Andromeda botnet dismantled in international cyber operation

On 29 November 2017, the Federal Bureau of Investigation (FBI), in close cooperation with the Luneburg Central Criminal Investigation Inspectorate in Germany, Europol’s European Cybercrime Centre (EC3), the Joint Cybercrime Action Task Force (J-CAT), Eurojust and private-sector partners, dismantled one of the longest running malware families in existence called Andromeda (also known as Gamarue). According to Microsoft, Andromeda’s main goal was to distribute other malware families. Andromeda was associated with 80 malware families and, in … More ?

Criminals leverage unsecured IoT devices, DDoS attacks surge

Organizations experienced an average of 237 DDoS attack attempts per month during Q3 2017 – equivalent to 8 DDoS attack attempts every day – as hackers strive to take their organisations offline or steal sensitive data, according to Corero Network Security. The data, which is based on DDoS attack attempts against Corero customers, represents a 35% increase in monthly attack attempts compared to the previous quarter (Q2 2017), and a 91% increase in monthly attack … More ?

Infosec expert viewpoint: DDoS attacks

DDoS attacks have become more extensive and are testing the limits of existing DDoS mitigation tools and practices, as well as affecting online businesses globally. Organizations are experiencing an increase in the magnitude of DDoS attacks, with the average size of attacks over 50 Gbps quadrupling in just two years. What presents a particular risk for organizations is the barrage of short, low volume attacks that mask more serious network intrusions. Frost & Sullivan found … More ?

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 ?

Large DDoS attacks over 50 Gbps have quadrupled between 2015 and 2017

Organizations are experiencing an increase in the magnitude of DDoS attacks, with the average size of attacks over 50 Gbps quadrupling in just two years, according to A10 Networks. Growth of DDoS attacks The study also found the gargantuan 1 Tbps attacks that started last year with the Mirai botnet have begun to leave their mark, with 42% of organizations reporting an average size of DDoS attacks greater than 50 Gbps, a significant increase from … 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 ?

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 ?

Attack rates are increasing across the board

Finance and technology are the sectors most resilient to cyber intrusions, new research from Vectra Networks has found. The company released the results of its Post-Intrusion Report, based on data from a sample set of nearly 200 of its enterprise customers. They looked at the prevalence of strategic phases of the attack lifecycle: command-and-control (C&C), reconnaissance, lateral movement, botnet, and exfiltration attacker behaviours across thirteen industries. Over 90 days (January-March 2017), the company monitored 2,145,708 … 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 ?
