A newly discovered malware called SambaSpy is targeting users in Italy through a carefully planned phishing campaign. Researchers suspect that a group of Brazilian Portuguese-speaking hackers is behind this attack. While many cybercriminals aim to reach as many victims as possible, this group is focusing solely on Italy, possibly testing their methods before expanding to other countries like Brazil and Spain.
How the SambaSpy Attack Works
The attack starts with a phishing email, tricking users into either opening an HTML attachment or clicking an embedded link. Here’s how each path works:
HTML Attachment:
The email includes an attachment with an HTML file. If opened, it contains a ZIP archive with a downloader or dropper. These files are responsible for installing the SambaSpy Remote Access Trojan (RAT). The downloader retrieves the malware from a remote server, while the dropper extracts it from the archive on the user’s device.
Embedded Link:
This path is more elaborate. If the user is not the intended victim, clicking the link sends them to a legitimate website like FattureInCloud, which hosts invoices. However, targeted users—those using Edge, Firefox, or Chrome with Italian language settings—are sent to a malicious server. This server delivers a PDF from Microsoft OneDrive, instructing the user to click a link, leading them to a JAR file hosted on MediaFire, which then downloads the malicious downloader or dropper.
Samba digs it all, whether it is pasta, gelato or pizza
Once the SambaSpy RAT is active on a system, it can perform various harmful actions, including:
Controlling the file system and processes
Taking over the remote desktop
Uploading and downloading files
Accessing the webcam and capturing screenshots
Tracking keystrokes and clipboard content
Stealing browser credentials from browsers like Chrome, Edge, and Opera
Additionally, SambaSpy can load extra plugins to expand its capabilities as needed, making it a highly flexible and dangerous malware.
Expansion Beyond Italy
While Italy is the current focus, the hackers behind this campaign are showing signs of preparing to expand to Brazil and Spain. Researchers have found clues in the malware's code that connect it to Brazil, and it’s common for Latin American cybercriminals to target countries with similar languages, like Italy, Spain, and Portugal.
In parallel, other cybercriminal groups are also ramping up attacks in Latin America, with malware like BBTok, Grandoreiro, and Mekotio targeting users through phishing emails. These attacks often aim to steal banking credentials and use advanced techniques to avoid detection.
Brush up on your mambo before the samba comes: How to Protect Yourself
With the rise of sophisticated phishing campaigns like SambaSpy, it's important to take steps to protect yourself. Here are some key defenses:
Be Wary of Phishing Emails:
Always be cautious of unexpected emails, especially those with attachments or links. Look for signs like unusual senders, odd grammar, or slight spelling mistakes.
Enable Multi-Factor Authentication (MFA):
Add an extra layer of security to your accounts with MFA. Even if your login credentials are stolen, MFA can block unauthorized access.
Use Email Filtering Tools:
Set up filters to automatically detect and block suspicious emails, attachments, and links before they reach your inbox.
Keep Your Software Updated:
Ensure your browsers, operating systems, and other software are up to date. Outdated software is often vulnerable to attacks.
Educate Users:
Regularly train employees and users to recognize phishing emails and other potential threats. Simulated phishing tests can help improve their awareness.
Install Anti-Malware Software:
Use trusted anti-malware tools to detect and block malicious files. These programs can often identify harmful ZIP files or JAR files like those used by SambaSpy.
Control Browser Language Settings:
In some attacks, like SambaSpy, hackers target users with specific browser language settings. Limiting browser language options can reduce risk.
Monitor Web Traffic:
Use tools to monitor and block access to malicious websites. A Secure Web Gateway (SWG) can prevent users from visiting harmful URLs.
Sandbox Email Attachments:
Set up systems that automatically open email attachments in a safe, isolated environment (sandbox) to detect potential threats without exposing users.
