The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Friday added two security flaws impacting Microsoft SharePoint and Mikrotik RouterOS to its Known Exploited Vulnerabilities ( KEV ) catalog, citing evidence of active exploitation. The vulnerabilities in question are as follows - CVE-2026-65660 (CVSS score: 8.8) - A code injection vulnerability in Microsoft Office SharePoint that allows an authorized attacker to execute code over a network. CVE-2026-67279 (CVSS score: 6.9) - An improper enforcement of behavioral workflow vulnerability in  Mikrotik RouterOS that could allow an unauthenticated client to open a session channel and send an exec request. As reported by The Hacker News earlier this week, CVE-2026-65660 was originally described by Microsoft as a spoofing vulnerability impacting SharePoint Server. The tech giant has since updated the advisory to state that it could be abused to obtain remote code execution. "As of 9/25/2026, Microsoft ...

Kiteworks (formerly Accellion) is urging customers to shut down their systems as a precautionary measure for nine hours over the weekend after it received threat intelligence about an imminent cyber attack. "Kiteworks received credible threat intelligence from federal intelligence authorities indicating that a threat actor may attempt to target some Kiteworks systems," said Frank Balonis, Chief Information Security Officer (CISO) at Kiteworks. "Out of an abundance of caution, we notified customers directly and recommended a precautionary shutdown window while we continue to work through the matter with federal intelligence authorities." The company said it has not found any evidence that its customers' systems have been compromised, emphasizing the advisory is preventative rather than a response to a confirmed hack. The development was first reported by German news publication Heise. Kiteworks did not disclose which law enforcement agency alerted the ...

Two actions-cool GitHub Actions have been disabled for a second time after the repositories became accessible last week, months after they were compromised during the May 2026 Mini Shai-Hulud campaign . The affected GitHub Actions are listed below - actions-cool/issues-helper actions-cool/maintain-one-comment Visiting either of the repositories now shows the message: "Access to this repository has been disabled by GitHub Staff due to a violation of GitHub's terms of service. If you are the owner of the repository, you may reach out to GitHub Support for more information." "On September 16, 2026, both repositories became accessible again," Socket researcher Karlo Zanki said . "Their release tags were not cleaned up first. They still point to the malicious content introduced on May 18, so any workflow that references either action by a version tag resumed downloading and executing the payload on its next run." The two GitHub Actions work...

Cybersecurity researchers have flagged a new version of PamStealer that ensures that the main payload can only be recovered using a server-side decryption chain. The latest artifacts, per Jamf Threat Labs, continue to rely on the same JavaScript for Automation (JXA) dropper mechanism, but modify the lure and the delivery method. "Where earlier variants embedded their payload key material directly in the JXA source, it now fetches a purpose-built decryption utility and completes a key exchange with the server before the payload can be unwrapped," security researcher Thijs Xhaflaire said in an analysis. "Without the server's cooperation, the payload cannot be recovered statically." A second major change is the choice of the decoy itself. While previous versions observed in July and August 2026 were observed using fake websites masquerading as Maccy, Scoppr, and Nancy Clipboard, victims are now lured through a bogus website ("wavel[.]app") advert...

Security leaders keep debating whether AI will produce an entirely new class of cyberattack. The nearer change is quieter and already visible: AI has made a failed attack cheap to retry. The routine version looks like this. An attacker lands on a low-privilege cloud account, and the first try at privilege escalation goes nowhere. That dead end used to cost hours of documentation reading, permission checks, and script debugging, and plenty of operators simply got stuck. With a model in the loop, the error gets explained, the script gets fixed, and a fresh enumeration path is under test within minutes. No step in that sequence is a new capability. Together they strip time, skill, and cost out of the unglamorous middle of an intrusion, the research and troubleshooting that sit between intent and outcome. What the threat reporting shows The public record traces the arc. In early 2025, Google's Threat Intelligence Group found state-backed actors treating generative AI as a prod...

Cryptocurrency exchange Bitget said suspected North Korean threat actors have stolen $351.6 million from its hot and warm wallets.  "At 18:31 UTC on September 24, 2026, Bitget's security systems identified unauthorized transfers involving a limited number of hot wallets," Bitget said in a post shared on X. "Bitget's cold wallets and the overwhelming majority of platform assets remain secure and unaffected." The company emphasized that customer account balances remain accurate, and deposits and trading continue to operate normally. However, withdrawals have been temporarily suspended out of an abundance of caution while a "comprehensive security review" is underway. Bitget did not disclose any details on how the attack took place, but said it has enlisted the help of Google-owned Mandiant and SlowMist for a third-party investigation. "Bitget Wallet operates as a self-custodial wallet on a completely separate and independent infrastruc...
