Credential spray attack detection
Cybersecurity is enhanced to detect credential spray attacks. Accounts with access failure events are divided into buckets B1 . . . BN based on access failure count ranges R1 . . . RN.

EN, which are compared to thresholds T1 . . . TN. An intrusion detection tool generates an alert when some Ei hits its Ti. Detection may spot any credential sprays, not merely password sprays. False positives may be reduced by excluding items from consideration, such as logon attempts using old passwords. False positives and false negatives may be balanced by tuning threshold parameters. Breached accounts may be found. Detection may also permit other responses, such as attack disruption, harm mitigation, and attacker identification.

The first packet is encapsulated with an outer header. The first host analyzes a length of at least a portion of the outer header in determining a size of an encrypted segment of the payload. Then, the first host forms a plurality of packets where each packet in the packets includes an encrypted segment of the payload, a respective encryption header, and a respective authentication value. The payload of the first packet is segmented to form a plurality of encrypted segments based on the size. The first host sends the packets to the second host and receives an indication that a packet was not received. A second packet including the encrypted segment is sent to the second compute node. |

Radiofrequency carrier tracking for amplitude-modulated signals with an unstable reference clock
Techniques are described for accurate tracking of a radiofrequency (RF) carrier for amplitude-modulated signals in unstable reference clock environments. For example, some embodiments operate in context of clock circuits in devices configured for near-field communication (NFC) card emulation (CE) mode. The clock circuits seek to generate an internal clocking signal by tracking a clock reference, such as an RF carrier. In some cases, the clock reference can unpredictably become unreliable for periods of time, during which continued tracking of the unreliable clock reference can yield appreciable frequency and phase errors in the generated internal clocking signal. Embodiments implement phase delta detection with time limiting to limit the magnitude of such errors in the internal clocking signal introduced while tracking an unreliable clock reference. For example, embodiments force gating of phase tracking signals to limit their duration, thereby limiting impacts of those phase tracking signals on the clock circuit output. |
