Investigation reveals large botnet hiding behind Fast Flux technique

Fast Flux, a DNS technique first introduced in 2006 and widely associated with the Storm Worm malware variants, can be used by botnets to hide various types of malicious activities – including phishing, web proxying, malware delivery, and malware communication. The technique allows the botnet to “hide” behind an ever-changing network of compromised hosts, ultimately acting as proxies and making detection incredibly difficult. High-level architecture overview of the Fast Flux network ?and associated threat landscape … More ?

Week in review: Cyber threat hunting, Android DDoS botnet, drone bug bounty

Here’s an overview of some of last week’s most interesting news, podcasts and articles: New, custom ransomware delivered to orgs via extremely targeted emails Ransomware campaigns are usually wide-flung affairs: the attackers send out as many malicious emails as possible and hope to hit a substantial number of targets. But more targeted campaigns are also becoming a trend. Getting a start on cyber threat hunting We live in a world where the adversaries will persist … More ?

Whitepaper: Understanding pulse wave DDoS attacks

Pulse wave DDoS is a new attack tactic, designed to double the botnet’s output and exploit soft spots in “appliance first cloud second” hybrid mitigation solutions. Comprised of a series of short-lived bursts occurring in clockwork-like succession, pulse wave assaults accounted for some of the most ferocious DDoS attacks we ever mitigated. Reading this whitepaper will help you: Understand the nature of pulse wave DDoS attacks See how they are used to pin down multiple … More ?

An internet-connected fish tank let hackers into a casino’s network

A high-tech, internet-connected fish tank in a North American casino has been used to exfiltrate data from the company’s network. Smart drawing pads used in an architectural firm were part of a botnet used to mount DDoS attacks against websites around the world owned by entertainment companies, design companies, and government bodies. These are just some of the discoveries made by UK-based cyber defense Darktrace, but serve as perfect examples of how lax security when … More ?

Surprisingly stealthy botnet has been targeting users for years

ESET researchers have unearthed a botnet of some 500,000 infected machines engaged mostly in ad-related fraud by using malicious Chrome extensions, but also Facebook fraud and brute-forcing Joomla and WordPress websites. In addition to this, the compromised machines are also equipped with a fully featured backdoor, which allows the operators to spy on all the victims, and to download additional malware on the computers. A long-standing operation There are many unusual things about the so-called … More ?
