Here are three of the worst breaches, attacker ways and strategies of 2022, and the safety controls that may present efficient, enterprise safety safety for them.
#1: 2 RaaS Attacks in 13 Months
Ransomware as a service is a kind of assault through which the ransomware software program and infrastructure are leased out to the attackers. These ransomware companies could be bought on the darkish internet from different risk actors and ransomware gangs. Common buying plans embrace shopping for the whole software, utilizing the present infrastructure whereas paying per an infection, or letting different attackers carry out the service whereas sharing income with them.
In this assault, the risk actor consists of one of the crucial prevalent ransomware teams, specializing in entry through third events, whereas the focused firm is a medium-sized retailer with dozens of websites within the United States.
The risk actors used ransomware as a service to breach the sufferer’s community. They had been in a position to exploit third-party credentials to achieve preliminary entry, progress laterally, and ransom the corporate, all inside mere minutes.
The swiftness of this assault was uncommon. In most RaaS circumstances, attackers often keep within the networks for weeks and months earlier than demanding ransom. What is especially attention-grabbing about this assault is that the corporate was ransomed in minutes, without having for discovery or weeks of lateral motion.
A log investigation revealed that the attackers focused servers that didn’t exist on this system. As it seems, the sufferer was initially breached and ransomed 13 months earlier than this second ransomware assault. Subsequently, the primary attacker group monetized the primary assault not solely by means of the ransom they obtained, but in addition by promoting the corporate’s community data to the second ransomware group.
In the 13 months between the 2 assaults, the sufferer modified its community and eliminated servers, however the brand new attackers weren’t conscious of those architectural modifications. The scripts they developed had been designed for the earlier community map. This additionally explains how they had been in a position to assault so rapidly – they’d loads of details about the community. The predominant lesson right here is that ransomware assaults could be repeated by completely different teams, particularly if the sufferer pays nicely.
“RaaS assaults comparable to this one are instance of how full visibility permits for early alerting. A worldwide, converged, cloud-native SASE platform that helps all edges, like Cato Networks offers full community visibility into community occasions which might be invisible to different suppliers or could go underneath the radar as benign occasions. And, with the ability to absolutely contextualize the occasions permits for early detection and remediation.
#2: The Critical Infrastructure Attack on Radiation Alert Networks
Attacks on crucial infrastructure have gotten extra frequent and extra harmful. Breaches of water provide crops, sewage techniques and different such infrastructures might put tens of millions of residents susceptible to a human disaster. These infrastructures are additionally changing into extra weak, and assault floor administration instruments for OSINT like Shodan and Censys permit safety groups to search out such vulnerabilities with ease.
In 2021, two hackers had been suspected of focusing on radiation alert networks. Their assault relied on two insiders that labored for a 3rd occasion. These insiders disabled the radiation alert techniques, considerably debilitating their capability to watch radiation assaults. The attackers had been then in a position to delete crucial software program and disable radiation gauges (which is a part of the infrastructure itself).
“Unfortunately, scanning for weak techniques in crucial infrastructure is simpler than ever. While many such organizations have a number of layers of safety, they’re nonetheless utilizing level options to try to defend their infrastructure fairly than one system that may look holistically on the full assault lifecycle. Breaches are by no means only a phishing downside, or a credentials downside, or a weak system downside – they’re at all times a mix of a number of compromises carried out by the risk actor,” mentioned Etay Maor, Sr. Director of Security Strategy at Cato Networks.
#3: The Three-Step Ransomware Attack That Started with Phishing
The third assault can be a ransomware assault. This time, it consisted of three steps:
1. Infiltration – The attacker was in a position to achieve entry to the community by means of a phishing assault. The sufferer clicked on a hyperlink that generated a connection to an exterior website, which resulted within the obtain of the payload.
2. Network exercise – In the second part, the attacker progressed laterally within the community for 2 weeks. During this time, it collected admin passwords and used in-memory fileless malware. Then on New Year’s Eve, it carried out the encryption. This date was chosen because it was (rightfully) assumed the safety group could be off on trip.
3. Exfiltration – Finally, the attackers uploaded the information out of the community.
In addition to those three predominant steps, extra sub-techniques had been employed throughout the assault and the sufferer’s level safety options weren’t in a position to block this assault.
“A a number of choke level strategy, one that appears horizontally (so to talk) on the assault fairly than as a set of vertical, disjointed points, is the way in which to reinforce detection, mitigation and prevention of such threats. Opposed to common perception, the attacker must be proper many occasions and the defenders solely have to be proper simply as soon as. The underlying applied sciences to implement a a number of choke level strategy are full community visibility through a cloud-native spine, and a single cross safety stack that is based mostly on ZTNA.” mentioned Etay Maor, Sr. Director of Security Strategy at Cato Networks.
How Do Security Point Solutions Stack Up?
It is frequent for safety professionals to succumb to the “single level of failure fallacy”. However, cyber-attacks are refined occasions that hardly ever contain only one tactic or method which is the reason for the breach. Therefore, an all-encompassing outlook is required to efficiently mitigate cyber-attacks. Security level options are an answer for single factors of failure. These instruments can determine dangers, however they won’t join the dots, which might and has led to a breach.
Here’s Watch Out for within the Coming Months
According to ongoing safety analysis performed by Cato Networks Security Team, they’ve recognized two extra vulnerabilities and exploit makes an attempt that they suggest together with in your upcoming safety plans:
1. Log4j
While Log4j made its debut as early as December of 2021, the noise its making hasn’t died down. Log4j remains to be being utilized by attackers to use techniques, as not all organizations have been in a position to patch their Log4j vulnerabilities or detect Log4j assaults, in what is called “digital patching”. They suggest prioritizing Log4j mitigation.
2. Misconfigured Firewalls and VPNs
Security options like firewalls and VPNs have turn out to be entry factors for attackers. Patching them has turn out to be more and more troublesome, particularly within the period of structure cloudification and distant work. It is really useful to pay shut consideration to those parts as they’re more and more weak.
How to Minimize Your Attack Surface and Gain Visibility into the Network
To cut back the assault floor, safety professionals want visibility into their networks. Visibility depends on three pillars:
- Actionable data – that can be utilized to mitigate assaults
- Reliable data – that minimizes the variety of false positives
- Timely data – to make sure mitigation occurs earlier than the assault has an influence
Once a corporation has full visibility to the exercise on their community they’ll contextualize the information, determine whether or not the exercise witnessed must be allowed, denied, monitored, restricted (or another motion) after which have the flexibility to implement this resolution. All these parts should be utilized to each entity, be it a person, system, cloud app and so forth. All the time in every single place. That is what SASE is all about.
