Despite the overall level of activity remains quite high, the second cyber attack timeline of September 2023 shows a considerable decrease in terms of events compared to the first half of the same month. In the second half of September I collected 165 events, corresponding to 11 events/day, down from 215 of the first fortnight (14.33 events/day) and close to the values of August.

Ransomware continues to characterize the threat landscape, and consequently malware attacks lead the chart of the attack techniques with 35.2% (58 out of 165 events,) an important number that is however lower than 39.7% (83 out of 209 events) of the previous timeline. Instead the impact of vulnerabilities is in line with the previous period (17.57%, corresponding to 29 out of 165 events, vs 17.2% of the previous fortnight). And yes, there are still impacts of the massive MOVEit attack with new organizations disclosing breaches stemmed by the CVE-2023-34362 Vulnerability.

And even in this timeline we found several massive hacks against organizations operating in the fintech space, for example Mixin Network lost the equivalent of $200 million, making it the largest hack suffered in 2023 (so far). Other “minor” incidents include the loss of $7.9 million worth from crypto exchange HTX, and the loss of “only” $238,000 worth from Balancer.

And the list of mega breaches continued to grow also in the second half of September: McLaren HealthCare suffered an ALPHV/BlackCat ransomware attack compromising the information of 2.5 million individuals, and more than 2 million Pakistani citizens had their data compromised when attackers got access to a private company-made database used by hundreds of restaurants.

Threat actors driven by cyber espionage were quite active in this fortnight with multiple operations carried out by known attackers such as APT29, APT34, APT36, the Lazarus group, but also new mysterious threat actors such as Sandman, targeting telecommunication service providers in the Middle East, Western Europe, and South Asia. But this month the list is really too long to be summarized in a few words.

In terms of hacktivism: the pro-Russia hacktivists from NoName057(16) were particularly active against organizations in two countries in particular: Canada and Italy.

Of course, my suggestion is always the same: browse the timeline, and obviously share it to support my work in spreading the risk awareness across the community. And don’t forget to follow @paulsparrows on Twitter, or even connect on Linkedin, or Mastodon for the latest updates.

Creating the timelines is a very time-consuming task.
