Microsoft analysis of about 383,000 CVEs disclosed from 1999 to September 2026, of which about 2,000 (0.5%) were exploited in the wild. Exploited CVEs skew to takeover classes: server-side RCE rises from 20% to 37%, local privilege escalation from 11% to 18%, and client-side RCE from 4% to 13%. Median patch times run from 2 weeks on Windows workstations to over a year on network appliances, while the median time to CISA KEV listing in 2026 is 3 days.

XCPE is an Android TV box botnet of more than 1.3 million devices, which Google's Threat Intelligence Group attributes with high confidence to manufacturer Videostrong Technology, who preinstalled a system-level backdoor in firmware. The backdoor (x.cpe, com.oemservice) used an MQTT broker for commands and loaded ad fraud and residential proxy modules. Google took down C2 servers tied to 10 million more devices and banned Videostrong from certified Android devices.

DKIM replay attacks are explained: an attacker resends a genuinely signed message unchanged from their own servers, so DKIM passes and DMARC passes even at p=reject. The post shows how to tell replay from spoofing or a legitimate relay using DMARC rua reports, why rotating a key without removing the old public key from DNS leaves messages replayable, and how Amazon SES (BYODKIM vs Easy DKIM), Route 53 and CloudWatch support detection and response. It ends with an ordered incident-response procedure.

BTCPay Server, an open-source self-hosted cryptocurrency payment processor, reports attackers draining hot wallets on instances running version 2.4.1 (July 23, 2026) or earlier. Attackers logged in as administrators on versions older than 2.4.2. Users should update to 2.4.7; the exploited flaw is not disclosed. An October 29 critical vulnerability found by Anthropic's Frontier OSS scanner prompted 2.4.7. The August 7 release 2.4.2 had already warned of an exploited LND credential exposure.

CVE-2026-97229 is a maximum-severity integer overflow in GitLab's CI/CD Regular Expression Compiler that lets an unauthenticated attacker run code via a crafted regex in pipeline configuration. GitLab patched it on 12 October 2026 in versions 19.4.2, 19.3.5 and 19.2.8. CISA added it to KEV, and Shadowserver tracks over 1,000 unpatched servers, plus 11,300 exposed to the related CVE-2026-110264.

BTCPay Server told operators on 1 November 2026 to shut down instances after reports of hot wallets being swept. The project later said the attack targeted versions 2.4.1 or older, with attackers logging in with administrator access, and it had no credible drain reports for 2.4.7. Release 2.4.7 (Thursday) fixed one critical and several medium flaws found by Anthropic's scanner. The number of servers affected and the amount stolen are not stated.

Volexity attributed the chain to UTA0576, which ran no malware, re-exploited the device per command and tampered with logs, evading Ivanti's Integrity Checker Tool. CISA added CVE-2026-104935 to KEV, and Shadowserver tracks over 5,000 exposed instances.

Alpine Linux rebuilt its GitLab server and reset all passwords after attackers tried to exploit CVE-2026-97229, a maximum-severity integer overflow in the Onigmo regex engine bundled with Ruby, on October 20-21. Eight worker crashes occurred and four were partially successful. Missing logs and outbound connection records meant compromise could not be ruled out. Alpine had run GitLab 19.3.4, then 19.3.6, which lacked the Ruby patch; the fixed image is alpinelinux/gitlab:19.3.6 with Ruby 3.3.13.

CVE-2026-98432 is a use-after-free race condition in the Linux kernel IPv4 TCP code (tcp_v4_syn_recv_sock, ireq_opt), affecting kernels back to 4.4 and rated 9.8 by the kernel CVE team (Red Hat rates it 5.9). Anthropic researchers say an unreleased Claude model built an exploit that bypassed KASLR and got remote root on an MPTCP listener in about 53 minutes. The article lists distro patch status and CIQ's nftables mitigation for IP options; disabling MPTCP alone does not help. No in-the-wild exploitation is reported.

The SAIL Framework from Pillar Security is a seven-phase, lifecycle-oriented method for securing AI systems. The phases are AI policy and safe experimentation, AI asset discovery, AI security posture management, AI red teaming, runtime guardrails, sandboxed execution for agents and MCP servers, and AI activity tracing. It argues for a "Shift Up" approach that protects the business logic AI controls, and it is meant to sit on top of existing standards.

Oversecured's Android security checklist on arbitrary file theft from an app's private storage. It covers implicit intents (PICK, GET_CONTENT) returning file:// or content:// URIs, SEND/SEND_MULTIPLE share activities, exported and non-exported FileProviders, path traversal via Uri.getLastPathSegment, WebView, and local NanoHTTPD servers. Each case has vulnerable code, an attacker PoC and fixes such as /proc/self/fd path checks and narrow files-path entries.

An Oversecured Head of Engineering, coming from 20 years of web work, describes four mobile security risks that became concrete after seeing real production apps. These are old vulnerable binaries that stay installed after a fix, secrets embedded in client code, Keychain/Keystore guarantees that are weaker than assumed with tokens leaking via logs, and deep links or exported components acting as public endpoints. It ends with advice: test the shipped artifact, verify the full data lifecycle, and build server-side containment.

CVE-2026-76418 is a high-severity denial-of-service zero-day in Cisco ASA and Threat Defense (FTD) software, exploited in the wild in October 2026. Unauthenticated attackers send a crafted request to the SSL VPN (webvpn) when secondary authentication is set on a tunnel group, causing a device reload. Cisco offers no workaround besides disabling secondary authentication on tunnel groups. Shadowserver sees over 51,000 exposed ASA SSL VPN devices.

Electrum 4.8.3, released 24 October 2026, fixes a high-severity flaw in the Bitcoin wallet. Rogue servers could suppress a real payment and inject a fake unconfirmed transaction paying an attacker, so a user's fee-bump became the first transaction broadcast. The fix verifies signatures on wallet-owned inputs, but incoming transactions from external senders stay unverified. One user lost funds on 18 October.

PHP2Shell exploitation (CVE-2026-109618, CVE-2026-109619) reached working shells on 24 October 2026, when Perplexity researcher Adel Karimi's honeypots (PHP 8.4.26, Apache mod_php, single worker) logged 35 shells across three servers. Attackers used a four-stage HTTP chain: memory exhaustion, memory leak, then shell command execution, matching a public PoC. No second-stage payload was seen, and CISA had not added the flaws to KEV as of 26 October.

Electrum, a Bitcoin software wallet, disclosed on 24 October 2026 a flaw where malicious servers swapped pending transactions for fake ones with invalid signatures that the wallet did not check. When users chose Replace-by-Fee to raise the fee, Electrum signed a valid replacement paying the attacker, and at least one user lost funds. Version 4.8.3 adds signature checks; users of only trusted or self-run servers were not exposed.

Electrum 4.8.3, released 24 October 2026, fixes a flaw where a malicious server replaces a user's unconfirmed payment with a conflicting transaction carrying invalid signatures. If the user then bumps the fee with replace-by-fee, the wallet signs a payment to the attacker. One of two reporting users lost funds, and the patch now checks input signatures before accepting such transactions. Bull Bitcoin is adding the same client-side check.
