The adage “teamwork makes dreamwork” extends to cybercriminals as effectively. To launch extra profitable cyberattacks, malicious actors with completely different specialised expertise have conglomerated to kind Cybercrime as a Service (CaaS).
We’re now seeing individuals and teams specialise in numerous elements of the assault lifecycle. Which means that we’re seemingly going to see much less errors made resulting in detections, and we should always count on a number of teams colonizing an contaminated community.
Inside CaaS there are 4 sorts of cyber crime teams:
Pondering from an incident response mentality, this implies they should establish these completely different teams finishing particular points of the general assault, making it harder to detect and cease assaults. Figuring out the generally used ways, strategies, and procedures (TTPs) will help CISOs and safety leaders strengthen their cybersecurity technique and decrease danger.
Kinds of Cyber Crime Teams
Pattern Micro Analysis analyzed Entry as a Service (AaaS), a service providing within the undergrounds whereby malicious actors are promoting entry into enterprise networks.
AaaS consists of people and teams that use quite a few strategies to acquire distant entry into a company’s community. There are three sorts of AaaS sellers:
Opportunistic actors who seen a requirement and determined to show a revenue.
Devoted sellers—their full-time job is gaining and promoting entry. They even market their companies and leverage their in depth community to make gross sales.
On-line outlets, which generally solely assure entry to a single machine, not a community or company.
Teams who specialise in having access to networks after which purposely promoting it to others are extra worrisome as their entry is often stable and ensures their patrons that they’ll ship their service. Each sorts of AaaS actors could be troublesome, however the latter is definitely the group that can hassle extra organizations because of the complexity of attributing the preliminary attacker.

Credited as one of many causes ransomware assaults proceed to extend, RaaS has enabled less-skilled hackers to launch pricey assaults on giant organizations – like SolarWinds – by offering the required instruments and strategies.
This newfound accessibility has led to a dramatic 63.2% enhance of RaaS extortion teams within the first quarter of 2022. The Pattern Micro Analysis 2022 Midyear Cybersecurity Report discovered that over 50 lively RaaS and extortion teams victimized greater than 1,200 organizations within the first half of 2022.
LockBit, Conti, and Blackhat have been essentially the most outstanding RaaS menace actors within the first six months, however new ransomware households like Black Basta and SolidBit are rising.

Dependable website hosting companies that may stand up to abuse complaints and legislation enforcement takedown requests are essential to holding a cybercriminal operation working easily and covertly. Bulletproof internet hosting companies are primarily leased hideouts the place malicious actors can retailer recordsdata and even the malware vital for his or her assault campaigns.
Void Griffin provided its first fast-flux bulletproof internet hosting service in 2015 and has been house to many alternative APT teams and outstanding malware households since.

Cybercriminals have turned to crowdsourcing their offensive analysis and growth processes to search out new assault strategies. This comparatively new sort of cyber crime had elevated within the final two years. Pattern Micro Analysis noticed an uptick in malware actors holding public contests within the felony underground to search out new inventive assault strategies.
Some contests will search expertise (like The Voice or American Idol), however these are rarer. Most contests are looking for information; they’re on the lookout for technical articles on new assault strategies, vulnerabilities, and so on. And sure, a prize – and even a number of – are awarded to the very best or most revolutionary technical proposal. Oftentimes the requests are extra generic versus limiting the subject to a particular area.
Pattern Micro Analysis anticipates a rise within the variety of crowdsourcing competitions, which in flip will speed up felony innovation. And such evolutions don’t have to be main; small tactical wins can enable criminals to bypass present defenses.

Cybersecurity Protection Methods
So, how are you going to tackle the several types of cyber crime teams? Sadly, enterprises can’t bounce into the cybercriminal underground and cease crowdsourcing. However they’ll work to forestall or restrict the scope of the result by implementing a cybersecurity protection technique that focuses on detecting and stopping the preliminary entry breach.
The sooner you possibly can detect the preliminary entry of an assault, the extra seemingly you possibly can forestall the next elements of the assault lifecycle from occurring, like ransomware. Listed here are different elements to think about when creating an efficient safety technique:
1. Companion with a safety vendor that leverages world menace analysis to continuously monitor public breaches and bulletproof internet hosting companies within the felony underground. This ensures your options are optimized to defend towards the most recent threats. Moreover, by proactively finding and blocking the bulletproof internet hosting infrastructure, defenders can block assaults within the earlier phases of the kill chain.
2. Comply with a zero belief method to community safety by implementing a SASE structure. SASE consists of Zero Belief Community Entry (ZTNA), Safe Internet Gateway (SWG), and Cloud Entry Safety Dealer (CASB) capabilities to strengthen safety and management throughout the assault floor.
3. Set up an incident response (IR) playbook to floor any safety gaps. Ensure your IR groups or vendor perceive the multi-attacker state of affairs and know the place to focus their efforts.
4. Set up a powerful patch administration technique to restrict the scope of exploits. This could embrace figuring out essentially the most related patches, making a zero-day exploit plan, speaking with distributors, and using digital patching.
5. Leverage trusted cybersecurity frameworks for password finest practices just like the Nationwide Institute of Requirements and Know-how (NIST) and the European Union Company for Cybersecurity (ENISA). The Middle of Web Safety (CIS) gives thorough steerage on prioritization and useful resource administration, in addition to filling any gaps that may very well be uncovered by attackers.
6. Use a unified cybersecurity platform with XDR capabilities to assist consolidate and correlate menace exercise throughout endpoints, cloud, networks, e-mail, and so on., for extra visibility.
