DDoS Attacks Cause Major Threema Outages

Sustained distributed denial-of-service attacks knocked Swiss secure messenger Threema offline for hours before upstream filtering restored service; On-Prem users unaffected.

Threema suffered a series of large-scale DDoS attacks that left its Swiss secure messaging service unavailable for about four hours Tuesday evening, with intermittent outages into Wednesday morning until restoration at 12:23 p.m. CEST. Attacks also targeted colocation partner Nine and kept changing patterns, complicating mitigation. Threema deployed additional upstream DDoS protection on August 14 and plans status page improvements; Threema On-Prem customers running their own infrastructure were unaffected.

Risky Bulletin: Slovakia finds Russian backdoor in traffic speed cameras

Slovakia's NBU found an SMS-triggered backdoor in Russian-made NERO R-ONE traffic cameras, pausing a 279-unit deployment.

Slovakia's national security service NBU issued an alert against NERO R-ONE high-speed traffic cameras after finding a backdoor that grants shell and network access via SMS from hardcoded Russian phone numbers. The cameras are a rebranded version of the Russian CORDON PRO.M model by St. Petersburg firm Semicon, purchased via a Cyprus shell company under a €30 million EU-funded project. The report also found SecureBoot disabled, vulnerable web management, and unauthenticated live streams; the Interior Ministry paused deployment of 279 cameras pending independent assessment.

Chinese and Russian spies stepping up cyberattacks, German companies report

Bitkom survey finds nearly 40% of attacked German companies attribute incidents to foreign intelligence services, mainly China and Russia, costing up to $240B.

A Bitkom survey of 1,003 German companies with at least 10 employees found nearly four in 10 firms hit by data theft, espionage, or sabotage attributed at least one incident to a foreign intelligence service, up from 28% last year and 7% in 2023. China was the most cited source, named by more than half of affected companies, followed by Russia and Iran at roughly one in ten. Bitkom estimated cyberattacks cost German businesses $186-240 billion over the past year, with ransomware the most common attack type, affecting one in four companies. Recent incidents cited include breaches at Lidl, billing provider Unimed, and the Dresden State Art Collections.
