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 ?

Tech firms band together to take down Android DDoS botnet

An ad-hoc alliance of tech firms has managed to seriously cripple an Android-based botnet that was being actively used to DDoS multiple content providers. The botnet, dubbed WireX by the researchers, consisted of Android devices with malicious apps installed. In fact, in the wake of the discovery, Google has pulled some 300 such apps from Google Play, began removing them remotely from affected users’ devices, and blocked them from being installed. The malicious apps The … More ?

Malicious content delivered over SSL/TLS has more than doubled in six months

Threats using SSL encryption are on the rise. An average of 60 percent of the transactions in the Zscaler cloud have been delivered over SSL/TLS. Researchers also found that the Zscaler cloud saw an average of 8.4 million SSL/TLS-based security blocks per day this year. “Hackers are increasingly using SSL to conceal device infections, shroud data exfiltration and hide botnet command and control communications. In fact, our study found that the amount of phishing attempts … 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 ?

There’s now a WannaCry decryptor tool for most Windows versions

As the criminals behind the WannaCry ransomware are trying to make it work again, security researchers have created tools for decrypting files encrypted by it. DDoS attacks against the killswitch domains Since researcher Marcus Hutchins (aka MalwareTech) registered a (previously non-existent) killswitch domain for the malware and stopped its onslaught, the domain has been under attack by Mirai-powered botnets. Today’s Sinkhole DDoS Attack pic.twitter.com/wxT2YUrdOF — MalwareTech (@MalwareTechBlog) May 18, 2017 That particular domain has been … More ?

Hajime IoT worm infects devices to head off Mirai

Mirai is the name of the worm that has taken control of many IoT devices around the world and used them to mount DDoS attacks, the most high-profile of which was directed against US-based DNS provider Dyn and resulted in many websites and online services being inaccessible for hours on end. Its source code was leaked by the author, which lead to the creation of more botnets, and an increased fear that we’ll soon witness … More ?

IoT devices under attack: Amnesia hijacks, BrickerBot destroys

Every hour of every day, computer systems and IoT devices are under attack by bots trying to recruit them into growing botnets. Security researchers have recently highlighted two of these threats coming after Linux- and BusyBox-based systems and devices. Amnesia A year after security researcher Rotem Kerner discovered a remote code execution vulnerability that affected digital video recorders (DVRs) manufactured by Chinese company TVT Digital and sold by more than 70 different vendors around the … More ?
