Five Cyber Security Predictions for 2023



As 2022 draws to a close, we reflect on a cyber security landscape shaped by a partial return to office but with a wide acceptance of hybrid and flexible working, as well zero-trust principles becoming mainstream, increasingly complex digital landscapes, and a geopolitical situation marred by Russia’s invasion of Ukraine.
These new challenges have been accompanied by more familiar threats vectors, with ransomware remaining rampant, and the growing commercial availability of offensive cyber tools leading a persistent stream of low-sophistication cyber crime becoming a thorn in the side of CISOs and security teams.
But the cyber landscape is constantly changing, and in what follows, we look at five key predictions, pulled from a range of analysts and experts across the Darktrace team, that we expect to see emerge in 2023.
1) Attacker tradecraft centers on identity and MFA
It wasn’t just the recent Uber attack in which the victim’s Multi-Factor Authentication (MFA) was compromised; at the core of the vast majority of cyber incidents is the theft and abuse of legitimate credentials. In the case of Uber, we saw that MFA can be defeated, and with Okta, that the MFA companies themselves become targets – potentially as a mechanism to reduce its effectiveness in other customer environments.
Once considered a ‘silver bullet’ in the fight against credential stuffing, it hasn’t taken attackers long to find and exploit weaknesses in MFA and they will continue to do so in 2023. MFA will remain critical to basic cyber hygiene, but it will cease to be seen as a stand-alone ‘set and forget’ solution. Questions around accessibility and usability continue to dominate the MFA discussion and will only be amplified by increases in cloud and SaaS along with the dissolution of traditional on-prem networks.
Today and in the future, MFA should be viewed as one component of a wider zero trust architecture, one where behavior-based analytics are central to understanding employee behavior and authenticating the actions taken using certain credentials.
2) Continued ‘hacktivism’ from non-state actors complicates cyber attribution and security strategies
The so-called ‘vigilante’ approach to cyber geopolitics is on the rise. Recent attacks launched by groups such as Killnet, though limited in their operational impact, have not failed in their aim to dominate global headlines in light of the Russo-Ukraine conflict, mounting concerns that these citizen-led operations could become more destructive or that states could use these groups as a deniable proxy.
Yet claims that ‘Russia’ launched these attacks can be misleading and add fuel to an already complicated political fire. Cyber attribution and deciphering the extent of state-level tasking is difficult, with blurred lines between state-aligned, state-involved and state-directed increasing the risk of escalation, collateral and misattribution.
In 2023, ‘knowing thy enemy’ in cyber will be more complicated than ever before – but it is critical that organizations remain aware of the realities of cyber risk and cease to focus on the ‘boogie man’ of the internet that features in sensationalist reporting. Persistent, widely available, lower-sophistication malware and run-of-the-mill phishing campaigns statistically remain a greater global risk to corporations than the newest, most devious exploit kit or ransomware typically associated with APT groups. As it gets harder to name the enemy, we should see organizations moving away from the headlines and towards ensuring operational stability based on a bespoke understanding of their unique risk profile.
3) Crypto-jacking neglect gets dangerous
The hijacking of computer resources to mine cryptocurrencies is one of the fastest growing types of cyber-threats globally. These attacks are often overlooked as unthreatening ‘background noise’, but the reality is that any crypto-mining infection can turn into ransomware, data exfiltration or even an entry point for a human-driven attack at the snap of a finger.
To achieve the scale of deployment that crypto-jackers are looking for, illegitimate network access must have been enabled by something relatively low-cost – a pervasive software vulnerability or default, weak or otherwise compromised credentials. This means that the basics aren't being done right somewhere, and if a crypto-jacker could do it, what's stopping a ransomware actor from following the same path?
In 2023, crypto-jackers will get more savvy and we might start to see the detrimental effects of what is usually considered inevitable or negligible. Security leaders need to ask themselves: “How did this person get in?” – and shore up the easiest points of entry into their organization.
Companies should not live with rogue software and hackers siphoning off their resources – particularly as rising energy prices will mean a greater financial loss is incurred as a result of illicit crypto-mining.
4) Ransomware rushes to the cloud
Ransomware attacks are ever-evolving, and as cloud adoption and reliance continue to surge, attackers will continue to follow the data. In 2023, we are likely to see an increase in cloud-enabled data exfiltration in ransomware scenarios in lieu of encryption.
Third-party supply chains offer those with criminal intent with more places to hide and targeting cloud providers instead of a single organization gives attackers more bang for their buck. Attackers may even get creative by threatening third-party cloud providers – a tactic which already impacted the education sector in early October when the Vice Society ransomware gang blackmailed Los Angeles Unified (LAUSD), the second largest school district in the US, and published highly sensitive information, including bank details and psychological health reports of students on the darknet.
5) Recession requires CISOs to get frank with the board about proactive security
Cyber security is a boardroom issue, but with growing economic uncertainty, organizations are being forced to make tough decisions as they plan 2023 budgets.
Rising cyber insurance premiums are one thing, but as more underwriters introduce exclusions for cyber-attacks attributed to nation-states, organizations will struggle to see the value in such high premiums. Both insurance and compliance have long been seen as ways of ticking the ‘protection’ checkbox without achieving true operational assurance, and we need look no further than Colonial Pipeline to see that insurance cannot compensate for long-term business disruption and reputational damage.
In 2023, CISOs will move beyond just insurance and checkbox compliance to opt for more proactive cyber security measures in order to maximize ROI in the face of budget cuts, shifting investment into tools and capabilities that continuously improve their cyber resilience. With human-driven means of ethical hacking, pen-testing and red teaming remaining scarce and expensive as a resource, CISOs will turn to AI-driven methods to proactively understand attack paths, augment red team efforts, harden environments and reduce attack surface vulnerability. Maturity models and end-to-end solutions will also be critical, as well as frank communication between CISOs and the board about the efficacy of continuously testing defenses in the background.

How Abuse of ‘PerfectData Software’ May Create a Perfect Storm: An Emerging Trend in Account Takeovers



Amidst the ever-changing threat landscape, new tactics, techniques, and procedures (TTPs) seem to emerge daily, creating extreme challenges for security teams. The broad range of attack methods utilized by attackers seems to present an insurmountable problem: how do you defend against a playbook that does not yet exist?
Faced with the growing number of novel and uncommon attack methods, it is essential for organizations to adopt a security solution able to detect threats based on their anomalies, rather than relying on threat intelligence alone.
In March 2023, Darktrace observed an emerging trend in the use of an application known as ‘PerfectData Software’ for probable malicious purposes in several Microsoft 365 account takeovers.
Using its anomaly-based detection, Darktrace DETECT™ was able to identify the activity chain surrounding the use of this application, potentially uncovering a novel piece of threat actor tradecraft in the process.
Microsoft 365 Intrusions
In recent years, Microsoft’s Software-as-a-Service (SaaS) suite, Microsoft 365, along with its built-in identity and access management (IAM) service, Azure Active Directory (Azure AD), have been heavily targeted by threat actors due to their near-ubiquitous usage across industries. Four out of every five Fortune 500 companies, for example, use Microsoft 365 services [1].
Malicious actors typically gain entry to organizations’ Microsoft 365 environments by abusing either stolen account credentials or stolen session cookies [2]. Once inside, actors can access sensitive data within mailboxes or SharePoint repositories, and send out emails or Teams messages. This activity can often result in serious financial harm, especially in cases where the malicious actor’s end-goal is to elicit fraudulent transactions.
Darktrace regularly observes malicious actors behaving in predictable ways once they gain access to customer Microsoft 365 environment. One typical example is the creation of new inbox rules and sending deceitful emails intended to convince recipients to carry out subsequent actions, such as following a malicious link or providing sensitive information. It is also common for actors to register new applications in Azure AD so that they can be used to conduct follow-up activities, like mass-mailing or data theft. The registration of applications in Azure AD therefore seems to be a relatively predictable threat actor behavior [3][4]. Darktrace DETECT understands that unusual application registrations in Azure AD may constitute a deviation in expected behavior, and therefore a possible indicator of account compromise.
These registrations of applications in Azure AD are evidenced by creations of, as well as assignments of permissions to, Service Principals in Azure AD. Darktrace has detected a growing trend in actors creating and assigning permissions to a Service Principal named ‘PerfectData Software’. Further investigation of this Azure AD activity revealed it to be part of an ongoing account takeover.
‘PerfectData Software’ Activity
Darktrace observed variations of the following pattern of activity relating to an application named ‘PerfectData Software’ within its customer base:
- Actor signs in to a Microsoft 365 account from an endpoint associated with a Virtual Private Server (VPS) or Virtual Private Network (VPN) service
- Actor registers an application called 'PerfectData Software' with Azure AD, and then grants permissions to the application
- Actor accesses mailbox data and creates inbox rule
In two separate incidents, malicious actors were observed conducting their activities from endpoints associated with VPN services (HideMyAss (HMA) VPN and Surfshark VPN, respectively) and from endpoints within the Autonomous System AS396073 MAJESTIC-HOSTING-01.
In March 2023, Darktrace observed a malicious actor signing in to a Microsoft 365 account from a Kuwait-based IP address within the Autonomous System, AS198605 AVAST Software s.r.o. This IP address is associated with the VPN service, HMA VPN. Over the next couple of days, an actor (likely the same malicious actor) signed in to the account several more times from two different Nigeria-based endpoints, as well as a VPS-related endpoint and a HMA VPN endpoint.
During their login sessions, the actor performed a variety of actions. First, they created and assigned permissions to a Service Principal named ‘PerfectData Software’. This Service Principal creation represents the registration of an application called ‘PerfectData Software’ in Azure AD. Although the reason for registering this application is unclear, within a few days the actor registered and granted permission to another application, ‘Newsletter Software Supermailer’, and created a new inbox rule names ‘s’ on the mailbox of the hijacked account. This inbox rule moved emails meeting certain conditions to a folder named ‘RSS Subscription. The ‘Newsletter Software Supermailer’ application was likely registered by the actor to facilitate mass-mailing activity.
Immediately after these actions, Darktrace detected the actor sending out thousands of malicious emails from the account. The emails included an attachment named ‘Credit Transfer Copy.html’, which contained a suspicious link. Further investigation revealed that the customer’s network had received several fake invoice emails prior to this initial intrusion activity. Additionally, there was an unusually high volume of failed logins to the compromised account around the time of the initial access.

In a separate case also observed by Darktrace in March 2023, a malicious actor was observed signing in to a Microsoft 365 account from an endpoint within the Autonomous System, AS397086 LAYER-HOST-HOUSTON. The endpoint appears to be related to the VPN service, Surfshark VPN. This login was followed by several failed and successful logins from a VPS-related within the Autonomous System, AS396073 MAJESTIC-HOSTING-01. The actor was then seen registering and assigning permissions to an application called ‘PerfectData Software’. As with the previous example, the motives for this registration are unclear. The actor proceeded to log in several more times from a Surfshark VPN endpoint, however, they were not observed carrying out any further suspicious activity.

It was not clear in either of these examples, nor in fact any of cases observed by Darktrace, why actors had registered and assigned permissions to an application called ‘PerfectData Software’, and there do not appear to be any open-source intelligence (OSINT) resources or online literature related to the malicious usage of an application by that name. That said, there are several websites which appear to provide email migration and data recovery/backup tools under the moniker ‘PerfectData Software’.
It is unclear whether the use of ‘PerfectData Software’ by malicious actors observed on the networks of Darktrace customers was one of these tools. However, given the nature of the tools, it is possible that the actors intended to use them to facilitate the exfiltration of email data from compromises mailboxes.
If the legitimate software ‘PerfectData’ is the application in question in these incidents, it is likely being purchased and misused by attackers for malicious purposes. It is also possible the application referenced in the incidents is a spoof of the legitimate ‘PerfectData’ software designed to masquerade a malicious application as legitimate.
Darktrace Coverage
Cases of ‘PerfectData Software’ activity chains detected by Darktrace typically began with an actor signing into an internal user’s Microsoft 365 account from a VPN or VPS-related endpoint. These login events, along with the suspicious email and/or brute-force activity which preceded them, caused the following DETECT models to breach:
- SaaS / Access / Unusual External Source for SaaS Credential Use
- SaaS / Access / Suspicious Login Attempt
- SaaS / Compromise / Login From Rare Following Suspicious Login Attempt(s)
- SaaS / Email Nexus / Unusual Location for SaaS and Email Activity
Subsequent activities, including inbox rule creations, registration of applications in Azure AD, and mass-mailing activity, resulted in breaches of the following DETECT models.
- SaaS / Admin / OAuth Permission Grant
- SaaS / Compromise / Unusual Logic Following OAuth Grant
- SaaS / Admin / New Application Service Principal
- IaaS / Admin / Azure Application Administration Activities
- SaaS / Compliance / New Email Rule
- SaaS / Compromise / Unusual Login and New Email Rule
- SaaS / Email Nexus / Suspicious Internal Exchange Activity
- SaaS / Email Nexus / Possible Outbound Email Spam
- SaaS / Compromise / Unusual Login and Outbound Email Spam
- SaaS / Compromise / Suspicious Login and Suspicious Outbound Email(s)

In cases where Darktrace RESPOND™ was enabled in autonomous response mode, ‘PerfectData Software’ activity chains resulted in breaches of the following RESPOND models:
• Antigena / SaaS / Antigena Suspicious SaaS Activity Block
• Antigena / SaaS / Antigena Significant Compliance Activity Block
In response to these model breaches, Darktrace RESPOND took immediate action, performing aggressive, inhibitive actions, such as forcing the actor to log out of the SaaS platform, and disabling the user entirely. When applied autonomously, these RESPOND actions would seriously impede an attacker’s progress and minimize network disruption.

In addition, Darktrace Cyber AI Analyst was able to autonomously investigate registrations of the ‘PerfectData Software’ application and summarized its findings into digestible reports.

Conclusion
Due to the widespread adoption of Microsoft 365 services in the workplace and continued emphasis on a remote workforce, account hijackings now pose a more serious threat to organizations around the world than ever before. The cases discussed here illustrate the tendency of malicious actors to conduct their activities from endpoints associated with VPN services, while also registering new applications, like PerfectData Software, with malicious intent.
While it was unclear exactly why the malicious actors were using ‘PerfectData Software’ as part of their account hijacking, it is clear that either the legitimate or spoofed version of the application is becoming an very likely emergent piece of threat actor tradecraft.
Darktrace DETECT’s anomaly-based approach to threat detection allowed it to recognize that the use of ‘PerfectData Software’ represented a deviation in the SaaS user’s expected behavior. While Darktrace RESPOND, when enabled in autonomous response mode, was able to quickly take preventative action against threat actors, blocking the potential use of the application for data exfiltration or other nefarious purposes.
