Fake sites to disguise malware delivery campaigns are among the top tactics of cyber adversaries. A hacker group was found running malicious campaigns to infect potential victims with DarkTortilla. For now, they are luring users via spam email or online ads. In another headline from the weekend, we have a security update from the Samba Team which addressed security holes across multiple versions of the free SMB implementation protocol. Hackers abusing these flaws could find a way to dominate the impacted systems.

It’s alive and kicking! The Glupteba botnet malware—that Google disrupted in 2021—is still prevalent. Recent reports suggest that it has been hiding its C&C domains on the Bitcoin blockchain. It took them about six months to launch a new campaign.

Australia’s fire and rescue service targeted
Cybercriminals knocked the website of Fire Rescue Victoria (FRV), Australia, offline, affecting most of its systems, such as network, emails, and dispatch infrastructure.

Phishing campaign drops DarkTortilla
Security analysts at Cyble observed two phishing sites imitating Grammarly and Cisco to distribute the DarkTortilla malware. The malware is capable of adding more RAT and stealer payloads, such as AgentTesla, AsyncRAT, NanoCore, and others to an infected system. The complex .NET-based malware has been operating since 2015.

Glupteba botnet is alive
Experts at Nozomi Networks announced that they spotted an ongoing Glupteba botnet campaign, starting June 2022. Just a year ago, Google had claimed to dismantle the botnet’s infrastructure. Glupteba operators used the Bitcoin blockchain for hiding C&C domains, making it resilient to takedown efforts. It took cybercriminals roughly six months to build a new campaign.
