Thousands of WordPress Blogs Compromised for DDoS Attacks

September 25, 2013

A massive cyber attack campaign is currently targeting numerous WordPress websites across the internet. In April 2012, we reported on a widespread brute force attack against millions of WordPress sites, resulting in the compromise of approximately 90,000 servers to form a large botnet of WordPress hosts. Recent DDoS attack logs received from reader Steven Veldkamp at ‘The Hacker News’ reveal that victims’ websites are experiencing heavy DDoS attacks, stemming from various compromised WordPress sites.

Utilizing brute force techniques on WordPress administrative portals, hackers are exploiting poorly secured hosts using commonly known username and password combinations. An analysis of DDoS attack logs from September 23, 2013, indicates a storm of malicious activity over just 26 seconds…

Cybercriminals Leverage X’s Grok AI to Circumvent Ad Safeguards and Distribute Malware to Millions

Sep 04, 2025
Artificial Intelligence / Malware

Cybersecurity experts have identified a new tactic employed by cybercriminals to circumvent the malvertising protections of social media platform X, utilizing its AI assistant Grok to disseminate harmful links. This method, dubbed “Grokking,” was discussed in a series of posts by Nati Tal, head of Guardio Labs.

The technique aims to exploit the limitations set by X on Promoted Ads, which typically permit only text, images, or videos for advertising. By leveraging video card-promoted posts featuring adult content as bait, malvertisers cleverly conceal malicious links in the “From:” metadata field located below the video player—an area that goes unchecked by the platform’s security measures.

16-Year-Old Arrested for Involvement in History’s Largest Cyber Attack

Sept 27, 2013

A 16-year-old has been detained for allegedly participating in the largest DDoS attack ever recorded, targeting the Dutch anti-spam organization Spamhaus. The arrest, made by British police in April, came to light recently. Authorities stormed his home in south-west London after discovering substantial funds in his bank account. Upon investigation, he was found with various computer systems logged into virtual forums. The March 20 attack on Spamhaus was described as a monumental event in cybercrime, unleashing a torrent of traffic measured at 300 billion bits per second (300Gbps). DDoS attacks occur when hackers mobilize a network of infected computers to overwhelm a server, leading to shutdowns.

GhostRedirector Compromises 65 Windows Servers Through Rungan Backdoor and Gamshen IIS Module

Sep 04, 2025
Data Breach / Malware

Cybersecurity experts have uncovered a new threat cluster known as GhostRedirector, which has infiltrated at least 65 Windows servers predominantly located in Brazil, Thailand, and Vietnam. According to Slovak cybersecurity firm ESET, the attacks have resulted in the installation of a passive C++ backdoor named Rungan, alongside a native Internet Information Services (IIS) module referred to as Gamshen. The threat actor is thought to have been active since at least August 2024.

“While Rungan can execute commands on an infected server, Gamshen is designed to facilitate SEO fraud as-a-service, manipulating search engine results to enhance the page ranking of a specified target website,” stated ESET researcher Fernando Tavella in a report shared with The Hacker News. “Notably, Gamshen only alters responses when requests come from Googlebot, ensuring that regular visitors are not impacted.”

Microsoft Alerts Users to Cross-Account Takeover Vulnerability in Azure Container Instances

On September 10, 2021, Microsoft announced that it had fixed a security flaw in its Azure Container Instances (ACI) service that could be exploited by malicious actors to gain unauthorized access to information from other customers. Researchers referred to this vulnerability as the “first cross-account container takeover in the public cloud.” An attacker could use this weakness to execute harmful commands on other users’ containers, potentially stealing customer secrets and deployed images. Microsoft did not provide further details about the flaw but advised affected customers to “revoke any privileged credentials that were deployed to the platform before August 31, 2021.” Azure Container Instances enables users to run Docker containers directly in a serverless cloud environment without the need for virtual machines, clusters, or orchestration tools. Palo Alto Networks’ Unit 42 threat intelligence team identified the vulnerability…

The Significance of Logs and Log Management in IT Security

In today’s digital landscape, IT security is paramount for organizations of all sizes. Effective security measures begin with vigilant monitoring of your network to identify vulnerabilities that could expose sensitive information to threats. This often includes employing firewalls as the first line of defense, alongside vulnerability management, intrusion detection and prevention systems, and careful configuration of network settings.

The importance of these measures cannot be overstated:

  • Routers may be easily compromised without proper configuration and restrictions.
  • An improperly configured firewall can leave open ports, enabling hackers to infiltrate the network.
  • Threats like rogue access points, botnet malware, and social engineering can transform your wireless network into a gateway for unauthorized access.

Why Are Logs Essential?
