As of January 10th 2023, Windows 7, Windows 8, 8.1, their Windows embedded derivatives, and Windows Server 2008 R2 will no longer receive patches from Microsoft. Millions of devices will now become "legacy" and create a suite of new legacy security...

Ransomware attacks have undergone a pandemic-accelerated evolution in recent years—and defenses have struggled to keep up. The first phase of ransomware has given way to something new and different, better and worse. To help understand this...

Today’s cyber security solutions aren’t countering threat actors’ advanced attacks. In the wake of the SolarWinds breach, even the largest companies and most-secure public agencies have had serious vulnerabilities exposed. If existing solutions...

On December 9th, 2021, reports surfaced about a new zero-day vulnerability, termed Log4j (Log4Shell), impacting Minecraft servers. [see “Protecting Against the Log4J Vulnerability”] Countless millions of devices instantly became at risk of attack,...

With a year-on-year increase of over 161%, malicious usage of cracked versions of Cobalt Strike (a legitimate penetration test tool) is skyrocketing. For organizations that still rely on signature-based next generation antivirus (NGAV) solutions to...

On December 9th, 2021, reports surfaced about a new zero-day vulnerability, termed Log4j (Log4Shell), impacting Minecraft servers. Now, almost one week later, it is clear that countless millions of devices are at risk, and Log4j may rank among the...

Ransomware attacks are soaring. By the end of this year, the global costs incurred by ransomware will be more than $20 billion annually – 57 times what they were in 2015 . For individual organizations feeling the sharp end of this exponential rise,...

Almost a year after an international law enforcement effort supposedly defeated it, Emotet, aka "the world's most dangerous botnet," has returned. Earlier this week, German security researcher Luca Ebach reported seeing malware with Emotet-like...

In the past month, Morphisec has investigated the origin of several increasingly prevalent infostealers. These include Redline, Taurus, Tesla, and Amadey.

As part of our research, we identified pay-per-click (PPC) ads in Google’s search results that...

The developers of the Phobos ransomware have added new fileless and evasive techniques to their arsenal. Constantly keeping their attack up to date helps them bypass detection technologies through several distinct approaches, the latest of which we...

Microsoft recently published details of an attack showing how a threat actor used zero-day exploits to access Microsoft Exchange Servers. The new exploit enabled access to email accounts and allowed the installation of additional malware to...

Introducing egregor ransomware

Egregor is considered to be one of the most prolific ransomware threat groups. Yet it gained this reputation in a very short time due to its uncompromising double extortion methodology.

Introduction

The Agent Tesla information stealer has been around since 2014. During the last two to three years, it's also had a significant distribution growth factor partially due to the fact that cracked versions of it have been leaked.

Garmin has confirmed that the recent outage its users experienced was indeed the result of a successful ransomware attack. However, the extent of the damage done is still unclear. The attack, which compromised Garmin’s servers for five days,...

Advanced persistent threats describes the highly evolved nature of today’s cyberattacks. Hackers have developed sophisticated techniques – in-memory exploits, living-off-the-land attacks, remote access trojans, and more – that allow them to evade...

Since early March, the team at Morphisec Labs has been supporting enterprises as they shift to distributed workforces in response to COVID-19. From assisting hospitals with securing their remote workers to uncovering new weaknesses in collaboration...

As part of a rapid change in the work environment during the COVID-19 pandemic, Morphisec Labs has been tracking the change in the attack trend landscape. This has included the evolution of adware, PUA, and fraudulent software bundle delivery beyond...

The rise of fileless attacks in the past 10 years has stymied even the best antivirus software. Traditional AV is designed to detect known signatures of known malware and prevent it from executing. Fileless attacks lack a signature, which allows it...

EDITOR'S NOTE: The previous version of this blog post mis-identified the source of this attack as the FIN7 group; GRIFFON and OSTAP are both very long javascripts that have many similarities. This caused the confusion in identifying the attack as...
