Nothing to see集約サービスによる転載を除けば、無関係なフィードをまたぐ連携した攻撃キャンペーンは見られない。本日の項目には、Ivantiの悪用といずれのリークサイトの活動とを結び付けるものはなく、atlasのシグナルにあるKEVとランサムウェアの融合スコアはモデルの出力であり、これらの侵入のいずれかで特定のCVEが悪用された証拠ではない。holcim、chainalysis、northflankを含むいくつかの情報源間の一致は、2つのフィードが運んだ同一の記事である。被害側の詳細、潜伏期間、初期侵入経路は、対象期間のどこにも見られなかった。
At least three of N0n's five placeholder listings (Company #99 to #103) are replaced by named victims on ransomware.live or ransomlook.
Called Thu 22 Oct · due Sun 1 Nov
Only one named N0n victim appears (Digital Triumph, 31 Oct), and nothing ties it to the Company #99-#103 placeholders. The due date is today and three named victims are not shown.
UpTransportation — 2.1× its own prior share (72 claims, 34 expected)
UpEducation — 2.1× its own prior share (57 claims, 27 expected)
UpHealthcare — 1.2× its own prior share (109 claims, 87 expected)
DownAgriculture and Food Production — 0.7× its own prior share (23 claims, 34 expected)
23% of claims carry no sector label.
Brand churn
Of the 231 leak-site brands first seen since 2021-09-30, 76% were still claiming 30 days after their first post and 70% were still claiming 60 days after their first post and 68% were still claiming 90 days after their first post and 62% were still claiming 120 days after their first post (Kaplan-Meier; quiet = 60 days without a claim). 18% of the 212 old enough to judge posted on one day and never again; 39% made at least half their claims in their first week. New brands this month: 11 — newest: everstake (2026-10-29, 5 claims), Shiba (2026-10-29, 4 claims), Whitearmor (2026-10-23, 18 claims).
Brands born before coverage began are excluded (their true age is unknown); a rebrand counts as one brand going quiet and another being born.
Targeting
Over the last 180 days, among brands with at least 20 labelled claims: safepay put 33% of its claims on Germany (6.3× every other brand's share); N0n put 33% of its claims on Transportation (7.4× every other brand's share); SilentRansomGroup put 100% of its claims on Professional Services (6.0× every other brand's share). Widest spread: nightspire across 10.6 effective sectors.
Lift = the brand's share of a sector or country over every other brand's share in the same window; exact binomial tails, Bonferroni-adjusted for the categories tested. Claims with no sector or an Unknown/Other label are excluded.
Posting clock
Over the last 180 days, among brands with at least 30 claims: clop released 94% of its claims on Wednesdays, half of them in 13:00–15:59 UTC; safepay released 59% of its claims on Mondays, half of them in 19:00–19:59 UTC; akira posted only 1 of 199 claims at weekends and half its claims in 12:00–13:59 UTC; half of play's claims appeared in 18:00–20:59 UTC. Leak sites overall are 34% quieter per weekend day than per weekday.
all brands by hour of day, 00–23 UTC; half of all claims land in 12:00–19:59 UTC.
Times are when trackers first saw each claim on the leak site, in UTC: not the attack time, not the operator's clock, and a site that is only reachable at certain hours shows the same pattern; batch releases show as spikes. Hour-of-day concentration: Rayleigh test; weekday shares: exact binomial against every other brand, Bonferroni-adjusted.
Leak-site claims as discovered by trackers, not confirmed breaches. Surprise compares the last 7 days with the group's own prior 173 days (Poisson). Victim claims: ransomware.live and leak-site trackers
