Post-quantum migration gets harder when every user holds a key
Help Net Security
Christopher Smith, CEO of Quantus, discusses the challenges of migrating to post-quantum cryptography, particularly in sectors like banking and healthcare. He reveals that many institutions still hold outdated cryptographic inventories, including default passwords and admin keys from former employees, which complicates the upgrade process. Smith explains that the larger key sizes required for post-quantum systems break previous assumptions about encryption protocols like IPsec, SSH, and TLS. This places a significant burden on organizations looking to upgrade their security measures, as user-held keys in blockchains create additional hurdles. The conversation raises awareness of the potential risks associated with a 'silent quantum break,' where vulnerabilities could be exploited without immediate detection. This situation emphasizes the urgent need for funding and resources to address these cryptographic challenges.
Actively Exploited
Cisco has issued a patch for a serious vulnerability identified as CVE-2026-20349, which affects its Secure Firewall ASA and FTD devices. This flaw can be exploited remotely without the need for authentication, allowing attackers to launch Denial of Service (DoS) attacks against the devices. The ability to target these firewalls without prior access poses a significant risk to organizations that rely on Cisco's security solutions. Users of affected devices are urged to apply the updates provided by Cisco promptly to mitigate potential exploitation. The urgency of this patch reflects the growing trend of vulnerabilities being targeted in the wild, emphasizing the need for vigilant cybersecurity practices.
A recent study by Picus Labs, detailed in their Blue Report 2026, reveals a mixed picture of enterprise cybersecurity defenses. The report, which analyzed over 338 million attack simulations, indicates that while organizations are becoming more adept at thwarting loud and apparent attacks, their defenses against quieter, more subtle threats have seen little improvement. This suggests that while companies may be better prepared for obvious threats, they remain vulnerable to stealthy attacks that can go unnoticed. As attackers evolve their tactics, enterprises need to focus on enhancing their defenses against these less visible threats to ensure comprehensive protection.
AI deployments are stretching enterprise security to its limits
Help Net Security
A recent survey by NetFoundry reveals that Chief Information Security Officers (CISOs) and Chief Technology Officers (CTOs) anticipate a 14% increase in their organizations' attack surface due to AI deployments over the next year. Most organizations lack visibility into these AI tools, which raises concerns about employees using unapproved applications without oversight. About 90% of the surveyed executives expressed worry over this issue, indicating a significant gap in security management. As businesses increasingly adopt AI technologies, the pressure to secure these systems is mounting, posing risks not just to individual organizations but also to broader cybersecurity frameworks. This situation calls for immediate attention to ensure that AI use does not lead to vulnerabilities that could be exploited by attackers.
Actively Exploited
The Kimwolf botnet has been revamped following police actions that previously dismantled it, including server seizures and the arrest of an alleged operator. Researchers indicate that the botnet now employs tactics to disguise its attacks as normal Chrome web traffic, complicating detection efforts. Additionally, it retrieves commands from the Ethereum blockchain, enhancing its resilience against future takedowns. This evolution poses a significant challenge for cybersecurity experts as it becomes harder to trace and mitigate. The resurgence of Kimwolf highlights ongoing vulnerabilities in network security and the persistent threat posed by sophisticated botnets.
