Cybercriminals Hide Malware Commands in Malicious Memes
Trend Micro security researchers have discovered a new piece of malware that receives commands via malicious memes its operators published on Twitter.
The method used to conceal malicious commands is called steganographyand has long been abused by cybercriminals to hide malicious payloads inside files in order to evade security solutions. Several years ago, security researchers observed the technique being abused in exploit kitand malvertising campaigns.
The use of social media platforms such as Twitter to send commands to malware isn't new either. Malware that abuses such services has been aroundfor several years.
As part of the newly analyzedattack, the actor published two memes (images that are humorous in nature) containing malicious commands on their Twitter account. The memes were published in late October, but the account had been created last year.
The embedded command is parsed by the malware after the malicious meme is downloaded onto the victim's machine. Detected as TROJAN.MSIL.BERBOMTHUM.AA, the malware itself wasn't downloaded from Twitter, but managed to infect the victim's machine via an unknown mechanism.
The memes contained the "/print" command, which instructs the malware to take screenshots of the infected machine's desktop. The malware then sends the screenshots to a command and control (C&C) server address that it had obtained through a hard-coded URL on pastebin.com.
Once executed on an infected machine, the malware can download memes to extract and then execute the commands embedded inside. The URL address used in the attack is an internal or private IP address, which the security researchers believe is a temporary placeholder used by the attackers.
Based on the commands received via Twitter, the malware could capture the screen, retrieve a list of running processes, capture clipboard content, retrieve the username from infected machine, or retrieve filenames from a predefined path (such as desktop, %AppData% etc.), the security researchers reveal.
Twitter has already suspended the account used in these attacks.
"Users and businesses can consider adopting security solutions that can protect systems from various threats, such as malware that communicate with benign-looking images, through a cross-generational blend of threat defense techniques," Trend Micro concludes.

After six summers of researching, testing, and recommending window air conditioners, we've learned that quiet and affordable ACs make most people the happiest—and we think the LG LW8016ER will fit the bill in most rooms. This 8,000 Btu unit cools as efficiently and effectively as any model with an equal Btu rating, and runs at a lower volume and deeper pitch than others at this price. Little extra features like a fresh-air vent, two-axis fan blades, and a removable drain plug help set it apart, too. The LG LW8016ER is a top choice for an office or den, and some people will find it quiet enough for a bedroom, too. If our main pic
Pre-loaded cartridges of cannabis concentrate are currently among the most popular means of consumption, and for good reason. They're discreet to use and easy to handle, a far cry from the dark days of 2016 when we had to dribble hash oil or load wax into narrow-mouthed vape pens by hand. But, frustratingly, an ever increasing number of oil cartridge manufacturers employ one-off design standards so that their products won't work with those of their competitors, thereby locking customers into proprietary ecosystems. We've already seen this with nicotine vaporizers -- which has a seen a massive rise in "pod systems" in the last few years, each outfitted with a unique canister and battery built to be incompatible with those of their competition. Is it too late for the burgeoning cannabis industry to set a universal standard for their product designs?
