ACAMS CCAS Exam With Confidence Using Practice Dumps

Red flags related to anonymity include transactions where virtual assets are cashed out at exchanges from peer-to-peer hosted wallets with no clear business rationale. Such behavior indicates attempts to obscure the origin or destination of funds, characteristic of laundering activities.

Executing high-value transactions after inactivity (A) or frequent transfers to known VASPs (C) may be suspicious but are less directly linked to anonymity. Exchanging at a loss (D) is a different type of red flag.

FATF’s red flag indicators list (2021) highlights (B) as a key sign of anonymity-related risk.

Indirect exposure refers to a situation where cryptoassets are not directly associated with illicit activity but have transactional links through other addresses that are associated with risky or illicit behavior. Blockchain analytics tools detect these indirect links to flagged addresses, allowing firms to assess risk based on network connections rather than direct ownership or activity.

The DFSA AML guidance and international FATF Virtual Assets guidance explain that indirect exposure is a critical concept for transaction monitoring as it broadens the detection scope beyond direct transactions, flagging assets that might be “tainted” through intermediary addresses.

A 51% attack refers to a situation where a single miner or group controls more than 50% of the blockchain network’s computational (hashing) power. This majority control allows them to manipulate the blockchain ledger by double-spending or blocking transactions.

This term is widely recognized in blockchain security contexts and is referenced in typology papers on crypto financial crime risks, including those issued by UAE authorities and FATF.

Supporting extracts:

DFSA AML thematic reviews mention the risk of manipulation and double spending in blockchains susceptible to 51% attacks.

Typology reports on cryptoasset risks highlight computational power concentration as a core vulnerability.

“51% refers to the percentage of total mining power or computational power in the network” is the standard definition across crypto AML/CFT frameworks【31.92._TFS_Typology_Paper_Eng__4.pdf; AMLCFT_Guidance_for_FIs.pdf】.

Thus,Cis correct.
