Adobe Acrobat Flaw Lets Hackers Steal WhatsApp Data | HermeticReader Explained [CVE-2026-48294] (2026)
A newly reported Adobe Acrobat weakness could let criminals use a booby-trapped PDF file to reach into WhatsApp and steal private messages or shared information from a device. This means opening an unsafe document could put personal conversations and sensitive attachments at risk.
Who is at risk
Anyone who uses Adobe Acrobat to open PDF files and also uses WhatsApp on the same device is most at risk, especially if they receive documents from people they do not know well.
What to watch for
Watch for unexpected PDF files, messages urging you to open an attachment quickly, or unusual behavior after opening a document, such as WhatsApp acting strangely or files appearing you do not recognize.
What to do
Update Adobe Acrobat right away, avoid opening unexpected PDF attachments, and if you already opened a suspicious file, close Acrobat, update your device and apps, and review WhatsApp for unusual activity.
