Infostealers continued to develop in recognition on the cybercrime underground final 12 months, with credentials from password shops showing in 29% of malware samples analyzed by Picus Safety.
The safety vendor’s Pink Report 2025 examined over a million malware samples and mapped greater than 14 million malicious actions and 11 million situations of MITRE ATT&CK strategies, so as to raised illuminate the menace panorama.
It revealed a three-fold enhance within the share of malware strains concentrating on credential shops – reflecting the rising marketplace for compromised logins.
“A rising pattern in credential theft targets password managers, browser-stored credentials, and cached login knowledge to achieve lateral motion and afford attackers elevated privileges to delicate methods,” the report famous. “These stolen credentials are later used for lateral motion and privilege escalation, permitting attackers to broaden their attain inside the environments they’ve compromised.”

Credentials stolen by way of infostealers have been used within the Snowflake marketing campaign final 12 months which resulted within the compromise of a whole bunch of thousands and thousands of victims.
Among the many different developments Picus Safety revealed are:
- Strategies for stealth and evasion: Course of injection was noticed in 31% of analyzed samples. Code injected right into a reputable course of evades detection in lots of safety options, Picus Safety claimed. It additionally recorded the “Command and Scripting Interpreter” method, which allows attackers to make use of hard-to-detect native instruments, corresponding to PowerShell and Bash. Risk actors are additionally extra possible to make use of encrypted channels like HTTPS and DNS over HTTPS (DoH) for exfiltration or command-and-control (C2) communication, bypassing monitoring instruments.
- Actual-time knowledge theft: Attackers used “Enter Seize” and “System Data Discovery” to speed up knowledge theft in real-time. For instance, infostealers used keyloggers, display seize utility and audio interceptors.
- Persistence: “Boot or Logon Autostart Execution” is an more and more well-liked methodology for malware to outlive system reboots and elimination makes an attempt.
- Sophistication: A typical piece of malware now performs a median of 14 malicious actions and 12 ATT&CK strategies per pattern, indicating the rising maturity of the market and supporting “multi-stage, structurally advanced” assaults.
“Risk actors are leveraging subtle extraction strategies, together with reminiscence scraping, registry harvesting and compromising native and cloud-based password shops, to acquire credentials that give attackers the keys to the dominion,” mentioned Picus Safety co-founder and VP of Picus Labs, Suleyman Ozarslan.
“It’s very important that password managers are utilized in tandem with multi-factor authentication, and that workers by no means reuse a password, particularly for his or her password supervisor.”
“Attackers’ means to tailor their techniques to their environment speaks to a transfer towards precision-centric campaigns that work to create most destruction with minimal publicity,” the report famous.
