Solving the 7777 Botnet enigma: A cybersecurity quest
Sekoia.io investigated the mysterious 7777 botnet (aka. Quad7 botnet), published by the independent researcher Gi7w0rm inside the “The curious case of the 7777 botnet” blogpost. This investigation allowed us to intercept network communications and malware deployed on a TP-Link router compromised by the Quad7 botnet in France. To our understanding, the Quad7 botnet operators leverage compromised TP-Link routers to relay password spraying attacks against Microsoft 365 accounts without any specific targeting. Therefore, we link the Quad7 botnet activity to possible long term business email compromise (BEC) cybercriminal activity rather than an APT threat actor. However, certain mysteries remain regarding the exploits used to compromise the routers, the geographical distribution of the botnet and the attribution of this activity cluster to a specific threat actor. * The insecure architecture of this botnet led us to think that it can be hijacked by other threat actors to install their own implants on the compromised TP-Link routers by using the Quad7 botnet accesses.

You can hide data in directory structures, and it will be more or less invisible without knowing how to decode it. It won't even show up as taking up space on disk. However, its real-world applications may be limited because it is the code execution itself which is often the difficulty with AV/EDR evasion.

Special Report: Massive Global IT Outages Triggered by Faulty CrowdStrike Update
Cascading and catastrophic IT outages have hit thousands of organizations worldwide after CrowdStrike issued a faulty update in its Falcon Sensor product that caused Windows operating systems to crash.
In collaboration with Google’s Threat Analysis Group (TAG), Mandiant has observed a sustained campaign by the advanced persistent threat group APT41 targeting and successfully compromising multiple organizations operating within the global shipping and logistics, media and entertainment, technology, and automotive sectors. The majority of organizations were operating in Italy, Spain, Taiwan, Thailand, Turkey, and the United Kingdom. APT41 successfully infiltrated and maintained prolonged, unauthorized access to numerous victims' networks since 2023, enabling them to extract sensitive data over an extended period. APT41 used a combination of ANTSWORD and BLUEBEAM web shells for the execution of DUSTPAN to execute BEACON backdoor for command-and-control communication. Later in the intrusion, APT41 leveraged DUSTTRAP, which would lead to hands-on keyboard activity. APT41 used publicly available tools SQLULDR2 for copying data from databases and PINEGROVE to exfiltrate data to Microsoft OneDrive
