In the second half of June 2023, I collected 178 events (corresponding to 11.87 events/day), a result in line with the first timeline of June, when there were 177 events for a daily average of 11.80.

And unsurprisingly, even this timeline was characterized by the massive exploitation of the CVE-2023-34362 MOVEit vulnerability by the Clop (AKA Cl0p) ransomware syndicate, leading to a spike on the percentage of attacks carried out exploiting vulnerabilities, with the new unprecedented value of 29.8% (53 out of 178 events) that beats the previous record of 28.4% tracked during the first half of June. The other obvious consequence was the increase of the percentage of events directly or indirectly characterized by ransomware, soaring to 40.3% (72 out of 178 events) from 34.3% of the previous timeline.

The good news is that, apparently for this fortnight, the fintech sector did not suffer massive breaches, with the partial exception of an undisclosed cryptocurrency exchange in Japan that was targeted by a threat actor dubbed REF9134 through the MacOS JokerSpy backdoor.

There were two mega breaches during this fortnight, and unsurprisingly one of them (the one affecting PBI Research Services) was due to the massive exploitation campaign carried out by the Cl0p ransomware gang exploiting the CVE-2023-34362 MOVEit vulnerability. The other breach affected an undisclosed Italian airport that suffered the leak of 7.8 million records.

The Cyber Espionage front was always hot, with multiple campaigns unearthed and carried out by known threat actors such as APT15, APT28, APT29, APT37, Mustang Panda, and the Lazarus Group, just to mention a few.

And as always, this brief summary is closed by a quick mention to the attacks launched by hacktivists: the pro-Russian threat actors of NoName057(16) targeted several government websites in Sweden, and their companions from Anonymous Sudan took down some targets in the U.S.

My suggestion is always the same: browse the timeline, and obviously thanks for sharing it and supporting my work in spreading the risk awareness across the community. As always, don’t forget to follow @paulsparrows on Twitter, or even connect on Linkedin, for the latest updates.

Creating the timelines is a very time-consuming task.
