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.Read More
Morphisec researchers Michael Gorelik and Andrey Diment have discovered CIGslip, a new method which can be exploited by attackers to bypass Microsoft’s Code Integrity Guard (CIG) and load malicious libraries into protected processes such as Microsoft Edge.Read More
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.Read More
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.Read More
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.Read More
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.Read More
The IT world is still shaking from the news that most modern processors have severe architecture flaws. This makes it possible for attackers to gain access to user mode and kernel memory data to leak crypto-keys, passwords, memory structures like loaded module addresses and other valuable information. The security flaws potentially affect all major CPUs, including chips manufactured by Intel, AMD and ARM.
Watch our security alert webinar on-demand in which Morphisec CTO Michael Gorelik, cuts through the noise surrounding the Meltdown and Spectre CPU vulnerabilities and answers live questions.
A report co-authored by Michael Gorelik, CTO and VP R&D, and Roy Moshailov, Malware Research Expert at Morphisec.
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 current detection solutions.Read More
