On the heels of Rio Olymips 2016, which has beguiled from Brazil brings frenzy question in terms of Security. Fortinet announces the findings of its FortiGuard Labs cyber threat landscape global report citing on the increased threat activity in Brazil and explains why it deserves special attention during the Rio Olympics.
The volume of malicious and phishing artifacts (i.e. domain names and URLs) in Brazil is on the rise. In June, Brazil’s percentage increase was higher in three of four categories in Fortinet’s report when compared with the global percentage increase. The highest percentage growth was in the malicious URL category at 83% compared to 16% for the rest of the world.
As the 2016 Rio Olympics approaches, the history of these increased attacks will undoubtedly continue and FortiGuard Labs is already seeing indicators of repeat techniques such as domain lookalikes for payment fraud and malicious websites or URLs targeting event and government officials.
Fortinet FortiGuard Labs research is seeing a return of old threats and attack vectors, and the continued persistence of classic attacks, such as Conficker and ransomware, through updated variants. Fortinet’s telemetry data and research indicates that the two most common delivery methods are phishing emails and malicious websites.
- Advanced Threat Technique – “Behavior Blending”: Over the past three months a sophisticated method to help attackers persist inside systems they have breached is on the rise. Behavior blending is a technique used by criminals that allows them to blend in on a compromised network. For example, on a corporate network, the attacker may take on the behavior of an employee to avoid detection. Given this evasion technique has a lot of potential for thwarting detection, Fortinet expects to see more of it as it is refined and new tools are developed to better mimic the behavior of a credentialed target.
- Phishing: The volume of global phishing activity remains high with a 76% increase from April to June based on FortiGuard Labs’ phishing domains and URLs threat data. The percentage growth from May to June was 11%. Additional email phishing takeaways include increased activity from Tokelau with the top four country code domains in Q2 2016 being Brazil, Columbia, Russia and India. Additionally, domain lookalikes are still very active (e.g. nefflix vs netflix). Lastly, FortiGuard also observed a number of large financial institutions’ names included as part of the phishing domains and URLs.
- Advanced Malware: The JS/Nemucod family has been the dominant malware family globally in the last three months. This family is currently the most active ransomware downloader, with overall ransomware attacks significantly on the rise.
- Data Exfiltration – Botnet Indicators: FortiGuard’s threat telemetry shows botnet activity and chatter on the rise, with ransomware botnet activity from Locky and Cryptowall as the notable names in the top 10.
Cyberattacks during the Olympic games are not new as Fortinet FortiGuard Labs research claims to have found a spike of attacks focused on the Olympics beginning as far back as the 2004 Summer Olympics in Greece.
“The expanding attack surface enabled by technology innovation, new IoT devices, regulatory pressures, and a global shortage of cybersecurity talent continue to drive cyber threats. All of these elements combined with global political events add more complexity to the situation and complexity is the enemy of security. Simply deploying security point solutions end-to-end is not enough. Organizations need to adopt a Security Fabric that will enable direct communication between solutions for a unified and rapid response to advanced threats,” said Rajesh Maurya, Regional Director, India & SAARC, Fortinet.
