Malware infecting Androids somewhere in the supply chain

Handsets leave the factory clean, then get dragged through the mud before they reach you


Smartphones from Samsung, LG, Xiaomi, ZTE, Oppo, Vivo, Asus and Lenovo have been spotted sporting malware they apparently carried when they were shipped.

The malware discovered by Check Point Software Technologies included info-stealers, ransomware like Slocker; Loki, which shows “illegitimate advertisements” to generate revenue while stealing device information; and information stealers.

Check Point says it found infections in 38 Android devices. Since the malware wasn't in the vendor's ROM, the company's researcher Oren Koriat reckons they were added in the supply chain between vendor and customer.

Koriat's post doesn't identify the victims beyond saying two companies owned the devices: one large telecommunications company, and one international IT company.

The malicious package names and devices they were spotted on are listed below. Since they were added after manufacture, vendors aren't to blame.

“Six of the malware instances were added by a malicious actor to the device’s ROM using system privileges, meaning they couldn’t be removed by the user and the device had to be re-flashed”, Koriat writes. ®

  • To cut off all nearby phones with these Chinese chips, this is the bug to exploit
    Android patches incoming for NAS-ty memory overwrite flaw

    A critical flaw in the LTE firmware of the fourth-largest smartphone chip biz in the world could be exploited over the air to block people's communications and deny services.

    The vulnerability in the baseband – or radio modem – of UNISOC's chipset was found by folks at Check Point Research who were looking for ways the silicon could be used to remotely attack devices. It turns out the flaw doesn't just apply to lower-end smartphones but some smart TVs, too.

    Check Point found attackers could transmit a specially designed radio packet to a nearby device to crash the firmware, ending that equipment's cellular connectivity, at least, presumably until it's rebooted. This would be achieved by broadcasting non-access stratum (NAS) messages over the air that when picked up and processed by UNISOC's firmware would end in a heap memory overwrite.

  • Emotet malware gang re-emerges with Chrome-based credit card heistware
    Crimeware groups are re-inventing themselves

    The criminals behind the Emotet botnet – which rose to fame as a banking trojan before evolving into spamming and malware delivery – are now using it to target credit card information stored in the Chrome web browser.

    Once the data – including the user's name, the card's numbers and expiration information – is exfiltrated, the malware will send it to command-and-control (C2) servers that are different than the one that the card stealer module uses, according to researchers with cybersecurity vendor Proofpoint's Threat Insight team.

    The new card information module is the latest illustration of Emotet's Lazarus-like return. It's been more than a year since Europol and law enforcement from countries including the United States, the UK and Ukraine tore down the Emotet actors' infrastructure in January 2021 and – they hoped – put the malware threat to rest.

  • HelloXD ransomware bulked up with better encryption, nastier payload
    Russian-based group doubles the extortion by exfiltrating the corporate data before encrypting it.

    Windows and Linux systems are coming under attack by new variants of the HelloXD ransomware that includes stronger encryption, improved obfuscation and an additional payload that enables threat groups to modify compromised systems, exfiltrate files and execute commands.

    The new capabilities make the ransomware, first detected in November 2021 - and the developer behind it even more dangerous - according to researchers with Palo Alto Networks' Unit 42 threat intelligence group. Unit 42 said the HelloXD ransomware family is in its initial stages but it's working to track down the author.

    "While the ransomware functionality is nothing new, during our research, following the lines, we found out the ransomware is most likely developed by a threat actor named x4k," the researchers wrote in a blog post.

  • Now Windows Follina zero-day exploited to infect PCs with Qbot
    Data-stealing malware also paired with Black Basta ransomware gang

    Miscreants are reportedly exploiting the recently disclosed critical Windows Follina zero-day flaw to infect PCs with Qbot, thus aggressively expanding their reach.

    The bot's operators are also working with the Black Basta gang to spread ransomware in yet another partnership in the underground world of cyber-crime, it is claimed.

    This combination of Follina exploitation and its use to extort organizations makes the malware an even larger threat for enterprises. Qbot started off as a software nasty that raided people's online bank accounts, and evolved to snoop on user keystrokes and steal sensitive information from machines. It can also deliver other malware payloads, such as backdoors and ransomware, onto infected Windows systems, and forms a remote-controllable botnet.

  • Chinese-sponsored gang Gallium upgrades to sneaky PingPull RAT
    Broadens targets from telecoms to finance and government orgs

    The Gallium group, believed to be a Chinese state-sponsored team, is going on the warpath with an upgraded remote access trojan (RAT) that threat hunters say is difficult to detect.

    The deployment of this "PingPull" RAT comes as the gang is broadening the types of organizations in its sights from telecommunications companies to financial services firms and government entities across Asia, Southeast Asia, Europe and Africa, according to researchers with Palo Alto Networks' Unit 42 threat intelligence group.

    The backdoor, once in a compromised system, comes in three variants, each of which can communicate with the command-and-control (C2) system in one of three protocols: ICMP, HTTPS and raw TCP. All three PingPull variants have the same functionality, but each creates a custom string of code that it sends to the C2 server, which will use the unique string to identify the compromised system.

  • Symantec: More malware operators moving in to exploit Follina
    Meanwhile Microsoft still hasn't patched the fatal flaw

    While enterprises are still waiting for Microsoft to issue a fix for the critical "Follina" vulnerability in Windows, yet more malware operators are moving in to exploit it.

    Microsoft late last month acknowledged the remote code execution (RCE) vulnerability – tracked as CVE-2022-30190 – but has yet to deliver a patch for it. The company has outlined workarounds that can be used until a fix becomes available.

    In the meantime, reports of active exploits of the flaw continue to surface. Analysts with Proofpoint's Threat Insight team earlier this month tweeted about a phishing campaign, possibly aligned with a nation-state targeting US and European Union agencies, which uses Follina. The Proofpoint researchers said the malicious spam messages were sent to fewer than 10 Proofpoint product users.

  • EnemyBot malware adds enterprise flaws to exploit arsenal
    Fast-evolving botnet targets critical VMware, F5 BIG-IP bugs, we're told

    The botnet malware EnemyBot has added exploits to its arsenal, allowing it to infect and spread from enterprise-grade gear.

    What's worse, EnemyBot's core source code, minus its exploits, can be found on GitHub, so any miscreant can use the malware to start crafting their own outbreaks of this software nasty.

    The group behind EnemyBot is Keksec, a collection of experienced developers, also known as Nero and Freakout, that have been around since 2016 and have launched a number of Linux- and Windows-based bots capable of launching distributed denial-of-service (DDoS) attacks and possibly mining cryptocurrency. Securonix first wrote about EnemyBot in March.
