Attackers using phishing email messages to attack Microsoft 365 consumers have been transforming to an old strategy in recent months — and the methodology is so stealthy that clients are “easy” to fall, victim, as per online security supplier Vade. The right-to-left override (RLO) strike has been around for over two decades.
It’s intended to deceive Microsoft 365 customers into clicking on a file affinity by masking the augmentation of the file. It is straightforward to fall into the trap if the user does not pay close attention to the outgrowth and does not consider the perspective of the email to evaluate if it is valid.
About Phishing
Phishing is still a prevalent and often devastating type of online attack. According to Proofpoint research results, 60% of organizations lose data as a result of an effective phishing scam, while 52% have their certifications or accounts compromised.
Meanwhile, well almost half of the organizations (47%), according to Proofpoint, become infected with malware as a consequence of a productive phishing campaign. In accordance with a Cloudian study, phishing emails account for 24% of all ransomware threats.
A Resurrected Strategy
Spear phishing a file’s expansions is plausible with the RLO strike method thanks to a special Unicode leading character as the right-to-left supersede. When used, the persona causes successive text to be displayed from right to left, the inverse of how English.
Previously, the strategy was used to conceal the “.exe” addition in a file, so that a subscriber who thought they were going to open a.txt file instead established malevolent executables, according to Vade. According to the email security supplier, the latest spate of RLO attacks has progressed to try to trick customers with a more modern type of file extension —.mp3 — that is presented as a voice message.

‘Notable’ Series Of Attacks
Over the last two weeks, Vade claims to have demonstrated over 400 different RLO obfuscation advertisements. Each advertisement is made up of a collection of emails with similar features, and a solitary advert can include hundreds or thousands of email messages to customers.
Thus, 400 distinct advertisements in two weeks “is a considerable number when you consider that one commercial can affect a large number of users in one or more businesses.” Because most security professionals aren’t sensing the RLO attachments as malevolent, businesses will have to rely on employees’ consciousness of the trick, as well as online fraud training, to decrease the likelihood of these attacks, he said.
