Brilliant Phishing Attack Targeting Critical Infrastructure and Manufacturing Industries

Nowadays attackers targeting users more innovatively through Emails and many other ways. This malware attack particularly targeting power sectors including Nuclear power stations.

Attackers used Malicious Word documents in this attack with a different behavior this time. This attack was identified by Talos intelligence.

There is no malicious code with attachment itself instead of it download file over SMB connection and steals user credentials silently, also it will download some other malicious payloads to infect victim’s computer.

Talos says “One objective of this most recent attacks appear to be to harvest credentials of users who work within critical infrastructure and manufacturing industries.”

Attack Flow

They came through various DOCX samples which were delivered as attachments in malicious spam emails.If the victim opens the attachment the document will try to pull down a template and there is a connection over port 80 and with port 445 they captured a handshake failure.

As per their initial analysis, malicious SMB server was used to harvest the victim’s credentials and the connection to external server established over SMB.

Later they confirmed with another related sample with another external server listening on Port 80 but No Templates served.

Brilliant Phishing Attack Targeting Critical Infrastructure

They research further with the entity relationship ID rId133 that found in word/_rels/settings.xml.rels and reached to GitHub page of a phishing tool named Phishery.

They found the same rID in the Phishery source, but Phishery doesn’t rely on SMB, instead, it handles connection over HTTPS.You can refer Talos for Technical analysis.

Talos said “At this time, there is no evidence to confirm any of the three possibilities. However, the attackers’ reliance on a successful SMB session stemming from outbound traffic over TCP 445 further confirms that organizations are still failing to properly block such egress traffic to public hosts.”

Common Defence’s to stay safe

  • Don’t open the attachments that you are not expecting.
  • Patch or Update your software.
  • Use a reputable security suite.
  • Disconnect Internet connection immediately.

Low Rate DDoS Attack

9 of 10 sites on the AppTrana network have faced a DDoS attack in the last 30 days.
Some DDoS attacks could readily be blocked by rate-limiting, IP reputation checks and other basic mitigation methods.
More than 50% of the DDoS attacks are employing botnets to send slow DDoS attacks where millions of IPs are being employed to send one or two requests per minute..
Key takeaways include:

  • The mechanics of a low-DDoS attack
  • Fundamentals of behavioural AI and rate-limiting
  • Surgical mitigation actions to minimize false positives
  • Role of managed services in DDoS monitoring
