TRENDING key tactics cybercriminals are using to attack businesses. Maya Horowitz, Threat Intelligence Group Manager at Check Point, said: “The first half of this year saw criminals continue the trend we observed at the end of 2017 and take full advantage of stealthy cryptomining malware to maximise their revenues. “We’ve also seen increasingly sophisticated attacks against cloud infrastructures and multi-platform environments emerging. These multi-vector, fast-moving, large-scale Gen V attacks are becoming more and more frequent and organisations need to adopt a multi-layered cybersecurity strategy that prevents these attacks from taking hold of their networks and data.” Top cryptominers during H1 2018 1.

Motivated by a clear interest to increase the percentage of computational resources leveraged and be even more profitable, cryptominers today target anything that could be perceived as being in their way. Cryptominers have also highly evolved recently to exploit high-profile vulnerabilities and to evade sandboxes and security products in order to expand their infection rates Top mobile malware during H1 2018 1. Triada (51%) – A modular backdoor for Android which grants superuser privileges to downloaded malware as it helps it to get embedded into system processes. Triada has also been seen spoofing URLs loaded in the browser 2. Lokibot (19%) – A mobile banking trojan which targets Android smartphones and turns into a ransomware upon an attempt of the victim trying to remove its admin privileges 3. Hidad (10%) – Android malware which repackages legitimate apps and then releases them to a third party store. It is able to gain access to key security details built into the OS, allowing an attacker to obtain sensitive user data Top banking malware during H2 2017 10. Ramnit 1.

Several cloud-based attacks, mainly those involving data exfiltration and information disclosure, derived from poor security practices, including credentials left available on public source code repositories or the use of weak passwords. Cryptominers are also targeting “ WITH ORGANISATIONS MOVING MORE OF THEIR IT ESTATES AND DATA TO CLOUD ENVIRONMENTS, CRIMINALS ARE TURNING TO THE CLOUD TO EXPLOIT ITS VAST COMPUTATIONAL POWER AND MULTIPLY THEIR PROFITS. www.intelligentcio.com
