HP Inc. has issued its latest Threat Insights Report, with strong indications that attackers are using AI to scale and accelerate campaigns — with many prioritizing cost, effort and efficiency over quality. Despite being formulaic and low-effort, these AI-assisted attacks are slipping past enterprise defenses.

The report provides an analysis of real-world cyberattacks, helping organizations keep up with the latest techniques cybercriminals are using to evade detection and breach PCs in the fast-changing cybercrime landscape. Based on the millions of endpoints running HP Wolf Security, notable campaigns identified by HP Threat Researchers include:

• Vibe-Hacking Scripts Using Booking.com Redirects: Attackers are using AI to generate ready-made infection scripts — known as vibe-hacking — to automate malware delivery. In one campaign, a link within a fake invoice PDF triggers a silent download from a compromised site before redirecting victims to trusted platforms, like Booking.com.
• Flat-Pack Malware Speeds Up Campaign Building: Threat actors are assembling attacks using inexpensive, off-the-shelf malware components, likely purchased from hacker forums. While lures and final payloads change, attackers are reusing the same intermediate scripts and installers — allowing them to quickly build, customize and scale campaigns with minimal effort. Notably, this isn't the work of a single threat group; multiple, unrelated actors are using the same building blocks.
• Malware Hidden in Fake Teams Installer 'Piggyback' Attack: Campaigns distributed malware using search engine poisoning and malicious adverts that promote fake Microsoft Teams websites. Victims download a malicious installer bundle in which hidden Oyster Loader malware piggybacks on the Teams installation process, allowing the real app to install while the infection runs unnoticed — giving the attacker backdoor control of the user’s device.

"It's the classic project management triangle — speed, quality and cost," said Alex Holland, principal threat research, HP Security Lab. "You often sacrifice one of them. What we're seeing is many attackers are optimizing for speed and cost, not quality. They are not using AI to raise the bar; they're using it to move faster and reduce effort. The campaigns themselves are basic but the uncomfortable reality is they still work."

By isolating threats that have evaded detection tools on PCs — but still allowing malware to detonate safely inside secure containers — HP Wolf Security has insight into the latest techniques used by cybercriminals. To date, HP Wolf Security customers have clicked on more than 60 billion email attachments, web pages and downloaded files with no reported breaches.

The report, which examines data from October through December 2025, details how cybercriminals continue to diversify attack methods to bypass security tools with no reported breaches.

• At least 14% of email threats identified by HP Sure Click bypassed one or more email gateway scanners.
• Executable files were the most popular delivery type (37%), followed by .zip (11%) and .docx (10%).

"AI-assisted attacks are shining a spotlight on the limitations of detection-led security," said Dr. Ian Pratt, global head of security for personal systems, HP Inc. "When attackers can generate and repackage malware in minutes, detection-based defenses can't keep up. Instead of trying to spot every variant, organizations need to reduce exposure. By containing high-risk activities — like opening untrusted attachments or clicking unknown links — within an isolated environment, businesses can stop threats before they cause damage and remove an entire class of risk."
