabilities in Cisco Adaptive Security Appliance software
The U.K. National Cyber Security Centre (NCSC) has revealed that threat actors have exploited the recently disclosed security flaws impacting Cisco firewalls as part of zero-day attacks to deliver previously undocumented malware families like RayInitiator and LINE VIPER
CISA Issues Emergency Directive After Cisco Exploits Persist After RebootCISA issued an emergency directive Thursday after discovering an advanced hacking campaign exploiting two persistent zero-days in Cisco firewall gear - malware that survives system reboots and upgrades - forcing agencies to disconnect vulnerable devices by Friday.
The hackers are likely trying to collect data to feed the development of zero-day exploits, said Google researchers
Researchers Uncover Covert Chinese Access to US Service Provider InfrastructureMandiant said it has tracked a Chinese-linked espionage campaign using BRICKSTORM malware to quietly embed within U.S. infrastructure and service providers for over a year, exploiting appliance-level blind spots to maintain persistence, evade detection and potentially develop zero-day exploits.
Think payment iframes are secure by design? Think again. Sophisticated attackers have quietly evolved malicious overlay techniques to exploit checkout pages and steal credit card data by bypassing the very security policies designed to stop them
An unnamed federal agency was hacked last year after threat actors exploited a critical GeoServer vulnerability
Cloud security company Wiz has revealed that it uncovered in-the-wild exploitation of a security flaw in a Linux utility called Pandoc as part of attacks designed to infiltrate Amazon Web Services (AWS) Instance Metadata Service (IMDS)
CISA has revealed that attackers breached the network of an unnamed U.S. federal civilian executive branch (FCEB) agency last year after compromising an unpatched GeoServer instance. [...]
