PandaStealer is sent in rigged Excel information masquerading as company offers, bent on thieving victims’ cryptocurrency and other data.
Still an additional new facts stealer – Panda Stealer – is remaining spread by means of a all over the world spam campaign.
On Tuesday, Trend Micro researchers claimed that they first spotted the new stealer in April. The most current wave of the spam campaign has experienced the greatest effect in Australia, Germany, Japan and the U.S.

The spam email messages are masquerading as organization-estimate requests to entice victims into clicking on booby-trapped Excel documents. The researchers identified 264 files comparable to Panda Stealer on VirusTotal, with some of them currently being shared by risk actors on Discord.
That’s not surprising, specified latest tendencies: Cisco’s Talos cybersecurity staff a short while ago observed that danger actors have infiltrated workflow and collaboration instruments like Slack and Discord to slip earlier security and supply details-stealers, remote-access trojans (RATs) and other malware.
… Or Perhaps Collaborating on A lot more of the Exact
Then once again, danger actors could also be working with Discord to share the Panda Stealer build with each individual other, Craze Micro instructed.
When Panda gets cozy, it tries to hoover up aspects this sort of as non-public keys and earlier transactions from cryptocurrency wallets, like Bytecoin (BCN), Dash (Dash), Ethereum (ETH) and Litecoin (LTC). Further than thieving wallets, it can also filch qualifications from apps, which includes NordVPN, Telegram, Discord and Steam. Panda can also take screenshots of the infected laptop or computer and swipe data from browsers, together with cookies and passwords.
The researchers identified two approaches that the spam infects victims: In a single infection chain, an .XLSM attachment contains macros that down load a loader, which executes the primary stealer. In one more an infection chain, an .XLS attachment made up of an Excel method triggers a PowerShell command to obtain paste.ee, a Pastebin option that in transform accesses a 2nd encrypted PowerShell command. The picture under displays an Excel components accessing a paste.ee URL by using PowerShell command:

Panda Stealer is a tweak of the malware Collector Stealer, also regarded as DC Stealer, which has been found marketing on an underground forum and via Telegram for as little as $12. It’s advertised as a “top-close facts stealer” and has a Russian interface.
A danger actor referred to as NCP, also acknowledged as su1c1de, has actually cracked Collector Stealer. The cracked stealer and Panda Stealer behave equally, but they do not share the identical command-and-command (C2) URLs, make tags or execution folders. But the two exfiltrate information like cookies, login info and web knowledge from a compromised computer system, storing them in an SQLite3 database.
The cracked Collector Stealer is freely offered on the net, this means that it is quick to get it, tweak it and let it rip.
“Cybercriminal groups and script kiddies alike can use it to build their individual custom-made edition of the stealer and C2 panel,” Pattern Micro scientists reported. “Threat actors may also augment their malware campaigns with unique functions from Collector Stealer.
Fileless Distribution Covers the Scent
In addition to cribbing from Collector Stealer, Panda Stealer has borrowed from a further piece of malware: Specifically, it utilizes the same fileless distribution strategy as the “Fair” variant of Phobos ransomware to slip previous detection. In other words and phrases, it runs in memory just after preliminary infection, alternatively of storing information on the hard generate.
Dimiter Andonov, senior principal reverse engineer for Mandiant, explained to Threatpost in an email on Tuesday that the use of the fileless system is a hallmark of sophisticated malware procedures.
Panda drops files in focused systems’ Temp folders, storing stolen info less than randomized file names. Then, it exfiltrates the stolen knowledge and sends it to a C2 server. When analyzing that C2 server, researchers ended up led to a login page for “熊猫Stealer,” which interprets to “Panda Stealer,” while they identified far more domains that share that exact same login web page. The picture down below exhibits other login web pages identified as “熊猫Stealer:”
Scientists identified 14 victims detailed on the logs for a person of all those servers. They also found an IP deal with that they think the menace actor was using: It was hosted on a virtual non-public server (VPS) rented from Shock Hosting that had been compromised for testing purposes. Soon after scientists described their uncover to Shock Hosting, it suspended the server.
