Tesla has often made headlines lately, but this new problem is not connected to Elon Musk or his cars. Instead, it involves cybercriminals who are trying to steal people’s private information using a dangerous software called Agent Tesla.
Here’s a clear explanation of how the attack works and what you need to stay safe.
Attackers Use Clever Tricks to Spread Malware
Researchers from Unit 42, the security team at Palo Alto Networks, have reported a new online threat. This time, hackers are sending fake emails to people, pretending that important documents like invoices or payment receipts are attached.
When someone opens the file, it quietly triggers a hidden script. This script then downloads a second program called PowerShell, which runs silently from the computer’s temporary folder, making it much harder for antivirus software to detect.
Once the script is active, the attack can follow one of two different paths: it either launches a .NET file or an AutoIt dropper. Depending on which one is used, different types of harmful programs are installed on the victim’s device. Although each step of the attack is simple, when combined, they make the entire process harder to spot and stop.
What is Agent Tesla?
One of the main threats delivered by this campaign is Agent Tesla. Agent Tesla is a type of malware known as a Remote Access Trojan (RAT). It allows hackers to secretly access and steal important information from an infected device. Once inside, it can gather:
1. Usernames and passwords
2. Email contacts and communication details
3. Financial data
4. Saved information from web browsers
5. Screenshots from the user’s computer
6. Information from email apps
7. Records of everything typed (keystrokes)
It can even read private email and chat messages, making it very dangerous for both individuals and businesses.
The same attack campaign was also seen using other malware like Remcos RAT and XLoader, but Agent Tesla was a major part of the operation because of its strong data theft abilities.
Be Careful With Unknown Emails
Since the attack begins with a simple email, it’s important to stay cautious. Avoid opening attachments you weren't expecting, especially if the email asks you to check a payment or invoice you do not recognize.
