Lumma and Snake Dominate Malware Uploads:
According to ANY.RUN’s Trends Tracker, Lumma had 644 uploads, which is 14 more than last week’s 630.
Lumma is an information stealer written in C that targets cryptocurrency wallets, login credentials, and other sensitive data.
Lumma operates as malware-as-a-service and is easily found on Dark Web forums and Telegram channels, posing a constant threat to Windows 7 through Windows 11 systems. Its wide compatibility and subscription model have made it popular among cybercriminals.
Snake experienced a significant increase of 262 uploads, jumping from 251 to 513. This sophisticated malware, often linked to the Russian Federal Security Service (FSB), employs advanced encryption methods like HTTP2 or TCP at the session layer, further encrypting each command exchange for stealth.
CISA’s recent Cybersecurity Advisory revealed a new Snake variant with a complex architecture and network communications, making it difficult to detect and address.
Other Notable Threats:
The ANY.RUN report also identified other prominent malware families in the top 10:
Xworm recorded 341 uploads, an increase of 36 from 305. AgentTesla surged by 210 uploads, rising from 116 to 326. AsyncRAT grew by 138 uploads, reaching 303 from 165. Remcos increased by 76, totaling 203 from 127. Sality and Dcrat also improved, with 151 uploads (up 53) and 132 uploads (up 60), respectively.
Not all malware increased; Tofsee dropped sharply from 529 uploads to 194, a decline of 335. Amadey also decreased by 51, falling from 146 to 95 uploads.
