--Microsoft Patch Tuesday Includes Fixes for XP and Other Unsupported Systems

(May 14, 15, & 16, 2019)

Among the many fixes in Microsoft's Patch Tuesday for May are patches for a critical remote Desktop Services vulnerability in Windows XP and other systems that Microsoft no longer actively supports. The last time Microsoft released a fix for XP was two years ago, when WannaCry was making the rounds. Microsoft says that this vulnerability poses an equally serious threat. The flaw can be exploited by connecting to a vulnerable device over the Internet. Microsoft has also made fixes available for Windows 2003, Windows 7, and Windows Server 2008. The issue does not affect Windows 8 or Windows 10. An estimated 3.57 percent of Windows machines are still running Windows XP, which translates to tens of millions of machines, some of which are in systems at hospitals and industrial plants.

[Editor Comment]

[Neely] Per the Microsoft bulletin, there is no mitigation or workaround for this vulnerability. Even so, consider systems that offer RDP services directly to the Internet as the exploit can be triggered by anonymously sending a specially-crafted packet to the system.


[Honan] If Microsoft are taking the threat relating to this vulnerability seriously enough to issue a patch for Windows XP, then that should be the warning you need to treat this seriously and apply those patches.

--Executive Order Gives Commerce Secretary Authority to Ban Use of Certain Technologies

(May 16, 2019)

The White House has used an executive order to declare a national emergency that grants the Secretary of Commerce the authority to prohibit American companies from purchasing certain companies' communications technologies. The order also gives the Commerce Secretary the authority to establish an enforcement framework.

--Lessons from Colorado's DOT Ransomware Attack

(May 15, 2019)

Ten days after Colorado's Department of Transportation was hit with SamSam ransomware in February 2018, the governor declared the incident a disaster, allowing the state to bring in help from the National Guard and from other states and to create a unified command structure to help establish recovery priorities. It was the first time a cyberattack had been declared a disaster.

[Editor Comments]

[Neely] This highlights a need for updating disaster plans as well an effective path to obtaining needed resources, paving the way for other states to better respond to future incidents.

--Google Will Replace Misconfigured Bluetooth Low Energy Titan Security Keys

(May 15, 2019)

A misconfiguration in the Bluetooth Low Energy version of Google's Titan Security Key could be exploited to communicate with the key or with the device to which the key is paired. An attacker would need to be within 30 feet of the targeted device. Google will replace affected devices at no cost.

--New Class of Flaws Affects Intel Chips

(May 14 & 15, 2019)

Intel has disclosed a new class of speculative execution side-channel attacks affecting its processors. The attacks differ from Meltdown and Spectre and their variants because they could leak data from CPU buffers. Intel calls the flaws Microarchitectural Data Sampling, or MDS. The flaws have been addressed at the hardware level in more recent released of Intel products, and Intel has released microcode and hypervisor updates.

[Editor Comments]

[Neely] As researchers assess other ways speculative execution can be abused, expect more MDS family types of flaws. These are currently low risk due to the degree of difficulty to exploit. Beware of attention getting names, and accompanying icons, like ZombieLoad, that shift focus from the true risk to the headlines.

--Microsoft Patch Tuesday

(May 14 & 15, 2019)

Microsoft's monthly security update for May includes fixes for nearly 80 vulnerabilities, 19 of which are rated critical. One of the flaws, a privilege elevation issue in the Windows Error Reporting service, is already being exploited in the wild. Microsoft has also released an advisory explaining its mitigation plan for the MDS attack issues that Intel disclosed earlier this week.  

[Editor Comments]

[Neely] The mitigations for MDS attacks will require both firmware and OS changes. The firmware updates are not available yet. When released, test for system impact before rolling across the enterprise.

--International Effort Takes Down Cybercrime Group

(May 16, 2019)

Law enforcement authorities in Bulgaria, Germany, Georgia, Moldova, Ukraine, and the US, along with Europol, worked together to take down a cybercrime group that reportedly attempted to steal US $100 million from businesses and financial institutions. Five members of the group have been arrested; another five remain at large. US federal grand jury returned a criminal indictment charging 10 individuals with various offenses. A Europol statement says that the operation "exemplified the concept of "'cybercrime as a service.'"

[Editor Comments]

[Honan] This is a good example of how criminals cooperate across borders. On the flip side, it is great to see that effective international cooperation works for those on the side of good, as well.

--San Francisco Bans Facial Recognition

(May 14 & 15, 2019)

The City of San Francisco, California's Board of Supervisors has approved an ordinance that prohibits law enforcement and other city agencies from using facial recognition technology on city residents. The ordinance notes that "the propensity for facial recognition technology to endanger civil rights and civil liberties substantially outweighs its purported benefits." The ordinance also requires that law enforcement disclose what kinds of surveillance they are using.

--Fighting Back Against IP Address Scams

(May 15, 2019)

The American Registry for Internet Numbers (ARIN) revoked more than 750,000 IPv4 addresses that had been fraudulently obtained and in many cases, resold to spammers. The entity identified as having fraudulently obtained and resold the IPv4 addresses has been charged in federal court with twenty counts of wire fraud and has been ordered to pay ARIN USA $350,000 for its legal fees.

--Some Ransomware Recovery Companies Have Been Paying the Ransom

(May 15, 2019)

At least two companies that advertise data recovery services for ransomware victims have actually been paying the ransom. The companies often charge their clients high fees in excess of the cost of the ransom. While there are companies that openly pay ransom - often they help victims who are unfamiliar with dealing in cryptocurrency - it is not clear that other companies were forthright with their clients about their methods.
