On January 15th, France’s chief information systems defense official, Adm. Arnaud Coustilliere, announced a sharp rise in online attacks against French web sites:
“Calling it an unprecedented surge, Adm. Arnaud Coustilliere, head of cyberdefense for the French military, said about 19,000 French websites had faced cyberattacks in recent days, …” .
As we’ve done in the recent past for North Korea , Hong-Kong , and Israel , we can leverage Arbor’s ATLAS initiative to observe how real world conflict […]
It was reported earlier today that North Korea was having Internet connectivity issues.
Given recent events involving Sony Pictures Entertainment (SPE), these reports are of particular interest. The first question when you see this type of report is whether it’s purely a connectivity issue or whether an attack is behind it. While visibility into North Korean Internet is quite difficult, we are able to see quite a few attacks over the last few days.
1.) All targets are in this netblock:
inetnum: 126.96.36.199 […]
In early August, we examined data demonstrating a striking correlation between real-world and online conflict , which ASERT tracks on a continual basis [2-7]. Recent political unrest provides another situation in which strong correlative indicators emerge when conducting time-series analysis of DDoS attack data.
The latest round of pro-democracy protests in Hong Kong began on September 22nd when “. . . Students from 25 schools and universities go ahead with a week-long boycott to protest Beijing’s decision to proceed with indirect […]
It’s been far too long since the last MindshaRE post, so I decided to share a technique I’ve been playing around with to pull C2 and other configuration information out of malware that does not store all of its configuration information in a set structure or in the resource section (for a nice set of publicly available decoders check out KevTheHermit’s RATDecoders repository on GitHub). Being able to statically extract this information becomes important in the event that […]
Yesterday, the Communications Security, Reliability and Interoperability Council (CSRIC), a federal advisory committee to the Federal Communications Commission (FCC), submitted its final report on Remediation of Server-based DDoS Attacks.
The CSRIC’s Working Group 5 was tasked with developing recommendations for communications providers to enable them to mitigate the impact of high volume DDoS attacks launched from large data center and hosting environments.
The final report includes a comprehensive look at the DDoS threat landscape, covering everything from the massive size […]

NewPosThings is a point of sale (PoS) malware family that ASERT has been tracking for a few weeks. It operates similarly to other PoS malware by memory scraping processes looking for credit card track data and then exfiltrating the spoils to a command and control (C2) server. Based on compilation times, it has been in active development since at least October 20, 2013—with the latest timestamp being August 12, 2014. Since we haven’t come across […]
Last week in Chicago, at the annual SIGCOMM flagship research conference on networking, Arbor collaborators presented some exciting developments in the ongoing story of IPv6 roll out. This joint work (full paper here) between Arbor Networks, the University of Michigan, the International Computer Science Institute, Verisign Labs, and the University of Illinois highlighted how both the pace and nature of IPv6 adoption has made a pretty dramatic shift in just the last couple of years. This study is a thorough, well-researched, effective analysis and […]

It has been a few weeks since news broke of the Zeus Gameover variant known as newGOZ. As has been reported, the major change in this version is the removal of the P2P command and control (C2) component in favor of a new domain generation algorithm (DGA).
The DGA uses the current date and a randomly selected starting seed to create a domain name. If the domain doesn’t pan out, the seed is incremented and the […]
Since its inception, the ASERT team has been looking into politically motivated DDoS events  and continues to do so as the relationship between geopolitics and the threat landscape evolves . In 2013, ASERT published three situational threat briefs related to unrest in Syria  and Thailand  and threat activity associated with the G20 summit . Recently, other security research teams, security vendors and news agencies have posited connections between “cyber” and geopolitical conflicts in Iraq , Iran , […]
As the infosec community waits for the researchers involved to present their Zeus Gameover take down spoils at the next big conference; ASERT wanted to profile a threat actor that uses both Citadel, “a particularly sophisticated and destructive botnet”, and Gameover, “one of the most sophisticated computer viruses in operation today”, to steal banking credentials.
When a threat actor decides that they would like to start a Citadel campaign they: buy the builder software, build the malware, distribute […]
