Tom is effective for a reputable money institution. He has a extended, advanced password that would be close to-unachievable to guess. He is memorized it by heart, so he started off applying it for his social media accounts and on his particular equipment much too. Unbeknownst to Tom, 1 of these web pages has had its password database compromised by hackers and place it up for sale on the dark web. Now threat actors are working hard to website link these leaked credentials again to genuine-daily life folks and their destinations of operate. Prior to long, a danger actor will use Tom’s legitimate email account to mail a spear-phishing link to his CEO.
This is a prevalent account takeover scenario where malicious attackers achieve unauthorized obtain to the organization’s units, putting critical facts and operations at risk. It usually starts off with compromised credentials. We are going to operate by why account takeover is so hard to end at the time it starts off and why potent password security is the most effective prevention.
Why are account takeover assaults so hazardous?
Getting entry to an Active Directory account within an organization is a desire circumstance for a hacker. They can launch social engineering assaults from a reputable related email account or quick messaging company, speaking with other workforce from a trustworthy account that is not going to be flagged by interior security. If the phishing messages are cautiously crafted, it could be some time right before the impersonation is uncovered.
Attackers could take about an account with current privileges or compromise a stale or inactive account and try to elevate their privileges from there. This can give them the keys to all method of sensitive facts shared inside the group, these types of as private business plans, fiscal info, mental property, or individually identifiable details (PII) of workforce or prospects. The legitimacy of the compromised account will increase the probabilities of results in these fraudulent pursuits.
Mainly because these assaults contain the use of respectable user qualifications it truly is tough to distinguish in between authorized and unauthorized accessibility. Attackers normally mimic the actions of legit users, creating it more challenging to detect suspicious actions or anomalies. Consumers may possibly not be conscious that their accounts have been compromised, especially if the attackers retain entry without increasing suspicion. This delay in detection lets attackers to go on their destructive pursuits, rising the potential damage and making remediation far more demanding.

Actual-daily life illustration: U.S. Point out Govt breach
A modern security incident in an unnamed U.S. State Federal government business highlighted the dangers of account takeover. A threat actor efficiently authenticated into an inside digital personal network (VPN) entry point applying an ex-employee’s leaked qualifications. Once inside the network, the attacker accessed a virtual device and blended in with authentic targeted visitors to evade detection. The compromised digital machine furnished the attacker with accessibility to yet another established of qualifications with administrative privileges to both the on-premises network and Azure Active Directory.
With these credentials, the threat actor explored the victim’s environment, executed light-weight directory accessibility protocol (LDAP) queries versus a area controller, and received entry to host and person information. The attackers then posted the breached facts on the dark web, intending to promote it for monetary gain.
How weak and compromised passwords direct to account takeover
Terrible password security techniques can appreciably improve the risk of account takeover. Utilizing weak passwords that are effortless to guess or crack tends to make it very very simple for attackers to compromise accounts. End customers decide on typical root phrases and then increase particular characters with easy structures to satisfy complexity demands like “password123!”. These will be fast guessed by automated brute power tactics applied by hackers.
A relating to number of organizations nonetheless have password procedures that make it possible for weak passwords which are huge open up to account takeover. Even so, it’s significant to remember solid passwords can become compromised much too.
Password reuse is often disregarded but is one particular of the riskiest conclude-user behaviors. When people today reuse the same password (even if it is a solid one particular) across many accounts, a breach in 1 assistance can expose their credentials, creating it a lot easier for attackers to attain entry to other accounts. If a cybercriminal obtains a user’s password from a compromised website, they can attempt applying it to gain unauthorized obtain to their operate accounts.
Bolster password security to avert account takeover
Stronger password security plays a essential position in avoiding account takeover attacks. Employing MFA adds an extra layer of security by necessitating users to deliver supplemental verification elements, these types of as a just one-time password, biometric facts, or a actual physical token, in addition to their password. Even so, MFA is just not infallible and can be bypassed. Weak and compromised passwords are even now virtually often the beginning place for account takeover.
Implementing advanced password prerequisites, this sort of as a minimum amount length of 15 characters, a blend of uppercase and lowercase letters, numbers, and specific people, would make it tougher for attackers to guess or crack passwords by means of brute-pressure or dictionary assaults.
Even so, your firm also requires a way to detect passwords that may possibly have turn into compromised by way of dangerous habits this sort of as password reuse. A instrument like Specops Password Policy constantly scans your Lively Listing natural environment versus an at any time-rising record of around 4 billion compromised passwords. If an conclusion person if found to be utilizing a breached password, they’re pressured to transform it and near off a probable attack takeover route.
