New Adobe Flash zero-day exploit discovered in malvertisements
Authored by a Symantec employee
A new Adobe Zero-day exploit was discovered by Trend Micro on February 2nd, 2015. A Zero-day exploit is when there is an unpatched bug in a software program that allows hackers access to inject malware into your computer.
A security suite that helps protect your devices.
Free security software just doesn’t have the resources to keep up with new threats as they emerge. That’s why you need a multi-layered defense to security. Meet Norton Security Premium — protection for up to 10 of your devices.
How can cybercriminals infect my system?
In this particular case, the malware is delivered via malvertising, which is a form of an attack that uses legitimate online advertising networks to deliver malicious code onto your computer. Unfortunately, you don’t even have to do anything to be infected by this kind of malvertising, as it often uses a drive-by-download; where all a user has to do to contract the malware is to visit the infected webpage or be redirected to a compromised site.
Does this issue affect me?
Adobe has acknowledged this new vulnerability and has stated the following versions are affected:
- Adobe Flash Player 220.127.116.116 and earlier versions for Windows and Macintosh
- Adobe Flash Player 18.104.22.1684 and earlier 13.x versions
- Adobe Flash Player 22.214.171.1240 and earlier versions for Linux
Adobe has also stated that a patch will be available some time this week. The vulnerability is currently unpatched.
This is the second vulnerability that comes a week after the discovery of the Angler Exploit Kit. It is important to note that Flash users who applied the newly released software update from Adobe last week for the Angler Exploit Kit will still be exposed to this new vulnerability.
