What is Adobe Flash?

Adobe Flash Player

Adobe Flash is an extremely popular plug-in that enables users to access video, audio and multimedia content online as well as Rich Internet Applications. It is available for desktop operating systems such as Windows, Linux and Mac OS X.

Adobe Flash can display both raster and vector graphics, text, sound and video. It features its own proprietary ActionScript scripting language for scripting the applications as well as support for various data formats.

Web browsers

Adobe Flash Player, previously Macromedia Flash, is a Web application that enables you to see animations and videos online. As a plugin for most major browsers, Adobe Flash Player displays these elements when visiting websites.

Flash was once popular with video streaming websites and gaming websites alike, and was an essential component of Web applications in general. But as technology advanced and new formats developed to work on mobile devices, these websites and applications began shifting away from using Flash as their content delivery method – sometimes completely abandoning it in favor of HTML5 alternatives instead.

Adobe Flash has long been targeted by hackers looking to take advantage of security holes within its software. Due to this vulnerability, many browser makers have stopped supporting it or blocked it outright.

Chrome and Safari browsers, for instance, can render Flash without needing an additional plugin. This technique is known as native mode; browsers do this using an HTML5 framework which renders graphics and animation on-demand.

Other browsers, like Firefox and Internet Explorer, require a separate plugin in order to use Flash content – known as “embedded mode.” As these browsers cannot natively display Flash media content themselves, they rely on this separate plugin in order to play this material.

Adobe has officially discontinued supporting Flash in 2021, and many browsers have blocked its functionality as a result. If you still use it, Adobe strongly advises uninstalling all versions as these will no longer receive security updates.

Due to this change, nefarious actors who may have discovered exploits in older products will no longer be able to patch them, leaving your systems exposed. We recommend performing a quick audit of any websites, portals or experiences you use with respect to Flash content replacement with more modern options like HTML5. On Windows machines this should happen automatically through updates.

Mobile devices

Adobe has recently announced its plans to end Flash Player support for mobile devices and instead transition towards HTML5, the emerging Web standard. This move marks an end to 15-year-old technology once dominating multimedia delivery and applications execution on the Web; but isn’t surprising given that Apple CEO Steve Jobs has long criticized Flash Player, alleging it reduces battery life and is vulnerable to security breaches.

Adobe’s announcement comes nearly one month after Apple began blocking Flash on iPhones, prompting many content providers to abandon Flash as a platform. Adobe believes HTML5, which can deliver similar content without needing separate plugins, provides them an alternative.

Adobe announced its new strategy by aggressively contributing to HTML5, while continuing to offer developers a platform with the best experience possible. Adobe will keep developing Flash Player for desktop operating systems while pushing developers toward content creation in its AIR software that runs like native applications on devices.

Flash Player 10.2 has made its debut on the Android Market as of 18 March, featuring hardware acceleration for H.264 video and improved Flash rendering on phones and tablets, such as smoother scrolling. Furthermore, JPEG-XR advanced image compression standard – providing higher quality compression than JPEG while offering alpha channel transparency capabilities – was added as well.

Phones running Android 2.2 Froyo or 2.3 Gingerbread generally come equipped with Flash Player preinstalled; however, users of Motorola Droid X and other tablets running Android 3.0 Honeycomb must upgrade to 10.2 before being able to get it. Palm’s Pre range of phones under HP’s logo will also support Flash, though this update won’t reach other smartphones worldwide for some time – Flash Player requires at least one dual-core ARM Cortex-A9 processor with at least 550MHz clock speed if it can run properly on phones running Android 3.0 Honeycomb 3.0 Honeycomb in order to run properly.

Operating systems

Adobe Flash Player was once the go-to software for multimedia websites like video streaming platforms and online gaming sites, such as Shockwave Flash or Macromedia Flash, but its vulnerability to attack by hackers meant many people and businesses were opting out altogether or even completely disabling it from their computers. Due to these flaws, many individuals and companies avoided visiting Flash-related websites altogether or decided to uninstall Adobe Flash from their machines altogether.

Adobe has continually expanded and developed Flash since its initial use as an authoring tool to become a comprehensive platform. Through Breeze and Flex 1.0 tools, developers were able to use it to create user interfaces (GUIs) and applications for mobile phones, desktop computers and servers; viewers of which could then access these via the Flash player or standalone plug-ins or browser plug-ins such as Silverlight or Flash player itself; Flash also allowed playback of video in FLV or F4V format, accessible either by end users via web browser or directly via HTTP progressive download from servers using HTTP progressive download technology.

Artists use Adobe Flash Application Files (FLAs) to produce Flash graphics and animations. These editable files can then be converted to SWF movie files for viewing in the Flash player, where they are playable on multiple platforms including bitmap images, audio streams encoded to MPEG-2 Audio Layer III standards or Advanced Audio Coding specifications as well as FLV or F4V video formats with hardware acceleration that makes use of codec chipsets installed on computers or mobile devices.

In 2011, Adobe Flash Player unveiled Stage3D, offering GPU-accelerated 3D rendering for games and other applications. In 2013, this was further enhanced with alpha channels, compressed textures, and texture atlases being introduced. Flash apps can be built using Adobe Flash Builder/Develop or ActionScript 3.0 scripting languages like CrossBridge to access C/C++ compilers such as LLVM/GCC or high performance memory access opcodes within its Flash player environment.


Back before Google (BG), personal computers were experiencing a seismic shift. With CD-ROM technology enabling users to install multimedia applications containing video, audio and animation onto their machines, Macromedia took full advantage of this new capability by creating a tool to assist with application creation; eventually this became known as Adobe Flash and quickly gained widespread acclaim.

Adobe Flash is a multi-platform software application that enables users to play various media formats on desktop computers, laptops and mobile devices. Adobe Flash is well-known for its real-time video rendering ability – an ideal medium for live content delivery – however many vulnerabilities have been found within Adobe Flash which hackers exploit to hijack browsers, launch phishing attacks against users or steal their data.

Searches of the National Vulnerability Database reveal Adobe Flash as being plagued with multiple security flaws, with several receiving the highest rating based on impact and severity. Cyber criminals could exploit vulnerable files of Adobe Flash to launch XSS attacks against unsuspecting computers using them to launch phishing or malicious websites, redirect visitors away from legitimate ones and even take over browsers in order to steal users’ passwords.

Flash has long been known for reporting detailed information about computer and operating system configuration to third-party websites that collect this data for spying and fingerprinting purposes. Adversaries have used such information against individuals – known as fingerprinting – while bad actors use fake Adobe Flash Player updates notifications to lure victims into installing malware.

Adobe releases security updates to their Flash program in order to address vulnerabilities such as hackers controlling it remotely, yet malicious actors often try to disguise their own software as updates for Adobe programs making it hard for ordinary users to distinguish legitimate from harmful software.

Users concerned about security threats can download and install the most up-to-date version of Adobe Flash or choose an alternative media player when watching videos. Furthermore, keeping browser updates current may help protect them against many vulnerabilities similar to those in Adobe Flash itself.
