Six-day, 14.7 Million RPS Web DDoS Attack Campaign Attributed to SN_BLACKMETA

Key Attack Insights:

  • Web DDoS attack campaign lasted six days and peaked at 14.7 Million RPS
  • Featured multiple attack waves amounting to a total of 100 hours of attack time
  • Sustained an average of 4.5 million RPS
  • Targeted a financial institution in the Middle East
  • Averaged a 0.12% ratio of legitimate to malicious web requests
  • Attributed by Radware to SN_BLACKMETA, a pro-Palestinian hacktivist with potential ties to Sudan that may operate from within Russia
  • Possibly leveraged the InfraShutdown premium DDoS-for-hire service
Stargazers Ghost Network
  • Check Point Research identified a network of GitHub accounts (Stargazers Ghost Network) that distribute malware or malicious links via phishing repositories. The network consists of multiple accounts that distribute malicious links and malware and perform other actions such as starring, forking, and subscribing to malicious repositories to make them appear legitimate.
  • This network is a highly sophisticated operation that acts as a Distribution as a Service (DaaS). It allows threat actors to share malicious links or malware for distribution through highly victim-oriented phishing repositories.
  • Check Point Research is tracking the threat group behind this service as Stargazer Goblin. The group provides, operates, and maintains the Stargazers Ghost Network and distributes malware and links via their GitHub Ghost accounts.
  • The network distributed all sorts of malware families, including Atlantida Stealer, Rhadamanthys, RisePro, Lumma Stealer, and RedLine.
  • Our latest calculations suggest that more than 3,000 active Ghost accounts are part of the network. Based on core GitHub Ghost accounts, we believe that the network began development or testing on a smaller scale for the first time around August 2022.
  • Check Point Research discovered an advertiser in Dark-Web forums that provides the exact GitHub operation. The first advertisement was published on July 8, 2023, from an account created the previous day.
  • Based on the monitored campaigns from mid-May to mid-June 2024, we estimate that Stargazer Goblin earned approximately $8,000. However, we believe that this amount is only a small fraction of what the actor made during that period. The total amount during the operations’ lifespan is estimated to be approximately $100,000.
  • Stargazers Ghost Network appears to be only one part of the grand picture, with other Ghost accounts operating on different platforms, constructing an even bigger Distribution as a Service universe.
DDoS Attacks in Spain

In the wake of Spanish Authorities arresting three individuals associated with NoName057(16), the group declared a "holy war" on Spain. The call to arms encourages all pro-Russian hacker groups to join under the hashtag #FuckGuardiaCivil. Over the past two days, NETSCOUT observed a significant increase in claimed attacks on Spanish websites, coinciding with the call to arms in retaliation for the arrests made. Despite the surge in hacktivist targeting and claims of victory, the daily DDoS attacks manifest as a normal day for Spanish network operators.

TuDoor

TuDoor is a new DNS attack, which could be exploited to carry out DNS cache poisoning, denial-of-service, and resource consuming.

DNS can be compared to a game of chess in that its rules are simple, yet the possibilities it presents are endless. While the fundamental rules of DNS are straightforward, DNS implementations can be extremely complex. In this study, we intend to explore the complexities and vulnerabilities in DNS response pre-processing by systematically analyzing DNS RFCs and DNS software implementations.
