Adobe fixes PDF zero-day security bug that hackers have exploited for months

Adobe has patched a vulnerability in its flagship document-reading apps, Acrobat DC, Reader DC and Acrobat 2024, that hackers have been actively exploiting for at least four months.

The vulnerability, officially tracked as CVE-2026-34621, allows hackers to remotely plant malware on a person’s device by tricking them into opening a maliciously crafted PDF file on their Windows device or macOS computer. The exploit targets a vulnerability in some versions of the Adobe Reader software.

It is not yet known how many people have been affected by this hacking campaign. In a note on its website, Adobe said it was aware that the bug is being exploited in the wild, known as a zero-day, indicating that hackers have been using it to break into people’s computers before Adobe could fix it. 

While it’s not clear who is behind the hacking campaign, the ubiquity of Adobe’s PDF-reading software makes it a consistent target for cyber criminals and government-backed hackers, who have long abused weaknesses in the software to steal data from people’s computers.

Security researcher Haifei Li, who runs the exploit-detection system EXPMON, discovered the vulnerability after someone uploaded a copy of a malicious PDF containing the exploit to his malware scanner. In a blog post, Li wrote that another copy of the malware-ridden PDF first appeared on VirusTotal, another online malware scanner, in late November 2025.

It’s not clear who the hacking campaign was targeting or for what reason, and Li said it was not possible to obtain any additional exploits from the hacker’s servers. But according to Li’s analysis, opening a malicious PDF and triggering the exploit “could lead to full control of the victim’s system” and give the hacker the ability to steal a wide range of data.

Adobe said Acrobat DC, Reader DC, and Acrobat 2024 are affected, and urged users to update their software to the latest versions.

Tesla adds ‘streaks’ and other stats to track how often drivers use Full Self-Driving software

Tesla adds ‘streaks’ and other stats to track how often drivers use Full Self-Driving software

The company teased the redesigned self-driving app, along with a slew of other new features that will be included in its next major software update, in a post on X.

Tesla’s Full Self-Driving (Supervised) is an advanced driver assistance system that launched in beta in late 2020, and has had regular subsequent updates to remove bugs, improve reliability, and performance. The system — available with a $99 monthly subscription — handles driving maneuvers such as steering, lane changes, and parking. FSD still requires active driver supervision, which means vehicles equipped with the software are not autonomous.

Tesla CEO Elon Musk is trying to position the company as an AI and robotics powerhouse, not just an automaker. FSD is part of that mission. Hitting “10 million active FSD subscriptions” by 2035 is one of the key “product goals” required for Musk to receive the full payout of his new $1 trillion pay package.

The new app will let owners subscribe in one tap. A caveat is that the feature is only available to owners of Tesla vehicles with the A14 chip, also known as FSD Hardware 4.0, which began shipping in vehicles in January 2023.

Once accessed, the updated self-driving app will display a variety of stats that go far beyond what Tesla owners with FSD see today. Current FSD subscribers see the total number of miles driven compared to the percentage driven using FSD.

This latest update will display a couple of graphics, including the FSD usage in a bar chart. It will also track and display user “streaks,” for consecutive days FSD is used.

FSD (Supervised) is available in the Australia, Canada, China, Mexico, New Zealand, Puerto Rico, South Korea and the United States. Dutch regulator RDW approved the use of FSD on April 10 after researching and testing the product.

Instacart acquires Instaleap to expand its enterprise platform internationally

Instacart has acquired Colombia-based grocery tech firm Instaleap, the company announced on Tuesday. The financial terms of the deal were not disclosed.

Founded in 2019, Instaleap is a global fulfillment solutions platform that helps retailers streamline and scale their online operations. The company has clients across nearly 30 countries in Latin America, Europe, and the Middle East.

While Instacart is mostly known for grocery delivery, it’s been investing in retail technology and fulfillment services over the past several years. Its commerce platform, Storefront Pro, powers the e-commerce operations of more than 380 grocers, including Aldi, Costco, Publix, and Sprouts. Additionally, its Carrot Ads offering allows more than 310 retailers to build and scale their online and in-store advertising business.

Given that Instacart’s delivery service is only available in North America, the acquisition will allow the company to expand its business into international markets without needing to launch a delivery network in those regions.

Instaleap will initially operate as a wholly-owned subsidiary of Instacart, the company says. Instacart plans to expand more of its own enterprise technology to Instaleap’s partners over time.

“We see a meaningful opportunity to expand internationally through an enterprise-led strategy that empowers retailers across the globe to meet the evolving omnichannel needs of their customers,” said Ryan Hamburger, Chief Commercial Officer at Instacart, in a statement. “With the addition of Instaleap’s technology, international expertise, and deep retail relationships, we can accelerate our international expansion and better serve retailers and consumers around the world.”

“We’ve built our platform with a deep focus on the unique needs of grocery retailers across diverse international markets,” said Instaleap co-founder and CEO Antonio dos Santos Nunes in a press release. “Joining Instacart enables us to scale our impact with the support of a trusted partner that shares our commitment to retailer success.”
