Spyware/APT named literacy. $MAL_LAB only. Original Cyberlium.

Spyware steals secrets; APT groups operate long campaigns — analysts name behaviors for hunting, not replication.

Spyware covertly collects keystrokes, screenshots, credentials, or audio. Advanced Persistent Threat (APT) actors combine stealth, custom tooling, and long dwell time against high-value targets — mapped in ATT&CK groups and vendor reports. Defenders hunt persistence, unusual egress, and credential access chains. Cyberlium teaches naming and report literacy for $MAL_LAB notes. You will NOT build spyware, keyloggers for strangers, or replicate APT campaigns against unauthorized targets. Next: Families Lab.

1. Spyware: covert collection

Spyware indicators: hooking APIs, unexpected microphone/camera access, browser credential dumps, exfil to rare domains. Consumer 'stalkerware' and enterprise infostealers share collection goals — defenders block exfil and remove persistence.

Analysis on $MAL_LAB labels collection modules in static strings or dynamic procmon — never deploy against real users.

Command guide

Try these commands — Spyware: covert collection

═══ LINUX / macOS (Malware Static & Dynamic Triage) ═══

Inspect PE / ELF binary headers and sections

Command — copy this

readelf -h sample.bin 2>/dev/null || xxd -g 1 -l 32 sample.bin

Check binary entropy (high entropy often signals packed or encrypted payloads)

Command — copy this

python3 -c "
import math, sys
data = open('sample.bin', 'rb').read() if len(sys.argv) > 1 else b'MZX\x00\x90'
ent = -sum((data.count(bytes([b]))/len(data))*math.log2(data.count(bytes([b]))/len(data)) for b in set(data))
print(f'Calculated File Entropy: {ent:.4f} (Entropy > 7.0 suggests packed/encrypted)')
" sample.bin 2>/dev/null

Primary tools to practice this lesson: curl, jq. Reference sites: CISA ransomware guide (https://www.cisa.gov/stopransomware/ransomware-guide); MalwareBazaar tags (https://bazaar.abuse.ch/browse/). Run every command in the box — install first, then the usage lines — only on YOUR lab / program scope.

2. APT: named groups and TTP chains

APT reports name groups (e.g., ATT&CK Gxxxx) with TTP sequences — spearphish, custom malware, lateral movement, data staging. Literacy means reading reports for detection gaps, not copying campaigns against classmates or employers without engagement.

Map report TTPs to YOUR $MAL_LAB detection wishlist — technique ID, log source, gap Y/N.

3. Named for hunt — not for harm

Forbidden: keylogger deployment, stalkerware, APT playbooks against production, or 'long dwell' on unauthorized networks. Allowed: family/spyware/APT vocabulary in analysis reports with IOC hygiene.

Ship: spyware vs APT one-liner + three ATT&CK technique IDs you'd hunt on $MAL_LAB SIEM fixture. Next: Families Lab.

4. What you ship: spyware/APT literacy note for $MAL_LAB

Spyware vs APT definitions. Three hunt technique IDs. NEVER keyloggers/stalkerware. chmod 600.

5. What you record before the next lesson

Date. Spyware/APT note. Three technique IDs. File t22-m02-l03-spyware-apt-named.txt chmod 600.

6. Wrong vs right: live malware on daily driver vs sandbox

Worked failure — same MSF word, opposite target. Right never needs a café Wi-Fi or classmate laptop.

Wrong: Deploy keylogger on classmate 'for APT lab.' Copy full APT chain to production.
Right: Write spyware/APT literacy note with hunt IDs. Next: Families Lab.
