DarkGate malware delivered via Microsoft Teams - detection and response
While most end users are well-acquainted with the dangers of traditional phishing attacks, such as those delivered via email or other media, a large proportion are likely unaware that Microsoft Teams chats could be a phishing vector. Most Teams activity is intra-organizational, but Microsoft enables External Access by default, which allows members of one organization to add users outside the organization to their Teams chats. Perhaps predictably, this feature has provided malicious actors a new avenue by which to exploit untrained or unaware users.

In both his twitter (err, X) thread and in a subsequent posting he provided a comprehensive background and triage of the malware dubbed SpectralBlur. In terms of its capabilities he noted: SpectralBlur is a moderately capable backdoor, that can upload/download files, run a shell, update its configuration, delete files, hibernate or sleep, based on commands issued from the C2. -Greg He also pointed out similarities to/overlaps with the DPRK malware known as KandyKorn (that we covered in our “Mac Malware of 2024” report), while also pointing out there was differences, leading him to conclude: We can see some similarities ... to the KandyKorn. But these feel like families developed by different folks with the same sort of requirements. -Greg

Flubot: the evolution of a notorious Android Banking Malware
Flubot is an Android based malware that has been distributed in the past 1.5 years in Europe, Asia and Oceania affecting thousands of devices of mostly unsuspecting victims. Like the majority of Android banking malware, Flubot abuses Accessibility Permissions and Services in order to steal the victim’s credentials, by detecting when the official banking application is open to show a fake web injection, a phishing website similar to the login form of the banking application. An important part of the popularity of Flubot is due to the distribution strategy used in its campaigns, since it has been using the infected devices to send text messages, luring new victims into installing the malware from a fake website. In this article we detail its development over time and recent developments regarding its disappearance, including new features and distribution campaigns.
BRATA is evolving into an Advanced Persistent Threat
Here we go with another episode about our (not so) old friend, BRATA. In almost one year, threat actors (TAs) have further improved the capabilities of this malware. In our previous blog post [1] we defined three main BRATA variants, which appeared during two different waves detected by our telemetries at the very end of 2021. However, during the last months we have observed a change in the attack pattern commonly used.
Linux Threat Hunting: 'Syslogk' a kernel rootkit found under development in the wild
Introduction Rootkits are dangerous pieces of malware. Once in place, they are usually really hard to detect. Their code is typically more challenging to write than other malware, so developers resort to code reuse from open source projects. As rootkits are very interesting to analyze, we are always looking out for these kinds of samples […]
