The political tension after the Catalonia referendum on October 1, 2017, has influenced the virtual arena as well, resulting in cyber-attacks against Spanish websites carried out by hacktivists leaking information about high profile targets and claiming responsibility for shutting down websites. These threat actors use various anti-Spain hashtags that indicate the different cyber campaigns: #OpEspana, #OpCatalonia, #OpCatalonya and #OpSaveCatalonia.

Hacktivists recently launched the fifth phase of the #OpIcarus cyber campaign (also dubbed #OpSacred) against the financial sector around the world. This campaign was first launched in February 2016, and as in previous phases, the official target list contains mainly websites of central banks around the world. In addition, the initiators share links to download known DDoS tools, such as Continue reading “#OpIcarus Cyber Campaign – Round 5”
The number of participants in the event pages of the #OpIsrael campaign, as of the first week of April 2017, is approximately 600 Facebook users – a very low number of supporters compared to the same period in previous campaigns. In general, the response on social networks to the #OpIsrael campaign over the years since 2013 is constantly declining. Continue reading “Updates about the Upcoming #OpIsrael Campaign”
During the past week, we detected indications for initial preparations for the upcoming #OpIsrael campaign scheduled for April 7, 2017. SenseCy identified several event pages on Facebook that were opened explicitly to organize cyber-attacks. The number of participants in all the event pages that we found is relatively low (approximately 160 Facebook users). Continue reading “Initial Preparations for #OpIsrael 2017”

While monitoring closed platforms that propagate an Islamic State agenda, we detected an initial interest in hacking lessons, focusing on spam and phishing methods. Many discussions in the technical sections of closed platforms affiliated with the Islamic State deal with the implementation of Continue reading “Jihadi Cybercrime (Increasing Interest in Spam and Phishing Methods on Closed Islamic State Platforms)”
The Mirai IoT Botnet has made a lot of headlines in recent weeks. While the botnet itself was analyzed and discussed by a number of security researchers and companies, none addressed the threat actor behind the recent attacks and the leak of Mirai source code. Such an analysis can provide useful insights into Continue reading “Anna-senpai – Analysis of the Threat Actor behind the Leak of Mirai”
In early September 2016, a new advertisement appeared on various Darknet platforms, promoting a new hidden service. The service, dubbed Open Hacking Lab (OHL), offers three categories of products: hacking tools and resources, hacked credentials and services. While numerous hidden services on the Darknet sell hacked credentials, this is the first time we have observed the sale of administrator credentials for Office 365 accounts.
Microsoft Office 365 is a software package that includes cloud services, sold to corporates and private customers. The organizational package includes email, storage, social network, SharePoint and other services provided via cloud. Acquiring administrator’s access to organization that use Office 365 will provide a potential attacker with access to sensitive organizational information and may even lead to the threat actor gaining full control over the organization network.
Currently, 12 accounts are being offered for sale, with prices ranging from $15 for a logistics company account to $100 for a law firm. For each company, the seller provides a short description of the company, its country of origin, and which data the buyer will gain access to. Eight of these companies are based in the U.S., two in Europe and two in Canada.
The operator of the hidden service is a well-known actor in several communities on the Darknet; he is considered credible and he possesses high technical skills. The hidden service owner also runs a Twitter account dedicated to the service, where he updates about the platform and its products.
Hacktivists are threatening to launch #OpClosedMedia, a month-long cyber campaign against websites and platforms of “mainstream media,” on September 22, 2016, for failing to inform the public about the real news.
The campaign’s official target list includes the websites of the BBC, The Daily Mail, The Independent, Reuters, Channel One (Russia) and others.
Thus far, participants have claimed responsibility for hacking several websites related to the media sector from around the world, but they also claimed to have hacked other websites with a loose connection to this sector.
This is not the first time that the media sector has been targeted by hacktivists. In June 2016, the Ghost Squad Hackers group launched the #OpSilence campaign against prominent news agencies, such as Fox News and CNN, protesting against what they called the “silence and lies” regarding the Palestinian situation. However, it seems that the Ghost Squad Hackers are not involved in this campaign.
In conclusion, popular news platforms and the media sector in general are targeted by hacktivists who wish to shut them down. Only time will tell if they will succeed or not.
During May 2016, we witnessed the second phase of the #OpIcarus cyber campaign against banks around the world, launched by the Anonymous collective in February 2016. The participants carried out DDoS attacks against bank websites in various countries on a daily basis. Several cyber-attacks succeeded in shutting down the websites of central banks in Greece, Cyprus and other countries.
The initiators created two Facebook event pages and opened an IRC channel to coordinate their cyber-attacks. Approximately 2,000 participants joined the #OpIcarus event pages, but many more hacktivists expressed their support of this campaign via their social media accounts. With regard to the dedicated IRC channel, it appears not to have been as active as the campaign platforms in Facebook and Twitter.
Attacks and Tools
According to news reports, #OpIcarus participants shut down bank websites around the world on a daily basis. We cannot confirm that all of the mentioned banks websites were actually offline, due to the participant DDoS attacks, but we wish to point out several incidents that caught our attention.
A member of the Ghost Squad Hackers group dubbed s1ege took responsibly for shutting down the email server of the Bank of England. The bank did respond to this attack, but according to news reports, the bank’s mail server was offline on May 13, 2016.
In addition, according to a single news report shared on various Facebook accounts, Chase Bank ATMs stopped working on May 14, 2016, as a result of the Anonymous collective cyber activity. The Twitter account of Chase Bank’s technical support tweeted that their ATMs did not accept any deposits on this day, but they did not mention what had caused the problem. Meanwhile, the Ghost Squad Hackers group tweeted that the incident was part of the #OpIcarus campaign.
Additionally, s1ege claimed on May 18, 2016, that they had shut down a website related to the NYSE. The NYSE Twitter account tweeted that they had experienced a technical issue in one of their trading units. They did not mention what had caused the problem. Therefore, it is unclear if there is any connection to the Ghost Squad Hackers group, aside from the latter’s claim of responsibility.
With regard to the attack tools, the participants used a variety of DDoS, some of which were simple online tools with no sophisticated DDoS abilities. However, there were indications that they used DDoS-as-a-Service (DaaS) platforms, such as Booters/Stressers that require payment and registration. In addition, the New World Hackers (NWH) team that took responsibility for shutting down the HSBC Bank website on January 29, 2016, supported the #OpIcarus campaign.
This campaign gained high popularity among hacktivists from all over the world who were motivated to DDoS bank websites protesting corruption and other issues. It is possible that the initiators will decide to engage an additional phase of this campaign, since one of them claimed in an interview that “Operation Icarus will continue as long as there are corrupt and greedy banks out there.”
