Flubot: the evolution of a notorious Android Banking Malware
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
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
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 […]

Unpacking RDStealer: An Exfiltration Malware Targeting RDP Workloads
Unpacking RDStealer: An Exfiltration Malware Targeting RDP Workloads
In June 2023, Bitdefender Labs published a research paper about espionage operation in East Asia. This operation was ongoing since at least the beginning of 2022, showing a high level of sophistication typically associated with state-sponsored groups. Despite trying various methods, we have been unable to attribute these attacks to a specific threat actor, but the target aligns with the interest of China-based threat actors.

COSMICENERGY: New OT Malware Possibly Related To Russian Emergency Response Exercises | Mandiant
COSMICENERGY: New OT Malware Possibly Related To Russian Emergency Response Exercises | Mandiant
Mandiant identified novel operational technology (OT) / industrial control system (ICS)-oriented malware, which we track as COSMICENERGY, uploaded to a public malware scanning utility in December 2021 by a submitter in Russia. The malware is designed to cause electric power disruption by interacting with IEC 60870-5-104 (IEC-104) devices, such as remote terminal units (RTUs), that are commonly leveraged in electric transmission and distribution operations in Europe, the Middle East, and Asia.

Justice Department Announces Court-Authorized Disruption of the Snake Malware Network Controlled by Russia's Federal Security Service
Justice Department Announces Court-Authorized Disruption of the Snake Malware Network Controlled by Russia's Federal Security Service
“Russia used sophisticated malware to steal sensitive information from our allies, laundering it through a network of infected computers in the United States in a cynical attempt to conceal their crimes.  Meeting the challenge of cyberespionage requires creativity and a willingness to use all lawful means to protect our nation and our allies,” stated United States Attorney Peace.  “The court-authorized remote search and remediation announced today demonstrates my Office and our partners’ commitment to using all of the tools at our disposal to protect the American people.”

Hunting Russian Intelligence “Snake” Malware
Hunting Russian Intelligence “Snake” Malware
The Snake implant is considered the most sophisticated cyber espionage tool designed and used by Center 16 of Russia’s Federal Security Service (FSB) for long-term intelligence collection on sensitive targets. To conduct operations using this tool, the FSB created a covert peer-to-peer (P2P) network of numerous Snake-infected computers worldwide. Many systems in this P2P network serve as relay nodes which route disguised operational traffic to and from Snake implants on the FSB’s ultimate targets. Snake’s custom communications protocols employ encryption and fragmentation for confidentiality and are designed to hamper detection and collection efforts.
