Fastrack Compliance: The Path to ZERO-Vulnerability

Compounding the problem are zero-day vulnerabilities like the MOVEit SQLi, Zimbra XSS, and 300+ such vulnerabilities that get discovered each month. Delays in fixing these vulnerabilities lead to compliance issues, these delay can be minimized with a unique feature on AppTrana that helps you to get “Zero vulnerability report” within 72 hours.

AgentTesla Malware Attacking Windows

AgentTesla is a .NET-written Windows malware that steals sensitive data and emerged for the first time in 2014. It faced legal issues once it was sold widely, leading to its shutdown in March 2019. 

It later reemerged as OriginLogger, which shares the same code base and poses a persistent threat as a licensed-based Malware as a Service (MaaS) on the clear web with websites like-

  • agenttesla[.]com
  • originpro[.]me

Researchers found that one of the sites sells short-term licenses (up to six months) for AgentTesla’s instance “OriginLogger” with several customizations. 

AgentTesla is a prevalent malware that was rebranded and updated in November. It spreads via phishing emails with loaders like:-

  • GuLoader
  • PureCrypter

After infecting it harvests the following data:-

  • Credentials
  • Keystrokes
  • Clipboard data
  • Screenshots 

Not only that even, it also uses various protocols like:-

  • SMTP
  • FTP
  • HTTP

Over 1500 recent AgentTesla configurations were found, and 75% used email for exfiltration. However, since December 2022, no HTTP exfiltration has been observed.

The data gathered by the malware are mainly from:-

  • Browsers
  • VPN clients
  • Mail clients
  • FTP clients
  • VNC clients
  • Microsoft Applications
  • Social media apps

Pricing plans

In total, there are three plans, and here below, we have mentioned those three plans:-

  • 1-month plan will cost $50
  • 3-month plan will cost $75
  • 4-month plan will cost $90

Researchers accessed 3 months of victim data from 210 malware campaigns, compromising 5300 computers between Oct-Dec 2023. 

Around 2000 IP addresses were geographically mapped, which shows that the U.S. was the most targeted country, followed by

  • China
  • Germany

Common country top-level domains suggested European ties. Exploited data is used for direct exploitation and profit-driven schemes like ransomware and business email compromise attacks.

To counter the evolving threats, researchers urged to integrate the:-

  • Multi-layered defense mechanism
  • Proactive detection
  • Employee awareness
  • Robust cybersecurity strategy
