--Ransomware Attack Hits Electric Power Provider in Johannesburg

(July 25, 2019)

A ransomware attack that hit systems at City Power, a pre-paid electric power company in Johannesburg, South Africa, has left some residents there without electricity. The attack has affected City Power's database, internal networks, website, and web apps. City Power is owned by the city of Johannesburg.

--Three Louisiana School Districts Suffer Ransomware Infections, Governor Declares State of Emergency

(July 25, 2019)

Louisiana's governor has declared a state of emergency after three school districts there were hit with ransomware attacks. The declaration makes certain state resources, the Louisiana National Guard and the Office of Technology Services, available to the affected school districts. This is believed to be just the second time a US governor has declared a state of emergency related to a cyberattack. In early 2018, Colorado's governor declared a state of emergency when systems at the Colorado Department of Transportation were infected with ransomware.


[Editor Comments]


[Honan] Today is the 3rd anniversary of the launch of the No More Ransom initiative by Europol. In the past three years NoMoreRansom has helped over 200,000 victims, prevented criminals from earning US$108,000,000 and covers over 100 ransomware families.

 --VPN Flaws Affect Widely Used Products

(July 23, 2019)

Critical flaws in popular virtual private networks (VPNs) could be exploited to gain access to corporate networks and steal data. The flaws are easily remotely exploitable; they affect VPNs from Palo Alto Networks, Pulse Secure, and Fortinet. All three have released advisories and updates to address the issues. Devcore researchers plan to discuss their findings about the flaws at the Black Hat security conference next month.


[Editor Comments]


[Pescatore] This is a good reminder about the importance of a complete and accurate software inventory. Patches for this vulnerability have been out for a while but often tools or components like VPN software are overlooked.


[Neely] While the patches have been out for a bit, scans found many devices online still running the vulnerable code. Make sure that your boundary protections, including VPN, Firewalls, IDS/IPS are in your maintenance schedule with priority for updates. You may need to acquire non-production units to satisfy regression testing requirements.

--BlueKeep Exploit Instructions Posted Online; Exploit Included in Company's Pen-Test Toolkit

(July 22, 24, & 25, 2019)

Information posted to Github offers directions for exploiting the BlueKeep vulnerability, and a US security company says it is including a BlueKeep exploit in its pen-testing toolkit. Several weeks ago, cybersecurity firm BitSight estimated that more than 800,000 Windows machines had yet to be patched against BlueKeep. The issue affects Windows XP, Vista, Windows 7, Server 2003, and Server 2008. Microsoft released patches in mid-May.


[Editor Comments]

--Vulnerability in Third-Party Library Was Fixed in VLC 16 Months Ago

(July 23 & 24, 2019)

A critical heap buffer overflow flaw that was initially reported to affect VideoLAN's VLC media player actually affects a third-party library. VLC developers say that their product is not vulnerable and that that "the issue is in a 3rd party library, called libebml, which was fixed more than 16 months ago. VLC since version 3.0.3 has the correct version shipped."

--Prison Sentence for Man Who Hacked iCloud Accounts

(July 18, 19, & 23, 2019)

A US District Court Judge in Georgia sentenced Kwamaine Jerell Ford to 37 months in prison for breaking into Apple accounts that belonged to well-known professional athletes and rappers. Ford spent more than US $300,000 using financial information he obtained from the accounts. He was convicted in charges of computer fraud and aggravated identity theft.

--Google Bans Dark Matter Certificates

(July 23, 2019)

Google has joined Mozilla in banning DarkMatter root certificates. Mozilla banned the certificates from Firefox at the beginning of July, citing concerns that DarkMatter might abuse the privilege of being on the Firefox certificate whitelist. DarkMatter is a cybersecurity vendor based in the United Arab Emirates (UAE). The organization has reportedly carried out surveillance operations targeting journalists, governments, and human rights activists.

--NSA to Create Cybersecurity Directorate to Improve Cyber Defense

(July 23, 2019)

The US National Security Agency (NSAA) will establish a cybersecurity directorate later this year. The creation of the directorate will allow the NSA to share information obtained by signals intelligence with other government agencies and with private sector organizations. The directorate is scheduled to become operational on October 1, 2019.  (Please note that the WSJ story is behind a paywall.)


[Editor Comments]


[Neely] The initiative includes reorganization of their web pages to create a one-stop-shop for vulnerability information, uploading malware samples to VirtusTotal, and posting their own research and threat warnings. They expect to incorporate lessons learned from other agencies' efforts and from the private sector.

--Man Arrested for Allegedly Trying to Launder Cryptocurrency Obtained Through Narcotics Trafficking

(July 18 & 23, 2019)

US federal authorities have arrested an Ohio man for allegedly attempting to launder US $19 million in cryptocurrency that he earned from drug deals on the now defunct Silk Road dark web market. Haney has ben charged with one count of concealment money laundering and one count of engaging in a financial transaction in criminally derived property. Haney allegedly moved the bitcoin proceeds to a cryptocurrency exchange and claimed that he obtained the funds through cryptomining. However, authorities say they can trace the blockchain transactions back to the Silk Road. When Haney converted the cryptocurrency to cash, federal agents seized the funds and arrested him.

 

[Editor Comments]


[Neely] This points out the risk of the intersection of cryptocurrency and traditional currency when reporting the source of funds. The conversion to cash was a visible transaction which allegedly allowed DHS to trace the Bitcoin blockchain back to its origin. Kudos to DHS for developing this capability, and a reminder of the importance of good operational security.

--Facebook to Pay $5 Billion Penalty

(July 24 & 25, 2019)

At a press conference on Wednesday, July 24, the US Federal Trade Commission announced that Facebook will pay a $5 billion penalty for violating consumer privacy. The FTC does not find anyone personally responsible for the violations, nor does it impose significant changes to the way Facebook collects data.  


[Editor Comments]


[Pescatore] A lot of the political and press reaction was that the fine was too low, because it is "only" about 8% of Facebook's revenue run rate. That is twice as much as the European GDPR compliance regime allows and is definitely a board-level attention getter. It is also not the end of the impact on Facebook, and other tech companies, as both the political and market forces in the US are starting to move more towards requiring the "opt-in/informed consent" model that Europe has long used, vs. the "trick the user into not opting-out" model long in use in the US.


[Neely] The focus here is on changes to privacy data gathering and consent processes rather than the amount of the fine. As privacy legislation continues to evolve, active rather than passive consent, with the right to rescind, must become SOP.
