Cybersecurity is the dominant concern for Managed Service Providers (MSPs), overshadowing other competitive challenges in the market. A recent survey by Sophos highlighted that the top challenges for MSPs are keeping abreast of security technologies, hiring enough security analysts, and staying current with threat landscapes. The lack of in-house security expertise is seen as the biggest risk to MSPs and their clients, exacerbating the challenge of providing comprehensive cyber defenses. Most ransomware attacks are initiated by cybercriminals using stolen credentials, underscoring the dangers of credential theft and highlighting the need for robust monitoring and response capabilities. Smaller MSPs face significant hurdles in staffing their security operations centers effectively, especially for around-the-clock coverage which is crucial due to the timing of most cyber-attacks. Sophos recommends MSPs to partner with firms that offer extensive managed detection and response (MDR) services to mitigate the impact of the talent shortage in cybersecurity. Reports from IBM and CrowdStrike also indicate a significant rise in cyber attacks using legitimate credentials, confirming a shift in tactics from traditional methods like phishing.

A macOS implant of the LightSpy surveillance framework has been identified, previously known to target only Android and iOS devices. LightSpy gathers sensitive user data including files, screenshots, location, voice recordings, and payment information from mobile users in the Asia-Pacific region.

The Bombay Stock Exchange (BSE) has mandated full encryption for all communications between traders' applications and its trading engine, affecting messages via the Enhanced Trading Interface (ETI). Previously, most communications between the BSE and brokers were encrypted, but newly, price quote requests were mandated to be encrypted following a directive from India's Securities and Exchange Board. The encryption uses the AES 256 standard, with a transitional period where encrypted and non-encrypted channels operated concurrently until the complete switch to encrypted channels, originally set for May 13, 2024, now extended to June 8, 2024. BSE began testing the encrypted protocol on March 28, providing both encrypted and non-encrypted options before fully phasing out the non-encrypted option. Market participants already using encrypted channels were urged not to delay transitioning to the fully encrypted service to prevent any disruptions after the set deadline. Encryption ensures confidentiality of sensitive data like trading prices and guards against the manipulation of data transmitted. The necessity for full encryption was highlighted by potential market impacts, such as information leaking from unencrypted price quote messages indicating possible large trades. Some existing security measures included TLS encrypted payload connections for low-frequency sessions, highlighting a blend of security layers previously implemented by BSE.
