Analysis of cyber attacks such as APT (Advanced Persistent Threat) and ransomware
In the information society, cyber attacks launched upon the information technology infrastructure are increasingly diversified and complex. Cybercriminals or black hat hackers use a wide range of techniques, tactics and procedures to compromise computer systems. APT and ransomware attacks are two cyber security threats that many companies and government institutions face. Ransomware is a medium complexity attack, while APT is a high complexity cyber attack. The emergence of certain hybrid malicious programs (computer worm-ransomware) and the diversification of attack vectors represent new challenges for specialists and organizations.

În cadrul acestui articol voi evidenția un modus operandi al hackerilor care lansează atacuri cibernetice de tip Denial of Service (DoS). Voi arăta teoretic cum pot fi realizate atacurile CAM Overflow și TCP SYN Flood, utilizând Kali Linux, o distribuție de Linux utilizată de criminalii cibernetici pentru a putea lansa atacuri de tip MitM (Man-in-the-Middle), atacuri DoS, observarea traficului dintr-o rețea de calculatoare etc. Hackerii pot afecta funcționarea dispozitivelor din rețeaua locală a unei organizații (server, router, switch etc.) prin trimiterea a mii de pachete/secundă către dispozitivul țintă. CAM Overflow este un atac prin care un hacker urmărește să supra-aglomereze tabela CAM a unui switch cu adrese MAC, iar TCP SYN Flood este un atac care poate fi lansat împotriva unui server din rețeaua de calculatoare.
