Researchers Uncover Pre-Stuxnet ‘fast16’ Malware Targeting Engineering Software

Researchers Uncover Pre-Stuxnet ‘fast16’ Malware Targeting Engineering Software

Apr 25, 2026 Cyberwarfare / National Security
Cybersecurity researchers have discovered a new Lua-based malware created years before the notorious Stuxnet worm that aimed to sabotage Iran's nuclear program by destroying uranium enrichment centrifuges. According to a new report published by SentinelOne, the previously undocumented cyber sabotage framework dates back to 2005, primarily targeting high-precision calculation software to tamper with results. It has been codenamed fast16 . "By combining this payload with self-propagation mechanisms, the attackers aim to produce equivalent inaccurate calculations across an entire facility," researchers Vitaly Kamluk and Juan Andrés Guerrero-Saade said in an exhaustive report published this week. Fast16 is assessed to predate Stuxnet , the first known digital weapon engineered for disruptive actions , and which served as the basis for the Duqu information stealer rootkit, by at least five years. Stuxnet is widely believed to have been developed by the U.S. and Israel....
FIRESTARTER Backdoor Hit Federal Cisco Firepower Device, Survives Security Patches

FIRESTARTER Backdoor Hit Federal Cisco Firepower Device, Survives Security Patches

Apr 24, 2026 Vulnerability / Network Security
The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has revealed that an unnamed federal civilian agency's Cisco Firepower device running Adaptive Security Appliance (ASA) software was compromised in September 2025 with a new malware called FIRESTARTER . FIRESTARTER, per CISA and the U.K.'s National Cyber Security Centre (NCSC), is assessed to be a backdoor designed for remote access and control. It's believed to be deployed as part of a "widespread" campaign orchestrated by an advanced persistent threat (APT) actor to obtain access to Cisco Adaptive Security Appliance (ASA) firmware by exploiting now-patched security flaws such as - CVE-2025-20333 (CVSS score: 9.9) - An improper validation of user-supplied input vulnerability that could allow an authenticated, remote attacker with valid VPN user credentials to execute arbitrary code as root on an affected device by sending crafted HTTP requests. CVE-2025-20362 (CVSS score: 6.5) - An improper...
LMDeploy CVE-2026-33626 Flaw Exploited Within 13 Hours of Disclosure

LMDeploy CVE-2026-33626 Flaw Exploited Within 13 Hours of Disclosure

Apr 24, 2026 Vulnerability / Network Security
A high-severity security flaw in LMDeploy , an open-source toolkit for compressing, deploying, and serving LLMs, has come under active exploitation in the wild less than 13 hours after its public disclosure. The vulnerability, tracked as CVE-2026-33626 (CVSS score: 7.5), relates to a Server-Side Request Forgery (SSRF) vulnerability that could be exploited to access sensitive data. "A server-side request forgery (SSRF) vulnerability exists in LMDeploy's vision-language module," according to an advisory published by the project maintainers last week. "The load_image() function in lmdeploy/vl/utils.py fetches arbitrary URLs without validating internal/private IP addresses, allowing attackers to access cloud metadata services, internal networks, and sensitive resources." The shortcoming affects all versions of the toolkit (0.12.0 and prior) with vision language support. Orca Security researcher Igor Stepansky has been credited with discovering and reporting th...

ThreatsDay Bulletin: $290M DeFi Hack, macOS LotL Abuse, ProxySmart SIM Farms +25 New Stories

Apr 23, 2026 Hacking News / Cybersecurity News
You scroll past one incident and see another that feels familiar, like it should have been fixed years ago, but it still works with small changes. Same bugs. Same mistakes. The supply chain is messy. Packages you did not check are stealing data, adding backdoors, and spreading. Attacking the systems behind apps is easier than breaking the apps themselves. The exploits are simple but still work, giving attackers easy access. AI tools are also part of the problem now. They trust bad input and take real actions, which makes the damage bigger. Then there are quieter issues. Apps take data they should not. Devices behave in strange ways. Attackers keep testing what they can get away with. No noise. Just ongoing damage. Here is the list for this week’s ThreatsDay Bulletin. State-backed crypto heist North Korea Likely Behind KelpDAP $290M Crypto Heist Inter-blockchain communication protocol LayerZero has revealed that North Korean thr...
