As soon as entry is granted, UNC6040 pulls information in levels. Generally, they begin small to keep away from detection, utilizing check queries and restricted batch sizes. If the preliminary probing goes unnoticed, they scale up the operation and start large-volume exfiltration.
Extortion Comes Later

Throughout these messages, attackers claimed to be related to the well-known hacking group ShinyHunters, a transfer probably geared toward rising strain on victims to pay up.
This delayed method hints that UNC6040 could be working with different actors who concentrate on monetizing stolen information. Whether or not they’re promoting entry or handing off the info for follow-up assaults, the lengthy pause makes incident detection and response extra sophisticated for safety groups.
Whereas the first goal is Salesforce, the group’s ambitions don’t finish there. As soon as they achieve credentials, UNC6040 has been noticed shifting laterally via company techniques, concentrating on platforms like Okta and Microsoft 365. This broader entry permits them to gather further priceless information, deepen their presence, and construct leverage for future extortion makes an attempt.
Defending Towards These Assaults
GTIG advises taking just a few clear steps to make a lot of these breaches much less probably. First, restrict who has entry to highly effective instruments like Information Loader, solely customers who genuinely want it ought to have permissions, and people ought to be reviewed commonly. It’s additionally vital to handle which related apps can entry your Salesforce setup; any new app ought to undergo a proper approval course of.
To forestall unauthorized entry, particularly from attackers utilizing VPNs, logins and app authorizations ought to be restricted to trusted IP ranges. Monitoring is one other key piece, platforms like Salesforce Defend can flag and react to large-scale information exports in actual time. Whereas multi-factor authentication (MFA) isn’t good, it nonetheless performs a significant position in defending accounts, particularly when customers are skilled to identify methods like phishing calls that attempt to get round it.
