Three senior executives at security firms say Chinese hacking of US companies has slowed in recent months ahead of meeting between US and China presidents
Context & Ripple Effects
This report lands at the front end of a cycle the corpus keeps documenting: Chinese hacking of US targets quiets around high-stakes diplomacy, then returns. A FireEye analysis found a sharp drop-off in Chinese attacks on US companies in the two years after the 2015 period, and US officials later confirmed espionage was pared back under the 2015 US-China pact before picking up again in 2017 and accelerating. The executives' read — a slowdown ahead of a presidents' meeting — fits that same diplomatic-calendar rhythm rather than signaling a permanent retreat.
The stakes of reading these lulls correctly have grown since: after US agencies missed major Chinese and Russian intrusions, the White House pursued an overhaul of cyber defenses and new industry partnerships, and more recently Beijing has moved to strip out Western visibility entirely by ordering domestic firms to stop using cybersecurity software from roughly a dozen US and Israeli vendors.
First-order effects
- US companies targeted by Chinese intrusion teams get a measurable reprieve in attack volume in the months before the summit, though the executives' attribution rests on private telemetry, not any announced policy change from Beijing.
Second-order effects
- If the 2015-pact precedent holds, the lull is tactical: US officials already documented espionage resuming and accelerating within two years of the last diplomatic pause, so defenders who stand down risk being caught by the rebound.
Third-order effects
- Each side is degrading the other's ability to verify quiet periods — Washington has shelved tech-security measures ahead of leader meetings while Beijing bans Western security software outright — pushing US-China cyber competition toward an environment where slowdowns are harder to confirm and trust-building claims harder to audit.
The trend: Chinese cyber operations against US companies ebb and flow with the diplomatic calendar, while each government's capacity to independently verify the other's restraint keeps eroding.
