ZDI-26-666: Adobe Acrobat Reader DC JPEG2000 File Parsing Out-Of-Bounds Read Information Disclosure Vulnerability
ZDI advisory ZDI-26-666 details an out-of-bounds read (CVE-2026-79910) when Adobe Acrobat Reader DC parses JPEG2000 files.
The Zero Day Initiative published advisory ZDI-26-666 for an out-of-bounds read triggered when Acrobat Reader DC parses JPEG2000 files. Successful exploitation allows a remote attacker to disclose sensitive information from affected installations. User interaction is required, such as opening a malicious file or visiting a malicious page. ZDI rated the issue 3.3 and assigned CVE-2026-79910.
Forgery of C2PA on a Pixel 10
Researcher forged a Google Pixel 10 C2PA content credential with genuine signatures, showing root-level attackers can fake photo provenance.
A Hacker Factor blog post demonstrates an AI-generated 'unicorn glitter milk' news photo carrying a valid, cryptographically signed C2PA manifest traceable to Google's Pixel camera certificate chain, passing validation in Adobe Inspect and the CAI Verify tool with a verified timestamp. The author, working with UMBC's PASAWG working group, reported to Google and C2PA in November 2025 that root access on a Pixel device could sign arbitrary images as camera captures; after 90 days without resolution, details were published. The finding undermines C2PA Assurance Level 2 claims made for Pixel 10 Content Credentials.
Decline in Rig Exploit Kit
Rig exploit kit activity dropped roughly 75% after the pseudo-Darkleech and EITest campaigns stopped using EKs, reflecting an overall decline in exploit kit activity.
Rig EK activity fell sharply in 2017: the pseudo-Darkleech campaign disappeared at the end of March, cutting Rig traffic about 50%, and the EITest campaign switched to tech support scams in late April, cutting another 50% in May. Broader causes include a shrinking browser target base, no major EK zero-day in over a year, and community takedowns of domain shadowing infrastructure. Criminals are shifting to malspam, social engineering schemes like fake HoeflerText notifications, and tech support scams.
