What is CrowdSec?

CrowdSec's 1.8.2 candidates let operators write their own bot fingerprints.

The bot detection introduced with 1.8 is now being opened to customization. The 1.8.2 candidates add custom JavaScript fingerprinting, a cscli bot subcommand and a FlagSubmission helper, and rc2 adds a RateLimit helper for the WAF plus a cookie option for embedded contexts. Operational work runs alongside it: a cs_features metric, optional limits on concurrent decision streams and TLS certificate reloads.

What is Snort 3?

Snort 3.12.4 pairs a long memory-safety pass with detection speed work

Snort 3.12.4.0 rolls up changes since 3.12.2.0 and is the first release in this feed since April. It fixes reject and react actions in IDS mode, a TLS decryption bypass case with adaptive profiles, and many bounds and memory issues across dce_rpc, dns, decompress and appid. It also reorganizes detection data for cache efficiency and expands extractor logging.

CrowdSec's 1.8.2 candidates let operators write their own bot fingerprints.

◆ Current state

The bot detection introduced with 1.8 is now being opened to customization. The 1.8.2 candidates add custom JavaScript fingerprinting, a cscli bot subcommand and a FlagSubmission helper, and rc2 adds a RateLimit helper for the WAF plus a cookie option for embedded contexts. Operational work runs alongside it: a cs_features metric, optional limits on concurrent decision streams and TLS certificate reloads.

◆ Where it's heading

The WAF remains the center of gravity, and the direction is programmability. RateLimit, SkipProcessing and the fingerprinting hooks give rule authors primitives rather than fixed behavior. The LAPI changes point at larger deployments, where decision streaming puts load on the central API.

◆ Prediction

The final 1.8.2 is dated 26 October on GitHub, though it has not reached this feed yet. Whether fingerprint data ever joins the community blocklist remains unanswered in these notes.

Snort 3.12.4 pairs a long memory-safety pass with detection speed work

◆ Current state

Snort 3.12.4.0 rolls up changes since 3.12.2.0 and is the first release in this feed since April. It fixes reject and react actions in IDS mode, a TLS decryption bypass case with adaptive profiles, and many bounds and memory issues across dce_rpc, dns, decompress and appid. It also reorganizes detection data for cache efficiency and expands extractor logging.

◆ Where it's heading

The two earlier threads are both still present, but memory safety now outweighs new appid capability. A notable share of the fixes bound inputs or cap unbounded growth, in DNS over TCP, VBA decompression and SMB transactions, which suggests systematic hardening. Detection hot-path tuning is newer here, as are extractor changes that bring output closer to connection logging.

◆ Prediction

Expect the same hardening pattern to continue across parsers, with extractor output the most likely area for further visible change. The six-month gap in this feed leaves the release cadence unclear.
