Cybersecurity researchers have discovered a new zero-day vulnerability in Adobe Flash Player that hackers are actively exploiting in the wild as part of a targeted campaign appears to be attacking a Russian state health care institution. The vulnerability, tracked as CVE-2018-15982 , is a use-after-free flaw resides in Flash Player that, if exploited successfully, allows an attacker to execute arbitrary code on the targeted computer and eventually gain full control over the system. The newly discovered Flash Player zero-day exploit was spotted last week by researchers inside malicious Microsoft Office documents, which were submitted to online multi-engine malware scanning service VirusTotal from a Ukrainian IP address. The maliciously crafted Microsoft Office documents contain an embedded Flash Active X control in its header that renders when the targeted user opens it, causing exploitation of the reported Flash player vulnerability. According to cybersecurity researchers, neit...

If you have already uninstalled Flash player, well done! But if you haven't, here's another great reason for ditching it. Adobe has released a security patch update for a critical vulnerability in its Flash Player software that is actively being exploited in the wild by hackers in targeted attacks against Windows users. Independently discovered last week by several security firms—including ICEBRG ,  Qihoo 360  and Tencent—the Adobe Flash player zero-day attacks have primarily been targeting users in the Middle East using a specially crafted Excel spreadsheet. "The hackers carefully constructed an Office document that remotely loaded Flash vulnerability. When the document was opened, all the exploit code and malicious payload were delivered through remote servers," Qihoo 360 published vulnerability analysis in a blog post. The stack-based buffer overflow vulnerability, tracked as CVE-2018-5002, impacts Adobe Flash Player 29.0.0.171 and earlier versions on ...

Everybody knows browser extensions are embedded into nearly every user's daily workflow, from spell checkers to GenAI tools. What most IT and security people don't know is that browser extensions' excessive permissions are a growing risk to organizations. LayerX today announced the release of the Enterprise Browser Extension Security Report 2025 , This report is the first and only report to merge public extension marketplace statistics with real-world enterprise usage telemetry. By doing so, it sheds light on one of the most underestimated threat surfaces in modern cybersecurity: browser extensions. The report reveals several findings that IT and security leaders will find interesting, as they build their plans for H2 2025. This includes information and analysis on how many extensions have risky permissions, which kinds of permissions are given, if extension developers are to be trusted, and more. Below, we bring key statistics from the report. Highlights from the Enterprise Browse...

FinSpy —the infamous surveillance malware is back and infecting high-profile targets using a new Adobe Flash zero-day exploit delivered through Microsoft Office documents. Security researchers from Kaspersky Labs have discovered a new zero-day remote code execution vulnerability in Adobe Flash, which was being actively exploited in the wild by a group of advanced persistent threat actors, known as BlackOasis . The critical type confusion vulnerability, tracked as CVE-2017-11292 , could lead to code execution and affects Flash Player 21.0.0.226 for major operating systems including Windows, Macintosh, Linux and Chrome OS. Researchers say BlackOasis is the same group of attackers which were also responsible for exploiting another zero-day vulnerability ( CVE-2017-8759 ) discovered by FireEye researchers in September 2017. Also, the final FinSpy payload in the current attacks exploiting Flash zero-day (CVE-2017-11292) shares the same command and control (C&C) server as the...
