Today Adobe disclosed a new Flash zero-day, releasing a patch for the critical vulnerability in an out-of-band update. Successful exploitation gives attackers the ability to execute arbitrary code on the targeted machine, and eventually assume full system control. Morphisec customers are already protected from attacks exploiting this vulnerability.
Note: This post was updated 11-30-18 with details of a new intercepted attack. See technical description below.
Over the past three days, Morphisec Labs researchers have discovered a widespread cyber campaign hitting multiple targets. Morphisec researchers dubbed the campaign “Pied Piper”as it delivers various Remote Access Trojan (RAT) payloads via phishing, across multiple countries.

Careless Employee Behavior During the Online Holiday Shopping Season Will Leave Organizations Exposed to a Higher Risk of Cyber Attacks
The holiday season is fraught with consumer fraud. Holiday shoppers - both in-store and online - open themselves up to substantially higher risk without even knowing it.
However, what doesn’t get as much attention is the vulnerabilities that are created within enterprise organizations. Meaning, when employees choose to use work-issued devices and

It seems like the rumors of FIN7’s decline have been hasty. Just a few months after the well-publicized indictment of three high-ranking members in August, Morphisec has identified a new FIN7 campaign that appears to be targeting the restaurant industry.
Fileless malware is a type of a malicious code execution technique that operates completely within process memory; no files are dropped onto the disk. Without any artifacts on the hard drive to detect, these attacks easily evade most security solutions.
On March 21,2018, Morphisec Labs began investigating the compromised website of a leading Hong Kong Telecommunications company after being alerted to it by malware hunter @PhysicalDrive0. The investigation, conducted by Morphisec researchers Michael Gorelik and Assaf Kachlon, determined that the Telecom group's corporate site had indeed been hacked. Attackers added an embedded Adobe Flash file that exploits the Flash vulnerability CVE-2018-4878 on the main home.php page.
These days, most malware employs a long attack chain with anti-analysis techniques to make it more difficult to detect the payload and harder to analyze by security researchers. More and more frequently, they are also incorporating coin miners in attacks. Such is the case with a newly observed variant of the Dofoil (also known as Smoke Loader) trojan, which includes a resource-draining cryptocurrency-mining payload. This latest Dofoil strain entered the scene earlier this month and is currently still active.
On February 22, 2018, Morphisec Labs spotted several malicious word documents exploiting the latest Flash vulnerability CVE-2018-4878 in the wild in a massive malspam campaign. Adobe released a patch early February, but it will take some companies weeks, months or even years to rollout the patch and cyber criminals keep developing new ways to exploit the vulnerability in this window.
Before diving into the analysis of CVE-2018-4878, a quick reminder that this is the continuation of our previous post, which provided background on CVE-2018-4878, including a video of how Morphisec prevents any attacks leveraging this Flash vulnerability. Morphisec prevents the attack at all phases and components in the attack chain – during the exploit, the shellcode, as well as the malware which is executed using wbscript.exe with additional in-memory command control code.
At the time of the previous post, the vulnerability was still a zero-day. Adobe released a new version that fixed the flaw yesterday. With that fix available, Morphisec is now free to release technical details of the attack.
