Attack Tactics
The Black Basta-style attack employed several sophisticated techniques:
- Platform Impersonation: Attackers posed as popular platforms like WordPress and Shopify, using legitimate-looking domains to send fake account creation and subscription emails.
- Sneaky Domains: Messages originated from seemingly harmless domains like genomelink.io and mandrillapp.com, carefully chosen to evade simple filters.
- Character Obfuscation: Subject lines included unusual characters or minor variations to bypass basic keyword checks and confuse recipients.
- Varied Account Types: Emails referenced different user roles to increase the chances of catching someone’s attention.
- Psychological Triggers: Urgent phrases like “Your account has been created” were used to create a sense of panic and prompt hasty actions.
