Frae Social Engineering tae DDOS attacks, there are mony ways in which data can be lifted fae online companies. And fur companies big and wee, it's no jist their personal data that's at risk, but also their business data.
Improve your skills for Cyber Attacks:
--- PASSWORDS ---
Aye, mair than 50% o' database breaches are caused by using weak passwords or never changin' them. Honestly, I've seen mony small businesses use passwords just for the sake o' it; ye can easily create a professional phishing campaign, an eviltwin attack (live attacks involvin' proximity and the use o' antennas or network cards), a keylogger, etc. It's the easiest thing tae dae.
For big companies this ramps up a notch, ye must hae mair experience because use password managers like LastPass, KeePassXC, etc. plus they use lang passwords tae avoid a brute force attack and change them very often, so here ye must hone social engineering skills mair than onythin' else or the methods ye prefer, every attacker has their ace up their sleeve (or should hae).
--- VULNERATE 2FA ---
Two-factor authentication adds an extra layer o' security. Usually, companies enable this layer for their emails; but as always, naethin' is secure in this world, just look at the BlackBerry company or as I like tae ca' it, CrackBerry, onyway, tae breach 2FA ye hae tae learn how tae dae SMS relay attacks, spoof device identities, RATs, etc.
--- PERSONAL DEVICES ---
Personal smartphones can be a threat if they're connected tae the corporate network, this obviously doesnae apply in cyber security companies, here employees are obligated tae use only and exclusively the electronic devices provided tae them in the controlled and monitored corporate network tae avoid the use o' personal gear.
But, if we talk aboot common companies like clothing market for example or some gov, this isnae taken intae account and ye can compromise the company wi' contacts, customer information, bank accounts, passwords, etc. That's why it's guid tae be updated wi' sophisticated RATs tae fully access a personal device o' ony employee, or better yet, the bosses.
--- ANTI-VIRUS and ANTI-MALWARE ---
Like the previous point, mony big companies and IT companies will aye use anti-virus and anti-malware for their work teams; However this isnae always the case, there are businesses that use anti virus "Full Free Premium Lifetime" tae save a few pennies, but non-legitimate software is mair likely tae break wi' pirated antivirus, obfuscating payloads and hiding file cabinets. Whit has been successful for me at times, is tae mak' my ain "anti-malware full free forever", send it by email, and when they download the exe file, booommm babe, malware runnin' for the company.
--- WEB SITES ---
Ye should pay close attention tae the websites or applications o' companies, because sometimes ye can find common vulnerabilities in outdated operatin' systems or insecure plugins based on WordPress, so always thoroughly check every pairt o' the website or application tae exploit it and mak' yersel' the king of the company.
This is jist a quick guide o' whit aspects tae work on tae carry oot a successful cyberattack, however, keep in mind that this is no definitive, ye aye hae tae go beyond cybersecurity systems so it's also guid tae ken aboot ethical hackin' and advanced computer security courses; Some time later ye will be able tae hae yer ain digital weaponry and program yer ain viruses, malware, ransomware, rats, etc. Be yin step ahead o' the others (NEVER forget or underestimate yer anonymity, when ye dae cyber attacks, mony bastards set up honeypots and mair shites, so aye protect yer identity if ye dinnae want the feds tae enter through yer window and blow ur brain).
