Attackers are impersonating popular AI products to distribute malware, steal browser sessions, and compromise business accounts. ANY.RUN linked 1,258 public sandbox analyses to fake AI campaigns between April and October of 2026.  The campaigns also increase operational pressure on MSSPs serving US businesses, which accounted for 16% of country-attributed targets.  Similar attacks appearing across different customers can trigger repetitive investigations, consume analyst capacity, and extend response times, making it harder to maintain consistent service levels as threat activity grows. How Fake AI Attacks Are Reaching US Businesses Fake AI attacks pose a serious risk to business security The campaigns investigated by ANY.RUN use familiar AI brands to encourage employees to execute malicious commands, install compromised applications, or submit credentials through fraudulent authentication pages.

Singapore-based Ahsay Backup has released security updates to address two security flaws in AhsayCBS that have been exploited by bad actors to drop web shells and XMRig cryptocurrency miners. The vulnerabilities in question are CVE-2026-105133 and CVE-2026-105134 , which could be chained to sidestep authentication and execute arbitrary commands on affected systems. In a report published earlier this month, Huntress said it observed threat actors combining the two flaws to achieve unauthenticated remote code execution and deploy web shells and cryptocurrency miners on exposed systems. Although the vulnerabilities were initially assumed to be addressed in AhsayCBS versions 9.15.2.59 and 10.3.4.0 released in August 2026, the software company has now confirmed that the patches did not completely plug them. The fixes are available in the following versions - AhsayCBS v10.3.4.45 hotfix AhsayCBS v9.15.2.70 hotfix "Given the severity of these risks, we strongly urge ...

Attackers exploited a flaw in an optional Nextcloud app,  Collabora Online - Built-in CODE Server , to plant web shells on Nextcloud servers. Three administrators  reported the issue on GitHub , with the first logged attack on September 10. A web shell is a small file that executes any command an attacker sends via a web request, with the rights of the web server account. The flaw allows an unauthenticated request to run a command on the server, but only when the app's local document server is not running, such as during a restart or upgrade, or after a crash. Collabora fixed it in  version 26.4.303  on September 11 and on October 14 published  an advisory  with the identifier  CVE-2026-110447 , warning that turning off the app does not help: it must be updated or removed. Who Is Affected The app, published by Collabora under the package name richdocumentscode, downloads a copy of Collabora Online Development Edition (CODE) and runs it ...

Cybersecurity researchers have disclosed details of a new Android banking trojan called Hirudo that works by replacing legitimate banking apps with purpose-built patched versions designed to bypass security checks from inside the app itself, marking a new escalation in financial fraud.  Dutch mobile security company ThreatFabric said it identified replacements for eight Indonesian banking apps, while credential targeting in the malware spans Indonesia, China, India, Mexico, Morocco and Thailand. "The operation combines credential theft, device takeover, screen and camera capture, and SMS theft, in combination with a fairly mature backend," Eward Driehuis, vice president of fraud engineering at ThreatFabric, said in a statement shared with The Hacker News. Hirudo facilitates on-device credential theft and live remote control. The malware is delivered by shopping, adult video, and entertainment dropper apps that carry the trojan as a separate installation package, whic...

Small artificial intelligence (AI) models may be months away from developing capabilities to self-replicate on IoT devices like smart ovens and off-brand Android TV boxes, according to a warning from Anthropic. The frontier AI lab said small AI models could form autonomous, self-propagating worm botnets that are "challenging to shut down," since "there's no centralized point to shut off." Prior work has demonstrated that AI agents can act like one by scanning their network, executing an exploit, and copying model weights to a target machine across a GPU cluster with an aim to generate tailored attack strategies and use compromised machines as a botnet to run large language models (LLMs) in order to sustain its reasoning and expand in scale. "Such an 'AI worm' could carry its model weights with it as it reproduces (or re-download them from a public hub), and then run inference directly on compromised hardware," Anthropic said . "Eff...
