The Sophos 2022 Threat Report analyzes the following key trends: Once they have the malware they need, RaaS affiliates and other ransomware operators can turn to Initial Access Brokers and malware delivery platforms to find and target potential victims. This is fueling the second big trend anticipated by Sophos. “Ransomware thrives because of its ability to adapt and innovate,” said Chester Wisniewski, principal research scientist at Sophos. “For instance, while RaaS offerings are not new, in previous years their main contribution was to bring ransomware within the reach of lower-skilled or less well-funded attackers. This has changed and, in 2021, RaaS developers are investing their time and energy in creating sophisticated code and determining how best to extract the largest payments from victims, insurance companies, and negotiators. They’re now offloading to others the tasks of finding victims, installing and executing the malware, and laundering the pilfered cryptocurrencies. This is distorting the cyberthreat landscape, and common threats, such as loaders, droppers, and Initial Access Brokers that were around and causing disruption well before the ascendancy of ransomware, are being sucked into the seemingly all-consuming ‘black hole’ that is ransomware. “It is no longer enough for organizations to assume they’re safe by simply monitoring security tools and ensuring they are detecting malicious code. Certain combinations of detections or even warnings are the modern equivalent of a burglar breaking a flower vase while climbing in through the back window. Defenders must investigate alerts, even ones which in the past may have been insignificant, as these common intrusions have blossomed into the foothold necessary to take control of entire networks.” Additional trends Sophos analyzed include:
After the ProxyLogon and ProxyShell vulnerabilities were discovered (and patched) in 2021, the speed at which they were seized upon by attackers was such that Sophos expects to see continued attempts to mass-abuse IT administration tools and exploitable internet facing services by both sophisticated attackers and run-of-the-mill cybercriminals.
Sophos also expects cybercriminals to increase their abuse of adversary simulation tools, such as Cobalt Strike Beacons, mimikatz and PowerSploit. Defenders should check every alert relating to abused legitimate tools or combination of tools, just as they would check a malicious detection, as it could indicate the presence of an intruder in the network.
In 2021, Sophos researchers detailed a number of new threats targeting Linux systems and expect to see a growing interest in Linux-based systems during 2022, both in the cloud and on web and virtual servers.
Mobile threats and social engineering scams, including Flubot and Joker, are expected to continue and diversify to target both individuals and organizations.
The application of artificial intelligence to cybersecurity will continue and accelerate, as powerful machine learning models prove their worth in threat detection and alert prioritization. At the same time, however, adversaries are expected to make increasing use of AI, progressing over the next few years from AI-enabled disinformation campaigns and spoof social media profiles to watering-hole attack web content, phishing emails and more as advanced deepfake video and voice synthesis technologies become available.
