Chinese Redfly Hacked National Power Grid & Maintained Access for 6 Months

Cybersecurity researchers at Symantec’s Threat Hunter Team recently discovered that the Redfly threat actor group used ShadowPad Trojan to breach an Asian national grid for 6 months.

Artificial intelligence-driven cyber threats grow as technology advances, significantly influencing and boosting threat actor sophistication.

Persistent espionage attacks by threat actors on critical national infrastructure (CNI) raise global concerns among governments and CNI entities.

In this security breach, the threat actors successfully stole the credentials and compromised computers.

The latest attack is part of the ongoing global CNI espionage wave, with the following countries on high alert after the Volt Typhoon’s U.S. infiltration:-

  • The U.S.
  • The UK
  • Australia
  • Canada
  • New Zealand

ShadowPad is initially a modular, short-lived underground RAT, now tied to espionage groups like APT41. Recent power grid attacks linked to Redfly, distinct from Blackfly and Grayfly.

Tools used

Here below, we have mentioned all the tools that the threat actors use in these attacks:-

Technical analysis

Initial intrusion on February 28, 2023, followed by ShadowPad execution on May 17, confirming attackers’ presence. A suspicious 1.bat file ran on May 16, leading to PackerLoader execution in the %TEMP% directory.

Next, all-user access is granted to dump_diskfs.sys driver, potentially for file system dumps and exfiltration. From the following Windows registry, the credentials were dumped:-

  • reg save HKLM\SYSTEM system.save
  • reg save HKLM\SAM sam.sav
  • reg save HKLM\SECURITY security.save

On May 19, attackers returned, running PackerLoader and 1.bat, then with the help of a sneaky “displayswitch.exe” file, Redfly launched their malicious payload. 

While besides this, they later used PowerShell to spy on the writable drives. Apart from this, the displayswitch.exe was triggered in %TEMP% on May 26 and swiftly dumped the registry credentials and erased the security logs.

Next, the attackers used ProcDump on May 29 and Oleview on May 31 for malicious activities and possibly leveraged the stolen credentials for lateral movement.

Over the past year, threat actors have actively targeted and attacked the CNI organizations. Even their attack frequency has also significantly increased, which is now a concerning factor.

Threat actors maintaining a long-term presence on grids pose the risk of disruptive attacks in nation-states during political tension.

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
