Posted by Michael Gorelik on March 23, 2018 at 2:01 PM


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.

Threat Profile: Dofoil (Smoke Loader) Trojan with Coin-Miner 

Posted by Roy Moshailov on March 22, 2018 at 2:08 PM


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.

Webinar: Dynamic Endpoint Protection for Virtual Environments

Posted by Tom Bain on March 20, 2018 at 7:35 AM

Register for our webinar Dynamic Endpoint Protection for Virtual Environments on March 21, 2018.

Virtual Desktop Infrastructure (VDI) offers many advantages but it is not attack proof and highly advanced cyberattacks present an ever growing threat. IT and Security teams need to rethink the fabric, the costs and the risks inherent within virtual environments. Endpoint protection for VDIs has always been problematic as they are extremely sensitive to the performance impact of security products. The wrong security tools will consume resources, slow system boot up and impede productivity.

The Lazarus Group Strikes Again - Or is it an Imposter? The Latest CVE-2018-4878 Attack

Posted by Michael Gorelik on March 2, 2018 at 9:13 AM

The Lazarus Group, also known as Hidden Cobra, may be in play again. The notorious cybercrime group is allegedly responsible for some of the most devastating attacks over the past few years, including the SWIFT network hack that stole $81 million Central Bank of Bangladesh issued and the 2014 destructive wiper attack against Sony Pictures. Some also link the WannaCry ransomware breakout to the same group.

Many of the existing reports covering the Lazarus attacks suggest links to North Korea. In fact, Hidden Cobra is the U.S. Government’s designation for malicious cyber activity conducted by the North Korean government.

On February 28, 2018, Morphisec Labs identified and prevented a suspicious document uploaded to VirusTotal that exploits the latest Flash vulnerability CVE-2018-4878. While analyzing the exploit and the downloaded payload, we immediately identified a near-perfect match to many of the techniques used during various attacks that are attributed to the Lazarus Group.

Flash Exploit, CVE-2018-4878, Spotted in The Wild as Part of Massive Malspam Campaign

Posted by Michael Gorelik on February 25, 2018 at 7:42 PM


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

Series B Funding Round Validates Morphisec’s Groundbreaking Cybersecurity Technology

Posted by Ronen Yehoshua on February 19, 2018 at 5:29 PM

When we founded Morphisec in 2014, it arose from the observation that too many endpoint protection solutions followed the same old paradigm, even if they were using more technologically sophisticated methods. We believed a fundamentally new approach was needed, one that looked from the point of view of the attacker.

We also firmly believed that cybersecurity should enable business, not hinder operations or interfere with business goals.

CVE-2018-4878: An Analysis of the Flash Player Hack

Posted by Michael Gorelik on February 8, 2018 at 2:30 PM


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.

Adobe Flash Zero-Day Prevented by Morphisec (CVE-2018-4878)

Posted by Michael Gorelik on February 6, 2018 at 4:10 PM

How an organization handles the time between the unleashing of a zero-day and the availability of a patch is telling. There are basically two kinds of companies – those that try to mitigate the risk as best they can while they wait for a patch and those that have a security tool able to prevent zero-days. The latest Flash-Player zero-day CVE-2018-4878 is yet another example.
