Researchers have discovered a new malware distribution campaign that utilizes malicious macros concealed in Microsoft PowerPoint attachments.

According to security agency Trustwave, the rigged PowerPoint data files are getting dispersed en masse by using e mail and, at the time downloaded, established in movement a chain of occasions that in the end guide to a LokiBot malware an infection.

This mechanism in alone is not abnormal, but the way in which this individual scam evades detection caught the company’s eye. Namely, the way URLs are manipulated to conceal the ultimate payload.

PowerPoint malware campaign

According to Trustwave, the series of domains employed in this campaign to infect the concentrate on consumer had been truly by now known to host malicious information.

However, the hackers have leveraged URL manipulation procedures to conceal the unsafe domains, hoodwinking each the victim and any security filters that may well be in position.

Especially, the campaign abuses standard uniform resource identifier (URI) syntax to bamboozle antivirus companies coded to guard against only URLs that stick to a individual structure.

Opening and closing the contaminated PowerPoint file activates the malicious macro, launching a URL by using the Home windows binary “mshta.exe.”, which alone redirects to a VBScript hosted on Pastebin, an on the internet company for storing plain text.

A single loads up a DLL injector, which is then employed to infect the machine with a sample of LokiBot malware concealed in the ultimate URL.

This method may well appear excessively convoluted, but the levels of concealment and misdirection – coupled with URL-associated sleight of hand – are what enables the attack to proceed unchecked.

To mitigate against this type of danger, Trustwave has recommended people to set in position a subtle anti-malware alternative intended exclusively to combat e mail-centered threats and to interrogate all URLs for irregularities that may well betray a scam.

TechRadar Professional has sought more clarification as to what people can do to discover unsafe URLs that have been manipulated as explained previously mentioned.
