Cyber criminals are exploiting android apps and misconfigured cloud platforms for attacks

Sophos have reported on the current attack trends in which attackers are raising the stakes in ransomware by increasing stealth in malicious Android apps, exploiting misconfiguration in the cloud and abusing machine learning.

During the launch of Sophos 2020 Threat Report that provides insights into the rapidly evolving cyber threat landscape, produced by SoophosLabs researchers, the security experts explored changes in the threat landscape over the past 12 months, uncovering trends likely to impact cybersecurity in 2020.

“The threat landscape continues to evolve – and the speed and extent of that evolution is both accelerating and unpredictable,” said John Shier – Senior Security Advisor at Sophos.

The 2020 Threat Report looks at how current trends might impact the world over the coming year and further highlights how adversaries are becoming ever stealthier, better at exploiting mistakes, hiding their activities and evading detection technologies and more, in the cloud, through mobile apps and inside networks. The only certainty we have is what is happening right now.

The report is not so much a map as a series of signposts to help defenders better understand what they could face in the months ahead, and how to prepare.

The SophosLabs 2020 Threat Report, which is also summarized in a SophosLabs Uncut article, focuses on six areas where researchers noted particular developments during this past year. Among those expected to have significant impact on the cyberthreat landscape into 2020 and beyond are the following:

Ransomware attackers continue to raise the stakes with automated active attacks that turn organizations’ trusted management tools against them, evade security controls and disable back ups in order to cause maximum impact in the shortest possible time.

Unwanted apps are edging closer to malware. In a year that brought the subscription-abusing Android Fleeceware apps and ever more stealthy and aggressive adware, the Threat Report highlights how these and other potentially unwanted apps (PUA), like browser plug-ins, are becoming brokers for delivering and executing malware and fileless attacks.

The greatest vulnerability for cloud computing is misconfiguration by operators. As cloud systems become more complex and more flexible, operator error is a growing risk. Combined with a general lack of visibility, this makes cloud computing environments a ready made target for cyberattackers.

Machine learning designed to defeat malware finds itself under attack. 2019 was the year when the potential of attacks against machine learning security systems were highlighted. Research showed how machine learning detection models could possibly be tricked, and how machine learning could be applied to offensive activity to generate highly convincing fake content for social engineering. At the same time, defenders are applying machine learning to language as a way to detect malicious emails and URLs. This advanced game of cat and mouse is expected to become more prevalent in the future.

Other areas covered in the 2020 Threat Report include the danger of failing to spot cybercriminal reconnaissance hidden in the wider noise of internet scanning, the continuing attack surface of the Remote Desktop Protocol (RDP), and the further advancement of automated active attacks (AAA).
