Sometimes ordinary politeness is too expensive for business.
CrowdStrike warns a noticeable shift in the tactics of extortion groups: attackers are increasingly bypassing classic means of protection not through contamination of workstations, but through trusted cloud services. In such attacks, hacking may look like the usual entry of an employee into a corporate account, and data theft begins in a matter of minutes.
According to CrowdStrike, since October 2025, CORDIAL SPIDER and SNARCY SPIDER have been launching quick attacks on SaaS environments using voice phishing. Attackers pretend to be employees of IT support and convince employees to switch to fake single-entered pages. The domains of such sites simulate corporate portals, so the victim sees the usual form of authorization and does not notice the trick.
After entering the accounting data, the attackers intercept not only the login and password, but also active session tokens. This approach allows them to access the single-entered system and related SaaS applications without a separate hack of each service.
To fix in the compromised CORDIAL SPIDER and SNARKY SPIDER accounts, multi-factor authentication devices are added. In some cases, the old MFA devices were removed before registering new ones. CrowdStrike notes that SNARKY SPIDER almost always used the Genemobile Android emulator, and CORDIAL SPIDER used a wider set of mobile devices and QEMU.
Then the attackers try to hide the traces of hacking. SNARKY SPIDER, according to CrowdStrike observations, removes letters with notifications of suspicious activity and creates mailbox rules that automatically remove messages with words like “alert”, “incident” and “MFA”. So the victim may not see warnings about a new device or strange input.
After confusing, the groups look for documents and messages in SaaS platforms by sensitive words, including “confidential”, “SSN”, “contracts” and “VP”. Such a search helps to quickly find contracts, internal materials, employee data and information about the infrastructure.
The main goal of both groups is the mass unloading of data from SharePoint, HubSpot, Google Workspace and other cloud services. CrowdStrike emphasizes that the attacks are not related to the vulnerabilities of the SaaS platforms themselves. Problems are more likely to arise from weak settings in customers, lack of friction-resistant MFA and too wide access rights.
Commercial VPNs and resident proxies, including Mullvad, Oxylabs, NetNut, 9Proxy, 9Proxy, Infatica and NSOCKS are used to disguise CORDIAL SPIDER and SNARKY SPIDER. Resident proxies are particularly difficult to detect attacks, as traffic looks like connecting from home IP addresses of ordinary users.
CrowdStrike links such campaigns to an increasing gap between end-bossing and visibility inside SaaS environments. Even a well-protected workstation will not help if the attacker has already entered the cloud services through a stolen session and acts on behalf of a real user.
