Rewinding to the birth of the LightlessCan malware assault

Got a clue about malware?

Malware is simply a devilish abbreviation for malicious software. It’s a sort of devious digital tool that cyber bullies craft to muddle, mutilate or sneak into computer platforms, circuits, or gadgets without official consent. These goons are exploiting loopholes, filching confidential data, or puppeteering hi-jacked systems for their own wicked purposes.

Malware can masquerade in multitudinous forms like viruses, worms, Trojans, ransomware, spyware, adware, and rootkits. Each malware breed is unique in its way of spreading chaos and effectuating malevolent deeds.

Viruses are clones, self-disciplined and auto-duplicating that invade other files or programs by embedding their evil encrypted instructions. They can wreak havoc or infiltrate other platforms when the infected files are unwittingly passed on.

Worms hardy need a host and can multiply and propagate autonomously over networks, taking advantage of safety slips and carrying out destructive deeds by gobbling up system resources.

Trojans, baptized from the noted Trojan horse tale of ancient Greece, pose as innocuous or bonafide programs but are, in reality, bearers of destructive codes. They trick victims into triggering them, subsequently opening up the infected systems to unsanctioned entry or enabling other malevolent operations.

Ransomware kidnaps your files or barricades your access to your own systems, demanding a bounty for reinstating access or decoding the captive files.

Spyware is a secret agent program that infiltrates to collect information about a user or system under the radar and without permission. It can monitor internet surfing patterns, record your key strokes, filch personal data, or offer a hidden back door to the infiltrator.

Adware invades your device to annoyingly display undesired ads, most times incessantly or vexatiously, consequently making moola for the adware manufacturer.

Rootkits are akin to master keys used to encroach unpermitted high-level accessibility to a computer or a network. They’re experts at disguising their existence and maintaining non-stop unauthorized access, making them a nightmare to identify and terminate.

Malware can infiltrate your system via numerous avenues like deceptive downloads, infected emails, malicious websites, transferable drives, or untrustworthy software. Safeguarding against these virtual threats is key, and it starts with ensuring your antivirus and security software is current. Couple this with consistently updating your OS and apps, being mindful of dodgy attachments in your mail, avoiding suspicious internet sites, and instilling responsible online surfing practices.

How would you describe the LightlessCan malware threat?

A recently unveiled malware, LightlessCan, made its sinister debut via the notorious North Korean hacking collective “Lazarus,” who used it to mount a cyber intrusion against a Spanish aerospace firm. Deceptively distributed via fabricated job offerings on LinkedIn, this malware hides in plain sight. Once embedded in a business’s network, it releases its payload, a remote control Trojan horse that is capable of executing 43 out of its 68 commands. LightlessCan surreptitiously apes a wide range of ordinary Windows functionalities, permitting an unobtrusive execution within the RAT, bypassing any noticeable console executions.

Rewinding to the birth of the LightlessCan malware assault.

The curtains on LightlessCan were lifted in September 2023. The master puppeteer was the infamous North Korean hacker group, Lazarus, who set their malevolent sights on a Spanish aerospace corporation. Wearing the mask of job recruiters on LinkedIn, they offered fraudulent job proposals to penetrate the company’s defenses. The unsuspecting target would be sent two seemingly harmless coding challenges, part of the deceiving recruitment process, only to be drawn into a multi-staged trap that would unleash the notorious malware.

One of LightlessCan’s most remarkable abilities is its uncanny imitation of standard Windows commands, a stealthy disguise that grants it safe harbour within the RAT, escaping standard detection. This backdoor – capable of executing numerous orders, with 43 of the possible 68 tasks already operational – is a formidable adversary. It was the keen-eyed researchers at ESET who first discovered LightlessCan and gave it its befitting name.

The success of the cyber onslaught on the Spanish aerospace corporation was a grim testament to the evolving sophistication of the Lazarus group. Their playbook, incorporating cunning social engineering moves and the deployment of an unheard-of backdoor, underscored their rising prowess and audacity.

What if LightlessCan malware has preyed upon you?

Staying on your toes and handling malware encounters proactively is fundamental. Embrace these steps to lessen the damage caused by LightlessCan malware and shield your system and personal data.

Safeguarding Against LightlessCan Malware Intrusion

Listed below are a succession of protective measures to guard against LightlessCan malware attacks:

1.    Refresh your software consistently: Vigilance in maintaining the latest software versions on your devices, including operating systems and web browsers, shields you from potential weak spots that malware like LightlessCan may exploit.

2.    Depend on trustworthy antivirus software: Setting up a reliable antivirus or anti-malware defense platform that stays current with updates, helps detect and cleanse your system of familiar malware strains like LightlessCan and defend against emerging threats in real time.

3.    Be cautious with email attachments and web links: Exercise care when handling email attachments or web links from unidentified or dubious origins. Past incidents of LightlessCan malware infection have occurred through manipulated links and phishing scam emails.

4.    Watch out for social engineering tactics: Incidents have been reported where LightlessCan malware was spread through the impersonation of job recruiters on platforms like LinkedIn. Be circumspect while conversing with unfamiliar contacts or responding to uninvited job offers or recruitment correspondences.

5.    Advance your security with Multi-factor Authentication (MFA): Enhancing your online profiles with MFA secures you with an extra defense layer, making unauthorized entry attempts by hackers even more challenging.

6.    Routinely back up your data: Establish a regular backup cycle of essential files and data. If a malware attack occurs, your backup versions will enable recovery of your files without needing to pay a ransom or risk losing invaluable data.


In conclusion, your best defense against malware attacks like LightlessCan is to remain alert and maintain a strong cybersecurity routine.

To boil it down, LightlessCan is an advanced malware employed by the notorious Lazarus hacking squad to prey on certain entities, including a Spanish aerospace firm. The malware voyaged through intricate social engineering maneuvers, with the hackers masquerading as job scouters on platforms like LinkedIn. An intriguing element of LightlessCan is its ability to emulate native Windows commands, assisting it to infiltrate undetected into the target’s system.

If there’s a suspicion that LightlessCan malware has infiltrated your system, your response should be swift and decisive.
