The adage “teamwork makes dreamwork” extends to cybercriminals as nicely. To launch extra profitable cyberattacks, malicious actors with totally different specialised abilities have conglomerated to kind Cybercrime as a Service (CaaS).
We’re now seeing individuals and teams concentrate on 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 5 sorts of cybercrime teams:
Considering from an incident response mentality, this implies they should establish these totally different teams finishing particular features 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 reduce danger.
Kinds of Cyber Crime Teams
Development 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 corporation’s community. There are three sorts of AaaS sellers:
Opportunistic actors who observed 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 intensive community to make gross sales.
On-line outlets, which generally solely assure entry to a single machine, not a community or company.
Teams who concentrate on getting access to networks after which purposely promoting it to others are extra worrisome as their entry is normally strong and ensures their consumers that they’ll ship their service. Each sorts of AaaS actors might be troublesome, however the latter is definitely the group that may bother 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 massive organizations – like SolarWinds – by offering the required instruments and strategies.
This newfound accessibility has led to a dramatic 63.2% improve of RaaS extortion teams within the first quarter of 2022. The Development Micro Analysis 2022 Midyear Cybersecurity Report discovered that over 50 energetic RaaS and extortion teams victimized greater than 1,200 organizations within the first half of 2022.
LockBit, Conti, and Blackhat had been probably the most outstanding RaaS menace actors within the first six months, however new ransomware households like Black Basta and SolidBit are rising.

Dependable webhosting companies that may stand up to abuse complaints and regulation enforcement takedown requests are crucial to holding a cybercriminal operation working easily and covertly. Bulletproof internet hosting companies are basically leased hideouts the place malicious actors can retailer recordsdata and even the malware crucial for his or her assault campaigns.
Void Griffin supplied its first fast-flux bulletproof internet hosting service in 2015 and has been house to many various 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. Development Micro Analysis noticed an uptick in malware actors holding public contests within the legal underground to search out new artistic 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 in search of technical articles on new assault strategies, vulnerabilities, and many others. 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 selected area.
Development Micro Analysis anticipates a rise within the variety of crowdsourcing competitions, which in flip will speed up legal innovation. And such evolutions don’t should be main; small tactical wins can permit criminals to bypass present defenses.

In response to Verizon, 78% of organizations skilled email-based ransomware assaults in 2021. Not solely is phishing widespread, however it’s pricey — the email-based assault price massive enterprises nearly $15 million USD yearly.
Like RaaS or Aaas, this assault method permits anybody with even entry-level information of the cybersecurity panorama to deploy a phishing assault. Cybercriminals act as a service supplier on behalf of others in trade for cost and/or a portion of a ransomware payout.
Wannabe scammers may buy a phishing package, which embrace the capabilities and instruments required to launch an assault corresponding to electronic mail templates, spoof web site templates, tact lists of potential targets, and many others.

Cybersecurity Protection Methods
So, how will you tackle the several types of cyber crime teams? Sadly, enterprises can’t leap into the cybercriminal underground and cease crowdsourcing. However they’ll work to stop 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 may detect the preliminary entry of an assault, the extra seemingly you may forestall the next parts of the assault lifecycle from occurring, like ransomware. Listed below are different parts to contemplate when creating an efficient safety technique:
1. Accomplice with a safety vendor that leverages world menace analysis to continuously monitor public breaches and bulletproof internet hosting companies within the legal underground. This ensures your options are optimized to defend in opposition to the newest 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 Net 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. Make sure that your IR groups or vendor perceive the multi-attacker situation and know the place to focus their efforts.
4. Set up a robust patch administration technique to restrict the scope of exploits. This could embrace figuring out probably the most related patches, making a zero-day exploit plan, speaking with distributors, and using digital patching.
5. Leverage trusted cybersecurity frameworks for password greatest practices just like the Nationwide Institute of Requirements and Know-how (NIST) and the European Union Company for Cybersecurity (ENISA). The Heart of Web Safety (CIS) gives thorough steering on prioritization and useful resource administration, in addition to filling any gaps that could possibly be uncovered by attackers.
6. Use a unified cybersecurity platform with XDR capabilities to assist consolidate and correlate menace exercise throughout endpoints, cloud, networks, electronic mail, and many others., for extra visibility.
