It’s been a whirlwind of a yr, with the very worst of COVID-19 sandwiching Fb’s annual PR disaster and a litany of cyber safety tales from the deep. Certainly, safety groups are nonetheless scrambling day by day to wrestle with the variety of threats dealing with companies, whereas ransomware gangs proceed to ransack their manner throughout the globe.
The likes of REvil and Emotet have terrorised companies, whereas additionally sporadically and unexpectedly shutting down amid mounting strain from regulation enforcement. From crippling assaults on important nationwide infrastructure to the persistent exploitation of zero-day vulnerabilities, most just lately within the type of the Log4Shell vulnerability, we spherical up probably the most surprising cyber safety scandals of the previous 12 months.
Microsoft Trade below siege
It’s been a torrid time for Microsoft Trade this yr, with zero-day exploits and vulnerabilities rising from each nook.
The issues started in March, when Microsoft introduced it’d found what it believed to be the Chinese language hacking group, Hafnium, executing a sophisticated attack using a chain of four previously undisclosed zero-day flaws focusing on on-premise Trade servers. Hafnium gained entry utilizing these vulnerabilities and stolen passwords, earlier than creating an online shell across the compromised servers. This allowed them to exfiltrate e mail knowledge remotely.
It’s estimated a complete of 30,000 servers have been compromised internationally, together with 7,000 within the UK. Patches have been quickly launched for giant organisations earlier than a one-click patch was issued for smaller companies with out devoted IT groups.
Sadly, this was shortly adopted by a collection of further zero-days, together with three the NSA disclosed in April, earlier than ProxyToken was unleashed in August. This flaw, once more
rapidly patched, may have been abused to steal private data and carry out configuration actions on track mailboxes. Zero Day Initiative consultants stated, on the time, this might have allowed a hacker to collect and exfiltrate all e mail addresses in an individual’s inbox, which might then be harnessed in phishing campaigns. The ProxyLogon exploit was subsequently on the centre of assorted assaults, with Epsilon Pink targeted servers in June. No less than ten teams have since abused the Hafnium exploit chain, with Qakbot and SquirrelWaffle malspam most just lately spreading via unpatched servers.
Fb’s first main snafu of the yr
Fb, as soon as extra, endured a crisis-laden yr, with a humongous knowledge scandal setting the tone for a rocky few months that finally led to the damaging revelations detailed by whistleblower Frances Haugen.
On 3 April, someone uploaded a database containing the private data of 533 million customers to a publicly accessible common deep net hacking discussion board. This represented a fifth of Fb’s consumer base, primarily primarily based within the UK, US, and India. The leak included telephone numbers, full names, earlier places, delivery dates, relationship statuses, biographies, and, in some circumstances, e mail addresses. Specialists, on the time, stated the data would seemingly be used for social engineering campaigns, hacking, and advertising functions.
Fb initially explained the hackers scraped knowledge from its servers by exploiting a misconfiguration in its contact importer. This, nevertheless, was truly a part of a vulnerability the agency had patched in 2019; it knew the info had been compromised however the state of affairs was out of its fingers. The unknown hacker then, final yr, created the database utilizing this stolen data and established a enterprise on Telegram whereby customers paid a small price to question the database and discover telephone numbers linked to Fb profiles. Regardless of this endeavour, the hacker modified tack and dumped all of it on-line in April.
Colonial’s Pipeline runs dry
The double-extortion ransomware siege on Colonial Pipeline was among the many most widely-reported assaults of 2021 because of the sheer scale of affect it had on US infrastructure.
The agency managing the 5,500-mile pipeline between Texas and New York, tasked with delivering 45% of the East Coast’s gas, was delivered to its knees for six days, with provides minimize off, in Might. Russian-linked DarkSide took credit score, having beforehand offered details about its assaults to inventory merchants the previous month.
DarkSide additionally threatened to leak data from the 100GB of knowledge it stole earlier than locking down the corporate’s programs. For shoppers, restricted gas provide meant US residents needed to bodily compete with each other for assets, as a hoarding craze took maintain.
Earlier than lengthy, Colonial Pipeline went towards cyber safety finest apply and paid the ransom, reported to be $4.4 million (roughly £3.3 million). The Division of Justice (DoJ) eventually recovered most of this sum, however the worry of future assaults catalysed a shift in focus for policymakers. Stricter rules round securing pipelines from cyber assaults have been swiftly launched, and the incident prompted the Biden administration to advertise ransomware to ‘terrorism’ status. The assault was so dangerous that even DarkSide was compelled to vary its operation, specifically introducing a moderation process following an enormous backlash.
Kaseya provide chain assault cripples hundreds of thousands of gadgets
The summer season months have been marred with one more mass-scale cyber assault, this time on Kaseya’s VSA product, a instrument Managed Service Suppliers (MSPs) use to watch their shoppers’ IT wants. The wrongdoer, REvil, focused a zero-day flaw in VSA specifically attributable to performance that allowed IT managers to push updates to shoppers with out intervention.
Sarcastically, Kaseya had been working with Dutch safety agency DIVD CSIRT on the time to patch the flaw REvil finally exploited; this was a race towards the clock the researchers sadly misplaced. Kaseya first introduced 50 prospects have been affected however, in actuality, the ransomware hit more than 1,000 victims and crippled greater than 1,000,000 gadgets. This isn’t to say REvil’s gargantuan reported ransom demand of $70 million (roughly £52 million) for supplying the common decryptor.
What adopted was a complete shut down of VSA servers, with researchers finally patching the three zero-day flaws that facilitated the assault. Opportunistic cyber criminals, although, continued by capitalising on the mayhem with specialised phishing campaigns purporting to produce system-fixing updates from Kaseya. Weeks later, Kaseya obtained a decryptor through a third party, insisting no cost was made.
Curiously, REvil shut down days after the assault; its servers and web site have been rendered offline. The group, nevertheless, returned in September by reopening its ‘Completely satisfied Weblog’ – a web site on which victims who refuse to pay are named and ‘shamed’ – earlier than vanishing once more in mild of a Europol-led sting operation.
PrintNightmare: A comedy of errors
The aptly-named PrintNightmare fiasco arose at the start of July after a devastating misunderstanding led to a good cyber safety vendor, Sangfor, inadvertently publishing a working exploit for an unpatched vulnerability.
Microsoft had initially patched a privilege escalation vulnerability in its Print Spooler component on 8 June as a part of its routine Patch Tuesday wave of updates. The agency, nevertheless, two weeks later upgraded the severity of the bug to distant code execution (RCE). The vulnerability in query allowed attackers to put in functions, view, change or delete knowledge, or create new accounts with full privileges on focused gadgets.
Sangfor researchers, in the meantime, have been conducting their very own analysis into Print Spooler vulnerabilities, forward of a presentation on the Black Hat cyber safety convention in August. When Microsoft upgraded the severity of the now-patched PrintSpooler flaw, the researchers revealed a proof-of-concept exploit for an RCE flaw forward of time, mistakenly believing this to be the identical vulnerability that Microsoft had patched in June.
By the point Sangfor realised this error and took its report down, the exploitation was already being distributed throughout the hacking group.
Microsoft promptly issued a patch, however this finally proved unsuccessful, after one other researcher revealed a workaround. Then, the agency launched a working patch on its second try on 13 July, alongside fixes for 117 different flaws.
Emotet buried by Europol – then rises from the ashes
Emotet was undoubtedly one of the crucial devastating strains of malware ever authored; at its peak, it supplied an entry level for as much as 70% of malware strains in international circulation. The notorious banking Trojan’s significance and effectiveness was incontrovertible, however Christmas got here late for safety groups in January as a coordinated regulation enforcement effort, led by Europol, took it down for good.
That was, at the least, the road they touted on the time. Europol officers, alongside colleagues from the UK, US, and France, seized a number of hundred servers comprising Emotet’s infrastructure. It was an enormous reduction, given the malware was, as of a month earlier, affecting as much as 100,000 users per day. German authorities later used the seized Emotet servers to uninstall the Trojan from contaminated gadgets – a dagger to the guts.
This transient interval of bliss lasted simply six months, nevertheless, with researchers discovering a retooled iteration of Emotet re-emerging in the wild. Again with better-protected code and infrastructure, safety consultants at the moment are, as soon as once more, on excessive alert, warning workers of the telltale indicators of Emotet-infected emails. Whether or not this resurgent pressure turns into as prolific as its predecessor stays to be seen, but it surely’s actually a comeback that’s despatched shockwaves via the safety group.
Log4Shell is a real nightmare earlier than Christmas
Found simply weeks earlier than the yr’s finish as a glitch in Minecraft, of all locations, chatter continues to run rife within the infosec group about simply how harmful the flaw generally known as Log4Shell may very well be.
Log4Shell is a zero-day vulnerability within the common log4j 2 library, a logger that’s virtually ubiquitous in international Java apps and enterprise merchandise. Apache frameworks, together with Apache Struts2, Apache Solr, Apache Druid, and Apache Fline, are regarded as notably susceptible. There are, nevertheless, merchandise being discovered to be susceptible with every day that passes since its 9 December discovery.
Whereas the overwhelming majority of merchandise written in Java are regarded as susceptible to the RCE tracked as CVE-2021-44228, the true breadth of the assault floor continues to be but to be confirmed and isn’t more likely to be absolutely realised for months, in keeping with consultants. Attackers, nevertheless, can actually utilise a long-known exploitation methodology generally known as Java Naming and Listing Interface (JNDI) injection to attain RCE.
There are presently no identified main exploitations of the vulnerability, however early proof factors to Mirai botnets being launched utilizing susceptible infrastructure, with different assaults seemingly. To that impact, Test Level researchers noticed more than 800,000 attack attempts utilizing the vulnerability inside 72 hours of disclosure. With patches accessible, it’s set to be a turbulent and anxious few weeks for cyber safety professionals throughout the globe because the trade watches the potential horrors unfold.
