Business Email Account Compromise: The Growing Concern

April 4, 2022 0 Comments

In recent days, there have been instances of business email accounts being compromised, raising the need to address this critical issue. One notable incident involved phishing emails targeting Google accounts in the past. Though Google itself was not compromised, scammers used these phishing emails to deceive users into sharing their login credentials. Once obtained, the scammers set up forwarding rules, copying sensitive emails to another account.

The alarming aspect of such attacks is that even with some level of awareness and vigilance among users, all it takes is for one individual within the organization to fall victim to the phishing scam, compromising the entire security posture. Cybercriminals have become adept at crafting believable phishing messages, not just limited to emails but also exploiting social media and manipulating search engine rankings for malicious purposes. The most effective way to combat this is through comprehensive user education.

The motivation behind such attacks appears to be more than mere random cybercrime. Cyber espionage seems to be the primary motive, especially considering the targeted nature of the attacks and the high-value information and political implications involved. In recent years, there has been a shift from attacks aiming to disrupt or destroy services to information and identity theft. Malware and viruses have evolved to stealthily steal login credentials and sign machines up to botnets rather than causing immediate, visible harm.

So, what can companies like Google do to counter these threats? First and foremost, they can improve their SPAM filtering to better detect and block phishing emails. This alone would significantly reduce the scope of the problem. Additionally, user education is crucial, though it may not be foolproof against the most sophisticated social engineering tactics. Organizations and governments that deal with sensitive information should discourage using personal email accounts like Gmail for official business and promote strong security practices like using different passwords and maintaining vigilance.

Spear phishing, which targets specific users based on extensive background research, is more challenging to combat. Traditional measures like one-time passwords or tokens can be effective, but they may not be financially feasible for widespread implementation. Software token solutions may offer a cost-effective alternative, reducing the success rate of attacks. Nevertheless, it’s essential to address man-in-the-middle (MITM) attacks, which still pose a risk even with advanced security measures.

For individuals, spear phishing may not be a major concern, but without proper education, they can still fall victim to bulk phishing scams. However, for organizations and individuals with access to valuable information, spear phishing is a serious threat. The effectiveness of these attacks hinges on the skill and determination of the attacker. Entities dealing with sensitive data, such as HM Treasury, should be particularly cautious about such attacks.

In conclusion, business email account compromise is a growing concern that demands attention and proactive measures. A combination of robust security measures, user education, and advanced authentication techniques can help mitigate the risks and ensure a more secure digital environment.
