Opposite to widespread notion, small and medium-sized companies (SMBs) are sometimes the goal of cyberattacks. That’s comprehensible, as within the US and UK, they comprise over 99% of companies, a majority of personal sector jobs and round half of earnings. However in the event you’re an IT or enterprise chief at a smaller group, easy methods to do extra with much less is a important problem.
With fewer assets to commit to cyber-risk mitigation, the main target have to be on successfully prioritizing the place they’re directed. Because the current ESET SMB Digital Safety Sentiment Report discovered, 69% of SMBs reported a breach or a robust indication of 1 previously 12 months, highlighting the necessity for pressing motion.
For this, you want onerous information. The place are attackers focusing their efforts? Who’re they? And the way profitable are they being? Whereas there are numerous sources of such data, one of the rigorous analyses of the menace panorama is the annual Verizon Knowledge Breach Investigations Report (DBIR). Its newest version is a gold mine of data that SMBs can use to reinforce safety technique.
The place are the principle cybersecurity threats to enterprise?
The 2023 DBIR relies on evaluation of 16,312 incidents, of which round a 3rd, or 5,199, had been confirmed as information breaches. One of many advantages of this long-running sequence, now in its sixteenth 12 months, is that readers can even consider present traits in opposition to historic patterns. So what’s of curiosity this version?
Listed below are some key takeaways for SMBs:
Assault surfaces converge: Regardless of their many variations, SMBs and bigger organizations are literally changing into extra alike, based on Verizon. More and more they use the identical infrastructure and providers, resembling cloud-based software program, which implies their assaults surfaces share extra in widespread than ever earlier than. In actual fact, when it comes to elements like menace actor varieties, motivations and assault patterns, the report’s authors admit “there may be so little distinction primarily based on organizational measurement that we had been hard-pressed to make any distinctions in any way.” For instance, system intrusion, social engineering and fundamental net utility assaults account for 92% of SMB breaches at the moment, in contrast with a barely decrease share (85%) in massive companies that boast over 1,000 staff. Moreover, 94% of menace actors are exterior, in comparison with 89% in massive organizations, and 98% of breaches are financially motivated (versus 97%).
Exterior attackers are the most important menace: Third-party menace actors account for 83% of breaches at the moment general, rising to 94% in SMB assaults. That’s in comparison with a 19% of general breaches the place inside actors had been accountable, falling to simply 7% for SMBs. Curiously, 2% of SMB breaches may very well be traced to “a number of” sources, which Verizon claims means a mix of inside, exterior and companions working in collusion. Nevertheless, general insider danger is minimal for smaller companies.
Monetary motivation is primary: The overwhelming majority (95%) of breaches are financially motivated, growing to 98% for SMB assaults. It’s a transparent indication that organized crime versus nation states is the highest menace to small companies. In actual fact, espionage accounts for simply 1% of SMB breaches.
People are the weakest hyperlink: The primary technique of entry into sufferer networks is stolen credentials (49%), adopted by phishing (12%) and exploitation of vulnerabilities (5%). This means staff as a persistently weak hyperlink within the safety chain. In actual fact, people play a task in 74% of breaches. This may very well be due to make use of of stolen credentials and phishing, or different strategies like misconfiguration or misdelivery of delicate information. This additionally chimes with the 2022 ESET SMB Digital Safety Sentiment Report, which finds a scarcity of worker cyber-awareness (84%) as the highest driver of danger.
Enterprise e-mail compromise (BEC) doubles: The quantity of “pretexting” circumstances (which Verizon says is akin to BEC) doubled throughout all incidents for the reason that earlier DBIR. It has made pretexting a much bigger menace than phishing, though the latter continues to be extra prevalent in precise information breaches. In BEC, the sufferer is tricked into wiring massive sums to an attacker-controlled checking account. Any such fraud is one other signal of how essential the human issue is in assaults. Though there are not any SMB-specific stats right here, the median quantity stolen by way of BEC has elevated to $50,000.
Ransomware stays a prime menace as prices surge: Ransomware is now a characteristic of 1 / 4 (24%) of breaches, due to double extortion techniques which imply information is stolen earlier than it’s encrypted. That share just isn’t a lot modified from final 12 months, however Verizon warned that the menace “is ubiquitous amongst organizations of all sizes and in all industries.” Median prices greater than doubled yearly to $26,000, though that is prone to be an underestimate.
System intrusion tops assault varieties: The highest three assault patterns for SMB breaches so as are system intrusion, social engineering and fundamental net app assaults. Collectively they symbolize 92% of breaches. System intrusion refers to “complicated assaults that leverage malware and/or hacking to attain their aims,” together with ransomware.

The query is how one can flip this perception into motion. Listed below are some greatest follow controls which may also help to mitigate system intrusion assaults:
Safety consciousness and coaching applications designed to mitigate numerous threats, together with the insider menace.
Knowledge restoration processes which may also help within the aftermath of ransomware assaults.
Entry management administration, together with processes and instruments to create, assign, handle and revoke entry credentials and privileges. This might embrace multi-factor authentication (MFA).
Incident response administration to quickly detect and reply to assaults.
Software software program safety to stop, detect and remediate software program flaws.
Penetration testing designed to reinforce resilience.
Vulnerability administration to assist mitigate different menace varieties resembling net utility assaults.
Endpoint detection and response (EDR), prolonged detection and response (XDR) or managed detection and response (MDR), which 32% of SMBs use and one other 33% plan to make use of within the subsequent 12 months, based on ESET.
That is not at all a complete record. Nevertheless it’s a begin. And sometimes that’s half the battle.
In an effort to study extra about SMBs’ perceptions of cybersecurity, together with about the place the rising safety wants are driving them, head over to the 2022 ESET SMB Digital Safety Sentiment Report.
