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 ?

Here we go again: DDoS attacks on the rise!

Newly released data shows that DDoS and web application attacks are on the rise once again, according to Akamai’s Second Quarter, 2017 State of the Internet / Security Report. Contributing to this rise was the PBot DDoS malware which re-emerged as the foundation for the strongest DDoS attacks seen by Akamai this quarter. In the case of PBot, malicious actors used decades-old PHP code to generate the largest DDoS attack observed by Akamai in 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 ?

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 ?

Stealthy DDoS attacks distract from more destructive security threats

The greatest DDoS risk for organisations is the barrage of short, low volume attacks which mask more serious network intrusions. Despite several headline-dominating, high-volume DDoS attacks over the past year, the vast majority (98%) of the DDoS attack attempts against Corero customers during Q1 2017 were less than 10 Gbps per second in volume. In addition, almost three quarters (71%) of the attacks mitigated by Corero lasted 10 minutes or less. Due to their small … More ?

8 RCE, DoS holes in Microsoft Malware Protection Engine plugged

After the discovery and the fixing of a “crazy bad” remote code execution flaw in the Microsoft Malware Protection Engine earlier this month, now comes another MMPE security update that plugs eight flaws that could lead to either remote code execution or to denial of service. Given that the Microsoft Malware Protection Engine powers a number of Microsoft antimalware software, DoS vulnerabilities should be considered serious, since a successfully exploited vulnerability could prevent the MMPE … 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.

Bondnet botnet goes after vulnerable Windows servers

A botnet consisting of some 2,000 compromised servers has been mining cryptocurrency for its master for several months now, “earning” him around $1,000 per day. GuardiCore researchers first spotted it in December 2016, and have been mapping it out and following its evolution since then. The’ve dubbed it Bondnet, after the handle its herder uses online (“Bond007.01”). Compromised Windows servers serve different functions Bondnet’s main reason of being is the mining of cryptocurrencies: primarily Monero, … More ?

Malware Hunter: Find C&C servers for botnets

Recorded Future and Shodan released Malware Hunter, a specialized crawler for security researchers that explores the Internet to find computers acting as remote access trojan (RAT) command and control centers. What Malware Hunter does Malware Hunter unearths computers hosting RAT controller software that remotely controls malware-infected computers and instructs them to execute malicious activities such as recording audio, video, and keystrokes on a victim’s machine. Using command and control servers, attackers can launch widescale attacks … More ?
