Emotet adds a further layer of camouflage 2019-03-27 UTC
Most professionals within enterprise security have come across ‘Emotet'. As its history illustrates, the criminals behind Emotet malware are cunning and quick to maximize its ‘potential.' From a basic banking Trojan to a threat distribution service, it is constantly being re-invented. This ‘constant malware improvement’ isn’t showing any sign of abating. Recently the Spamhaus Malware Labs team have identified further unsettling changes in Emotet.... (>)

Exploits Block List - Two Botnets Contribute to 50% Increase in Listings 2018-10-26 UTC
If you’ve been monitoring the Exploits Block List (XBL) recently you will have noticed a significant increase in the number of listings. The past few weeks have seen a lift from approximately 10 million to 15 million listings. The question is why? Our botnet specialist explains…... (>)

Fighting abuse at the edge 2018-04-09 UTC
Take a look at org charts, international standards, conferences and forums…you will observe there are two tribes; one for the ‘network’ the other for ‘applications’. It’s a distinction that’s embedded in Information Technology with the Network Layer ‘below’ all applications with a dedicated team dealing with connectivity, routers, upstreams and peering, all quite independently from the nature of the data that is flowing. Another team deals with ‘applications’; email, web services, etc., that do their job without having to consider the underlying aspects related to networking.... (>)

Spamhaus Botnet Threat Report 2017 2018-01-08 UTC
Now that 2017 is behind us, as we do each year, the Spamhaus Project would like to give some numbers and thoughts on the botnet threats we encountered. In 2017, Spamhaus Malware Labs identified and issued Spamhaus Block List (SBL) listings for more than 9,500 botnet Command & Control servers on 1,122 different networks. A botnet controller, commonly abbreviated as "C&C", is being used by fraudsters to both control malware infected machines and to extract personal and valuable data from malware infected victims. Botnet controllers therefore play a core role in operations conducted by cybercriminals who are using infected machines to send out spam, ransomware, launch DDoS attacks, commit ebanking fraud, click-fraud or to mine cryptocurrencies such as Bitcoin. An infected machine can be a desktop computer, mobile device (like a smartphone) but also an IoT device ("Internet Of Things") device such as webcam or network attached storage (NAS) that is connected to the internet....

Botnet Controllers in the Cloud 2017-04-25 UTC
Cloud computing is popular these days. Millions of users consume computing power out of the cloud every day. Cloud computing comes with several advantages over traditional server hosting, such as scalability and quick deployment of new resources. As of January 2017, several large botnet operators appear to have discovered the benefits of cloud computing as well, and have started to... (>)

Spamhaus Botnet Summary 2016 2017-01-17 UTC
2016 was a busy year for existing and emerging cyber threats. In the past year, Spamhaus researchers issued listings for over 7,000 botnet Command & Control ("C&C") servers on more than 1,100 different networks. These C&C servers enabled and controlled online crime such as credential theft, e-banking fraud, spam and DDoS attacks. They were also used for the retrieval of stolen data. 2016 will also go down in history as the first year that security issues related to the 'Internet-of-Things' not only became mainstream, but turned into a serious enabler of ever larger attacks and a source of many future problems....

Spamhaus Botnet Summary 2014 2014-12-31 UTC
As 2014 ends, Spamhaus reviews the botnet threats that it detected in the past year, and provides facts and useful suggestions for ISPs and web hosts on the front lines of the battle against cybercrime. To nobody's surprise, botnet activity appears to be increasing. The majority of detected botnets are targeted at obtaining and exploiting banking and financial information. Botnet controllers (C&Cs) are hosted disproportionately on ISPs with understaffed abuse departments, inadequate abuse policies, or inefficient abuse detection and shutdown processes. Botnet C&C domains are registered disproportionately with registrars in locations that have lax laws or inadequate enforcement against cybercrime.... (>)
